Ways to stand out

Billboards don't have to be flat rectangles with words on them. Ways to get noticed:

Static boards

Printed boards, with a twist.

  • Extensions

    Break the frame.

    Part of the art pops past the edge of the board. In a row of rectangles, the one that breaks the shape gets the look.

  • LED lights

    Own the night.

    Lights built into the artwork make parts of a printed board glow after dark: a logo, a sign, headlights, a neon look.

  • 3D props

    Make it real.

    Real objects mounted on the board, like a car or a giant product. People photograph them and share them.

  • A series

    Tell a story.

    A set of ads that build on each other over weeks or along one route. People start looking for the next one.

Digital boards

LED screens that change on their own.

  • Countdowns

    Build the buzz.

    “12 days until opening.” The number updates itself every day.

  • Social posts

    Your feed, 48 feet wide.

    Show your posts or customer photos. After an event, put the crowd's photos up.

  • Day and night

    Two ads, one board.

    One design while the sun is up, another after dark.

  • Time of day

    Right ad, right hour.

    Lunch specials at 11, happy hour at 4, late-night menu at 10.

  • Live info

    Make it current.

    Weather, scores or gas prices, live. “Ice cold drinks” on a 100-degree day.

AI is a great start. Here's what it misses.

ChatGPT and other AI tools are great for ideas. But a billboard is printed 48 feet wide and read at 65 mph. These are the problems we see most in AI-made billboards:

Wrong size

AI makes squares or wide-screen images. A 14' × 48' board is 3.43 to 1, so the billboard company has to stretch or crop it.

Too small to print

Most AI images are 1,000 to 2,000 pixels wide. A highway board needs about 7,000, or it prints blurry.

Too many words

Drivers catch about 7 words. AI loves taglines, bullet points and long lists.

Fake or misspelled letters

AI often scrambles letters, phone numbers and web addresses. One wrong digit and the board can't bring you calls.

Tiny contact info

Phone numbers and websites that look fine on a phone screen disappear from the road.

Busy backgrounds

Detailed scenes and low-contrast colors turn into mush from 500 feet away.

What works on a billboard

5 sec

That's how long drivers look

At highway speed, people glance at a billboard for about five seconds. One short message wins.

7

Words or fewer

Your message, your name, and one way to find you. Anything more gets missed.

Bold

Big letters, strong colors

Dark on light or light on dark. If you have to squint on your phone, drivers can't read it.

Billboard sizes explained

Billboard companies use a few standard shapes. Your file has to match exactly, or it gets stretched or cut off.

Every kind of outdoor ad

Billboards are just one kind of out-of-home (OOH) advertising. We design for all of them.

Highway bulletins

The big 14' × 48' boards on interstates and major roads.

Posters

30-sheet (about 10' × 22') and 8-sheet junior posters on city streets.

Digital billboards

LED screens that rotate several ads. Exact pixel sizes, like 1400 × 400.

Wallscapes

Huge ads painted or hung on the sides of buildings. Custom sizes.

Bus and transit

Bus sides, tails and wraps, plus train and subway ads.

Bus shelters & benches

Street-level ads people see up close while walking or waiting.

Airports & malls

Indoor displays and screens where travelers and shoppers pass.

Billboard questions, answered

Can I design my billboard with ChatGPT or another AI tool?

Yes, and it's a great way to start. AI is fast at ideas, colors and layouts. But AI image tools usually make the file the wrong shape and too small for a billboard, and they often misspell words or invent letters. Upload your AI design here to check it, then have a billboard specialist make the final, print-ready file.

What size should my billboard file be?

It depends on the board. A 14' × 48' highway bulletin is 3.43 to 1 (often built at 1/2 inch = 1 foot, or 7,000 px wide or more). A 10' × 30' is 3 to 1. A 30-sheet poster is about 2.2 to 1. Digital billboards need the exact pixel size from the billboard company, such as 1400 × 400. Pick your board above and we tell you the exact size.

How accurate is the score?

It's a ballpark estimate. The score checks your design against the rules that make billboards work (size, word count, lettering, contrast, one clear next step) so you can tell if you're headed in the right direction. It can't judge everything a trained eye can. For real feedback on your design, talk to a specialist. It's free.

What resolution does a billboard need?

Billboards are seen from far away, so they don't need magazine-level detail, but most AI images (around 1,000 to 2,000 pixels wide) are still too small. For a 14' × 48' print board, aim for at least about 7,000 pixels wide, or vector files. Digital boards need the exact pixel size, no smaller.

How many words should a billboard have?

Seven words or fewer is the classic rule. Drivers look at a billboard for about five seconds. Use one message, your name or logo, and one way to find you.

How much does a billboard cost?

It varies a lot by city and location. Rough 2026 ranges: about $250 to $1,500 a month in small markets, $1,500 to $9,000 in mid-size markets, and $5,000 to $25,000+ in major cities. Digital boards often cost more than static. Tell us your city and budget and we'll find real options.

How do I rent a billboard?

You lease billboard space from the company that owns the board, from national companies to local independents. Prices depend on the city, traffic and how long it runs. Before you sign, make sure your artwork is ready. Rate it here, then book a free consult.

Don't billboard companies design my ad for free?

Many include basic design with your lease. We're a specialist second opinion: we make sure your artwork is built to spec and actually works at 65 mph before you commit, and we can rebuild it if it doesn't.

What other outdoor ads can you help with?

All kinds of out-of-home (OOH) advertising: highway bulletins, posters, digital billboards, wallscapes, bus and transit ads, bus shelters, benches, airport and mall displays.
