Cropped in your browser · your image is never uploaded

Local · multi-image posts crop to squares

1600 × 900. That is the ratio X shows in the timeline without cropping — anything else is cut to fit and expands only when someone taps it.

How to use the x / twitter post image size

1 Read the dimensions above. That is the whole answer if the spec is all you came for.

2 Drop your own image in to check it against the spec — size, aspect ratio and file weight are each checked separately.

3 Turn on the safe zone to see what gets cropped or covered, then download the cropped version at the exact size.

Multi-image posts change the geometry completely and this catches people out. One image is shown at 16:9; two are shown side by side, each cropped to a tall half; four are shown as a 2 × 2 grid of squares. So a 16:9 image that looks perfect on its own gets its sides chopped off when you add a second. If you are posting a set, design them square. On compression: X is harsher on JPEG than on PNG for graphics with flat colour and text, so screenshots and charts hold up better as PNG under the 5 MB limit.
