Social profile photos
X recommends a 400×400 profile image, and LinkedIn accepts a 400×400 square for company logos. Uploading at the exact size means the platform crops predictably instead of shrinking a larger file unevenly.
The same square suits Slack and many chat-app avatars. Since the resize runs locally, your headshot or brand logo is never handed to a third-party server during the process.
Designing for a circular crop
X and many apps display the 400×400 square as a circle, clipping the corners. Keep faces and logo marks within the central circle so nothing important gets cut.
At 160,000 pixels the image is small, so a busy logo with fine text can turn muddy. Simplify to a clear mark or monogram that reads at avatar size.

Frequently asked questions
What size should a Twitter (X) profile photo be?
400×400 is the recommended size. X displays it as a circle, so center your face and leave a little margin around the edges.
Can I use 400×400 for a LinkedIn company logo?
Yes. LinkedIn accepts a 400×400 square logo. Use a transparent or solid background and keep the mark centered so it reads well when shrunk.
Will a 400×400 logo look sharp?
For a simple mark, yes. Detailed logos with small text can blur at this size, so simplify to a bold, legible version for social profiles.
