I’ve been toying around with this for awhile now and even as I thought I had a good idea of the right scale for icons/banners, Lemmy’s tripped me up.

Searched in other communities & looked on other instances at some of their community icons/banners that look good, but there doesn’t appear to be much consistency. You see some 512x512 icons right alongside 256x256 icons and they both tend to look okay.

However in trying to emulate this with some images, I find the “previews” to be unhelpful, appearing to clip or sometimes stretch them.

Any advice would be much appreciated!
