Typography plays a crucial role in the effectiveness of your OOH advertisement. Clear and readable text ensures your message reaches your audience quickly, especially when viewed from a distance or at a glance. This guide explains which fonts work best and how to apply them for maximum impact.

Font Style and Readability:

• Use bold, sans-serif fonts such as Helvetica, Arial, or Open Sans. These fonts are easier to read at long distances.
• Avoid decorative or script fonts, as they reduce clarity and take longer to read.
• Stick to all uppercase or title case for headlines to improve visibility. Avoid using all lowercase for key messages.

Font Size Recommendations:

• For billboards, use a minimum of 10 cm (approximately 72 pt) height per 10 meters of viewing distance.
• Digital OOH formats may require slightly larger fonts to ensure legibility under changing light or display conditions.
• Ensure spacing between letters (tracking) and lines (leading) is wide enough for quick reading.

Line Limits and Word Count:

• Keep headlines to no more than 7 words. The average viewer has about 3 to 5 seconds to read an ad.
• Use short and punchy phrases. Avoid long sentences or paragraphs.
• One clear message per design is more effective than trying to say too much.

Color Contrast:

• High contrast between text and background enhances readability.
• Avoid placing light-colored text on bright backgrounds or using similar color tones between text and images.
• Consider how lighting conditions may affect visibility, especially for digital screens.

Why It Matters:

Good typography helps deliver your message quickly, clearly, and with visual impact. Following these guidelines ensures your campaign stands out and connects with your audience even in high-traffic environments.
