In my web browser, browsing the lemmy.today Web UI, looking at the homepage for the community, if I take a screenshot, the current banner appears to be displayed at 966x129; the actual underlying image is 4,000x533.

Looking at a different community’s banner [email protected], I get 966x240 visible in a screenshot, with the underlying image being 1,792x672.

So at least on my browser and viewed on that Lemmy frontend, I’m a little suspicious – without looking at the code – that 966 might be some kind of native target for width. It can clearly handle higher-res, and that might be desirable for some higher-resolution displays or clients, if they leverage that.

EDIT: Man, this should be on some kind of Lemmy community moderation wiki. Like, every moderator shouldn’t have to individually figure this out.

EDIT2: One reference to 960x240 that I can find is here, though as I said, it doesn’t appear to be quite right for native display resolution – on my browser, maybe just something wonky with me – and in that post, they point out that different themes can take advantage of higher resolution.

EDIT3: In the CSS, at least in the current default Lemmy Web UI, it looks like .banner has a max-height attribute of 240px, so I think that it’s safe to say that at least in that environment, it won’t grow past that.
