X (Twitter) avatar 400×400
Always rendered as a circle in timelines, replies and search. You upload a square and the platform applies the circle, so anything in the corners effectively does not exist.

Framing advice
- Keep the subject inside the central 80% circle and leave the edges clear so the crop cannot bite into a face or a logo stroke.
- 400 × 400 is the recommended size, not the minimum; upscaling a small file looks soft.
- Avatars on dark backgrounds look grey in light lists — a 2px translucent stroke fixes it.
The most common failure
Using a wide image with type as an avatar: after the circular crop only a letter or two is left and nothing is readable.
