Three rules that never change
Design at 2× when in doubt. Platforms compress everything; oversized uploads survive compression better than exact-size ones.
Respect safe areas. Vertical formats lose the top and bottom to usernames, captions and buttons — keep anything important in the middle 80%.
One image rarely fits all. Resize per platform with the aspect ratio calculator instead of letting each app auto-crop your subject's head off.
