What Size Should a Billboard Be?

When planning a billboard campaign, size matters. Ceat— bigger isn’t always better. The right billboard size depends on location, viewing distance, traffic speed, and your campaign goals.

What Is the Standard Billboard Size?

One of the most common large-format billboards in the U.S. is the bulletin, typically around 14 feet high by 48 feet wide. These are commonly found along highways and major roads, where advertisers need strong visibility from a distance.

Other common formats include:

  • Posters: Often around 10’5” x 22’8”, ideal for local roads and slower-moving traffic.
  • Junior posters: Smaller displays designed for neighborhood and local-market visibility.
  • Digital billboards: Available in many sizes depending on the location and display specifications.

Does a Bigger Billboard Work Better?

Not always. Location and visibility can matter more than size. A smaller billboard positioned near your target audience may outperform a larger billboard in a less relevant location.

Consider how quickly people will pass the ad, how far away they’ll see it, surrounding visual clutter, and how frequently your audience travels through the area.

How Much Should You Put on a Billboard?

Keep it simple. Even a huge billboard shouldn’t be packed with information.

Strong billboard creative typically uses a short headline, recognizable branding, bold imagery, and a simple call to action. Your audience may only have a few seconds to understand the message.

Choosing the Right Billboard Size

So, what size should a billboard be? There isn’t one perfect answer. Large highway bulletins can be great for broad visibility, while smaller formats can work well for targeted local campaigns.
