Outdoor Creative That Works

People see your ad for a few seconds at 55 mph. Here are the rules that make outdoor creative land.

The core rules

  1. Seven words or fewer. One idea per board. If it needs a paragraph, it needs another medium.
  2. One big image. A single, bold visual beats a collage every time.
  3. Brand it big. Logo large and immediately visible — usually not tucked in a corner.
  4. Contrast is everything. Dark on light or light on dark; avoid similar hues (red on green, blue on purple).
  5. Simple, heavy type. Bold sans-serifs, no scripts, generous letter spacing. Upper/lower case reads faster than ALL CAPS.
  6. One clear action. An exit, a short URL, a memorable phone number, or a QR code where people are stationary.
  7. Test small. Print your design at 2 inches wide and view it from 10 feet — that approximates highway viewing.

Type size & legibility

Viewing distanceMinimum letter height
100 ft~4 in
200 ft~8 in
300 ft~12 in
500 ft~20 in
1,000 ft~40 in
Common rule of thumb: about 1 inch of letter height per 25 feet of viewing distance for good readability.

Design for the context

  • Highways — 3–5 seconds of attention; ultra-simple, directional.
  • Urban & street level — closer viewers allow a bit more detail; QR codes can work.
  • Transit interiors & place-based — long dwell; you can tell a story, add offers and codes.
  • Airports — premium, aspirational; business travelers in a waiting mindset.
  • Digital — use dayparting and data triggers; on roadside boards keep each frame static and self-contained.

DOOH creative tips

  • Make the first frame work alone — viewers may only catch one.
  • Use contextual messaging: time of day, weather, local landmarks, live countdowns.
  • Build multiple versions and rotate to avoid wear-out.
  • Check brightness: very white backgrounds glare at night; mid-tones read better.

File & production specs

  • Static: vendors usually want print-ready PDF or TIFF at scale (often 1"=1' at 300 dpi or similar), CMYK, with bleed.
  • Digital: JPG/PNG (RGB) at exact pixel dimensions; MP4 for video-capable screens; check max file sizes.
  • Approvals: most vendors and transit authorities review copy — allow time for edits.
Always request the vendor's spec sheet before design begins, and design to the live area, not the full trim.

Common mistakes

  • Too many words or a long URL
  • Tiny logo, or a logo that only appears in the corner
  • Low contrast or busy photography
  • Multiple calls to action
  • Creative that only makes sense to insiders
  • Running the same creative for a year without refresh
