Logo Design: Guides for Process, Mistakes, and Scalability, Tested at Favicon Size and in One Colour

Most writing about logo design is aimed at people who want to look at pretty pictures, not at people who have to deliver a working file to a printer, a developer, or a client who just emailed a question from their phone. The common assumption is that a logo is an image, and the job is done when it looks good on a white screen at full size. That assumption is why so many brands end up with a logo that works on the homepage and fails at 16 pixels, or that survives a website launch but dies in a single-colour embroidery file. A logo is not an image at all. It is a set of specifications that must survive a gauntlet of hostile production environments, and the two most hostile are the favicon and the one-colour print.

This is the index page for the logo design guides here. It routes you to the specific guide that answers the question you actually have. You are not here to browse. You are here because you either need to design a logo from scratch, you have a logo that fails when it hits production, or you want to avoid the errors that cause expensive rework. This page tells you which guide to open, and it states the contract that every guide beneath this one must honour. That contract is simple and non-negotiable: every recommendation in every logo design guide on this site must survive two tests. The first test is rendering legibly at 16 by 16 pixels, the standard favicon size. The second test is communicating the brand in a single flat colour, the condition for fax, embroidery, and low-cost print where a logo must function without gradients, screens, or fine lines. If a recommendation fails either test, it does not make it into these guides.

The Two Constraints That Define A Logo

Those two constraints are not arbitrary. The favicon is the smallest standard production size your logo will ever be rendered at, and it appears everywhere: browser tabs, mobile bookmarks, address bars, and the mobile home-screen icons that users stare at all day. If your logo does not work at that size, you do not have a brand mark. You have a poster you are pretending is a logo. The one-colour requirement is the equal-and-opposite failure mode at the other end of the production spectrum. Embroidery machines lay down thread one colour at a time. Fax machines, still used in health care and government, reduce everything to a single channel. The cheapest print job your client ever buys will be a single-ink run, since it costs a fraction of a four-colour process. Your logo has to survive that too. If it cannot, it is a drawing, not a logo. The page you are on now is the map; the guides you will be routed to are the territory. If you only need one rule to remember, it is this: design in vector format, test in raster reality, and never let a gradient onto your source file unless you have already seen it die in one colour and said yes to it anyway.

The philosophy of this entire section is that the logo is the brand's primary asset, and assets must be files before they are feelings. That is why the guides here speak the specification language, not the mystique language. You will not find a claim that a logo has "weight" or "presence" unless there is a measurable property behind the word, like x-height or safe area. You will find instructions to check the contrast ratio against WCAG 2.2 before you send a white mark to a client who insists on a light-grey background. This page is the hub. The guides are the spokes. The person who needs this page is not the casual reader. It is the hardworking non-design professional who is the only design-literate person in the building, and who needs somewhere to point when the boss demands to know why the logo is not legible on the favicon. You point to this page, and then you point to the specific guide that has the numbers.

The Standard No Other Blog Meets

Here is the one thing that makes this section of the site different from every other logo blog on the internet. Hold onto it as you read: the common thread is that we approach logo design as a craft body of knowledge, not as a personality-driven field. You will not find portfolios of "inspiring" work. You will not find lazy articles about the emotional resonance of the colour blue. You will find the exact file format, the exact minimum size, the contrast ratio, and the failure mode that occurs when someone ignores them. The cost of ignoring this is not a bruised aesthetic ego. It is the real cost of a reprint rejected by the press because the rich-black misregistered, or the app update that gets rejected because the touch target size was too small and the favicon was indistinguishable from the competition. Decide now which problem you are solving: you are either building a logo from scratch, fixing a logo that fails, or avoiding the common errors. Then pick your route from the table below.

If you are starting with a blank canvas, know that the design phase is the cheapest phase to change your mind. The most expensive error in design is not a bad idea. It is a good idea rendered in the wrong file format. A raster-only logo is a source-file failure before it has ever been used. You must design in vector format, which means SVG, EPS, or AI, and you must understand the difference between raster and vector. Raster images are pixel grids that degrade when scaled. Vector images are mathematical paths that remain sharp at any size. A logo drawn in Photoshop is a picture of a logo. A logo drawn in a vector editor is a logo. If you need this distinction explained, start with the guide that covers the design process from scratch. It will walk you through the difference between a symbol and a wordmark, and it will tell you why you need both variants before you even think about a colour palette.

The alternative starting point is that you already have a logo and it is failing. Maybe it fails because it is unreadable at favicon size. Maybe it fails because the one-colour version looks like a blob. Maybe it fails because your production team is asking for files you do not have. This is the scalability testing problem, and it is the most common reason logos get redesigned. Not because the design is ugly, but because it was never tested at the sizes where it actually lives. The guides here will walk you through the legibility threshold, the size at which your logo stops being readable. They will give you the exact method for testing it. Do not zoom into your screen until it looks good. Print it small, render it at 16 by 16 pixels, and look at it in greyscale.

Finally, if you are here because you want to avoid the rework that comes from common errors, you are the smartest reader on this page. The guides will cover the specific failure modes that kill logos: contrast-failure rejection, rich-black misregistration, and the absolute killer, which is designing in a colour gamut your output device cannot reproduce. Every one of these is a preventable, named error with a cause and a fix. You do not need to make these errors yourself to learn from them. You need to recognise the failure mode when you see it, so you can stop it before it costs a print run.

What These Guides Will Not Do

Let me make one thing clear about who this section is not for. There are plenty of sites that will sell you colour psychology as a primary decision-making framework. This one only addresses colour where evidence exists, which is legibility and accessibility research. There are sites that treat logo design as a pathway to "inspiration". This one treats it as a discipline with a spec sheet. And there are sites that are basically design software catalogues. This one only names a tool when it defines a file format or a specification, and it will never tell you what anything costs because pricing is not stable. You already know this: a search for "logo design" on a general engine returns a wasteland of aggregated listicles that all say the same four things. You are on this page because you want the version where the advice is specific enough to act on and the numbers are specific enough to verify.

The core principle is the style guide. Think of it as the rulebook for how the logo is used. The best logo in the world will look like a mess if it is placed on a busy background, shrunk below its minimum size, or placed too close to other elements. The style guide is where you enforce the clear space and the minimum size, and where you define the safe area for print. If you are an in-house designer advocating for a style guide to your boss, you are not being precious. You are preventing the death of the brand by a thousand small cuts on social media profile pictures. The guides here will show you what goes into that document, from the exact hex codes to the one-colour versions for fax and embroidery.

The truth is that this is a lot of work, and the work does not end when the logo is approved. It ends when you watch a developer implement your SVG into a web page without breaking the file weight, or when a printer asks for the EPS and you send it without a second thought because you have the source file. The work is not glamorous. It is the difference between a brand that looks professional everywhere and one that falls apart at the first point of friction. If you are not willing to do that work, if you are not willing to test the logo at 16 pixels and in one colour, then you are not designing a logo. You are making a poster you will be embarrassed by the first time a client uses it on a pen. Avoid that fate by choosing your route.

The one piece of advice before you click through is this: start with the scalability testing guide, regardless of whether you are designing from scratch or fixing a failure. The reason is that every other decision you make, from the typeface you choose to the amount of stroke weight on your mark, is a consequence of how it behaves at small size. You will save yourself a week of rework if you learn the legibility threshold before you fall in love with a logo that cannot survive it. So read that guide first. Then read the one that matches your current situation. If you are designing from scratch, that is the next stop. If you are fixing a failure, you will already know which guide you need.

When A Logo Is Finished

Now, let us be honest about the limitations. This section will not teach you how to draw. It will not teach you how to be more creative, because creativity is not the bottleneck for the people who need this page. The bottleneck is the discipline of knowing when a logo is finished, and "finished" is not a feeling. It is a checklist. You will know the logo is finished when it passes the favicon test, when it works in one colour, and when you have the vector source files saved in an organised manner. This is the boring, practical, essential work that separates a professional brand from a hobby. The good news is that this work is teachable, and the guides under this hub exist to teach it to you. The bad news is that no one on the internet can do it for you, regardless of how many templates you buy.

Before you go, understand one more thing about the advice here. You will never see a claim that a certain tool is "essential" or that a certain technique is "best practice" based on a blog post. Every claim is held to the standard of the two tests. If a practice does not demonstrably improve the logo's performance at favicon size or in one colour, it is not in the guide. That means you will sometimes find advice that contradicts the consensus of design blogs. That is fine. The blogs are not paying your print bill. So if you find yourself agreeing with everything in the guide, you are not reading carefully enough. Look for the place where the guide tells you something is overrated, or crowded, or not worth the detour. That is where the truth lives.

Here is the caveat that every professional in this industry will recognise: the rules are not universal. A logo for a financial institution that needs to be conservative can get away with a serif wordmark that would be a disaster for a gaming company. The constraints of the favicon and one colour are universal. The response to those constraints is not. The skill is knowing when the rules can be bent, and the guides will tell you when the rules are actually hard. What they will never do is tell you that the rules do not apply to you, because that is the thinking that leads to a logo that fails. The only person who can make that call is you, and you will make it better if you know what the rules are for.

The final decision you need to make is not about the logo at all. It is about which problem you are going to solve today. The page you are on is the hub, and it is intentionally short because its job is to route you, not to hold your hand. If you are designing a logo from scratch, you need the process guide. If you are fixing a failure, you need the scalability testing guide. If you are trying to avoid the errors, you need the errors guide. There is no wrong answer among those three. There is a wrong answer in not picking one and starting. The most important step in any design project is not the first sketch. It is the decision to commit to a process. This site is the process. The rest is just work, and the work is worth it.

The Favicon Test And The One-Colour Rule

Here is a summary of the most important advice in this section, the kind of practical detail missing from those listicles: the favicon test is not a suggestion. Before you finalise any logo, create a 16 by 16 pixel version and look at it. Not zoomed in. Not squinting at it. At actual size. If you cannot tell what it is, you have two choices: simplify the mark until you can, or accept that the favicon will be abstract. The latter is a choice, but it is a choice with a cost, because the favicon is the one place where your brand appears in the browser tab next to your competitors. If you are undecided about whether to use a symbol or a wordmark, let the favicon decide for you. The symbol that scales down well will win every time, because the wordmark that works at the largest size will be a blur at 16 pixels.

The most dangerous words in the design brief are "we can fix it later". You cannot fix a logo that was not designed for small sizes by adding more detail later. You can only strip detail away, and at some point, you have stripped away so much that you do not have a logo. You have a generic geometric shape. The only way to avoid this is to design for the constraint from the beginning. That means starting with a simple mark, or starting with a wordmark that has a strong x-height, and testing it early. The guides will walk you through this, step by step, with the actual numbers you need. The contrast ratio. The minimum size. The clear space. All of it is there, waiting for you.

The best time to start is now. The best place to start is the scalability testing guide. It is the foundation for everything else in the section, and it is the guide that will save you the most money because it prevents the most rework. After you have read it, you will not see logo design the same way again. You will see it as a series of constraints. You will stop worrying about whether the logo is "creative" and start worrying about whether it is legible. That is the shift that makes the difference between a professional and an amateur, and it is the shift that this entire section is dedicated to making for you.

One last honest caveat: no guide can tell you when a logo is "done" in a way that satisfies everyone. Design is subjective. There will always be a stakeholder who wants the logo to be bigger, smaller, or a different colour. What the process does is give you a defensible position. When the stakeholder asks you to shrink the logo below the minimum size, you can show them the legibility threshold. When they ask you to use a gradient in the favicon, you can show them what happens in one colour. The process is not about making design decisions for you. It is about giving you the ammunition to defend the decisions you make. That is the value of the guides under this hub, and that is what you get when you choose to work with a specification instead of a feeling.

You now have everything you need to know to choose your own adventure. The table below will help you match your goal to the right guide, and the FAQ section after it will answer the most common questions people have before they start. Read that, then go. There is no reason to read every word of this page again. The value is in the specific guide you are about to open.

This is the part where most articles would tell you to "enjoy the process". I am not going to do that, because the process is not always enjoyable. It is often frustrating, and it requires you to be honest with yourself about the constraints of the medium. But it is worth it. When you see your logo rendered perfectly at 16 pixels, legible and clear, and then you see it stitched into a polo shirt in a single colour, you will feel something that no amount of "enjoyment" can provide. You will feel the satisfaction of having done it right. That is the real reward.

So start there, at the beginning, with the process guide, and work your way through the section in order. Not because you need to read everything to understand the whole, but because each guide builds on the last. The vocabulary you pick up in the first one will make the later ones easier to understand. This is how you learn a craft, and this is how you build a brand that lasts.

Go to the guides, and remember the two tests. They are the only ones that matter.

This is the overview section. It exists to map the territory before you start digging. The logo design guides here cover three distinct journeys: starting from nothing, fixing what is broken, and avoiding the known failure modes. Each journey leads to a different guide. Do not read all of them. Read the one that matches your situation, and trust that the others will still be there if your situation changes. The section is organised around the idea that a logo is not a finished product until it has been tested. The section overview is where you learn how to navigate the maps.

For the professional who commissions design work, this overview gives you the vocabulary. If the designer hands you a logo and says it is a vector format, you know that means SVG, EPS, or AI. You know that a raster-only logo is a source-file failure. If the designer hands you a logo and says it will be fine in a favicon, you now know that you have to see it at 16 by 16 pixels before you believe it. This is where you learn to question the process, not to undermine it, but to ensure that the process actually happened. The guides are the tools. This overview is the toolbelt. For the educator or the bootcamp instructor, this is the canonical reference, the one you can cite to students who have read too many blog posts telling them that a logo's meaning is more important than its specification. It is not, and this section makes that clear.

The overview also covers the key distinction between the different types of marks. A symbol is a graphic device, like the Nike swoosh. A wordmark is a text-based logo, like Google. You need to know which one you have before you can test it effectively, because they fail in different ways. A symbol becomes a blob at small size. A wordmark becomes unreadable. The section overview explains this distinction and points you to the specific guide that addresses your problem. The only thing you will not find here is inspiration, because this is a documentation of constraints, not a celebration of visual style.

If you are a solo developer or a marketer who has been handed a logo and told to "make it work," this overview is your survival manual. It tells you what to ask for from the designer. It tells you what to check before you accept the file. It also tells you what to do when you receive a logo that is only a PNG. You are not being given a logo. You are being given a picture of a logo, and the real one is a vector file. The section overview is the place where you learn to tell the difference. It is the place where you learn to ask for what you need before you waste a week of your life trying to make a raster image work in a context that demands vector.

The practical takeaway from this overview is that the most important thing you can do for your brand is not to choose a colour palette. It is to establish a source file you can actually use. That source file is a vector format. It is the version of the logo you will use for every application that requires sharp edges. It is the logo that will survive the favicon test. It is the logo that will survive the one-colour test. Everything else is a derivative of that file, and the overview explains how to manage those derivatives. It is not the most glamorous work, but it is the work that makes the difference between a brand that is a professional asset and a brand that is a liability. Start here, and you will have already avoided the most common error that gets made in the design process.

This is the guide you need if you are starting from a blank canvas and you want to do it right the first time. The process of designing a logo is not about picking a font and drawing a shape. It is about establishing a system of constraints that will guide every decision you make. The process starts with research into the industry, the competitors, and the audience, but do not get lost in the analysis. The research phase does not have a finish line; it has a point of diminishing returns. The actionable step is to define the one thing the logo needs to be known for, and to write that down in a sentence. If you cannot write that sentence, you are not ready to design yet.

Building The Mark And The Wordmark

Once you have the strategy, the design phase begins with the wordmark and the symbol separately. You are not trying to create a masterpiece on the first pass. You are trying to create a family of marks that work alone and together. This is where the vector format becomes non-negotiable, because you will need to experiment with scaling, and you cannot do that with a raster file. The process guide walks you through building the file structure: the source file with layers, the export for web, the export for print. You will learn the difference between the source file and the delivered file. You will learn why you never give a client the source file unless you want them to edit it and send you back a mess.

The testing phase is where the process guide earns its keep. This is not a phase you do at the end. It is a phase you do during the design. Create a black-and-white version first, and test that version at favicon size before you even reach for a colour. The reasoning is that if the logo fails in black and white, it will fail in colour too. The colour is often masking a structural problem. The testing steps are concrete: create a 16 x 16 pixel version and view it at actual size. Print it at a small size to check the legibility threshold. Reduce it to one colour to check the contrast ratio. Each of these tests will take less than five minutes. Each one of them will catch a problem you would not have found otherwise.

Deliverables And The Handoff

The process guide also covers the deliverables you need to produce. It is not enough to have a single file. You need the primary logo, the variant with the symbol, the wordmark version, the monochrome version, and the favicon. Each of these is a separate file. Each one has a specific use case. The guide explains why you need a responsive logo, a version optimised for different sizes, and it explains why the clear space around the logo is just as important as the logo itself. The clear space is the area around the logo that must remain free of text or other graphics. It is defined by the height of the letter "x" or the height of the symbol. This is not a suggestion. It is a standard you will adopt to ensure the logo does not get visually crowded by the elements around it.

The final part of the process guide is the handoff. This is where you package all of the files, the source files and the exports, along with the style guide document. The style guide is the document that explains how to use the logo. It is a deliverable, not an afterthought. It should include the clear space, the minimum size, the colour values in RGB and CMYK, and the examples of what not to do. The guide will tell you what is included in the style guide, and it will tell you to budget for the time it takes to create it. If you are the one commissioning this work, expect a handoff that looks like this. Do not accept a delivery that is a single PNG file attached to an email. That is not a logo system. That is a clipart image.

The process is not linear. You will likely bounce between the design and the testing phases multiple times before you are happy. That is fine. What is not fine is skipping the testing. The one sentence that matters in this whole guide is this: a logo that has never been tested at favicon size is a drawing, not a logo. That is the entire philosophy. It is the core of the process. Once you have gone through the process once, you will understand why the guides in this section are so adamant about the two tests. You will never look at a logo the same way again.

You need this guide when you have a logo that works, until it does not. Maybe it looks great on the website, but it is a blur in the browser tab. Maybe it looks fine on a business card, but it is a smudge on the side of a pen. The problem is not the logo. The problem is that it was never tested at the sizes where it lives. This guide is about fixing that. It is the most important guide in this section because it prevents the most expensive error a brand can make: a logo that fails when it is put to work.

The Favicon Test And The One-Colour Test

Scalability testing is not a single test. It is a suite of tests you run at specific sizes and in specific media. The first test is the favicon. Create a 16 by 16 pixel version of your logo and look at it at actual size. Do not zoom in. Hold your phone at a normal distance and see if you can tell what the logo is. If you cannot, you have a legibility threshold problem. The second test is the one-colour test. Take the logo, remove all the colour, and see if it still communicates the brand. Do this before you even think about the gradient. The gradient is a crutch. The one-colour version is the truth.

The guide walks you through the exact method for each test. For the favicon, simplify the mark until it reads at 16 pixels. That may mean removing detail, increasing the stroke weight, or changing the shape entirely. The guide will give you the exact parameters for what works, based on the x-height of the typeface and the amount of detail in the symbol. For the one-colour test, check the contrast ratio between the logo and the background it sits on. Check it against the WCAG 2.2 standards. The W3C publishes the actual formula. The guide will tell you to look it up, because the contrast ratio is a number and you need to check it, not guess it.

You will also learn the difference between raster and vector in this context. A vector format scales without losing quality, but it still has a legibility threshold because the human eye has a limit to what it can see. A raster image will become a pixelated mess at small sizes. A vector can be scaled down to a point and then it will also fail. The point where it fails is the threshold. You need to know what that point is so you can set your minimum size. The minimum size is the smallest size the logo can be and still be legible. It is a number you will put in your style guide. This is a non-negotiable rule, not a suggestion.

Testing In Context

The guide also covers testing the logo in context. Create a mockup of the favicon in the browser tab. Create a mockup of the app icon on a phone screen. Create a mockup of the embroidery on a shirt. These mockups are not about making pretty pictures for your portfolio. They are about checking the real-world performance of the logo. The guide will tell you what to look for in each context. It will tell you what to do when the test fails. It will also tell you when to stop. At a certain point you are not fixing the logo. You are designing a new one, and that is a different project.

The final section of this guide covers the difference between scaling a logo down and scaling it up. Scaling up is rarely a problem, because a vector format will stay sharp. It can cause a problem if the logo has fine lines that become invisible when the logo is scaled up. Scaling down is where the problems live. The guide will give you the specific method for testing both directions. The takeaway is that scalability testing is not a one-time event. It is a process you repeat every time you change the logo. It is the process that ensures your logo does not fail when it is put to work.

This is the guide for the person who has seen the same logo design errors so many times they can name them before the article gets to the point. The errors are not about taste. They are about the consequences of ignoring the specification. The most common error is designing in the wrong format. You see it all the time: a designer produces a logo in Photoshop because that is the tool they know, and then they wonder why the client cannot use it on the side of a truck. The error is not the tool. It is the lack of a vector source file. The fix is to start in a vector editor, or to convert the file before you deliver it. There is no excuse for delivering a raster-only logo, and the guide will tell you exactly that.

The second error is ignoring the favicon. The guide calls this the "tragedy of the 16 pixels," because so many logos that look great at full size become a blurry mess at the size of a browser tab. The error is not designing for the smallest size first. The fix is to design the favicon as a separate exercise, and to test the logo at favicon size from the very beginning. The third error is the opposite problem: designing for the small size and forgetting the large size. A logo that is too simple will look weak and empty when it is printed on a billboard. It will not have the detail needed to be interesting. The fix is to design for a range of sizes, and to test at both extremes.

File Management And Colour Space

The fourth error is a failure of file management. You have the logo, but you do not have the source file. Or you have the source file, but it is a flattened Photoshop document that is impossible to edit. The error is not having the correct file structure in place from the start. The fix is to establish a naming convention, to save the source files in the correct format, and to make sure you can go back and edit the logo in the future. The fifth error is using the wrong colour space. You designed the logo on your screen in RGB, but the printer needs CMYK, and the conversion is not going to look the same. The error is not soft-proofing the colours before you send the file to print. The fix is to use the ICC Profile for the print destination, and to check the colour gamut before you finalise the file.

The sixth error is not creating a clear space around the logo. You place the logo on a busy background and it is immediately lost in the noise. The error is not defining the clear space in the style guide. The fix is to measure the clear space in relation to the x-height of the wordmark, and to enforce that rule every time the logo is used. The seventh error is using the wrong file format for the application. You send a JPEG to the manufacturer who asked for a vector file, and then you are surprised when the logo comes out pixelated. The error is not knowing the difference between raster and vector, and when to use each one. The fix is to always have the source file in a vector format, and to export a raster version only for specific uses where the file size is the primary concern.

The eighth error is a failure of accessibility. The logo has a low contrast ratio, and it fails WCAG 2.2 when placed on a background that is not white. The error is not checking the contrast ratio against the actual background colour. The fix is to test the logo on the lightest and darkest backgrounds it will be used on, and to adjust the colour until it passes the contrast ratio. The ninth error is using the wrong typography. The wordmark is set in a typeface that is not available on the client's system, and it gets substituted with a generic font. The error is not outlining the type in a vector format. The fix is to convert the text to outlines before you deliver the file, so it cannot be substituted by the wrong font.

The tenth error is the most common, and it is the one the guides are trying to prevent: thinking that the logo is just the mark. A logo is not a single element. It is a system that includes the symbol, the wordmark, the clear space, the minimum size, and the colour palette. The error is not creating a style guide to hold the system together. The fix is to create the style guide, and to treat it as a deliverable that is as important as the logo itself. The guide concludes with the warning that the most dangerous error is the one you do not see, because you were not looking. The fix is to use the process, to test early and often, and to be willing to throw away work that fails the tests. It is the only way to avoid the rework that costs money and time. It is the only way to ensure that the logo you designed is the logo that ends up in production.

Now that you have the lay of the land, it is time to be practical about the cost, the schedule, and the trade-offs. The guide you need to start with is the one that matches your current situation. If you are designing from scratch, you will pay in time, in the range of 20 to 40 hours of focused work, to go from brief to a set of files that pass the two tests. If you are hiring a designer, that time translates to money. The cost varies wildly by the experience level of the designer and the market. You are not getting a fair price from a person selling a logo for fifty dollars. You are not getting a safe price from a freelancer who cannot explain the difference between a symbol and a wordmark. Budget for the work. Do not be shy about asking for the source files at the end.

If you are fixing a logo that fails, the schedule is shorter but the emotional cost is higher, because you are admitting that the thing you have been using is not working. The fix is not always a redesign. Sometimes it is a refinement, where you adjust the stroke weight or increase the clear space. The guide will show you how to make that decision. If you are avoiding errors, the cost is the time it takes to learn the specification language. It is not the most exciting way to spend an afternoon, but it is cheaper than a reprint.

The only thing you should avoid at all costs is the "quick fix" mentality. No logo design guide can compress the process into a five-step recipe, because the process is iterative and you have to test each iteration. The guide you are about to read will give you the steps. It cannot give you the time. The time is the cost of doing it right, and it is a cost you should be willing to pay. If you are not willing to pay it, you are better off using a generic template and accepting that your brand will not have a custom mark.

The honest caveat is that the advice in these guides is not a substitute for a professional designer. If you are a non-designer reading this, you will learn how to ask the right questions. You will not learn how to design a beautiful logo from scratch. The guides are for the people who need to manage the process, to speak the language, and to ensure that the work meets the standard. If you are in that group, start with the scalability testing guide. It is the foundation for everything else. If you are a designer, start with the errors guide. It will remind you why the rules exist. And if you are a business owner, start with the overview, and then hire someone who can pass the two tests.

What is the single most important test for a logo? The most important test is the favicon test: rendering the logo at 16 by 16 pixels and being able to identify it. This is the smallest standard size, and it is where most logos fail because they are too complex.

What is a source file, and why do I need it? A source file is the editable version of the logo in a vector format, such as an AI, EPS, or SVG file. It is the master file you use to make any other version of the logo. Without the source file, you have a picture of the logo, not the logo itself. You will not be able to resize it without losing quality or edit it without starting over.

Why can not I just use the PNG file from my website builder? A PNG file is a raster image, a grid of pixels. When you try to scale it up, it becomes blurry and pixelated. A vector file is resolution-independent and can be scaled to any size without losing quality. The PNG is a version of the logo for a specific use, not the logo itself.

What is the difference between a symbol and a wordmark? A symbol is a graphic icon that represents the brand, such as the Apple logo. A wordmark is a text-based logo that spells out the brand name, such as the Coca-Cola logo. Many brands use both, and each has its own strength. A symbol is more recognisable at small sizes. A wordmark is more effective when the brand is new and the name needs to be memorised.

How do I know if my logo's colours will print correctly? Convert your colours from RGB (for screens) to CMYK (for print) and then check how the logo looks with a soft-proof. The soft-proof will show you the colour gamut difference between your screen and the printer. It will help you avoid the disappointment of the print looking completely different from your screen.

If you take nothing else from this page, take this: the entire logo design section is held to the standard that no guide can recommend a process, a technique, or a style unless it has already been proven to survive both a 16-by-16-pixel rendering and a single-flat-colour reproduction, which means the guides here will sometimes tell you to abandon a design that looks beautiful on a full-colour monitor because it cannot get past the favicon. That is the specific opinion that every other page in this subject area is too timid to state, because it requires the writer to have done the testing, not just the admiring. It is the difference between writing about logo design as a visual art and writing about it as a craft with a spec sheet.
