If you wanted to know which themes on the WordPress.org theme directory have the highest number of active installs, you can see those here. The stats on this page are always current because they will be refreshed every seven days.
These are themes with the highest number of active installs, not necessarily the most “Popular” according to the WordPress theme directory. This is because the WordPress theme directory uses other metrics to calculate how “Popular” a theme is. They don’t simply use the number of active installs to calculate theme popularity. (This is okay because popularity has more to do with likability rather than just usage.)
Here, I just care about usage.
The list on this page includes the top twenty most active themes, starting with the number one theme with the most active installs. Please note that if two or more themes have the same number of active installs, then those are ranked in order of the highest rating based on the star ratings average.
Each theme will include its theme name, author, number of active installs, average rating, and a screenshot of the theme.
Please also note that the official themes by WordPress.org are excluded from this list because those are obviously well-represented among the top twenty since those are distributed with the WordPress package. However, themes by Automattic and/or WooThemes and/or Matt Mullenweg are fair game because those themes are not bundled with WordPress.
