The short answer

Free accounts: 2 minutes 20 seconds. Premium: up to 4 hours.

In the X app, a free account can post a video of up to 2 minutes 20 seconds (140 seconds) and 512 MB. Any X Premium tier, Basic included, allows far longer uploads on x.com and iOS. X's video help page says under 4 hours and 16 GB, at 1080p up to 2 hours and 720p beyond; its Premium page says about 3 hours and 8 GB.

Schedulers post through X's API, where X's docs list 20 minutes and 8 GB for standard accounts and 125 minutes and 16 GB for Premium. OmniSocials allows 125 minutes for Premium and Premium+ accounts and holds other accounts to 2 minutes 20 seconds, the length X's app allows. X gives no ideal length for posts; its ads guide recommends 15 seconds or less for video ads.

Video specs

What a video must fit, in the app and via schedulers. The API's rules are stricter.

What changed

What changed for video length. The API now spells out its limits.

  1. Sep 2026

    API video limits by account

    X's developer docs now list post video limits by account: up to 20 minutes and 8 GB by default, 125 minutes and 16 GB for Premium or verified accounts. Source

  2. Jan 2025

    New API media upload

    X launched new media upload endpoints in its v2 API, which schedulers use to send video in chunks. Dedicated chunked upload endpoints followed in April 2025. Source

Tips

Pick the right length. Your plan sets the limit.

  1. Trim to 2:20 on a free account

    Free accounts stop at 140 seconds in the app. Cut a highlight, or post the full video where your plan allows it.

  2. Long videos need Premium

    Every Premium tier, Basic included, allows long uploads on x.com and iOS. Over 2 hours, X drops to 720p.

  3. Keep ads short

    X's ads guide recommends 15 seconds or less for video ads and supports up to 2:20.

  4. Export H.264 MP4

    Export MP4 or MOV with H.264 video and AAC audio, the format X's API asks for.

  5. Add captions

    On iOS and Android, X shows captions automatically in the timeline when a video has them.

  6. Add timestamps to long videos

    Times like 1:30 in the post become clickable on iOS, up to 50 per post, so viewers can jump ahead.

Other platforms

The same guide for every network. Each one has its own rules.

How we built this guide. Checked on October 17, 2026.

The limits come from X's Help Center, X's developer docs and X's ads guide, read on October 17, 2026. X's video help page and its Premium page give different Premium limits, so the page shows both. X publishes no ideal length for posts, and we found no 2025 or 2026 study of X video length, so the ruler marks no best length.
