The details
Facebook says covers load fastest as an 851×315 sRGB JPG under 100KB; the minimum is 400×150. The visible crop differs between desktop and mobile, so treat the outer edges as disposable.
Safe area: Desktop shows roughly a 16:9 slice and phones about 2.4:1 — keep text and faces near the horizontal center so neither crop cuts them.
