X (Twitter) post image size in 2026
The recommended X (Twitter) post image image is 1600 × 900 px, an aspect ratio of 16:9. Displayed uncropped in the timeline at this ratio. X shows single images at 16:9 in the timeline and crops others to that ratio in previews, so a 1600 × 900 image is displayed without cropping. Header images are cropped on mobile at the top and bottom; profile pictures are round.
How this tool fits your photo
Most photos are 4:3 or 3:2, not 16:9. Rather than stretching, this tool scales the photo until it covers the 1600 × 900 frame and then crops equally from the edges that overflow. For a portrait photo going into a landscape slot, that means the top and bottom are trimmed; for a landscape photo going into a portrait slot, the sides. If the subject is off-centre, crop it roughly first in your phone's editor, then use this tool for the exact pixels. Images smaller than 1600 × 900 are enlarged, which softens them slightly; start from the largest original you have.
