X, formerly Twitter, has specific image dimension requirements that trip up a lot of creators and businesses. Getting these wrong means your header photo appears blurry, your profile photo looks cropped oddly, or your tweet images don't display the way you intended. This guide covers every image format on X with the exact dimensions you need.
X Profile Photo Size
X profile photos should be uploaded at 400×400 pixels minimum, though X supports uploads up to 2MB. Profile photos are displayed as circles across X, so make sure your key content (face, logo) is centred and stays well within the frame — particularly avoiding the corners.
X automatically applies a circular crop on all profile photos displayed in tweets, search results, and the profile page. PNG is recommended for logos with transparent backgrounds; JPEG works best for photographs.
X Header / Banner Size
The X header banner is the large image displayed at the top of your profile page. The recommended size is 1500×500 pixels with a 3:1 aspect ratio, and file size should be under 5MB. This is a wide, landscape banner — think of it as a billboard for your brand.
Important: the profile photo overlaps the bottom-left of the banner on desktop and mobile. Keep critical content (text, logos, important imagery) away from the bottom-left corner and from the extreme left and right edges which may be cropped on smaller screens.
In-Tweet Image Sizes
Images attached to tweets display at a maximum of 1200×675 pixels (16:9 ratio) for single images. When you attach 2 images, each displays at approximately 600×675px side by side. Three or four images display in a 2×2 grid. For optimal display quality across all configurations, upload images at 1200×675px and under 5MB per image.
