Best Yard Sign Sizes for Drive-By Visibility (2025 Guide)

Choosing the right yard sign size can be the difference between a quick glance and a clear message that drives action. This fast guide explains the most common sizes, how far they can be read, and when to use each—so your message lands from the street.

Common Yard Sign Sizes (and when to use them)

• 12×18 inches — Best for sidewalks or close foot traffic. Short messages, arrows, directional use.
• 18×24 inches (most popular) — Great balance of cost and visibility from the road. Fits standard H-stakes.
• 24×36 inches — Maximum impact for busy intersections or long driveways. Use when drivers need to read from farther away.

Readability: letter height vs. viewing distance

As a rule of thumb, every 1 inch of letter height ≈ 10 feet of readable distance. Keep your headline big and bold.

Letter Height	Approx. Readable Distance
2 in	~20 ft
3 in	~30 ft
4 in	~40 ft
6 in	~60 ft

Tip: For drive-by traffic, keep your main line under 7 words and use a bold sans-serif font (Impact, Bebas, Inter Black).

Material & Stake Tips

• 4 mm coroplast — Weatherproof, durable, best value for most campaigns.
• Aluminum — Long-term, premium look; great for permanent signage.
• H-stakes — Standard for 18×24. For larger signs, consider heavy-duty frames.

What Size Should I Choose?

• Real estate & business promos: 18×24
• High-speed roads / long driveways: 24×36
• Directional arrows / foot traffic: 12×18
