How long should brand guidelines be?

There is no fixed length. A startup might need 10–15 pages, while an enterprise brand could require 50+. What matters is that every section is actionable and clear, not that the document is long.

How often should brand guidelines be updated?

At minimum, review your brand guidelines once a year. Update them whenever you rebrand, launch new products, expand to new markets, or notice recurring inconsistencies in how your brand is represented.

Brand Guidelines: What They Must Include to Be Truly Useful

Why Most Brand Guidelines End Up Gathering Dust

Here is a sobering statistic: according to Lucidpress, consistent brand presentation across all platforms can increase revenue by up to 23%. Yet many companies invest in brand guidelines that no one actually follows.

The reason? The document is either too vague, too rigid, or missing critical sections. A PDF with a logo and two hex codes is not a brand guide — it is a starting point at best.

Let us walk through what truly useful brand guidelines must include.

The Non-Negotiable Elements

Brand Mission, Vision, and Values

Before any visual element, your guidelines should state why your brand exists. This gives every designer, copywriter, and marketing partner the context they need to make on-brand decisions — even in situations the guide does not explicitly cover.

Keep it short. Three to five sentences for mission and vision. Three to six core values with a one-line explanation each.

Logo Usage Rules

This is the section most companies include, but few do well. Effective logo guidelines cover:

Primary logo and approved variations (horizontal, stacked, icon-only)
Minimum clear space around the logo (usually defined in relation to the logo itself)
Minimum size for print and screen
Incorrect usage examples — stretched, recolored, placed on busy backgrounds

Showing what not to do is just as important as showing what to do.

Color Palette

List your primary and secondary colors with values in HEX, RGB, CMYK, and Pantone. A common mistake is providing only HEX codes, which leaves your print partners guessing. Include guidance on color hierarchy — which color dominates, which is an accent, and which is reserved for backgrounds.

Typography

Specify your primary typeface for headings, a secondary typeface for body text, and a web-safe fallback. Include:

Font weights and styles to use
Minimum font sizes for body text (16px for web is the current standard)
Line-height and letter-spacing recommendations

Compare a brand that specifies “use Montserrat” with one that specifies “use Montserrat Semi-Bold at 32px for H2 headings with 1.3 line-height.” The second version actually gets implemented correctly.

The Often-Overlooked Sections

Tone of Voice

Your visual identity is only half the equation. A tone-of-voice section should define:

Personality traits (e.g., confident but not arrogant, warm but not casual)
Vocabulary preferences — words you use and words you avoid
Examples of on-brand vs. off-brand copy for common scenarios like emails, social posts, and error messages

Photography and Imagery Direction

Without this section, teams default to generic stock photos that dilute your brand. Define your preferred image style — lighting, composition, subjects, color grading — and provide a mood board with five to ten reference images.

Digital and Web-Specific Rules

Button styles, icon sets, hover states, spacing grids — these details matter enormously for web consistency. At Lueur Externe, when we build WordPress or PrestaShop sites, having clear digital brand specs saves weeks of back-and-forth and produces a far more polished result.

Co-Branding and Partner Usage

If partners, resellers, or affiliates ever display your brand, include a section on co-branding rules. Define logo placement hierarchy, required disclaimers, and approval workflows.

How to Keep Your Guidelines Alive

A 60-page PDF buried in a shared drive helps no one. Consider these approaches:

Host guidelines on a living URL that is always up to date
Include a changelog so teams know what has been updated
Assign an owner — someone responsible for enforcement and updates

Brands like Spotify and Mailchimp publish their guidelines online, making them searchable and easy to reference. You do not need their budget to follow the same principle.

Conclusion: Guidelines That Work Are Guidelines That Get Used

Brand guidelines are not a creative exercise — they are a business tool. When done right, they eliminate guesswork, speed up production, and protect the brand equity you have worked hard to build.

If your current guidelines are outdated, incomplete, or simply ignored, it might be time for a professional overhaul. The branding and web experts at Lueur Externe help businesses across industries create brand systems that are clear, comprehensive, and built for real-world use.
