Why a 40-page brand book usually isn't the answer
Big agencies love a thick brand guidelines document. Dozens of pages covering logo geometry, colour theory, tone of voice principles, imagery philosophy, sometimes even instructions for how the logo should behave in a PowerPoint slide. For a large company with multiple departments and outside agencies all needing to stay in sync, that level of detail earns its keep.
For a small business with one owner, maybe a couple of staff, and one person handling most of the marketing, that document gets skimmed once and never opened again. It's not that the information in it is wrong, it's that it's more than anyone actually needs day to day. What you need is something you'll genuinely refer back to: a single page you can glance at before you make a flyer, a Facebook post, or a sign, that keeps everything consistent without becoming a chore to maintain.
What actually belongs on it
A style guide that gets used covers four things and not much more: logo usage, colours, fonts, and tone of voice. That's genuinely enough for most small businesses to stay consistent across a website, social media, print, and signage.
### Logo usage
Show the correct version of your logo, the minimum size it should be used at, and how much clear space needs to sit around it so it doesn't get crowded by other text or images. Then show what not to do: don't stretch it, don't recolour it outside the approved palette, don't place it on a background that makes it hard to read. A handful of "don't" examples prevents more damage than pages of "do" instructions, because people remember a clear mistake better than an abstract rule.
### Colours
List your core colours with their exact values: hex code for web and digital use, and CMYK for print. This is the single most useful thing in the entire document, because it's the detail that gets lost or guessed at most often. Without it, you end up with a slightly different blue on your website, your business cards, and your van signage, and none of them quite match.
Two or three core colours plus a neutral (usually a dark grey or navy for text) is enough for almost any small business. You don't need a full secondary and tertiary palette unless your brand genuinely calls for it.
### Fonts
Name the actual font (or fonts) used for headings and for body text, along with where to get them if they're not something that comes standard on most computers. If you're using a free Google Font, say so and link it. If a designer supplied you with a paid font license, note that too, so nobody accidentally licenses the wrong version later.
Keep it to two fonts at most: one for headings, one for body text. If your logo uses a third, more decorative font, note that it's for the logo only and shouldn't be used elsewhere.
### Tone of voice
This is the part small businesses skip most often, and it's often the part that matters most once more than one person is writing content for the business. A few sentences describing how you sound (plainspoken and direct, or warm and friendly, or sharp and professional) plus three or four words you'd never use and three or four you would, gives anyone writing a social post or an email a genuine reference point instead of guessing.
What you can leave out
You don't need a section on logo geometry or the mathematical grid it was built on. You don't need six pages of "brand story" and "mission statement" language that nobody outside the business will ever read. You don't need imagery mood boards with dozens of reference photos, a rough description of the kind of photography that fits your brand is enough.
If a section wouldn't change a single practical decision someone makes when creating something for your business, it doesn't need to be in there. Every extra page is one more reason the document gets ignored.
Putting it together yourself
You don't need special software. A single page in Canva, Google Docs, or even a well-organised PDF works fine, as long as it's laid out clearly enough to be useful at a glance. If you're working with a designer on a logo or website, it's worth asking them to hand over this one-page summary as part of the job. Most designers already have the information, colours, fonts, logo files, they just don't always think to package it into something this simple unless you ask.
If you're doing it yourself, start by pulling your exact colour hex codes from your existing logo file or website, note down whatever fonts are already in use, and write two or three honest sentences about how your business actually sounds when it's talking to customers. That's most of the work done already, it just needs to be written down in one place instead of living in your head.
Keeping it alive
A style guide is only useful if people actually look at it. Keep it somewhere obvious, a shared drive folder, pinned in your notes app, printed and stuck near your desk, rather than buried in an old email attachment nobody can find six months later. Update it when something genuinely changes (a new accent colour, a font swap), rather than letting it quietly go out of date while your actual branding drifts.
A one-page guide that's actually followed does more for your brand's consistency than an impressive-looking 40-page document sitting unopened in a drawer. If you want a hand putting one together, whether you've already got a logo and colours locked in or you're starting from scratch, I'm happy to help you get it down to the one page that'll actually get used.
