A brand guide, also called a brand style guide, is a short document that keeps your logo, colors, fonts, and voice consistent everywhere your business appears. For a startup, it is the cheapest way to look professional from day one. This guide explains what a brand guide is, what to include, and how to create one without an agency.

What is a brand guide?

A brand guide is a set of rules for how your business looks and sounds. It shows people, such as designers, developers, printers, and new hires, exactly how to use your logo and brand assets. Without one, a logo gets stretched, colors drift, and each new piece of marketing looks slightly different.

What to include in a startup brand guide

SectionWhat to write down
LogoMain logo, one-color version, reversed version, icon, minimum size, clear space around it
Logo misuseExamples of what not to do: stretching, recoloring, adding effects, placing on busy photos
ColorsPrimary, accent, and neutral colors with HEX, RGB, and CMYK values
TypographyHeading font, body font, sizes, and where each one is used
ImageryPhoto style, icon style, and any patterns or graphics
Voice and toneThree words that describe how you sound, plus a sample sentence
TemplatesSocial post sizes, email header, business card layout

How to create a brand guide without an agency

  1. Finalize your logo and files. Do not write a brand guide for a logo you may change next month.
  2. Record your colors. Copy the HEX codes from your logo file and add RGB and CMYK values for print. Keep the same values in your website code.
  3. Choose two fonts. One for headings and one for body text. Note the fallback font for when the main font is not installed.
  4. Show good and bad examples. Take a screenshot of correct logo use, then a screenshot of a stretched or recolored logo labeled "never do this." Visual examples are faster to read than rules.
  5. Write three voice words. For example: "clear, friendly, expert." Add one sentence that shows the tone.
  6. Save it as a shared PDF or doc. Keep it short. Five to ten pages is enough for most startups.

Common brand guide mistakes

Why startups need a brand guide early

Early on, the founder makes every design decision. As soon as you hire a designer, a developer, or a freelancer, the brand starts to drift. A brand guide lets new people work on your brand without asking you every time. It also helps investors and partners see that you think about your brand carefully.

Where to start

Choose your logo first, then write a one-page version of the guide this week. Expand it as your business grows. If you still need a logo, BuildMyLogo can help you create logo options free and download the files you need for your guide. For the file types to include, see our logo file formats guide.
