Hello WMF developers!
On the English Wikipedia, we recently discussed the default size for thumbnail images, which is currently set to 220px. The result of the discussion is a consensus to increase default thumbnail size to 250 pixels. My understanding is that this is done by adjusting $wgDefaultUserOptions['thumbsize'] to 4 instead of 2, but that could be incorrect. In the past, this has been done for Swedish, Finnish, and other Wikipedias.
The relevant discussion can be found at https://en.wikipedia.org/wiki/Wikipedia:Village_pump_(proposals)/Archive_210#Increase_default_thumbnail_size_from_220px_to_250px
Thank you very much for your assistance! Mark, I'm tagging you just because WhatAmIDoing suggested you might have thoughts on scheduling.
Best,
