Why this matters
A sign nobody can read at walking speed is decoration, not marketing. Founders pick the font that matches their mood and the palette that matches their logo — then wonder why the sign changes nothing. You paid for the message; make sure it physically reaches eyeballs.
What "done" looks like
- The headline is legible from where customers actually stand
- Every sign uses a strong light-dark pair — no mid-tone on mid-tone
- One message per sign, set plain and bold, as the biggest element
- A blurry phone photo from across the room still communicates the point
How to do it
- Measure the real viewing distance for each sign location — door, aisle, window.
- Size letters to the sign-industry rule: about 1 inch of letter height per 10 feet of viewing distance — a 20-foot sightline needs ~2-inch letters.
- Pick a high-contrast pair — black on white or yellow, white on dark. Kill gray-on-beige.
- Use a plain bold sans-serif for headlines; save decorative fonts for small accents.
- Cut the headline to 3–7 words, then squint at a photo taken from real distance — if the message dies, resize.
Common mistakes
- Choosing a font for personality that becomes unreadable beyond 10 feet
- Low-contrast "tasteful" palettes that vanish under store lighting
- Cramming three offers onto one sign so none registers
Real-world examples
- Letter-height visibility charts published across the sign industry (Signs.com, Signazon, and most commercial printers) use about 1 inch of height per 10 feet of distance as the readability baseline.
- Highway signage worldwide uses plain, high-contrast sans-serif type — legibility research, not aesthetics. When reading speed matters, every mature system converges on big and plain.
From a founder's point of view
A sign is not a place to express taste; it is a machine for moving one message into a stranger's head in two seconds. Decoration that slows that transfer is a cost, however pretty it looks up close.
Rule of thumb
If the headline doesn't survive a squinted photo from where customers stand, the sign fails — no matter how good it looks from two feet away.
