How to Design a Billboard People Can Read in Five Seconds
In short: a good billboard can be understood in about five seconds. That means one idea, a short headline of around seven words, a large logo, strong contrast and a single simple action. Everything else is noise.
Why five seconds?
Most people see an outdoor advert while they are moving – driving, cycling, walking or on a bus. They glance at it rather than read it. If the message is not clear at a glance, it is missed. Designing for a few seconds of attention is the single most important rule of outdoor advertising.
The seven rules of billboard design
- One message only. Decide the one thing you want people to remember. Cut everything else.
- Around seven words or fewer. Short headlines are read and remembered; long ones are skipped.
- Big, bold type. Use a simple, heavy font. Avoid thin, script or condensed fonts that blur at a distance.
- Strong contrast. Dark text on a light background, or light on dark. Avoid colour combinations that merge, such as red on green.
- A large, clear logo. People should know who the advert is without searching for it.
- One striking image. A single bold picture works better than a collage.
- One simple action. A brand name to search, a short web address or a well-known location. On roadside sites, avoid long phone numbers – nobody can note them down while driving.
Adapt the design to the format
| Format | Viewing | Design tip |
|---|---|---|
| 48-sheet roadside billboard | a moving car, at a distance | Fewest words, biggest type |
| 6-sheet bus shelter | Up close, at eye level | Room for a little detail and a QR code |
| Digital LED screen | A few seconds per slot | One frame, one message; check motion rules |
| Bus advertising | Moving, the side or rear | Brand and one line, very large |
A quick test before you print
- The squint test: shrink the design to the size of a stamp on your screen. Can you still read the headline and see the logo?
- The five-second test: show the design to someone for five seconds, then ask what it was for and who it was .
- The distance test: print it on A4, put it on a wall and step back several metres.
Common mistakes to avoid
- Putting a whole leaflet's worth of text on a poster.
- Using a small logo in the corner.
- Low-contrast colours that disappear in grey weather.
- Several offers on one advert.
- Important content too close to the edges, the frame may cover it.
Frequently asked questions
Should I include a QR code on a billboard?
On bus shelters and pedestrian panels, yes – people stand close enough to scan it. On roadside billboards seen a car, a short web address or brand name is more useful.
Can you design the artwork for me?
Yes. Inteli Media UK offers artwork design sized correctly for each site and format.
