Sightlines, Approach Angles, and Intersection Heuristics
Most storefront traffic does not come straight on from the center of the block. People approach from different directions and heights, and each group sees something different as they move.
Common approach patterns include:
- Along-the-block pedestrians walking with the flow on each side of the street
- Corner crosswalk users coming from the intersection on both sides
- People stepping out of buses, cabs, or ride-shares near the curb
Along-the-block walkers see your storefront at a shallow angle for a while, then more head-on near your door. Crosswalk users often first see only the edge of your space as they step off the curb. People exiting vehicles may have their view blocked by the car roof, nearby traffic, or other parked cars.
A few simple intersection heuristics help:
- Aim your most important signs within about 30 to 45 degrees of the most common approach angles on each side.
- Make sure at least one edge of a sign is visible from each crosswalk corner.
- Keep key text and logos out of dead zones behind columns, deep recesses, or where door swings always block the view.
Technical sightline checks are simple but powerful. We suggest:
- Put small tape marks on the sidewalk at 50, 75, and 100 feet from your door in both directions and toward each corner.
- Stand at each mark at eye level and take photos facing your storefront, day and night.
- Note when parts of your sign disappear behind cars, poles, trees, scaffolding posts, or bus shelters.
Repeat this once after the time change when evenings get darker earlier. You may see that a sign which feels bright at noon is almost lost at 5 p.m. without proper lighting.
