Brand guidelines arrive in two varieties. The good kind is a working document that people open when they are unsure. The bad kind is a 60-page PDF nobody has read since the launch party, which is used once a year to reject a business card.
The difference is not length or design quality. It is whether the document answers the questions people actually have while they are working.
Who is this document for?
Designers, mostly. Which means it has to answer the questions designers have, not the questions the brand owner finds interesting.
A designer working on a landing page at 6pm on a Thursday does not need your brand philosophy. They need to know which shade of navy, how much space to leave around the logo, what happens when the mark runs out of room, and what to do about a headline that will not fit.
A document organised around the brand's story will lose that designer in the first two pages.
The sections worth having
The mark, and every legitimate version of it. Primary logo, stacked, symbol only, one-colour, reversed on dark, and the minimum sizes. With the clear space rule stated as a measurement relative to the mark, not as a vague "generous space."
The clear-space rule, drawn. Not described. A diagram showing the mark with a unit of measurement, so it can be applied without judgement. This is the single most-used rule in any brand and the one most often left ambiguous.
The minimum sizes, in real units. "Do not use below 24px digital or 8mm print" — with the actual pixel and millimetre figures, and what to substitute when space is tight (usually the symbol alone).
A colour system, as a hierarchy. Not a palette on a page. Named roles: the primary that carries the brand, the secondary that supports it, the accent used sparingly, the neutrals for surfaces and text, plus semantic colours for success, warning and error with their contrast pairings.
Contrast pairings, tested. "White text on navy passes AA. Yellow on navy passes for large text only." That single line prevents most of the accessibility failures we see in brand implementation.
Typography, as a scale. The typeface names with the source, the weights available, the size and line-height scale, and what to do when the licence does not permit the preferred weight. Licence reality matters more than designers expect.
Photography and illustration principles. What the imagery should feel like, with four or five reference images and three or four things to avoid. "Warm, natural light, real spaces, people mid-task" beats "authentic and on-brand" every time.
Voice, with examples. Three or four principles, each shown with a before-and-after sentence. "Say what you mean" is useless; "We will tell you the price on the first call" is a rule.
Layout and spacing basics. Margins, grid, alignment, how logo and type sit together, the minimum clear space in a layout. Enough that two designers produce recognisably similar work.
Application examples. Real assets — a business card, an email signature, a slide, a social post. Because specifications get misunderstood and examples do not.
The file library. Where the source artwork lives, what format is for what, and who to ask for what is missing. This is the section that gets used most often and is most often missing.
The three that waste your money
The 40-page logo construction section. Detailed grids, ratio studies and geometry. Occasionally useful to a designer who needs to redraw the mark; almost never worth a page each in a document meant to be skimmed.
Extensive mood board photography. Hundreds of images with no principle attached. It sets a mood for about a week and then sits there. Four images and a sentence will do more.
A mission statement and brand story. Put it on page one of the deck if you like. In a working document, it takes up space that rules should occupy.
How to make people actually use it
Keep it short. If it is over about 30 pages, it will be skimmed. Aim for the shortest document that still answers every question you would otherwise get asked by email.
Make it searchable and skimmable. Clear headings, a contents page, consistent naming for colours and fonts. Someone should be able to jump to "colour" in under five seconds.
Put it where the work happens. Figma library, a shared drive folder with the assets, and the relevant sections linked from wherever your team actually works. A guideline in a PDF nobody can find is a guideline that does not exist.
Give it an owner and a review date. Brands drift. A document reviewed once at launch and never again describes the brand as it was at launch. Put a date on it and a name against it.
Test it with one real outsider. Give it to a designer who has never worked with you and ask them to build a landing page from it. Whatever they get wrong is a gap in the document, not a failure by them. This is the single most effective test I know, and it takes an afternoon.
A reasonable length
For a small business, twenty to thirty pages is genuinely enough. For a larger organisation with multiple sub-brands, sixty is reasonable. The number that is not reasonable is "as long as the agency could make it."
A common and effective structure:
- Cover
- Contents
- Logo — versions, clear space, minimum sizes, misuse
- Colour — roles, hex and print values, contrast pairings
- Typography — families, scale, pairing
- Photography and illustration
- Voice — principles and examples
- Layout and applications
- Files and contacts
That is the document. Everything else is optional.
We include brand guidelines with the Signature branding package, structured this way, and we deliberately do not include them with the Essential one. If your business is small and the work is being applied by one or two people, a one-page colour and type guide does the job better than thirty pages nobody opens. If you want ongoing support keeping the brand consistent, Brand care covers exactly that.
