Ratio, pixels, and the 10 GB cap

TikTok video size

TikTok's web uploader asks for 720×1280 or higher and accepts MP4 or WebM under 10 GB, up to 30 minutes. The size people mean when they search this is the phone size: 1080×1920, 9:16.

Ads are a tighter box (at least 540×960, 9:16, 500 MB, 516 kbps). The grid uses the web-upload numbers for pass/fail and mentions the ads safe zone separately.

Drop a clip

MP4, MOV, WebM, or a thumbnail. Duration, resolution, aspect, fps, codec, and file size are read here. Nothing is uploaded.

What to do with it

  • 1080×1920 is the export. 720×1280 passes the floor and warns for the recommended frame.
  • A 1920×1080 gameplay clip is a high resolution and the wrong shape. The aspect check warns; the cover preview shows the crop.
  • File size almost never fails the 10 GB web cap. The 300 MB and 512 MB buttons exist for Instagram's API and free X.
  • H.264, HEVC, VP8, and VP9 are the codecs cited for the API. The web page itself only names the container.

TikTok specs

Web uploads through TikTok Studio run up to 30 minutes. 720×1280 is the published floor and 1080×1920 is the size creators should actually export.

Official safe zone, 1080×1920

240 top / 660 bottom / 120 left / 120 right

Scaled ×1.5 from TikTok's 720×1280 in-feed template (top 160, bottom 440, sides 80). The right action column is an approximate cited range of about 180–300 px wide starting near y=840; this overlay draws the wide end, 300×420.

Measured safe zone, 1080×1920

200 top / 500 bottom / 0 left / 250 right

Organic write-ups disagree: top 130–200, bottom 370–500, right rail 140–250. Measured mode draws the high end of that range. A left inset is not consistently published, so it stays 0. See also https://www.socialync.io/tools/safe-zones.
