How Ad Sizes Affect AdSense Earnings

AdSense Ad Sizes & AdSense Ad Units Affect Google AdSense Earnings

If you have been working with ads on your website for some time, it shouldn’t come as a surprise that the ad sizes you choose to display on your site can have a dramatic impact on AdSense earnings (we did a study on it here). There is absolutely no doubt that AdSense ad sizes — and types of AdSense ad units — affect revenue.

Depending on the layout of your site, the performance of different AdSense ad sizes can vary greatly. Generally speaking, AdSense has a few Google display ad sizes they recommend that are most effective. They are as follows:

Recommended Google Ad Sizes (most popular)

  • 336 x 280 large rectangle
  • 300 x 250 medium rectangle
  • 728 x 90 leaderboard
  • 300 x 600 half page
  • …and on mobile the 320 x 100 large mobile banner (not pictured here).
