What size is a Twitter header image?

The recommended Twitter (X) header/banner size is 1500×500px with a 3:1 aspect ratio. The minimum is 600×200px. Note that the profile picture overlaps the lower-left corner of the header, so keep important content away from that area.

What size should a Twitter profile picture be?

Upload your Twitter profile picture at 400×400px or larger (up to 2MB). Twitter displays profile pictures as circles, so use a square image and keep important content centred.

What is the best image size for Twitter posts?

For in-tweet images, use 1600×900px (16:9 landscape) for the clearest display. Twitter crops images to 600×335px in the timeline preview, so keep important content in the central area.

What is Twitter's image file size limit?

Twitter allows JPG and PNG images up to 5MB per image in tweets. GIFs up to 15MB. Profile pictures and headers up to 2MB.

Does Twitter crop my images?

Yes, Twitter crops images in the feed to a preview ratio. For single tweet images, the preview shows approximately 600×335px of a 1600×900px image. Twitter shows the full image when users tap on it.

Can I use a vertical image on Twitter?

Yes. Twitter supports vertical images. A 2:3 portrait image (e.g. 1080×1620px) displays reasonably in the feed. The preview will crop to roughly 600×750px.
