About the Bluesky banner size
A Bluesky profile banner works best at 1500 by 500 pixels, a 3:1 landscape, the same shape as a classic header image on other networks, uploaded to a roughly 1 MB cap rather than a fixed pixel requirement. Your round avatar overlaps the bottom-left corner of the banner, and mobile trims the sides a little tighter than desktop, so keep any text or logo centred and clear of that lower-left zone. A simple graphic in your brand colours travels better across that crop than a busy photo with a subject near an edge.
