Start with the business, not the drawing: write a brief with the audience, competitors and where the logo will be seen. Generate many rough ideas, narrow to two or three routes, design in black and white, test at small sizes, score the routes against the brief, then search trademarks and produce clean files.

Wordmarks (the name as the logo, like Coca-Cola), lettermarks (initials, like IBM), pictorial and abstract symbols (Apple, Nike), combination marks (symbol plus name), emblems (everything inside a badge) and mascots (characters like the Michelin Man). The right type depends on the name, where the logo appears and the budget.

A good logo is distinctive, simple without being generic, legible at small sizes, works in one colour, fits the brand’s strategy and is ownable as a trademark. It does not need to explain the business. Consistent use over time is what makes a logo famous.

Typical 2026 ranges in the US, UK and Europe: $0–100 to do it yourself, $500–8,000 with a freelancer, $8,000–50,000 with an independent studio and $50,000 or more with a branding agency. Most early-stage startups need only a well-made wordmark and a small-size icon.

Agree weighted criteria before seeing any design, review options in black and white at the same size, score them independently, and test with real customers for recognition rather than preference. Reject any option that fails at 16 pixels, in one colour, or in a trademark search.

No. The golden ratio is a useful way to pick related proportions, but research finds no reliable preference for it, and many famous “golden ratio” logo overlays were drawn after the fact. Judge a logo by how it looks and works at real sizes.

You should search for conflicting trademarks before finalising a logo and register it in the countries where you trade. Also get a written copyright assignment from the designer — paying for a logo does not automatically mean you own it. Laws vary by country, so consult a trademark attorney.

Founders making or choosing a first logo, graphic and brand designers who want a stronger process, marketers planning a rebrand, and students or anyone curious about famous logos. The opening pages suggest a reading path for each.

More than 60 real logos and 19 true stories, including Bass’s red triangle (UK trademark No. 1), the Coca-Cola script, the FedEx arrow, the $35 Nike Swoosh, Milton Glaser’s I ♥ NY, Starbucks, Instagram, Gap’s reversed redesign, Tropicana and London 2012.

The content is the same. The Light edition has paper pages and is made for printing. The Dark edition is made for reading on a screen. You can ask for either one or both.
