How X shows it

What can hide your header.

  • The top and the bottom. X says it may crop up to 60 pixels from the top and the bottom of a header, depending on the screen and the browser. The resizer stripes those bands.
  • Your profile photo. On a computer it sits at the bottom left, a little in from the edge, with its middle on the header’s bottom edge. Its top half covers that corner of the header. The resizer draws the circle there.
  • Phones. The header shows smaller, so fine print gets hard to read. Big shapes and short words work best.

Put faces, logos and words in the middle third, away from the bottom left, and the header reads the same everywhere. Bluesky crops its banner to the same 3:1 shape, so one picture works on both.

A profile worth visiting, replies worth reading.

Good replies send people to your profile. Twick drafts them in your voice right under the post, with 100% no AI slop, and you post the one you like.

FAQ

Header sizes, answered.

What size is the Twitter header?

1500 x 500 pixels, a 3:1 shape. X takes JPG, PNG or GIF files, but not animated GIFs.

What size is the Twitter profile picture?

400 x 400 pixels, up to 2 MB, as a JPG, PNG or GIF. On a personal account, X shows it as a circle.

Why does my Twitter header look cut off?

X may crop up to 60 pixels from the top and the bottom, depending on the screen and the browser, and your profile photo covers part of the bottom left. Keep words and faces near the middle.

Where does the profile picture cover the header?

On a computer, the photo sits at the bottom left, a little in from the edge, with its middle on the header’s bottom edge, so its top half covers the header. The resizer marks that spot.

Can I use the same header on Bluesky?

Yes. Bluesky crops its banner to the same 3:1 shape and takes PNG or JPEG files up to 1 MB.

Is my picture uploaded?

No. The picture is read, moved and cut in your browser, and the file you download is made there too. Twick never sees it.
