Upon visiting https://www.wikipedia.org/ I notice that all the icons for sister projects are inconsistent sizes ranging from 34px to 47px (commons)
24px by 24px has become the standard across all the other projects and it would be great to make these the same size and promote reuse.
If these were the same size, there wouldn't need to be css specific to each icon and the icons would be portable to other places such as OOjs UI and mw-ui-icon.
