Designing an effective outdoor advertisement is both an art and a science. Billboards and other outdoor media have just seconds to capture attention and deliver a clear message. Whether you’re creating a new billboard for Casablanca’s busy streets or updating an existing one, following these seven essential design rules will help ensure your ad stands out and drives results.
Keep It Simple
Outdoor ads need to be easily understood at a glance. Use minimal text—ideally no more than 7 words—and clear visuals. Avoid clutter, and focus on one main message or call to action. Simplicity improves recall and increases the chances your audience will act.
Use Large, Readable Fonts
Since your audience is often moving in vehicles or walking quickly, your text must be legible from a distance. Choose bold, sans-serif fonts with high contrast against the background. Avoid script or decorative fonts that slow reading and reduce clarity.
Prioritize Contrast and Colors
Bright, contrasting colors help your ad pop in urban environments. Use complementary color schemes and ensure your text stands out against backgrounds. Keep color choices consistent with your brand identity to build recognition.
Focus on Visual Impact
Strong imagery or graphics can communicate your message faster than words. Use high-quality photos, bold illustrations, or simple icons that relate directly to your offer. Remember, visuals are often the first thing noticed and remembered.

Include a Clear Call to Action (CTA)
Tell your audience exactly what you want them to do—visit a website, call a number, or attend an event. Make your CTA prominent and easy to remember, using simple language and actionable verbs.
Consider Viewing Distance and Angle
Place key information where it’s most visible—usually at eye level or facing traffic flow. Make sure no critical elements are blocked by structures, trees, or other signs.
Test and Refine
Whenever possible, test your design with real viewers or gather feedback before final printing. Small tweaks can make a big difference in effectiveness.
