Most people judge a logo the way they'd judge a piece of art — do I like looking at it. That's a reasonable starting point, but it misses most of what actually makes a logo useful to a business.
A logo has to survive being small
A logo rarely gets seen at the size it was designed at. It ends up as a tiny circle on a social media profile, a favicon in a browser tab, a stamp on an invoice. If the detail collapses into a blur at 32 pixels, the logo has a real, practical problem — not just a stylistic one.
It has to work without color
Printed in black and white on an invoice, stamped on a package, faxed (yes, this still happens) — a logo that depends entirely on a gradient or a specific color combination to be readable will eventually show up somewhere that color doesn't reach.
It should say something true about the business
Symbols and shapes carry meaning whether intended or not. A logo built around sharp, angular lines reads differently than one built around soft, rounded forms — and that read should roughly match how the business wants to be perceived, whether that's precise and technical or warm and approachable.
A few practical checks
- Does it still look recognizable shrunk down to icon size?
- Does it hold up in plain black on white?
- Does it avoid relying on fine detail or thin lines that disappear when printed?
- Is it distinct enough that it wouldn't get confused with a competitor's mark?
Consistency matters more than novelty
A logo that stays the same across a website, packaging, social media and signage builds recognition over time. Constantly refreshing it to "keep things interesting" usually costs more in lost recognition than it gains in novelty.
A logo doesn't have to be complicated to be good — some of the most recognizable marks in the world are a handful of simple shapes. What makes them work is that every one of those shapes was a deliberate decision, not a leftover one.
