Banner Size Calculator
How It Works
Banners need to be sized appropriately for their viewing distance and environment. Indoor banners for trade shows and conferences can be smaller since viewers are closer, while outdoor banners for storefronts and events need to be larger for visibility at greater distances.
The key rule for banner readability is that letter height should be at least 1 inch per 25 feet of viewing distance for the main headline. Supporting text should be no smaller than 1 inch per 10 feet. For outdoor banners, increase these sizes by 30-50% to account for viewing conditions.
Banner resolution (DPI) can be lower for larger viewing distances. Banners viewed from 20+ feet only need 72 DPI, which makes file sizes manageable. For banners viewed up close, use 150-300 DPI for sharp text and images.
Frequently Asked Questions
What are common banner sizes?
Common indoor banner sizes are 2x6, 3x6, and 4x8 feet. For outdoor banners, 3x8, 4x10, and 3x12 feet are popular. Retractable banners are typically 33x80 inches.
What material should I use for outdoor banners?
13oz vinyl is the most popular outdoor banner material — it is durable, waterproof, and wind-resistant. For short-term outdoor use, mesh banners allow wind to pass through, reducing stress on grommets.
How do I hang a banner?
Use grommets (metal eyelets) every 2-3 feet along the edges. For indoor use, banner stands or adhesive hooks work well. For outdoor installation, use bungee cords or zip ties to allow some flexibility in wind.
What file format should I use for banner printing?
Use PDF, AI, or EPS for vector graphics (best for text and logos). For photographic banners, use high-resolution TIFF or JPG. Always set up your file at the actual banner size with appropriate bleed (0.25-0.5 inches).
