The rebrand from “Twitter” to “X” didn’t just change the logo—it confused everyone about the image sizes.

Does X use the same banner size as Twitter? Yes. Is the cropping logic the same? Mostly, but with one major catch.

The circular profile picture overlaps the bottom-left corner of your banner. If you put your logo or text there, it will be hidden.

(H2) What is the Correct Twitter / X Header Size?

Despite the name change, the official dimensions have remained consistent:

Recommended Size: 1500 x 500 pixels
Aspect Ratio: 3:1
File Type: PNG (Best for text), JPG, or GIF.

(H2) The Hidden Danger: The “Overlap” Zone

Unlike Facebook (where the profile pic is centered on mobile and left on desktop), X keeps the profile picture in the bottom-left corner on almost all devices.

The Problem: Your profile picture will block approximately 25% of the height of your banner in that corner.
The Fix: Use the “Check Overlap” button in our tool above. It projects a “Ghost Profile Pic” onto your image so you can move your text to safety.

(H3) Does the X Header size change on Mobile?

Yes. On mobile devices, the top and bottom of your banner are often cropped by the browser status bar or the app’s navigation menu.

Safe Zone: Keep critical text vertically centered. Leave about 60 pixels of “padding” at the top and bottom empty to avoid accidental cropping.

(H2) Frequently Asked Questions

Is X header size different from Twitter? No. The dimensions 1500×500 pixels work perfectly for both the legacy Twitter app and the new X app.

Why is my Twitter header blurry? This is a compression issue. X aggressively compresses JPG files. For the sharpest text, save your design as a PNG-24 file under 2MB.

Can I use a GIF as a Twitter Header? Yes, but it will not animate. It will display as a static image (usually the first frame of the GIF). Stick to high-quality static images for the best results.
