| Image | Size | Limits | Notes | Source |
|---|---|---|---|---|
| Animated GIF | Up to 1280 × 1080 px recommended | Up to 5 MB on mobile and 15 MB on the web. The developer docs also recommend 350 frames or fewer. | Larger GIFs can fail when posting even if they upload. | Published by XX Help Center: How to post photos or GIFs on XX Developer Platform: Media upload best practices |

Link preview cards
| Image | Size | Limits | Notes | Source |
|---|---|---|---|---|
| Large image card (summary_large_image) | Not published by X today | X's developer site no longer has its Cards pages. Older versions described a 2:1 image under 5 MB; we couldn't re-check that. | A 1200 × 600 px (2:1) image is a safe choice. Test the link in a draft post before you rely on it. | Not verifiable |
Which post image ratios show in full
X shows a single photo in full when its aspect ratio is between 2:1 and 3:4. The pixel sizes are our suggestions: wide enough to stay sharp on high-density screens and well under the 5 MB limit as a JPG.
| Ratio | Suggested size | In the timeline | Good for |
|---|---|---|---|
| 16:9 landscape | 1600 × 900 px | Shown in full | Screenshots, slides and video thumbnails. |
| 1:1 square | 1200 × 1200 px | Shown in full | Quotes, charts and product shots. |
| 4:5 portrait | 1200 × 1500 px | Shown in full | Takes the most feed height while still showing in full. |
| 3:4 portrait | 1200 × 1600 px | Shown in full | The tallest ratio X says it shows in full. |
| 2:3 portrait | 1200 × 1800 px | Cropped preview | Taller than 3:4, so the timeline shows a crop. |
| 9:16 vertical | 1080 × 1920 px | Cropped preview | Phone screenshots and stories; cropped in the timeline. |
X changes limits without notice and its iPhone and Android apps can differ from x.com. Header crop measurements for phones are in our Twitter header size guide; to design a header from scratch, use the Twitter banner maker.

X image sizes, checked
Twitter header, profile picture and post image sizes in one place
X's own numbers are spread across several help pages and its developer docs, and many size guides still repeat figures from years ago. The table on this page lists each size with the page it comes from and the date we last checked it. Where X doesn't publish a number, we say so instead of guessing.
The short version: make your header 1500 × 500 pixels and your profile picture 400 × 400, both as JPG or PNG (profile pictures under 2 MB). Post photos can be up to 5 MB, and a single photo between 2:1 wide and 3:4 tall shows in full in the timeline. Taller images get cropped in the feed.
The resizer above the table does the cropping for you. Choose an image, pick a preset, decide whether to fill the frame or fit the whole image, move the crop if needed and download a PNG or JPG at the exact pixel size. It all runs in your browser; your image is never uploaded.

How it works
How to resize an image for X
Five steps, all in your browser.
Pick a preset
Header 1500 × 500, profile 400 × 400, or a post size in 16:9, 1:1 or 4:5.
Fill or fit
Fill crops the image to cover the frame; fit keeps the whole image and adds a background color.
Adjust the crop
Zoom in and move the image left, right, up or down until the subject sits where you want it.
Download
Save a PNG or a JPG at the preset's exact size, ready to upload to X.

Responsible use
Sizes change; we date every number
X changes its limits and layouts without notice, and its apps can behave differently from x.com. Every figure in the table links to its source with the date we checked it; if X's pages disagree, both values are shown. Use images you own or have permission to use.

FAQ
Twitter image size FAQ
Headers, profile pictures, post images and file limits.
What is the Twitter header size in 2026?
X recommends 1500 × 500 pixels for the header (also called the banner), a 3:1 ratio, as a JPG, PNG or static GIF. X's help center notes that up to 60 pixels at the top and bottom can be cropped depending on the screen, and phones also cut the sides, so keep text near the center.
What size should a Twitter profile picture be?
400 × 400 pixels, as a JPG, PNG or static GIF under 2 MB. X shows it as a circle, so keep faces and logos away from the corners.
What is the best image size for a Twitter post?
X doesn't publish a recommended pixel size for post images. It says a single photo with an aspect ratio between 2:1 and 3:4 displays in full. We suggest 1600 × 900 (16:9), 1200 × 1200 (1:1) or 1200 × 1500 (4:5), each under X's 5 MB limit.
Why does X crop my images in the timeline?
Images taller than 3:4 (such as 2:3 or 9:16) or wider than 2:1 don't fit the range X shows in full, so the timeline shows a cropped preview. People see the whole image when they tap it. Posts with several images are cropped to fit the grid.
What is the maximum file size for images and GIFs on X?
Photos can be up to 5 MB. Animated GIFs can be up to 5 MB on mobile and 15 MB on the web, according to X's help center. Profile pictures are limited to 2 MB.
Does the resizer upload my image?
No. The image is drawn on a canvas in your browser and the download is created on your device. Nothing is sent to Xholic or anyone else.
