Frequently Asked Questions
What is the correct Twitter / X header size?
The recommended Twitter (X) header size is 1500×500 pixels with a 3:1 aspect ratio. This fills the full banner on desktop. The maximum file size is 2 MB and accepted formats are JPG, PNG, GIF, and WebP.
What is the safe zone for a Twitter header?
Keep important content within the center 1260×340 px area. On mobile, Twitter crops the banner to approximately 600×200 px from the center — anything near the edges (especially corners) may be hidden. Your profile picture also overlaps the bottom-left corner.
What happens to my Twitter header on mobile?
On mobile devices, Twitter crops the header to a smaller region centered on the full banner (roughly 600×200 px). The top, bottom, and side edges are cut off. Design your banner with the key content centered to avoid cropping issues.
Can I use a PNG for my Twitter header?
Yes. Twitter accepts JPG, PNG, GIF, and WebP formats under 2 MB. Use PNG for graphics with text or logos (sharper edges, lossless). Use JPG for photographs to keep the file size under the 2 MB limit.
What aspect ratio is a Twitter header?
Twitter headers use a 3:1 aspect ratio — 1500 pixels wide and 500 pixels tall. If you upload an image with a different aspect ratio, Twitter will crop or letterbox it. Use this tool to resize to exactly 1500×500 before uploading.
