Frequently Asked Questions
What is the best image size for a Twitter / X post?
1600×900 px (16:9 ratio) is optimal for Twitter post images. It fills the maximum preview area in the feed without letterboxing. Twitter also supports 1:1 and 4:5 ratios for portrait posts.
What size is the Twitter / X header banner?
The recommended Twitter header size is 1500×500 px (3:1 ratio). Note that the top and bottom edges can be cropped on some devices, so keep key content centered vertically.
What size should a Twitter profile picture be?
Upload at least 400×400 px. Twitter displays profile pictures as circles, so make sure the subject is centered. Higher resolution uploads remain sharp when displayed at larger sizes.
Does X / Twitter compress images?
Yes. Twitter converts uploaded images to JPEG and WebP. Uploading at the correct dimensions and exporting with minimal JPEG compression (quality 90+) gives the best result after Twitter's encoding.
