Brand guidelines go by many names: brand standards, brand manual, style guide, brand book. The terminology varies by agency. The purpose is the same: a document that defines exactly how your brand should look and behave across every context.
Without guidelines, every designer who touches your brand makes different decisions. The blue on your business card becomes a slightly different blue on your website. The logo appears at different sizes on different documents. The typography choices depend on whoever is working that day. Over time, the brand loses coherence — not through any single catastrophic decision, but through accumulated inconsistency.
Brand guidelines prevent this. They codify every decision once, so every future application of the brand starts from the same foundation. This article explains what a complete set of brand guidelines contains and why each section matters.
For the broader context on brand identity, see what is brand identity design and logo design vs brand identity.
Section 1: Logo Usage
The logo section covers every approved version of the mark and how each should be used.
Primary logo. The main version of the logo — the one that appears in most contexts. Shown at a minimum size with clear space requirements defined (the minimum whitespace around the logo).
Logo variations. Most logos have multiple versions for different backgrounds:
- Dark version (for light backgrounds)
- Light version (for dark backgrounds)
- Monochrome (black only, for single-colour applications)
- Reversed (white, for dark backgrounds where colour printing isn't available)
- Horizontal and vertical arrangements if applicable
Incorrect usage. A section showing explicitly what not to do with the logo: don't stretch it, don't change the colours, don't add effects, don't place it on a background that makes it unreadable. This is often where the most brand damage occurs — not from malicious changes but from well-intentioned "quick fixes."
Clear space. The minimum whitespace required around the logo in any application. Usually expressed as a proportion of the logo's height or width (e.g., "the minimum clear space is equal to the height of the logo's letterforms").
Minimum size. The smallest size at which the logo can appear and remain legible. Usually defined in both millimetres (for print) and pixels (for digital). Below this size, a simplified or icon-only version may be used.
Our brand guidelines service produces all of these specifications as part of the standard deliverable.
Section 2: Colour System
The colour section defines every approved brand colour with precise values for every medium.
Primary palette. The core brand colours that carry most of the visual identity load. Usually 1–3 colours.
Secondary palette. Supporting colours used for accent, secondary communication, and variety within brand-approved ranges.
Colour specifications. For each colour, four values are required:
- Hex code (web and digital)
- RGB values (screen applications)
- CMYK values (offset print)
- Pantone number (spot colour, embroidery, standardised reproduction)
See choosing brand colours for how these palettes are built and why each value matters.
Colour usage rules. Which colours can appear together, which combinations are prohibited, what percentage coverage each colour should have in typical layouts.
Colour on backgrounds. Specifications for how brand colours appear on white, black, and coloured backgrounds — including minimum contrast ratios for accessibility.
Section 3: Typography
The typography section defines the typefaces used in brand communications and the hierarchy for how they're applied.
Primary typeface. The main font used for headings, large text, and primary brand communication. Includes the approved weights (Regular, Medium, Bold) and their appropriate use cases.
Secondary typeface. The supporting font for body text, captions, and secondary information. Usually a more neutral choice that complements the primary typeface without competing with it.
System typeface fallback. For contexts where brand fonts aren't available (email, some software, web before font loading), the approved substitute (usually a system font like Georgia, Arial, or -apple-system).
Type scale. The approved sizes for each level of the hierarchy: H1, H2, H3, body, caption, label. Often includes line-height and letter-spacing values for each level.
Type treatment. Whether the brand uses sentence case, title case, or all-caps for specific contexts. Whether body text is justified or left-aligned. These seemingly minor decisions accumulate to create a distinct visual character.
Section 4: Photography and Imagery
Photography style. The visual tone of images used in brand communications — candid vs posed, light and airy vs moody and dark, product-forward vs lifestyle, etc. Usually illustrated with approved and unapproved examples.
Image composition guidelines. Whether images are full-bleed or contained, how logos interact with photography, whether text overlays photography directly or uses a panel.
Illustration style (if applicable). Brands that use custom illustration need specifications for line weight, colour palette usage, and stylistic range.
Icon system (if applicable). Icon design principles, approved icon set, sizing grid.
Section 5: Voice and Tone
Visual guidelines without voice guidelines produce brands that look consistent but communicate inconsistently. A complete brand guidelines document includes:
Brand personality. The character attributes that define how the brand communicates — professional but approachable, bold and direct, precise and calm.
Writing principles. Rules for how the brand writes: sentence length, vocabulary level, use of technical language, use of humor.
Tone by context. How the voice shifts across different situations: social media posts feel different from legal disclaimers, but both should be recognisably the same brand.
Terminology. Approved names for products, services, and brand elements. Words to avoid.
Section 6: Layout and Design System
Grid system. The underlying grid used for layouts — column count, gutter width, margin specifications.
Spacing system. The approved spacing increments for padding, margins, and element separation.
Component examples. Business card layout, letterhead, social media templates, email signature, presentation cover page.
Digital applications. Website header, app icon, social media profile image specs.
How Brand Guidelines Are Used in Practice
Brand guidelines are a reference document, not a decorative one. They should be:
- Distributed to every designer, developer, and agency working on brand materials
- Included in every design brief
- Referenced when approving or rejecting work
- Updated when the brand evolves (and version-controlled so old versions are archived)
The most common failure mode is creating guidelines and filing them. A document that no one references does nothing. The guidelines work when they become the default starting point for every brand touchpoint.
Do You Need a Full Brand Guidelines Document?
If you're a founder with a logo and a color palette, you don't necessarily need a 60-page brand book immediately. A minimal set of guidelines covers:
- Logo variations and clear space
- Colour values in all four formats
- Approved typefaces and basic hierarchy
- One or two examples of correct usage
As the business grows and more people touch the brand, the guidelines grow with it. The brand guidelines service at Evoke Studio produces the scope that matches your current stage — not an overwhelming document that won't be used, but the specific decisions that need to be documented now.
