X (Twitter) Video Size
X video is 1920 × 1080 px (16:9) at its standard resolution. X accepts aspect ratios from 1:2.39 to 2.39:1, which covers vertical, square, and cinematic widescreen. Standard accounts are capped at 512 MB and 2 minutes 20 seconds; premium tiers raise both substantially. MP4 with H.264 video and AAC audio is the reliable container.

Design Tips
- →Square (1080 × 1080 px) or 4:5 portrait outperforms 16:9 in the timeline for the same reason it does elsewhere — it occupies more vertical space in a vertical scroll.
- →Burn in captions. X autoplays video muted in the timeline, and there is no reliable auto-caption layer to fall back on.
- →Keep captions and lower thirds above the bottom 15% of the frame. The playback scrubber and duration overlay sit there during playback.
- →Standard accounts are limited to 2 minutes 20 seconds. Plan the edit around that ceiling rather than discovering it at upload.

What is the Twitter video size?+
1920 × 1080 px (16:9) is the standard. X accepts any aspect ratio between 1:2.39 and 2.39:1, and resolutions from 32 × 32 px up to 1920 × 1200 px. Maximum file size is 512 MB for standard accounts.
What are X video size specs and limits?+
MP4 or MOV, H.264 video with AAC audio, up to 512 MB and 2 minutes 20 seconds on a standard account. Frame rate should be 30 or 60 fps. Premium subscriptions raise the duration and file size ceilings considerably.
How long can a video on X be?+
2 minutes 20 seconds for standard accounts, with a 512 MB file limit. Premium subscriptions raise this substantially — up to several hours and much larger files. Plan the edit around the ceiling for your account tier before exporting.
What aspect ratios does X support for video?+
Anything between 1:2.39 and 2.39:1, which covers 9:16 vertical, 1:1 square, 16:9 landscape, and cinematic widescreen. Square and portrait occupy more vertical space in the timeline, which generally means more watch time.
Why won't my video upload to X?+
The common causes are exceeding 512 MB, running longer than 2 minutes 20 seconds on a standard account, or using a codec other than H.264 with AAC audio. Re-export as MP4 with H.264 video and AAC audio at 30 or 60 fps.
