Twitter (X) image sizes
Pick a size, drop in an image, and download it exactly as X wants it: header, profile photo or post. The overlay shows what X covers or crops. Your image never leaves your device.
What size is a Twitter header?
A Twitter (X) header is 1500 × 500 pixels, a 3:1 ratio, in JPG, PNG or GIF. X notes that about 60 pixels at the top and bottom can be cropped on some screens, and your profile photo covers part of the lower-left on desktop, so keep text in the middle band and the right two-thirds.
What size should a Twitter post image be?
Any single photo between 2:1 (wide) and 3:4 (tall) shows in full in the feed. 1920 × 1080 (16:9), 1080 × 1080 (square) and 1080 × 1440 (3:4) all fit, and 3:4 takes up the most room on a phone screen.
