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.
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.
