Banner sizes

bannerpixelsshapefile
LinkedIn profile1584 × 3964:1JPG or PNG, under 8 MB
LinkedIn company page1512 × 256about 6:1PNG or JPEG, up to 3 MB
X (Twitter) header1500 × 5003:1JPG, PNG or still GIF

These come from LinkedIn's help on profile banners and company pages, and X's profile help. X's help gives no file size limit for headers.

Many guides still say 1128 × 191 for a company page, but LinkedIn's help now says 1512 × 256.

Where the photo covers your banner

We measured the live sites in a browser on 7 November 2026, at desktop width and at 390 pixels wide.

LinkedIn company pagethe left quarter of the lower two thirdsthe left 47% of the bottom quarter
X headerthe left quarter of the bottom thirdthe left quarter of the bottom third

On LinkedIn the photo stays the same size as the page narrows, so it takes far more of the banner. Keep text and logos in the right half there. On X, the right 70% is clear, and X's help warns that 60 pixels can be cropped from the top and bottom, so keep those clear too.

Questions

Is a Twitter header the same as an X header?

Yes. It's the same image at the same recommended size, 1500 × 500 pixels. X's help also calls it a banner.

What if my image is a different shape?

The checker crops it to the right shape. Drag it to choose the part that shows, and zoom in if you want less of it.

What do I get when I download?

A PNG at the exact size, which always fits inside LinkedIn's file limits. Any transparent parts turn white.

Does it upload my image?

No. The tool runs in your browser and your image never reaches us. Nothing is kept after you leave the page.
