Brand Book: What It Is, What Goes In It, and When You Need One
The difference between a logo book, guidelines and a full brand book. Which sections are mandatory, how vendors use it, and why brands drift without one.
Brand books usually get commissioned twice. The first time because serious companies are supposed to have one, and the file goes into a folder. The second time because a supplier used the wrong blue and there was nothing to point at. The difference is that the second version gets written around real working situations rather than for an investor deck. Below: how a logo book differs from guidelines and a full brand book, which sections genuinely matter, when it is too early to commission one, and how many pages is enough.

people on the brand — the payback point
Logo book, guidelines and brand book are three different things
On studio price lists the phrase "brand book" covers anything from one page with a logo to a hundred-page volume. Agree on terminology before you start comparing quotes.
| Document | What it covers | Length | Who needs it |
|---|---|---|---|
| Logo book | The mark only: versions, sizes, clear space, prohibitions | 4–8 pages | A business that has just had a logo made |
| Guidelines | The whole visual system: colour, type, graphics, applications | 20–30 pages | Most companies — this is the working minimum |
| Brand book | The system plus strategy: positioning, values, tone of voice | 50+ pages | Chains, franchises, multi-team organisations |
The position we defend on projects: most small companies need guidelines, not a brand book. Strategic chapters look persuasive in a PDF, but daily decisions get made from the section on how to lay out a banner, not from the section on brand values.
The sections without which the document does not work
One test settles it: can an outsider produce a post, a deck and a banner using only this file? If they have to message you at any point, a section is missing.
The mandatory minimum
- Logo versions and the rule for choosing between them
- Minimum size and clear space expressed in modules, not millimetres
- Palette with HEX, RGB, CMYK and approved background–text pairings
- Typefaces, a size scale, and a fallback for unlicensed environments
- Rules for placing the logo over photography and coloured panels
- A "never do this" page built from real mistakes
- Ready templates: cover, deck, avatar, banner
When it is needed and when it is a premature expense
The document pays for itself the moment a second person starts working on the brand. Before that, every rule lives in the founder’s head and the file only repeats what everyone already knows.
- Time to write it. You now have a supplier producing layouts without you — every "make it our blue" comment costs an hour of email.
- Time to write it. You opened a second location or launched a franchise; without written rules the signage diverges within one season.
- Time to write it. You print regularly — the print shop should receive CMYK and Pantone values from a file rather than guessing.
- Too early. The company is six months old, positioning is still shifting, one person makes every layout. Guidelines here document something that expires next quarter.
- Too early. The identity itself is incomplete, so there is nothing to describe. Build the identity first, then the rules for using it.
Guidelines are not a document about beauty. They are an instruction set that lets a stranger do the work correctly without you in the room.
How the file is actually used
- 1
They open it at one page
Nobody reads guidelines front to back. That is why a real contents page and bookmarks matter — a designer is hunting for one specific thing: a colour value, a minimum size, the heading typeface.
- 2
They copy values out
Colours must be selectable text, not a screenshot of a palette. It sounds petty until you receive the tenth layout in a colour someone eyedropped out of your PDF.
- 3
They take the source files
The document should ship with a folder of logos, fonts and templates. Guidelines without sources force a supplier to redraw the mark — which is exactly how a brand ends up with two versions of its own logo.
- 4
They settle disputes with it
When client and supplier disagree about a layout, the file acts as referee. That is its core economic function: cutting the number of arguments that come down to taste.
Format, length and cost
Documenting existing rules into a 20–30 page set of guidelines costs $250–800 when the identity already exists. A full brand book with strategic chapters starts around $1,500. The variable is not page design — it is how many application scenarios get described.
- 1Make it shorter than you want to. Twenty-five pages that get read beat 120 pages opened once a year.
- 2Keep it editable. Identities change in pieces: a colour is added for dark mode, a new application format appears. If you only received a flat PDF with no source, every update is a fresh invoice.
- 3Distribute it with the file folder and a version date on the cover. Half of all drift happens because three suppliers are working from three different editions of the same document.
Guidelines have to live alongside the brand: when the logo or palette changes, the document is updated the same week, otherwise it quietly becomes a source of misinformation. On recognising that the whole system has aged out, see our guide to the signs you need a rebrand; on preparing the mark itself for these rules, see the logo design process.
Frequently asked questions about brand books
What is the difference between a brand book and brand guidelines?
Guidelines describe the visual system — logo, colours, typefaces, graphics, applications — typically across 20–30 pages. A brand book adds the strategic layer: positioning, values, brand character and tone of voice, and usually starts at 50 pages. Most small companies only need guidelines, because day-to-day decisions are made from visual rules.
How many pages should a brand book be?
As many as there are genuinely documented application scenarios, not "the longer the more serious". Working guidelines for a small business fit in 20–30 pages; a multi-location chain needs 40–60. A hundred-page document almost always means half the length is title spreads and philosophy nobody opens.
What does a brand book cost?
Turning an existing identity into a set of guidelines costs roughly $250–800, since the work is documentation rather than design. A full brand book with strategic chapters starts around $1,500. If the identity does not exist yet, those figures sit on top of the cost of creating it rather than replacing it.
Can I write brand guidelines myself?
Yes, if you have the source files and the discipline to finish. A minimum version is a few pages with logo variants, colour codes, typeface names and examples of what is not allowed. That already beats having no rules, though a designer will add things you would not think of: behaviour over photography, optical sizing, and how the palette holds up in dark mode.
How often should guidelines be updated?
By event rather than by calendar: the logo changed, a colour was added, a new application format appeared. A practical rule is to review the document once a year and update it immediately after any change to the identity. Outdated guidelines are worse than none, because suppliers keep working from rules that are no longer true.
In short
- A logo book covers the mark, guidelines cover the visual system, a brand book adds strategy. Most companies need guidelines.
- The document pays off as soon as a second person starts producing layouts without you.
- Mandatory minimum: logo versions, clear space, palette with codes, typefaces, photo rules and a prohibitions page.
- Keep the file editable and ship it with a source folder, or every update becomes a separate invoice.
