Mobile developers and publishers continue to release heavier games, as the average file size on the US App Store has grown 76% in the last five years.

The statistics have been shared by Sensor Tower. “We looked at the top 100 revenue generating mobile games on the US App Store each year since 2016, and determined each title’s file size based on storage requirements at the end of the year,” says Craig Chapple, Mobile Insights Strategist at Sensor Tower.

It’s worth noting that the file size doesn’t include additional content.

While the average file size for a mobile game in 2016 was 264 Mb, it increased to nearly 465 Mb in 2020. The median size increased even more, growing 102.6% over the last five years — from 147 Mb to almost 299 Mb.
