X (Twitter) Profile Picture Size and How to Make a Round Icon

X (formerly Twitter) also displays profile pictures as a circle — in the timeline, replies, notifications, and more. X is one of the few platforms whose Help Center actually states a recommended size.

This guide covers X's official size guidance and how to build a profile picture that survives the circular crop.

According to X's official Help Center, the recommended profile picture size is 400×400px, with a 2MB file size limit. Supported formats are JPEG, GIF, and PNG — animated GIFs aren't supported for profile pictures. IconFit AI's default 1024×1024px output exceeds this recommended resolution, so it can be uploaded as-is.

Why profile pictures get cropped on X

A few situations commonly lead to a cropped subject on X.

Using a landscape photo as-is, with the subject off to one side
A photo of multiple people where the person at the edge of the frame ends up outside the circle
Upscaling a low-resolution image, leaving the edges blurry

Adjusting with IconFit AI

You can build an X profile picture with IconFit AI using the following steps.

Upload the image you want to use for X into IconFit AI
Review the AI-suggested composition ("Recommended" mode, centered on the detected face or subject)
Check how it looks in the "X" row of the social media preview
Switch to "Fill" or "Fit" mode if needed
Download as PNG or JPEG, then upload it from X's profile edit screen

Finishing touches

On X's timeline, profile pictures show up very small — around 48px. Fine details or small text can become hard to read at that size, so "Fill" mode, which keeps the subject large and simple, often works best.
