X/Twitter Image Sizes: Posts, Headers and Profile Photos
Published by Influence
Last checked
X recommends a 400 × 400 pixel profile image and a 1500 × 500 pixel header. For a single post photo, X says standard aspect ratios from 2:1 through 3:4 display in full. Choose a canvas for the actual content and inspect its preview; one image size does not suit a profile, header and post equally well.
The profile dimensions come from X’s profile-image help, while the single-photo display range comes from X’s photo-posting guidance. Recommendations and examples below are separated so an editorial canvas is not mistaken for a platform requirement.

Which X image size should you use?
| Placement | Dimensions or ratio | Status |
|---|---|---|
| Profile image | 400 × 400 px; 1:1 | X recommendation. Keep the recognizable subject clear in the preview. |
| Header | 1500 × 500 px; 3:1 | X recommendation. Cropping can vary by screen and browser. |
| Landscape single-photo post | 1600 × 900 px; 16:9 | Practical design example within the documented display range, not an X-required pixel size. |
| Square single-photo post | 1200 × 1200 px; 1:1 | Practical design example, not an X-required pixel size. |
| Portrait single-photo post | 1200 × 1600 px; 3:4 | Practical design example at the portrait end of the documented range. |
For profile uploads, X lists JPEG, GIF and PNG and a maximum file size of 2 MB. Do not apply that profile limit to every post or header. Check the selected upload route’s current validation for other media. X also warns that parts of a header can crop on different screens, so avoid placing essential information at its extreme edges.
How do you prepare an X image without losing information?
- Identify the placement before designing. A profile mark must work at a much smaller visible size than a post diagram.
- Choose the aspect ratio, then crop the source deliberately. Do not stretch the source to fill a different shape.
- Keep important labels, subjects and contact details clear of edges and overlapping interface elements.
- Export a real image file at the intended dimensions; changing the filename does not resize it.
- Inspect the composition on a narrow screen and in the actual upload preview.
- Write image descriptions that convey the useful visual information, including chart conclusions where needed.
A multi-image post can use a different preview layout from a single photo. Review the arrangement after attaching the complete set instead of assuming the single-photo rule describes every grid. When an image contains a detailed chart, supply the conclusion in the post text as well.

Requirement or design choice: [official specification or selected example canvas]
Source quality: [original resolution and crop] | Export: [format and actual file size]
Essential details: [what must remain visible] | Image description: [useful visual meaning]

What does a completed X image plan look like?
Fictional example
Fictional business: Cedar Desk. Post purpose: show the three checks to make before choosing a desk.
Placement: single-photo landscape post. Selected canvas: 1600 × 900 px, 16:9. This is our design choice within X’s documented single-photo range.
Composition: three large panels show the desk footprint, chair movement and a nearby door. Essential labels remain comfortably inside the canvas edges.
Image description: “Three checks before choosing a desk: mark its footprint, test the chair space and open nearby doors.”
Export review: inspect the actual image dimensions and file size, then confirm that all three panels remain legible in the upload preview.
Profile and header are separate designs: a 400 × 400 profile mark and a 1500 × 500 header. Do not shrink the three-panel instructional graphic into the profile image.
What should you do when an X image is cropped or blurry?
Check whether the problem exists in the source file, the export or the platform preview. A larger canvas cannot restore detail missing from a low-resolution source. If text becomes too small, reduce the amount of text or move the explanation into the post. If a header crops, reposition the essential subject and inspect the profile again at more than one width.
Use the social media accessibility checklist for readable image text and descriptions. When adapting the same idea to other networks, follow the cross-posting guide and each destination’s own dimensions rather than reusing one export blindly.
