The most used and successful Banner Ad sizes in 2019

Different ad sizes and ad formats are best each at their department. While some increase ad impressions, the others achieve better click-through rates or memorable user experiences which convert post-view.

Discover in this post the most used banner Ad sizes of this year according to Google.

As a rule of thumb, wider ad sizes tend to outperform their taller counterparts, due to their reader-friendly format. Readers absorb information in “thought units,” several words at a time. Wider sizes let them comfortably read more text at a glance.

If positioned well, wide ad sizes can increase your earnings significantly. The sizes we’ve found to be the most effective are the 336x280 large rectangle, the 300x250 medium rectangle, the 728x90 leaderboard, the 300x600 half page, and on mobile the 320x100 large mobile banner. Keep in mind that while these ad sizes typically perform well, you should use the size that best complements your pages. It’s better to add one recommended ad unit than two smaller ad units next to each other.
