Real-Estate Signs: The Curbside Glance
Yard signs and site boards are viewed from 3 to 10 meters — by pedestrians on the sidewalk and drivers slowing past. Nobody stops their car, gets out, and walks up to scan a 25 mm code; the code must work from the curb, which means it must be big. Real-estate codes compete with everything else on the sign — price, agent photo, phone number — so the code has to earn a large, uncluttered panel.
The 10:1 Rule of Thumb
At 5 m the rule suggests 500 mm, which is impractical on a standard yard sign. The practical compromise: 250–300 mm codes target pedestrians and slow traffic at 2–4 m, which is honestly where scans happen. Anyone viewing from farther away was never going to scan anyway. On large site hoardings viewed from across the street, scale up proportionally — hoardings have the space, so use it.
Recommended Size
Print at 300 × 300 mm (about 12 inches) on the sign's main panel or as a separate rider beneath it. Face the code toward the sidewalk at pedestrian eye height — not toward the road at driver height. One code per sign: multiple codes (agent profile, listing, mortgage calculator) paralyze the viewer and none of them gets scanned.
Substrate and Printing
Signs use aluminum composite, corrugated plastic (coroplast), or PVC board with UV flatbed or screen printing. UV-stable inks are mandatory — a sign that bakes in the sun for a months-long listing will fade an unprotected code into unscannability. Anything less than outdoor-rated materials is a false economy; the sign looks fine while the code silently dies.
Placement and Practical Tips
- Sidewalk-facing, at pedestrian eye height. The road-facing side is for the phone number in big type; the sidewalk side is where scans happen.
- Link to the live listing or a virtual tour, and keep it live until well after settlement. Dead links on "SOLD" signs are a brand embarrassment that outlives the listing.
- Reflective sheeting is great for night visibility but can interfere with scanning — test at night with an actual phone, not just in daylight.
- Keep the code's panel uncluttered: no "SOLD" rider overlapping it, no balloons tied over it, no fine print crowding the quiet zone.
- Use a short redirect URL per listing so codes stay small-modulated and links can be updated or retired centrally.
Common Mistakes
- A business-card-sized code on a yard sign — the classic failure, invisible beyond a meter.
- Letting the listing URL expire mid-campaign while the sign is still in the ground.
- Placing the code where the "SOLD" or "UNDER CONTRACT" rider will cover it.
- Encoding the full MLS URL with session parameters instead of a short redirect.
