What size is an X (Twitter) header?
The widely recommended header size is 1500 × 500 (3:1). Your profile photo overlaps the lower-left corner, so keep important content away from that area.
What size should images in posts be?
1600 × 900 (16:9) shows in full in most timelines; square 1080 × 1080 images work well too.
What size is a profile photo?
400 × 400 px. X shows it as a circle, so keep the subject centred.
Will my image be cropped?
Only if you choose Fill. Drag the image to choose what stays in frame and use Zoom to tighten it. Choose Fit to keep the whole image — the empty space is filled with a blurred copy of your photo or a solid colour.
Are my images uploaded?
No. Resizing happens in your browser, so your photos never leave your device.
