Frequently Asked Questions

What is the most common web banner size?
The 300x250 Medium Rectangle is the most common display ad size, followed by the 728x90 Leaderboard and 160x600 Wide Skyscraper. These three sizes cover most ad placements.
What file size should web banners be?
Google Ads recommends keeping banner files under 150 KB. Use JPEG compression for photos, PNG-8 for simple graphics, or HTML5 for animated ads. Smaller files load faster.
What DPI do I need for a print banner?
For large banners viewed from a distance (6+ feet), 72-100 DPI is fine. For banners viewed up close (trade shows), use 150 DPI. For small prints, use 300 DPI.
