What goes in a brand kit (and why your website needs one first)

What a brand kit is

A brand kit is the set of rules and files that make your business look and sound like itself everywhere it shows up. It's what lets your website, social posts, signage, invoices and email signature feel like they came from the same place, even when different people make them.

Without one, every new piece of marketing becomes a judgement call, and over time the brand drifts.

What should be in it

• Logo files: your primary logo, alternative versions such as stacked, horizontal and icon only, and versions for light and dark backgrounds, in SVG and PNG
• Clear space and minimum size rules, so your logo never gets cramped or unreadable
• Colour palette: primary and secondary colours with HEX, RGB and CMYK values, plus guidance on how much of each to use
• Typography: your fonts, where to get them, and how to use them for headings, body copy and small print
• Imagery style: the kind of photography and illustration that fits your brand, with examples of what to avoid
• Tone of voice: how you sound in writing, with a few do and don't examples
• Templates: social posts, presentations, email signatures and documents your team uses every week

Brand kit, style guide or brand guidelines?

You'll hear all three terms. In practice they overlap. A style guide or brand guidelines document usually explains the rules, while a brand kit is the practical bundle of files and templates that puts those rules to work. Small businesses usually need both in one place: a short guide and a folder of ready-to-use files.

Why your website needs it first

Your website is usually the first place people meet your brand properly. If you design the site before the brand is settled, you end up making brand decisions on the fly in the middle of a web project, and those decisions rarely hold together once you need a brochure or a sign.

With a brand kit in place, the web design moves faster, looks more considered, and sets up everything that comes after it. It also makes it much easier to use AI tools without ending up with a generic result, because you have clear rules to give them.

Consistency builds trust

People trust what feels familiar. When your Instagram, website and invoices all look like the same business, you come across as established and organised, even if you're a team of two. When they don't, customers notice, even if they can't say why.

Colour and accessibility

A good brand kit checks that your colours work for everyone. Text needs enough contrast against its background to be readable, including for people with low vision or colour blindness. It's much easier to choose accessible colour pairs at the brand stage than to fix them later. Our website accessibility guide covers why this matters.

Keep it practical

A brand kit isn't a 60 page document nobody reads. The best ones are short, visual and easy to find. Keep the files in a shared folder everyone can access, and make the most common templates ready to use.

Signs it's time to refresh your brand

• Your logo looks dated or doesn't work small, like on a phone or as a social profile image
• You've added services and the brand no longer reflects what you do
• Different team members have been creating their own versions of things
• You're targeting a more premium market than when you started
• You're expanding beyond your home city and want to look like a national business

A refresh doesn't always mean starting again. Often it's about tightening what you have and documenting it properly.

What it usually costs

A simple brand kit built around an existing logo can be a modest project, while a full identity with a new logo, strategy and templates is a bigger investment. Our branding service explains what's involved, and if a new website is next, the two can be planned together so nothing has to be redone. See our guide to website costs for that side.
