Wall Advertising
What Size Wall Is Good for Outdoor Advertising?

Short answer
The number that matters is the clear, flat, open rectangle on the wall — not the wall's total size. Bigger usually reads better and is worth more, but a smaller wall close to slow traffic can beat a large wall set far back.
Measure the clear area
Find the biggest rectangle with no windows, doors, vents, downspouts, pipes, or other signs. Write down the width and height. That rectangle is what an advertiser is actually buying.
Distance changes everything
The farther away drivers are, the bigger your letters need to be, which means less fits on the wall. A wall 40 feet from the road can show more detail than one 300 feet back. When a wall is far away, the ad just becomes a logo and a few words.
Rough guidance
- **Small clear area:** can work when traffic is close and slow, for a simple logo and short phrase.
- **Medium:** the common sweet spot on neighborhood business streets.
- **Large:** best for fast roads or long-distance viewing, and worth the most to advertisers.
We avoid giving hard minimum sizes, since the same size wall can work very differently depending on distance, speed, and view.
Also write down
- How high off the ground the clear area starts
- The wall material — brick, block, concrete, stucco, or metal
- Anything blocking the view from the road
- Which direction it faces
