A good logo is one that works. That’s the whole test. Works where? Everywhere. Small, large, in colour, in black and white, on screen, in print, for five years and for twenty.
Here are the five principles that separate logos that stand the test of time from ones that date within three years — and why each one matters in practice.
1. Simple
The most recognisable logos in the world are simple. Nike’s swoosh. Apple’s apple. McDonald’s arches. You can draw most of them from memory, in the dark, after one glass of wine. That’s the point.
Simplicity isn’t laziness — it’s restraint. A simple logo is easier to reproduce across every application (print, embroidery, signage, digital), scales better at small sizes, and is more memorable than a complex illustration. If your logo requires more than five seconds to understand, it needs simplifying.
The impulse to add more is understandable. You want the logo to say something about your values, your heritage, your service. But a logo isn’t a brochure. It’s a mark. The more you load into it, the less it works as a mark.
The practical rule: if you removed one element, would the logo stop working? If the answer is no, remove it. Keep going until you can’t remove anything without breaking it. What’s left is your logo.
2. Memorable
A logo is doing its job if someone can recall it after one or two exposures. This usually comes from having one distinctive element — a unique shape, a surprising use of negative space, an unexpected twist on a letterform, an interesting relationship between two elements.
Memorable doesn’t mean flashy. It doesn’t mean complicated. It means there’s one specific thing about this mark that catches, that gives the eye somewhere to land, that makes it different from the other marks in the same space.
Think about the FedEx logo. On the surface it’s just a wordmark in two colours. But the arrow formed in the negative space between the E and the x is the thing you can’t unsee once you’ve noticed it. That’s a single clever element that makes the logo genuinely memorable. Not everyone sees it immediately. But everyone remembers it once they do.
You don’t need an elaborate hidden meaning. But you do need one thing that’s distinctively yours.
3. Versatile
A logo that only works on a white background at full colour on a screen isn’t really a logo — it’s a website graphic. Real logos have to work everywhere.
That means: in black on white. In white on black. In a single flat colour. Reversed out over a photograph. At 16x16 pixels as a browser favicon. At 3 metres wide as a sign on the side of a building. Embroidered on a jacket. Etched into a product.
Every one of these applications has different constraints. A logo that relies on subtle gradients to communicate something will fail when it needs to be printed in one-colour. A logo with thin, delicate letterforms will be unreadable at small sizes. A logo that only works horizontally won’t fit a square profile picture.
The test: print your logo at 16mm wide (about the size of a postage stamp). Can you read it? Can you identify it? If not, it needs simplifying.
4. Relevant
A logo should feel right for the business it represents — not as a literal illustration of what you do, but as a visual tone that matches your market, your personality, and your audience.
A children’s nursery and a corporate law firm will communicate very differently. Their logos should reflect that. Warm, rounded, playful versus sharp, structured, authoritative. These aren’t just aesthetic preferences — they’re signals that help potential clients quickly understand whether this business is for them.
Relevance doesn’t mean being obvious. A plumber doesn’t need a tap as a logo. A florist doesn’t need a flower. That kind of literalism is often lazy design. But it does mean understanding the visual language that resonates with your specific audience and deploying it deliberately.
The deeper layer: relevance is about your position in the market, not just your sector. A budget plumber and a premium plumber might both do plumbing — but their brands should communicate differently, because they’re talking to different clients with different expectations.
5. Timeless
The worst logos are the ones built around a design trend. Drop shadows were fashionable in the early 2000s. Glossy bevels were everywhere in 2007. Gradients came back in 2016. Badge logos were everywhere in 2018. “Clean and geometric” is probably being overused right now.
None of these date well. A logo built on a trend looks current for about two years, then starts to look dated, and by year five looks embarrassingly of-its-time.
A good logo avoids anything that feels fashionable right now, because fashionable things go out of fashion. Instead, it builds on classic design principles that hold up decade after decade: strong geometry, clear hierarchy, considered proportion, meaningful negative space. These aren’t exciting principles. They’re enduring ones.
The practical implication: if you’re showing your designer examples of logos and thinking “this is trendy and cool,” ask yourself whether you’d still feel the same way in ten years. You want a logo that looks like it was made by someone who knew what they were doing — not one that screams a particular year.
A note on breaking the rules
These five principles are not laws. They’re guidelines, and every great designer can show you examples of logos that break one of them and still work brilliantly.
But you earn the right to break a rule by understanding it first. A complex logo can work if it’s complex in a considered, deliberate way with a reason behind every element. A trendy logo can work if the brand genuinely needs to feel current rather than classic.
If your current logo fails one of these tests, it’s worth having a conversation about whether that’s costing you. Book a free 30-minute chat → or read more about what a brand identity project involves.
