We see the same seven mistakes on customer-supplied designs every single week. None of them are about taste — they're physics and psychology, and each has a simple rule that fixes it. Steal these.

1. Letters too small for the distance

The rule: 1" of letter height per 10 feet of comfortable reading distance — double it for traffic moving past. The #1 mistake by miles: designs approved on a 27" monitor at arm's length, then read from a moving car at 200 feet. Our Design Studio shows true physical sizes as you type, specifically to kill this mistake.

2. Thin, script, or trendy fonts

The rule: bold, simple letterforms at distance; save personality fonts for up-close materials. Hairline fonts vanish in glare, and that gorgeous script becomes calligraphy soup at 60 feet. If squinting is required, the font failed.

3. Low contrast

The rule: dark-on-light or light-on-dark — never mid-on-mid. Gray on white, gold on beige, red on black (the classic offender — red reads as dark at distance) all die outdoors. The old sign painter's checklist still rules: black/white, black/yellow, white/blue, white/red. Boring wins from the road.

4. Trying to say everything

The rule: a sign earns 3 seconds and 7 words. Name, what you do, one contact. The full service list, three phone numbers, the fax (!), and the founding year all cost legibility — every added element shrinks everything else. Signs create the customer; brochures close them.

👁️ The squint test: stand back from your design (or shrink it to thumbnail size) and squint. Whatever you can still read is what drivers will actually see. If it's not your name and number, redesign.

5. No breathing room

The rule: empty space is not wasted space — it's what makes the message findable. Edge-to-edge designs read as noise. Pro layouts leave 10–15% margin minimum and let one element dominate.

6. Low-resolution logos

The rule: large format needs vector art. A logo grabbed from your website is 200 pixels wide; printed at 4 feet it's a blur mosaic. If all you have is a JPG, the Design Studio's free tracer converts it to crisp vector automatically — or our designers rebuild it properly.

7. Designing for the wrong lighting

The rule: know when your sign works. West-facing signs disappear in afternoon glare without high contrast; unlit signs go dark at 6 p.m. in December; interior-lit windows kill perforated film effects at night. Where the sun hits also decides materials — see the desert-proof guide.

The two-minute fix

Take your current design and ask: Can it pass the squint test? Is anything under the letter-height rule? More than 7 words? Fixing just those three moves puts you ahead of half the signs on any street in America. Or skip the class and let our designers make it right — design help comes with the quote.
