X Profile Photo size at a glance
X profile photos display as circles everywhere — next to tweets, in notifications, in follower lists. A 400×400 source gives enough resolution for all display sizes.
Why 400×400 matters
Your avatar is your visual identity in every conversation. At 400×400 you get sharp rendering even on high-DPI screens without an oversized file.
What happens when the size is wrong
Non-square uploads get force-cropped into a circle. Low-resolution images look pixelated in larger display contexts like profile pages.
Best practices
- Center the subject with generous padding for the circular mask.
- Use high contrast — many X contexts show the avatar at 32-48px.
- Transparent PNG backgrounds show as white on X.
