X (Twitter) Image Size Cheat Sheet 2026

Q: What is the best image size for X (Twitter) posts?

FastEdit uses 1600x900 pixels for X post images, a 16:9 practical export target. JPEG is best for photos, while PNG can work for graphics and screenshots when the platform preserves it. Maximum file size target is 5 MB per image.

Q: What size is the X (Twitter) profile picture?

X profile photos should be 400x400 pixels. The image is displayed as a circle, so keep important content centered and avoid text near the edges. Supported formats are JPEG and PNG, up to 2 MB.

Q: What is the X (Twitter) header/banner size?

The X header banner should be 1500x500 pixels (3:1 ratio). The visible area varies between desktop and mobile, so place important content in the center. Maximum file size is 5 MB.

Q: Does X compress uploaded images?

Yes. X compresses uploaded images and may convert large PNGs to JPEG. To minimize compression artifacts, upload at the practical preset dimensions and avoid re-uploading previously compressed images.

Q: What image formats does X support?

X supports JPEG, PNG, GIF, and WebP for image uploads. However, PNGs larger than about 900,000 total pixels are converted to JPEG on upload. GIFs up to 15 MB are supported for animated content.

Q: What is the X (Twitter) video size limit?

X (formerly Twitter) allows video uploads up to 512MB for free users. Videos can be up to 2 minutes 20 seconds for free accounts, or up to 4 hours for Premium subscribers. Use MP4 with H.264 codec for best compatibility.

X (formerly Twitter) displays images at aspect ratios that vary between the feed, detail view, and profile sections. FastEdit targets 1600x900 for 16:9 posts, 400x400 for profile photos, and 1500x500 for headers. These practical presets reduce unexpected cropping and keep assets sharp.

Before you upload

X converts PNG images with more than 900,000 pixels to JPEG: use PNG only for small graphics and screenshots with text.
Timeline images are cropped to 16:9: design for this ratio to avoid unwanted cropping of important content.
Profile photos and header banners should have key content away from edges since they are cropped differently on mobile and desktop.
For predictable quality, export images at the preset dimensions rather than relying on X to resize them.
