Logo Design

Logo Design — questions and answers

What makes a logo work in just one colour?

A logo that works in one colour relies on shape and proportion rather than colour contrast to remain recognisable. This matters because logos appear in contexts where full colour is unavailable: embossed on leather, etched on glass, stamped on receipts, or reproduced in newsprint. Designers test this by converting the logo to solid black and checking whether all elements remain distinct and legible.

Why are logos delivered as vector files rather than image files?

Vector files store logos as mathematical paths rather than pixels, allowing them to scale infinitely without blurring or becoming jagged. A logo might appear on a website at 200 pixels wide and on a billboard at six metres tall; the same vector file serves both. Common vector formats include AI, EPS and SVG, while raster formats like PNG or JPG are exported from vectors for specific uses.

Should a logo include a tagline or sit alone?

This depends on whether the name alone conveys enough meaning. New or abstract names often pair with a tagline initially to clarify what the organisation does, then drop it once recognition builds. Established names typically stand alone. Technically, taglines are often treated as separate elements with their own spacing rules, allowing the logo to appear with or without them depending on context.

What's a logomark versus a wordmark, and when does each make sense?

A logomark is a symbol without words; a wordmark is styled lettering of the name itself. Logomarks suit organisations with short, abstract or widely recognised names, but require more repetition to build meaning. Wordmarks immediately communicate the name, which helps lesser-known entities. Many identities combine both, using the full version formally and the mark alone where space is tight or recognition is already established.

How much detail can a logo contain before it stops working at small sizes?

This depends on the smallest size the logo will appear at in practice. Fine lines thinner than 0.5 points often vanish in print or low-resolution screens. Intricate details that look clear at 50mm wide become illegible at 15mm. Designers test this by viewing the logo at its minimum intended size, checking whether all elements remain distinct and whether negative space holds its shape without filling in.

Can a logo be changed later, or does it need to stay fixed forever?

Logos can evolve, but changes carry risk. Minor refinements—adjusting proportions, simplifying details, updating typefaces—often go unnoticed while improving performance. Major changes risk losing accumulated recognition. The decision depends on whether the existing logo still functions or whether shifts in the organisation, market or reproduction technology have made it inadequate. Rebrands typically happen every ten to twenty years, though some marks remain unchanged for decades.
