Brand guidelines

Brand guidelines are the document that says how your logo, colours, type and tone are used. They exist so that work made by different people still looks like one business.

Also called brand book, style guide, brand manual, visual identity guidelines

Brand guidelines are a document that sets out how your business is allowed to look and sound. Which logo file to use and how much space it needs. The exact colours, in the values a printer and a screen each require. The typefaces. The kind of photography. Sometimes the tone of the writing. It exists so that work made by different people at different times still reads as one business.

In short

  • It is the rulebook for how your business looks and sounds.
  • Its job is consistency across people who never speak to each other.
  • Short and read beats long and ignored.
  • Recognition comes from repetition, so the rules only work if they hold.

The problem it solves

A business rarely produces all its own materials. A printer makes the flyers. A signage supplier makes the tarpaulin. A relative built the website in 2019. Somebody’s cousin runs the Facebook page. A supplier puts your logo in their catalogue.

None of these people talk to each other, and each works from whatever they were sent. Without a shared reference they improvise, reasonably, and the result is five versions of your business that a customer sees in one week without ever consciously registering that they do not match.

That is what the document prevents. It is less a creative artefact than a coordination device.

What actually belongs in it

Four items do most of the work, and a document containing only these four is already worth more than most of what gets produced.

  • The logo, in real files. Vector for anything printed or scaled, and ordinary image files for everyday use. Plus a version that works on a dark background, which is the one always missing.
  • Colour values, for both worlds. The screen values for anything digital, and the print values for anything on paper or vinyl. Without both, a printer guesses.
  • Typefaces, with a fallback. The font you use, plus what to use when it is unavailable, which happens constantly.
  • A short list of do not. Do not stretch it, do not recolour it, do not put it on a busy photograph, do not retype the name in a different font.

Everything beyond those is worth having and none of it prevents as much daily damage as those four.

Why the colour question keeps coming up

Screens produce colour with light and printing produces it with ink, and that difference causes more confusion than anything else in these documents. Printing produces it with ink. The two work differently enough that a value which looks right on a monitor cannot simply be handed to a printer, and a colour picked from a photograph of your own signage is already two conversions away from the original.

Guidelines fix the part that can be fixed. Each colour is stated once, in each system, as the source of truth, so every supplier starts from the same instruction rather than from a guess. Your tarpaulins then match each other and come as close to the screen version as ink allows.

They will not match it exactly, and no document changes that. Some bright screen colours have no ink equivalent. Where an exact match genuinely matters, on a shopfront or packaging, a spot colour is specified alongside the others, which is a printing instruction rather than a recipe.

The version a small business can write today

Waiting for a formal identity project is how most businesses end up with nothing, so start with a folder. Put the logo files in it, in every format you have. Write a page listing the colour values, the fonts, and five things you do not want done. Send that folder to anybody who makes anything with your name on it, before they start rather than after they finish.

That is not a brand book and it will prevent most of the inconsistency. The deeper question of what the identity should be, and whether the current one is serving you, is a graphic design conversation and a separate piece of work.

Consistency is the whole mechanism

The reason any of this matters is not neatness.

People recognise a business through repetition. The same colour, the same mark and the same voice, encountered enough times, become familiar, and familiarity is most of what brand awareness actually consists of. A business that changes its look every year restarts that process every year and never accumulates anything.

Guidelines are how a small business gets that consistency without anybody policing it full time. The document does the remembering.

Where they meet the website

The website is usually where guidelines are broken first and noticed last.

Colours drift when somebody picks a shade from a screenshot rather than a value. Fonts get substituted when a licence does not cover the web. Logos get uploaded at the wrong size and rescaled by the browser into something soft. None of this is visible to whoever made the change, and all of it is visible to somebody comparing the site against the shopfront.

Handing the folder to whoever builds or maintains the website at the start is a five minute step that prevents a long argument later.

When to change them

Guidelines that never change are doing their job. Guidelines changed on a whim are undoing it.

The reasonable triggers are structural: the business is renamed, the services change enough that the old description misleads, or the identity was genuinely made badly and is holding you back. Boredom is not one of them, and it is by far the most common reason offered. You look at your own logo far more often than any customer does, which makes you the worst available judge of whether it has gone stale.

Questions we get

More about brand guidelines

Does a small business need brand guidelines?

If more than one person ever makes something with your name on it, yes. The moment a printer, a signage supplier and whoever runs your Facebook page are all working separately, the guidelines are what stops three versions of your business appearing around town.

How long should a brand guideline be?

Short enough that somebody reads it. A few pages covering the logo, the colours, the type and what to avoid will do more than forty pages nobody opens. Large brands need the long version because they have large teams, which is not the situation you are in.

What must brand guidelines contain?

The logo files in the formats people actually need, the exact colour values for both screen and print, the typefaces with a fallback, and a short list of things not to do. Everything else is useful. Those four are the ones whose absence causes real problems.

Which colour values does a guideline need to list?

One for screens and one for print, because the two make colour differently and a value from one is meaningless to the other. Add a spot colour where an exact match matters, such as a shopfront or packaging. Listing only the screen value is the most common omission and the one printers ask about.

Can I write brand guidelines myself?

The practical half, yes. Collect the files, write down the colour values, name the fonts and list what you do not want done. That covers most of the daily damage. Deciding what the identity should be in the first place is the part worth having a designer for.

How often should brand guidelines change?

Update them when the document has stopped describing the business, which usually means a new name, a new service line, or a supplier need it does not cover. A guideline that has not changed in three years is generally doing its job rather than falling behind.

What if a supplier ignores the guidelines?

Send the document before the work starts rather than after. Most breaches are not defiance, they are somebody who was never given the files and used whatever they could find online, which is usually an old logo pulled off a screenshot.
