Your Twitter/X header image is the large banner across the top of your profile page. It is one of the first things visitors see, making it an important part of your personal or brand identity on the platform.
Twitter/X Header Image Size
Twitter/X header images should be 1500×500 pixels (3:1 aspect ratio). The platform displays the image at various sizes depending on the device, so uploading at this recommended size or larger ensures quality on all screens. Maximum file size is 5MB for JPG/PNG.
How to Crop for Twitter/X Banner
Open imgresizr.com and upload your banner graphic. Use the Crop tool and manually enter a 3:1 ratio — you can type "1500" for width and "500" for height as custom dimensions. Make sure the most important content is centred horizontally and in the vertical middle, as Twitter crops differently on mobile. Resize to 1500×500 pixels and export as PNG.
Twitter Banner Safe Zone
Twitter applies dynamic cropping depending on device and browser. The safest approach is to keep all text and key visuals in the central 60% of the image (horizontally) and between 100px and 400px from the top. The profile picture overlaps the bottom-left corner on desktop view.
