X (Twitter) Video Length Limit (2026)

On a free X (formerly Twitter) account, a single video can run up to 2 minutes 20 seconds — 140 seconds — with a file size cap around 512 MB. That free ceiling has been in place for years and is the number most creators actually bump into. If you subscribe to X Premium, the limit jumps dramatically: reports in 2026 put it in the range of a couple of hours of video, though the precise figure depends on your subscription tier, the device you upload from, and which version of the app you are using. Because X changes these allowances without much announcement, the value below is a snapshot — always confirm the current cap on the upload screen before you plan a long edit.

The free limit: 140 seconds and 512 MB

For anyone posting without a paid subscription, the working numbers are 140 seconds of duration and roughly 512 MB of file size. Hit either ceiling and X will refuse the upload or force you to trim. In practice the length limit is what stops most people first, because 140 seconds is short for anything beyond a clip, a reaction, or a teaser. The file-size cap matters more for high-bitrate exports: a short but very high-quality clip can exceed 512 MB even when it is well under two and a half minutes, so if a short video is rejected, your bitrate or resolution is usually the culprit rather than the length.

It is worth knowing that these two limits are enforced separately. A 139-second clip that was exported at an enormous bitrate can fail on size, and a tiny 10-second clip is obviously fine on both counts. If you are repeatedly running into the wall, the practical move is to tighten your edit toward the 140-second mark and keep your export sensible rather than maxing out quality settings you do not need for a feed that compresses everything anyway.

What X Premium changes

Paying for X Premium is the official route to longer video. The headline figure reported through 2026 is measured in hours rather than minutes, which is why Premium is popular with people posting long-form interviews, streams, and video essays directly to the platform instead of linking out. The catch is that the exact allowance is inconsistent across sources: some list roughly two hours, others three or four, and the ceiling can differ between the web uploader, iOS, and Android. Higher Premium tiers generally unlock more, and the file-size allowance rises well above the free 512 MB.

Because of that spread, we deliberately avoid asserting one hard Premium number here. If a long upload is central to your plan, the only trustworthy answer is the one your own account shows when you try it — subscribe, open the composer, and watch what the uploader accepts.

Why the numbers you read online disagree

Search for this question and you will find blogs quoting 140 seconds, two hours, four hours, 8 GB, and 16 GB, often on the same page. Several things cause that: X ships changes quietly, the limits differ by platform and tier, and a lot of third-party pages simply copy each other without re-checking. There is even conflicting chatter about separate limits for uploads made through the developer API versus the consumer app. None of this means the writers are careless — it means the spec genuinely moves and fragments. Our guidance is to trust the free 140-second figure (it is stable) and to verify any Premium or API figure against X’s own Help Center or the upload screen rather than any blog, including this one.

How to check your real limit before you film

You do not need to guess. Open the X app or web composer, attach the longest clip you have, and see what happens: the uploader will either accept it, show a trimmer, or tell you it is too long. Doing this before you shoot or finish an edit saves you from cutting a finished piece down later. If you plan to post a long video on Premium, run a short test upload of a few minutes first to confirm your account tier behaves the way you expect on the device you will actually use.

File size, resolution, and format that upload cleanly

Length is only half the story; how you export decides whether the clip is accepted and how good it looks afterward. X re-encodes uploads, so there is little point feeding it an oversized master. A reliable recipe is MP4 with H.264 video and AAC audio, 1080p or 720p, at a moderate bitrate. For vertical clips, keep the framing tidy because X displays video in-feed where the usable area is limited. If you are preparing the same footage for multiple networks, our best export settings for Instagram Reels guide covers a vertical recipe that travels well across platforms, and the broader aspect ratio calculator helps you confirm your frame before you export.

Does length affect reach on X?

The cap is a hard limit, but the practical length is a creative decision. X’s feed rewards videos that hold attention, and a tight clip that keeps people watching to the end generally outperforms a long one they abandon halfway. That is one reason the 140-second free ceiling is less of a handicap than it looks: for most feed content, you would not want to run much longer anyway. If you have Premium and the ability to post long video, reserve that length for content people actively seek out — interviews, full talks, tutorials — rather than stretching a short idea to fill the allowance. Front-load the hook in the first few seconds regardless of length, because that is where viewers decide whether to keep watching, and add captions, since a large share of X video is watched with the sound off.

Vertical, square, or landscape on X

Aspect ratio does not change the length limit, but it changes how much screen your video claims in the feed and therefore how it lands. Square (1:1) and vertical (9:16) clips occupy more vertical space and tend to stand out on mobile, where most of X’s audience is. Landscape (16:9) suits content that is genuinely widescreen, such as gameplay or cinematic footage. Whatever ratio you choose, keep essential action and any on-screen text away from the extreme edges, because the in-feed player and overlaid interface can crop or cover them. If you are building a profile around video, getting the surrounding visuals right matters too — our X header photo size guide covers the banner that frames your page.

What to do when your video is too long

If a clip exceeds the free 140-second cap and Premium is not an option, you have three practical choices. Trim the edit down to the strongest 140 seconds — usually the best outcome, because short native video performs well. Split a longer piece into a thread of sequential clips, which keeps everything on-platform and lets viewers watch in order. Or post a short, compelling teaser and link to the full video hosted elsewhere, accepting that off-platform links tend to get less reach. Which you choose depends on whether watch-through or completeness matters more for that particular post.

How X compares to other networks

X’s free limit sits in the middle of the pack. It is far longer than a quick status clip but much shorter than what long-form platforms allow. If you are deciding where a given video belongs, it helps to know the neighbours: see our breakdowns of the YouTube video length limit, the TikTok video length limit, and the Instagram video length limit. A two-minute clip that feels cramped on X may be a perfect fit as a Short or a Reel, and the same master can often be repurposed across all of them with only a frame change.

Bottom line

Plan around 140 seconds and 512 MB if you are free, and treat Premium’s multi-hour allowance as real but imprecise — confirm the exact figure at upload for your tier and device. The platform moves these limits without fanfare, so the upload screen is always a better source than yesterday’s article.
