X image and video sizes
The header is 1500 x 500 - and X says outright that 60 px off the top and 60 off the bottom can vanish depending on the screen.
Every frame below is drawn to scale against the others in its section, and every number carries the X page we read it on. Click a size to copy it.
Header and profile photo
X is the one platform that publishes its own crop, which makes the header the easiest safe zone on the internet to get right.
Drawn to scale against each other
- Top 60 px, croppable
- Bottom 60 px, croppable
X's own wording: at the recommended size, 60 pixels on the top and bottom could be cropped depending on monitor size and browser. That leaves 1500 x 380 that every visitor sees.
- Header photo1500x500
- Design inside the middle 1500 x 380. The bands above and below it are the ones X warns can be cropped.

Post images and video
X publishes its image sizes through its ad specs; the same frames are what an organic post is rendered into.
Drawn to scale against each other

- The safest single frame on X: it renders square on desktop and mobile, in the timeline and on a profile.
- 1:1business.x.com
- Post image, landscape1200x628
- The wide frame. X notes that a larger upload survives being expanded on click better.

- Post video, square1200x1200
- 140 seconds without Premium. With Premium, under 4 hours at 1080p - and over 2 hours it drops to 720p.

Questions
- What size is an X (Twitter) header?
- 1500 x 500 px. X warns that 60 px off the top and 60 px off the bottom can be cropped depending on monitor size and browser, so the part every visitor is guaranteed to see is the middle 1500 x 380.
- What size is an X profile photo?
- 400 x 400 px, under 2MB, in JPEG, GIF or PNG. It renders as a circle.
- What size should an image in an X post be?
- 1200 x 1200 for square or 1200 x 628 for the wide 1.91:1 frame. Square is the safer of the two because it renders the same on desktop and mobile.
- How long can a video on X be?
- 140 seconds on a free account, with a 512MB file cap. X Premium raises that to just under 4 hours at 1080p and 16GB, dropping to 720p past the 2 hour mark.

Pixels are the half of the rules the platforms publish and our engine does not enforce. The other half - file formats, size caps, how many images fit in one post, what our API path will accept - is generated from the engine's own table at X specs. Neither page restates what the other one owns.

If a header at the recommended size is cropped, it is because of how it is displayed across monitor sizes and browsers - 60 pixels on the top and bottom could be cropped.help.x.comverified 2026-08-25
