Twitter (X) Image Sizes: The Complete 2026 Guide
X crops timeline images to a preview ratio, so the wrong dimensions mean your punchline or product gets chopped until someone taps. These are the four sizes that matter in 2026 — get them right and your images display exactly as composed.
| Use | Dimensions | Ratio | Notes |
|---|---|---|---|
| Profile picture | 400 × 400 px | 1:1 | Displays as a circle everywhere — keep the subject centered and avoid corner text. |
| Header photo | 1500 × 500 px | 3:1 | Your profile picture overlaps the bottom-left, and phones trim the top and bottom edges — center the key content. |
| In-stream image | 1600 × 900 px | 16:9 | 16:9 displays uncropped in the timeline, so what you post is what people see. |
| Card image (link preview) | 1200 × 628 px | 1.91:1 | The summary-card image shown when a URL is shared — small text becomes unreadable at feed size. |

Pro Tips
- X preserves PNGs under 5MB without recompression — use PNG for screenshots and graphics with text.
- Single 16:9 images show full-width and uncropped in the timeline; odd ratios get center-cropped previews.
- Header photos render behind translucent UI on mobile — avoid putting text near the very top or bottom 60px.
- Multi-image tweets crop each image to a square-ish grid, so keep subjects centered when posting 2-4 images.
Frequently Asked Questions
Why does X crop my images in the timeline?
The timeline shows a fixed-ratio preview, and images that do not match get center-cropped until clicked. Posting at 16:9 (1600 × 900) makes the preview and the full image identical, so nothing gets cut.
Does X compress uploaded images?
JPGs are recompressed, but PNGs under 5MB are generally left untouched, which is why screenshots stay crisp. For photos, upload a high-quality JPG at the exact display size to minimize visible artifacts.
