Twitter (X) Image Sizes 2026 – What You Need to Know

Twitter, now rebranded as X, has specific image dimensions that affect how your profile and posts look. Using the correct Twitter image sizes prevents auto-cropping and ensures your content looks sharp.

Twitter profile photo size

Recommended upload: 400 × 400 px. Twitter displays profile photos as circles at approximately 48 × 48 px in timelines and larger (200 × 200 px) on profile pages. Upload at least 400 × 400 px for crisp display on high-resolution screens.

Supported formats: JPG, GIF, PNG. Maximum file size: 2 MB. Square images work best since Twitter crops to a circle.

Twitter header image size (banner)

Recommended: 1500 × 500 px (3:1 aspect ratio). The header image is displayed differently on desktop vs mobile. On desktop, the top and bottom are often cropped. Keep important content centered within the safe zone: approximately 1200 × 400 px in the center.

Supported formats: JPG, GIF, PNG. Maximum size: 5 MB.

Twitter tweet image sizes

For images shared in tweets, Twitter displays them at:

• Single image: Crops to 2:1 ratio in timeline (e.g., 1200 × 600 px). Full image shows on click.
• Two images: Each shown at approximately 1:1 ratio.
• Three images: One large left, two smaller right.
• Four images: 2×2 grid, each at approximately 1:1.

Best practice for single tweet images: 1600 × 900 px (16:9) or 1200 × 675 px. These display well without cropping in the timeline.

Twitter link card image size

When sharing a URL with an Open Graph image, Twitter displays a card. The recommended og:image size for Twitter cards is 1200 × 628 px.
