Best video length for TikTok, Reels and YouTube Shorts (2026)

There is no official best video length for TikTok, Instagram Reels or YouTube Shorts. None of the three platforms publishes a target, and the "ideal length" numbers you see in guides come from vendors' own samples, which disagree with each other. What the platforms do publish is a maximum, plus a few rules that change how longer clips are treated. This guide lists those limits from each platform's own help pages, then gives you a practical way to decide how long a clip should be: cut to the payoff, check the word count, and stop.

The short answer

The best length for a short clip is the shortest version that still delivers the full payoff. A one-line tip might need 15 seconds. A story with a setup, a turn and a punchline might need 70. Padding a clip to hit a number makes it worse, and so does cutting it before the point lands.

So decide length clip by clip, not platform by platform. Then check the result against the platform's limits below.

Maximum video lengths by platform (checked October 2026)

These limits change often, and third-party guides quote different numbers for the same app. Everything in this table comes from the platform's own help pages or newsroom, checked in October 2026. If your app shows something different, trust the app.

YouTube Shorts details

YouTube raised the Shorts limit from 60 seconds to three minutes for videos uploaded on or after 15 October 2024. A video only counts as a Short if it is square or vertical. A 16:9 video of the same length is a regular long-form upload.

Two rules on the same YouTube help page matter if you go past a minute. A Short longer than one minute with an active copyright claim of any kind is blocked worldwide until the claim is resolved. And most songs from YouTube's library can be used for up to 90 seconds of a three-minute Short, with some limited to 60 or 30 seconds. If your clip uses music or footage you don't own, keep it under a minute or clear the rights first.

Instagram Reels details

Instagram's help page says you can record and edit Reels up to 20 minutes, but Reels over three minutes won't be recommended to new audiences. In practice that makes three minutes the ceiling for any Reel you want people who don't follow you to see. Longer Reels still reach your existing followers.

TikTok details

TikTok has changed its limits several times, and it sets them differently for recording in the app and for uploading a finished file. They can also differ by account and region. We couldn't confirm a single current figure on TikTok's own help pages in October 2026, so we don't print one here. Open the upload screen in the app: it shows what your account can post. For short clips cut from a longer video this rarely matters, because you will almost always be far under any limit.

LinkedIn, X and Facebook

LinkedIn accepts videos from 3 seconds (2 in the mobile app) up to 15 minutes. X allows 140 seconds unless you pay for a subscription. Facebook removed length and format restrictions on Reels in June 2025, when it started sharing all new videos as Reels.

Why there's no official "best" length

Search for the best TikTok length and you'll find confident ranges down to the second. Treat them with care. They usually come from a tool vendor's own sample of videos, measured in different ways and at different times, and the ranges disagree. None of them is published by TikTok, Instagram or YouTube.

The only official signal in the table above is Instagram's three-minute line for recommendations. Everything else is a ceiling, not a target.

What you can control is whether each second of your clip earns its place. A clip that is longer than its content feels slow. A clip that is shorter than its content cuts off the reason anyone would share it. That is a property of the clip, not the platform.

How to choose a length for a clip

Here is the method we use. It works whether you're cutting a podcast, a stream, a webinar or a YouTube video you already published.

1. Find the payoff first

Start at the end. What is the line, reveal or result that makes this moment worth posting? It might be the punchline of a story, the answer to a question, the surprising number, or the moment the play works. Mark where it finishes. If you can't name a payoff, the moment probably isn't a clip yet.

2. Find the earliest line that sets it up

Now scrub backward from the payoff to the first sentence a stranger needs in order to understand it. Not the start of the topic, not the host's intro, just the first line that makes the payoff make sense. That line is your start, and often your hook. Our guide to short-form video hooks covers how to pick it.

3. Cut what sits between

Between that start and the payoff, remove anything a stranger doesn't need: long pauses, filler words, repeated points, side stories, "as I said earlier". Read the transcript and ask of each sentence, "would the payoff still land without this?" If yes, cut it.

4. Measure it in words

Count the words that are left. A typical conversational pace is somewhere around 150 words a minute, but speakers vary a lot, so time your own. At 150 words a minute:

The free video length calculator does this for any script or transcript at your own pace, and shows how many words fit 15, 30 and 60-second clips.

5. Check the captions can be read

If the clip is dense with words, the captions may flash by too fast. Netflix's English timed text style guide allows up to 20 characters per second for adult programs and 17 for children's. On a phone, while also watching the picture, slower is kinder. If your captions run faster than that, the clip is trying to say too much: cut a sentence rather than speeding the captions up. The calculator above checks caption files too, and the caption generator turns a script into SRT or VTT. For the full workflow, see how to add captions to videos.

6. Check the platform ceiling

Only now look at the table. If the clip is under a minute, it fits everywhere. Between one and three minutes, it fits Shorts (watch the copyright rule), Reels and LinkedIn, but not X without a subscription. Over three minutes, it is no longer a Short, and Instagram won't recommend it to new viewers. At that point, ask whether it is really two clips.

7. Watch it once on a phone, sound off

Play the clip on a phone with the sound off. Does the first second make you want the next one? Does it end on the payoff, not two sentences after it? Trim the tail if the speaker keeps talking after the point lands. Ending on the payoff is almost always better than a tidy wrap-up.

Length by type of clip

Instead of one number per platform, think about what the clip is doing.

• A single tip or fact. One claim, one reason. These often fit in 40 to 75 words. If yours runs longer, you may be explaining two tips.
• A story. Setup, turn, payoff. Stories need their setup, so they run longer. Don't cut the setup to save time, or the punchline has nothing to land on.
• A how-to. Each step needs to be shown or said. Count the steps, give each one room, and resist adding a long intro.
• A reaction or highlight. In gaming and live streams, the moment itself might be ten seconds. Add only enough lead-in for a stranger to see what's at stake.
• An argument or opinion. The claim and the strongest reason. Leave the caveats for the full episode.

For podcasts specifically, our guide on how to make podcast clips walks through picking moments from a long conversation.

Platform notes

TikTok

TikTok shows a wide range of lengths. Use the method above and let the content decide. Keep the start tight, because the first line is doing the most work.

Instagram Reels

Under three minutes if you want reach beyond your followers. The Reels feed and your profile grid crop the frame differently, so check the cover too. See Instagram Reels specs.

YouTube Shorts

Up to three minutes, square or vertical. If you're cutting from your own long YouTube video, see how to turn YouTube videos into Shorts, which also covers YouTube's built-in "Edit into a Short" tool. Platform details are on our YouTube Shorts page.

LinkedIn

LinkedIn allows up to 15 minutes, but a clip from a webinar or interview still works best when it makes one point. The LinkedIn page covers sizes for the feed.

X

Without a subscription you have 140 seconds. That is plenty for most clips, but check before exporting a long story.

Should you post the same clip everywhere?

You can. A clip under a minute fits every platform in the table. The things that differ are the overlays and crops, not the length. Make sure your captions and on-screen text sit clear of each app's buttons: our guide to vertical video sizes and safe zones has the numbers.

If a clip runs between one and three minutes, cut a shorter version for X, or post the long one only where it fits.

Common mistakes

• Padding to hit a target. If someone told you 30 seconds is best and your moment is 18, post 18.
• Cutting before the payoff. The most common way a clip fails. Always check the last line.
• Keeping the warm-up. "So, yeah, I think the thing is..." is not a start. Begin on the first line with content.
• Ending after the point. Stop on the payoff. Don't let the speaker wind down on camera.
• Ignoring rights over one minute on Shorts. A claim on a Short longer than a minute blocks it worldwide.
• Trusting a number you can't source. Limits change. Check the platform's help page, or the app itself, before you plan a series around one.

The takeaway

Platforms set ceilings, not targets. Find the payoff, start on the first line a stranger needs, cut everything in between that doesn't serve the payoff, then check the result against the limits above. The length you end up with is the right one for that clip.
