Open Twitter/X Profile Picture SizeThe 400×400 sweet spot
X recommends a profile image of at least 400×400 pixels for a visible crop on desktop and mobile. Larger files are downscaled; smaller ones risk a soft avatar in replies and search.
Prepare your avatar
- Open the Resize Image tool.
- Drop in your headshot or logo.
- Enter 400 for both width and height — or crop to square first.
- Export as JPG for photos or PNG for logos with background.
Center your face or mark: X crops the avatar to a circle on some surfaces.
Small file, big brand
A 400×400 avatar compresses to 30-80KB — nothing for the network to slow down. Consistency across replies, mentions and search is what a correct resolution buys you.

Frequently Asked Questions
What size is a Twitter profile photo?
400×400 is the ideal resolution. It covers desktop, mobile and search surfaces with no upscaling.
Is the avatar shown as a circle?
Yes, on most surfaces. Crop to square and keep your subject centered so the circular mask never clips it.
What about the header at the same time?
The X header is 1500×500 — use our dedicated header guide and resize tool preset after the avatar.
