TikTok Video Size: 1080 x 1920 and the Documented Minimums
Quick answer
Upload TikTok video at 1080 x 1920 pixels in 9:16. What TikTok actually documents is a minimum of 540 x 960 at that ratio, files up to 500 MB, and durations up to 10 minutes, in MP4 or MOV among others.

What the table does not tell you
- TikTok's documented floor is 540 x 960, which is half the 1080 x 1920 everyone uploads. Both publish, but the lower one looks obviously soft against neighbouring videos in feed.
- The 500 MB ceiling is generous for 9:16 footage and easy to breach with a long export at a high bitrate. Ten minutes at 1080 x 1920 needs a sensible bitrate rather than a maximum one.
- Horizontal and square uploads are accepted but letterboxed. In a full-screen vertical feed that reads as repurposed content before anyone has processed what the video is about.
- Keep captions clear of the lower quarter and the right edge. The description, audio credit and action rail all sit there, and they vary in height between accounts.
Stop resizing the same asset five times
Crowbert formats one upload for every platform it publishes to, so a single video goes out at the right dimensions everywhere without a round trip through a design tool.
Common questions
What size should a TikTok video be?
1080 x 1920 at 9:16 in practice. TikTok documents 540 x 960 as the minimum for that ratio, so 1080 x 1920 is comfortably above the floor rather than a published requirement.
How long can a TikTok video be?
Up to 10 minutes, and files up to 500 MB, per TikTok's own specifications.
Can you post horizontal video on TikTok?
Yes. TikTok documents 16:9 at 960 x 540 or larger. It plays letterboxed inside a vertical feed, which costs most of the screen.

Where these numbers come from
Figures marked “not published by TikTok” are working conventions rather than documented specifications. Everything else comes from the documentation above.
