You have a logo. Then the printer stretches it to fit a banner, a new social media freelancer picks a different shade of blue, and the sales team builds proposals in whatever font their laptop offers. Within a year the brand looks like three different companies.
Brand guidelines stop that drift. This guide explains what a practical style guide contains, how to write rules that vendors actually follow, which specifications matter most, and how to keep the guide useful as your team and suppliers change.
Quick answer: Brand guidelines are a short reference that shows how to use your brand correctly. A practical guide covers logo versions and misuse rules, clear space and minimum size, colour codes in HEX, RGB, CMYK and Pantone, fonts and type hierarchy, photo and icon style, tone of voice and ready-made templates. Keep it short, specific and easy to find.
What brand guidelines are for, and who reads them
A brand guide is a working document, not a coffee-table book. Its readers are busy people who need one answer quickly.
- Designers and agencies: the rules for logos, colour, type and layout, so new work matches old work.
- Printers and signage vendors: colour codes, file formats and minimum sizes for physical output.
- Your sales and operations teams: templates for proposals, presentations, letterheads and email signatures.
- Developers: colour values, fonts and component styles for the website and apps.
- New hires, dealers and franchisees: a quick way to understand how the brand looks and sounds.
If a section does not help one of these readers make a decision, it can usually be cut.
The core sections of a brand style guide
- Brand basics: one paragraph on who you are, who you serve and the personality of the brand.
- Logo: approved versions, clear space, minimum size, placement and misuse examples.
- Colour: primary and secondary palettes with codes for every medium, plus approved text-and-background pairs.
- Typography: fonts for headings, body text and numbers, with sizes and weights, and fallback fonts for tools such as Google Docs and PowerPoint.
- Imagery: the kind of photographs and illustrations you use, and what to avoid.
- Icons and graphic elements: icon style, patterns and shapes, and how they are used.
- Tone of voice: how you write, with a few before-and-after examples.
- Templates and files: where to find the logo kit, templates and approved photos.
A small business can start with a focused guide of a dozen or so pages and add sections later, such as packaging, signage or vehicle branding, when the need appears.
Logo rules that prevent the most damage
Most brand damage happens to the logo, so this section deserves the clearest rules and the most examples.
- Clear space: the empty area around the logo. It is usually defined by a part of the logo itself, such as the height of one letter, so it scales with the logo.
- Minimum size: the smallest width at which the logo stays legible, given separately for print in millimetres and for screens in pixels.
- Approved versions: which version to use where, for example the horizontal logo in website headers and the icon for social media profile pictures.
- Backgrounds: which version goes on light, dark and photographic backgrounds.
- Misuse examples: show, do not just tell. Include images of the logo stretched, recoloured, rotated, outlined, with drop shadows or placed on a busy photo, each marked as incorrect.
Colour and typography: what to specify
Vague instructions such as 'use our blue' create the most inconsistency. Write down exact values for every medium where your brand appears.
| Element | What to specify | Why it matters |
|---|---|---|
| Primary colours | HEX, RGB, CMYK and Pantone values for each | Keeps screens, print and merchandise as close as possible |
| Secondary and neutral colours | Codes, plus where each may be used | Stops random colours creeping into posts and slides |
| Text and background pairs | Approved combinations with enough contrast | Keeps text readable; WCAG asks for a contrast ratio of at least 4.5:1 for normal body text |
| Heading and body fonts | Font names, weights and a size scale | Gives documents and screens a clear hierarchy |
| Fallback fonts | Substitutes for PowerPoint, Google Docs and email | Teams without the brand font still stay close to the look |
| Font licences | Who holds the licence and what it covers | Avoids using a paid font without the right licence |
If your brand uses Hindi or another Indian script on signage or packaging, specify a matching font for that script as well, chosen to sit comfortably next to your English font.
Templates and a shared asset library
Rules alone are not enough. People follow guidelines when the correct file is easier to find than the wrong one.
- One shared folder: logos in every format, colour swatches, fonts or font links, approved photos and icons.
- Templates for frequent documents: proposals, quotations and invoices, presentations, letterheads, visiting cards, email signatures and social media posts.
- Clear file names: for example brand-logo-horizontal-white.svg, so nobody has to guess.
- A one-page quick reference: the logo, colours and fonts on a single sheet that a vendor can read in a minute.
For invoices and quotations, design the template around the fields your accounts team actually needs, such as GSTIN, HSN or SAC codes and bank details, so the layout does not break when real data goes in. If your team builds many decks, a proper master template from our presentation design team keeps slides on brand without policing every file.
Keeping the guidelines alive
- Name one owner, usually someone in marketing or the founder's office, who approves new templates and answers questions.
- Put a version number and date on the cover, and keep older versions in an archive folder.
- Send the guide and the asset folder link to every new agency, printer and freelancer before they start work.
- Review real work every few months: recent posts, brochures and slides. Fix the templates where people keep going wrong.
- Update the guide when you add a product line, a sub-brand or a new channel, rather than letting each team improvise.
Guidelines are part of a wider identity system. If you are planning a full refresh rather than a rulebook for what you already have, our graphic design and brand identity work covers the logo suite, colour system and guidelines together.
How EthicsComputer can help
Our graphic design team builds identity systems that include a vector logo suite, colour codes for screen and print (HEX, RGB, CMYK and Pantone), typography rules and a brand guidelines document in PDF and Figma. If you are starting from scratch, begin with logo design; if your brand is set but your sales material is not, we can turn the guidelines into editable templates for your team. Source files and rights are handed over to you.
