A practical checklist of what belongs in a brand guidelines document — and what makes teams ignore the one they already have.
Useful brand guidelines include logo suite and clear space, colour values in every colour space, typography and a type scale, layout and grid rules, photography and illustration direction, tone of voice with real examples, application examples, and misuse examples. Anything longer than about forty pages usually stops being used.
Most brand guidelines fail for the same reason: they describe the brand instead of telling someone what to do at 4pm on a Thursday when a banner is due. A good document is a set of decisions already made, written for non-designers.
Include tested colour pairings with contrast ratios. If your brand colours cannot make readable body text, say so in the document and give the approved alternative — otherwise someone will use the pale one on white and you will find out from a customer.
Guidelines are judged by how often they are opened, not how good they look when closed.
Twenty to forty pages for most businesses. Large organisations with many teams need more, but past that length the document usually becomes a reference nobody reads instead of a tool people use.
Yes, but a short one. Even a six-page version covering logo, colour, type and a few misuse examples keeps a business looking consistent once more than one person starts making things.
In a full identity project they normally are. In a logo-only project they usually are not, so check the proposal — guidelines are what turns a logo into something a team can actually run.
