What is Twitter/X Video format?

Twitter/X videos display best at 1280x720 pixels (720p) in a 16:9 landscape aspect ratio. This resolution provides the best balance of quality and file size for Twitter's video player. Twitter supports various video dimensions but 16:9 is the standard that displays without letterboxing or cropping. Audio is fully supported in Twitter videos, and proper dimensions ensure your video plays smoothly.

How to resize for Twitter/X videos

  1. Upload your video — MP4, MOV, and WEBM formats supported up to 500 MB.
  2. Choose "Fit + Black Bars" to preserve the full video, or "Stretch to Fill" for full-frame 16:9.
  3. Download the 1280x720 video and share it on Twitter/X.
