# Resize Images for X (Twitter)

Make images fit the shapes X shows best, so your post is not cropped in the timeline and your header does not lose its edges. Crop to fill or keep the whole picture on a blurred background.

**Quick answer:** 1600 × 900 pixels (16:9) is the commonly recommended size for single images in posts on X, and X suggests 1500 × 500 for the header and 400 × 400 for the profile photo. Pick a size here, choose crop or fit, and download a JPG, resized in your browser.

## How to use it

1. Choose your images.
2. Pick the size: 16:9 post image, square post image, header or profile photo.
3. Keep Fit, blurred background to show the whole picture, or choose Crop to fill.
4. Press Resize for X and attach the result to your post or profile.

## Recommended X image sizes

| Where | Shape | Recommended size |
| --- | --- | --- |
| Single image in a post | 16:9 | 1600 × 900 px |
| Square image in a post | 1:1 | 1200 × 1200 px |
| Header | 3:1 | 1500 × 500 px |
| Profile photo | 1:1, shown as a circle | 400 × 400 px |

These are recommendations, not requirements: X accepts other sizes and scales or crops them for display. The header and profile sizes are the ones X's help pages suggest, 1200 × 1200 matches X's ad specifications for square images, and 1600 × 900 is the widely recommended size for a single landscape image. X changes its layout from time to time, so a preview before posting is always worth a look.

## Why 16:9 avoids the crop

In the timeline X shows a preview of each image, and a very tall or very wide picture may be cut to fit that preview until someone taps it. A 16:9 image generally fits the preview as it is. With **Fit, blurred background**, a portrait photo or a screenshot is placed whole in the 16:9 frame, with a blurred copy filling the sides, so nothing important sits outside the preview.

Posts with two to four images are arranged in a grid and cropped differently, so for those keep the subject in the middle of each picture.

## Header and profile photo

The 3:1 header is wide and gets partly covered by your profile photo in the lower left, and it is shown at different widths on phones and computers. Use **Crop to fill** and a picture whose interesting part is in the middle band. The profile photo is shown as a circle, so keep your face in the centre.
