How long should a video be?

As long as the idea needs, and no longer. The twelve films on our case pages whose length we give run from five to twenty-four seconds.

The platforms take longer videos than they used to. That doesn’t mean a business should fill the time. Here are the limits, the lengths of our films, and how to decide.

How long a short video should be: the short answer

A short video should be as long as its idea needs and not a second longer. No platform publishes a best length, and each now takes far longer videos than a business usually needs. The question isn’t how much time the app allows; it’s how long the film can hold a stranger. For the films on our case pages, that was five to twenty-four seconds.

The platforms’ limits

PlatformWhat it says
InstagramFrom 21 January 2025, “reels up to 3 minutes will be eligible to be seen by non-followers in places like the Reels tab and Explore”; before, only reels up to 90 seconds were. The post introduced 3-minute reels in the Reels editor for creators in the United States first
YouTube ShortsA square or vertical video up to three minutes, uploaded on or after 15 October 2024, “will be categorized as Shorts”
TikTok“Videos you record in TikTok can be up to 10 minutes long. Videos you upload in TikTok can be up to 60 minutes long”
Facebook“While you can share any length videos on Facebook, avoid super short videos that offer viewers little value”

A limit is room to use when the idea needs it. Most ideas we film need far less. A film meant for all four platforms is safest inside the tightest of these lines: vertical, and three minutes or less, so it counts as a YouTube Short and can be recommended to non-followers on Instagram.

Three of these went viral: Icon’s seven-second “My POV” and eleven-second leg position, and Da.Si.Mar’s twenty-four-second wrap. None was long, and none was the shortest. Each was as long as its idea.

Let the idea set the length

  • A joke needs a setup and a punchline, often in under ten seconds.
  • A process, like food made start to finish, needs every step: twenty seconds or more.
  • Voices, like a line of people answering a question, need time for each answer.
  • An explanation, like a treatment step by step or an estimate explained, can run longer, if every step is worth seeing.

Short, but not too short

Meta’s advice against “super short videos that offer viewers little value” is about value, not seconds. A seven-second joke that lands offers plenty; a five-second clip of a storefront with a logo offers nothing. TikTok, for its part, names finishing “a longer video from beginning to end” as a strong signal of interest (TikTok Newsroom). Long is fine when people stay for all of it. The test for any length is whether people watch to the end.

Music on longer Shorts

One rule changes at one minute on YouTube: “Any Short that is over one minute in duration with an active copyright claim of any type, including manual claims, will be blocked globally on YouTube” (YouTube Help). A long Short with a popular song under it can be blocked worldwide. Keep longer films to sound you recorded yourself, with no music in the background, or music you have the rights to.

What to cut

The intro, the logo, the walk to the counter, a second take of the same shot. If a stranger would skip it, cut it. “How to edit a short video” covers the edit.

Check the length against the numbers

Instagram defines a reel’s average watch time as the watch time “divided by the number of initial views” (Instagram Help Center). Divide it by the film’s length to compare films of different lengths. It’s an average, with replays and early exits both in it, so it can’t say where anyone stopped.

For example, round numbers: a 30-second reel with an average watch time of 9 seconds averages 9 ÷ 30 = 0.3 of its length. A 10-second reel averaging 8 seconds averages 8 ÷ 10 = 0.8. If your longer films keep showing the first pattern, try them shorter, or open them stronger.

Short invites a replay

A short film that ends on its payoff gets watched again, and replays count: YouTube counts every start or replay of a Short (YouTube Help), and Instagram counts each time a reel starts to play or replay (Instagram Help Center).

Common mistakes

  • Filling the time because the app allows three minutes.
  • Cutting a process short so the best step never appears.
  • A long film with someone else’s song under it.
  • Judging length by views alone, instead of how much of it people watched.
  • A slow first five seconds in a long film, where it hurts most.

Questions owners ask

How long should an Instagram Reel be for a business?

As long as the idea needs. Instagram can recommend reels up to three minutes long, yet the twelve films on our case pages with a length given run from five to twenty-four seconds.

What is the best length for a TikTok?

There’s no official best length. TikTok takes recordings up to 10 minutes and uploads up to 60. Start short, and go longer only when every second earns its place.

How long can a YouTube Short be?

Up to three minutes, for a square or vertical video uploaded on or after 15 October 2024. Over one minute, a Short with an active copyright claim is blocked worldwide.

Can a video be too short?

If it offers nothing. Meta advises against super short videos that offer viewers little value. A seven-second joke that lands isn’t one of them.
