Brands express themselves in colors, typeface fonts, photo imagery, voice, and they have a "mood" and a set of characteristics that reflect their personality. Brand guides help to centralize all this information and make it "turnkey-simple" for your company to reproduce and speak for your brand in a way that delivers a consistent experience to your customers and prospects. If you are looking for Brand Guide inspiration, grab a cup of coffee and check out these graphically inviting links to brand guides of every kind.

Brand Guides ultimately communicate to your prospects and customers about what is important to you. This Manifesto below, by Momu Homes in Perth, Australia, is a creative way of telling consumers what their brand is about. I don't know if it's in their brand guide, but it says alot about what is important to them. They've figured out a fun way to tell customers and prospects how the brand is expressed through employees. Part of having a brand guide is knowing how to articulate what it means internally to your employees too.
I won't mention names, but we have brand guides that approach 80-100 pages for large Builder brands (and yes, our team reads them).
