looking at the ranking site, we don’t seem to have a banner.

I saw this too, thanks for doing something about it - I probably got distracted by something.

It would help us put our best foot forward by giving us our best bib and tucker.

One thing I have struggled with is dimensions/aspect ratio for banners. I did look this up and the advice I found was along the lines of, it’ll resize things, so don’t worry, which is fine as far as it goes but it does mean a banner will display differently.

On the web interface (through Chrome anyway) it goes with the original aspect ratio or there abouts - 1012 x 670 - 2:3 ish.

Liftoff seems to play nice with it:

Through Jerboa it gets trimmed hard:

Which is not the desired effect.

That last image is cropped to 1080 x 265 ish - 1:4

In fact, Liftoff wants a taller banner and starts to get messy when the height is lower:

That looks like it wants an image about 1080 x 683, so about 2:3.

You’ll might want to be roughly the shape of this banner from lemmy.world

This is 3726 x 1425 - similarish to this:

this one from monyet.cc.

This is 1080 x 405 - 3:8

Sooooo, tl;dr - my suggestion would be for a 2:3 banner that works when letterboxed down to at least 3:8 and perhaps even 1:4, although perhaps someone might want to have words with the Jerboa developers as that seems a very restrictive aspect ratio considering it is for mobile phone usage which is usually in portrait.

Format: PNG if possible.

Dimensions: tricky as you don’t want too large a file but some people might be viewing on a desktop. For now, perhaps 1080px wide but keep the original around in case we need it at a larger size.

And, yes, I over-think things.
