Google Display Network ads come in several standard sizes. The most common are 300x250 (medium rectangle), 728x90 (leaderboard), 160x600 (wide skyscraper), 336x280 (large rectangle), 320x50 (mobile leaderboard), 300x600 (half page), and 970x250 (billboard).
The top-performing sizes are 300x250 and 728x90, so prioritize these when creating display ad creatives. All images should be clean, have a clear call-to-action, and comply with Google Ads image policies.
With ImgTools, create each ad size variant by cropping and resizing your source design to the required dimensions. Save as JPEG at 85% quality or PNG for text-heavy ads. Keep file sizes under 150KB for fast ad loading.
