How Long Should Your YouTube Videos Actually Be in 2026

Every few months someone asks us the same question in a discovery call: "What's the ideal video length?" There isn't one answer, and anyone who gives you a flat number like "8 minutes" without asking about your channel first is guessing.

What actually determines length is the job the video is doing. A tutorial that solves one specific problem can be 4 minutes and outperform a 20 minute version of the same topic, because it respects the viewer's time. A podcast clip channel or a long-form storytelling channel can run 25 to 40 minutes and hold attention the whole way, because people came in expecting a sit-down watch.

What we actually look at

When we take on a new client, the first thing we pull isn't a length target, it's the audience retention graph from their last 10 to 15 uploads. That graph tells you the truth. If you see a steep drop in the first 15 seconds, length isn't the problem, the hook is. If retention holds steady and then falls off a cliff at a specific timestamp, that's usually a pacing issue right at that point, not a sign the video was too long overall.

• Under 60 seconds: Shorts, Reels, TikToks. The job here is a single idea delivered fast, with a hook in the first second.
• 3 to 8 minutes: Most tutorial, listicle, and "how I did X" content. Long enough to deliver value, short enough that people finish it.
• 10 to 20 minutes: Vlogs, case studies, and content where the audience wants context, not just the answer.
• 20+ minutes: Podcasts, interviews, deep dives, where the audience has already opted into a longer sit.

The mistake we see most often

Creators often stretch a video to hit a length they think the algorithm rewards, and it backfires. YouTube doesn't reward long videos, it rewards watch time as a percentage of the video's length. A 6 minute video with 80% retention will usually outperform a 15 minute video with 35% retention, even though the second one technically kept people watching longer in raw seconds.

Cut for the story you're telling, not for a number you read in a YouTube growth thread.

How we approach it with clients

When we edit a channel, we treat length as an output of the edit, not an input. We cut every section for pace first: does this moment earn its place, or is it there because it felt awkward to remove? If a video naturally lands at 6 minutes after every unnecessary beat is gone, that's the right length for that video. If it naturally wants to be 14 minutes because the topic needs that room, we let it be 14 minutes.

If you're not sure what your ideal length is, look at your own retention graphs before you look at anyone else's advice, including ours. Your audience is already telling you.
