How many words should a mobile billboard have?

Keep the main message under about seven words. A mobile billboard is seen for only a few seconds, so one short, bold statement plus your brand and a single call to action works best.

What makes mobile billboard creative readable?

Large bold sans-serif type, high contrast between text and background, a single message, and brand plus call to action placed front and center. Test the design at thumbnail size to be sure it reads at a glance.

Can I change my LED truck creative during a campaign?

Yes. LED trucks display video files, so you can change creative anytime at no production cost, including running different designs by time of day.

Mobile Billboard Design Best Practices

Effective mobile billboard creative follows a few rules: one clear message, large high-contrast type readable from across a street, your brand and a single call to action front and center, and, on LED trucks, simple motion to draw the eye. People see the ad for only a few seconds, so simplicity wins.

1. One message per design

A mobile billboard is seen for a few seconds at most. Pick a single idea, one offer, one announcement, one brand statement, and cut everything else. Multiple messages compete and none land.

2. Make the type big and legible

Use large, bold, sans-serif type that reads clearly from across a street or intersection. As a rule of thumb, fewer than seven words on the main message. Avoid thin fonts, italics, and dense paragraphs.

3. Maximize contrast

High contrast between text and background is what makes a design readable in bright daylight and at night. Light text on a dark field or vice versa. On LED screens, saturated colors pop; avoid low-contrast pastels.

4. Brand and call to action up front

Your logo and a single call to action, a website, phone number, QR code, or event name, should be visible immediately. If someone only catches the ad for two seconds, they should still know who it is and what to do.

5. Use motion intentionally (LED)

On digital LED trucks you can use full-motion video, but keep it simple: a short loop, a reveal, or subtle movement that draws the eye to the message. Busy, fast-cutting video is hard to follow from the street. You can also change creative by time of day at no cost, morning versus evening, weekday versus event.

6. Design for the format

Build to the screen specs we provide so nothing important sits near the edges. Triple-sided trucks show the message on three sides, so the core design should work from every angle.

7. Test it small

View your design at thumbnail size on a phone. If you cannot read the message and identify the brand at a glance, simplify until you can. That is roughly how a passerby will experience it.
