Conclusions

1. In all experiments, there are two banner formats which provide more than 50% reach: 300x250 and 728x90. So, this set is appropriate for those who want to simplify the work of a designer.
2. The standard brand campaign consists of seven banner formats— they provide more than 95% of the total reach. Another question is howlarge these banners should be. It is very likely that the formats will be 728x90, 300x250, 160x600, 336x280. But still, it’s better to make banners of all sizes.

I hope this statistic will help you decide on the best options for banner advertising on the Google Display Network.
