How do I change YouTube? - lemm.ee

Bad title but previously on subscriptions or home, there would be 4 (or maybe 5?) videos per row. Now it’s 3 and the thumbnails are bigger. It’s very annoying cause I have to scroll more and I don’t see the need to have the thumbnails be so large. How do I revert it? I’ve tried zooming out but then all the text gets smaller which I don’t want either. Thanks!
