Top 10 Billboard Design Mistakes to Avoid

Designing a billboard may seem simple—but making one that actually grabs attention, communicates clearly, and drives action takes real strategy. At EyeCandyAds, we’ve helped hundreds of businesses design impactful billboards.

To help you avoid the most common pitfalls, here are 10 billboard design mistakes that can cost you attention—and potential customers.

1. Trying to Say Too Much

A billboard is not a brochure. If you’re cramming in every detail about your business, your message will get lost. Stick to one idea, one offer, or one call to action.

2. Font That’s Too Small

If people can’t read your ad while driving past at 60 km/h, it’s not working. Use large, bold fonts that can be read at a distance. Avoid thin, decorative, or script fonts.

3. Low Contrast Colors

Red text on a dark background or light gray on white just doesn’t stand out. Go for high-contrast color combinations to ensure your message pops—even in bright daylight.

4. Poor Image Quality

Low-resolution or pixelated images can damage your credibility. All visuals should be high-resolution and professionally formatted for large-scale printing or digital display.

5. Cluttered Layouts

Too many elements—logos, photos, QR codes, contact info—will overwhelm your viewer. A clean, well-organized layout draws the eye exactly where you want it to go.

6. No Clear Call to Action

People need to know what to do next. Whether it’s “Visit us today,” “Call now,” or just your web address, make your CTA clear and prominent.

7. Ignoring Read Time

One of the biggest mistakes is designing a billboard that takes too long to read. On average, a driver has just 5 to 7 seconds to glance at your ad. If it takes longer than that to understand your message, it won’t land. The key is to communicate quickly and clearly—ideally in seven words or fewer. Every word and design element needs to earn its place.

8. Inconsistent Branding

If your billboard ad looks completely different from your website or social media, you’re missing out on brand recognition. Keep your logo, colors, and tone consistent across all platforms.

9. Changing the Message Too Often

One advantage of digital billboards is the ability to change your creative quickly—but that doesn’t mean you should change it constantly. Frequent swaps can dilute your message and confuse your audience. Repetition is key in outdoor advertising. Stick with one strong design for at least a few days to build recognition before switching to a new version.

10. Designing Without Expert Help

DIY design tools can be tempting—but designing for large-format outdoor media is very different from making a social post. Our team at EyeCandyAds specializes in billboard design and knows exactly what works at scale.

Make Your Billboard Work for You

A billboard is an investment—and a well-designed one will pay off with attention, recognition, and results. Avoiding these common mistakes is the first step toward an ad that actually gets seen and remembered.
