What is best size for retina images for room icons? I think you said for activity icons it’s 200x200, is that the same for rooms? I feel like they might be slightly longer in width than height?
The raw width of most of the displays for those is 128 non-Retina. So if you use a 128 and a 256 @2x, that’s ideal. The height is up to you within that, but the overall ratio of what is displayed will be roughly 16:9.
