Banner ads come in a small set of standard sizes. Using standard sizes means advertisers already have artwork that fits, and your placements look consistent. This guide lists the most common sizes, what they are called and where they usually work best.
| Size (pixels) | Name | Typical placement |
|---|---|---|
| 300×250 | Medium rectangle | In content, sidebar or below an article |
| 728×90 | Leaderboard | Top of the page or between sections on desktop |
| 160×600 | Wide skyscraper | Sidebar |
| 300×600 | Half page | Sidebar, a larger and more visible placement |
| 320×50 | Mobile leaderboard | Top or bottom of mobile pages |
| 320×100 | Large mobile banner | Mobile pages, a little more room than 320×50 |
| 970×90 | Large leaderboard | Top of the page on wide desktop layouts |
| 970×250 | Billboard | Prominent top-of-page placement on desktop |
| 468×60 | Full banner | Smaller sites and older layouts |
| 336×280 | Large rectangle | In content on desktop |
| 120×600 | Skyscraper | Narrow sidebar |
| 250×250 | Square | Sidebar or in content |
How to choose banner ad sizes for your site
- Start with two or three sizes. A 300×250 in the content or sidebar and a 728×90 near the top cover most sites. Add a 320×50 for mobile visitors.
- Match the size to the space. A banner that is wider than its container will be cropped or break the layout.
- Keep files small. Heavy banners slow the page down, and a slow page loses both visitors and advertisers.
- Use one size per placement. When several banners share a spot and rotate, give them all the same size.
Setting up sizes in AdPeeps
In AdPeeps you create a zone for each placement on your site and add banners of that size to it. To show more than one size together, such as a 468×60 and a 728×90, use companion ads. To rotate several banners of the same size, see how to rotate banner ads on a website and the banner ad rotator overview.
