Twitter (X) header size (2026): 1500 × 500 px

A Twitter (X) header should be 1500 × 500 pixels, a 3:1 ratio, as a JPG, PNG or GIF. The profile photo covers the lower-left corner, so keep text and faces away from it.

We measured the profile photo on X's desktop profile on 2026-10-10: it covers about x 35 to 401 and y 312 to 500 of the header, drawn here with a small margin. The lower-right button area is a third-party mobile figure. The 60 px bands at the top and bottom follow X's note that up to 60 px there can be cropped.

How X (Twitter) shows your image

  • X says up to 60 px at the top and bottom of the header can be cropped, depending on monitor size and browser.
  • The profile photo overlaps the lower-left corner. On desktop it covers about 366 × 188 px of the header (x 35 to 401, y 312 to 500), larger than the 220 × 220 some guides quote.
  • On mobile a button can cover about 200 × 100 px in the lower-right corner, according to third-party guides.
  • Linearity reports that X trims about 50 px from the top and bottom on mobile, close to X's own 60 px figure.

How to resize and upload

  1. 01Pick the Header 3:1 preset in the resizer above.
  2. 02Drop in your image. If it comes from another platform's banner, read the reuse section below first: a 4:1 LinkedIn banner has to be enlarged to fill 3:1.
  3. 03Move the image until the subject is in the center, or use Detect subject.
  4. 04Turn on Show safe zone and keep text and logos inside the dashed box.
  5. 05Download as JPG for photos or PNG for text, then upload it from Edit profile on X.
  6. 06Open your profile on a phone and a computer and check both crops.

Common mistakes to check before you post

  • Putting a logo or name in the lower-left corner, where the profile photo sits.
  • Placing a call to action in the lower-right, where the mobile button covers it.
  • Using a 16:9 post image as a header. Cropping 16:9 to 3:1 removes about 40% of its height; crop it deliberately instead.
  • Uploading at a smaller size than 1500 × 500, which looks soft on large screens.
  • Treating the 400 × 400 profile photo size as the header size; they are different images.

The header at a glance

X's help page recommends 1500 × 500 for header images and 400 × 400 for the profile photo, accepts JPEG, GIF and PNG, and caps profile photos at 2 MB (X Help Center). The same page says that on some monitors and browsers up to 60 px at the top and bottom of the header can be cropped.

The ratio is 3:1, a little taller than a 4:1 LinkedIn profile banner, which leaves slightly more vertical room.

Worked example: the clear area

On X's desktop profile, the photo covers about x = 35 to 401 and y = 312 to 500 in header pixels. Third-party guides put the mobile Follow or Edit button at x 1300 to 1500 and y 400 to 500. Text between x = 420 and x = 1280 avoids both. Leaving 60 px at the top and bottom, the amount X says can be cropped there, gives a clear area of 1280 − 420 = 860 px wide by 500 − 120 = 380 px tall.

That is 860 × 380, about 2.3:1: 57% of the header's width and 76% of its height. If a design needs the full width, keep text above y = 300; the band from y = 60 to 300 is clear edge to edge.

Posts, photos and ads on X

X's help page accepts JPEG, PNG and GIF photos up to 5 MB, with animated GIFs up to 15 MB on web and 5 MB on mobile. It gives no pixel size, but says a single photo between 2:1 and 3:4 displays in full (X Help Center). X's API docs add WEBP and allow up to 4 photos per post (X API docs). 1200 × 675 (16:9) is the post size third-party guides such as Linearity use; how multi-photo grids are cropped is not published.

For standalone image ads X recommends 1200 × 628 at 1.91:1 or 1200 × 1200 square. Image ads with app buttons, polls or a website card use 800 × 418 or 800 × 800, and conversation-button ads use 800 × 418. Files are PNG or JPEG up to 5 MB, and GIFs render as a static image (X Ads creative specs).

Reusing a banner from another platform

A 16:9 image such as a 1920 × 1080 Discord server banner crops to 3:1 at 1920 × 640, keeping 59% of its height, then scales down by 0.78 to 1500 × 500. Decide which 640 rows to keep before you crop.

A 4:1 LinkedIn profile banner is the opposite problem. Cropping 1584 × 396 to 3:1 keeps 1188 × 396, which has to be enlarged by 1.26 to reach 1500 × 500, so it will look soft. Rebuild it from the original artwork instead.

A 2560 × 1440 YouTube banner crops to 2560 × 853 and scales by 0.586. Its 1546 × 423 center text strip then lands at about 906 × 248 in the middle of the header, from x = 297 to 1203 and y = 126 to 374. Its lower-left corner (left of x = 420, below y = 300) sits behind the profile photo, so keep text in the upper or right-hand part of the strip.

What we could not confirm

  • help.x.com blocks automated fetches; we read the help pages in a browser on 2026-10-05.
  • The 5 MB header limit and the 200 × 100 mobile button zone are third-party figures. We measured the profile photo zone on X's desktop site on 2026-10-10; the iOS and Android apps may place it differently.
  • X does not publish a recommended pixel size for organic post images; 1200 × 675 is a convention.
  • How X crops multi-photo grids is not published.

Twitter (X) header size FAQ

What size is a Twitter (X) header?

1500 × 500 pixels (3:1). Keep text inside the clear 860 × 380 px area (x 420 to 1280, y 60 to 440) so the profile photo, the mobile button and X's 60 px top and bottom crop don't cover it.

What size is a Twitter (X) profile picture?

400 × 400 pixels, JPEG, GIF or PNG, up to 2 MB. It is shown as a circle for most accounts.

Why is my X header cropped?

X says up to 60 px at the top and bottom can be cropped depending on monitor size and browser, and the profile photo covers the lower-left corner. Keep key content in the center.

What size should an X post image be?

X publishes no pixel size, but shows a single photo between 2:1 and 3:4 in full. 1200 × 675 (16:9) is a common choice; the file limit is 5 MB.

What size is an X image ad?

1200 × 628 (1.91:1) or 1200 × 1200 for a standalone image ad, PNG or JPEG up to 5 MB. Image ads with app buttons, polls or a website card use 800 × 418 or 800 × 800, per X's ad specs.
