YouTube Shorts Length Checker
Drag in your Short's runtime and see how its length compares to the best-performing bands — the reach sweet spot, the crowded band to avoid, and how engagement shifts with length. Free, no login.
Drag to your Short's runtime. Shorts run up to 3:00; anything longer is a regular long-form upload.
22s lands in the 15–29s band
Weakest band

1.66%
The most crowded bucket (~37% of all Shorts) and the lowest average views. The default most creators pick — and the hardest to stand out in.
Suggestion: This is the most crowded, lowest-average-view length. If the idea can support it, extending to 45–60s roughly doubles the odds of reaching 1M+ views (0.91% vs 0.53%).
| Length | Avg like rate | 1M+ odds | The read |
|---|---|---|---|
| Under 15s | 1.05% | — | Strong on median views, but the lowest like rate of any length — quick views rarely convert into engagement. |
| 15–29sYou | 1.66% | 0.53% | The most crowded bucket (~37% of all Shorts) and the lowest average views. The default most creators pick — and the hardest to stand out in. |
| 30–44s | 1.90% | — | A clear step up in engagement from the sub-30s bands, and heading toward the sweet spot. |
| 45–59s | 2.06% | 0.91% | The highest average views of any band — about 70% likelier to reach 1M+ than the crowded 15–29s bucket. |
| 60–89s | 2.29% | — | Higher engagement still, with reach that holds up well — the upper half of the sweet spot. |
| 90s–2 min | 2.29% | — | Engagement stays high approaching the 2-minute mark, provided the idea genuinely fills the extra time. |
| 2–3 min | 2.79% | — | Highest share of 100K+ views and the strongest engagement overall — but retention gets much harder, so every second has to earn its place. |
This is a benchmark, not a promise. The figures come from a study of 331 million Shorts published in a 90-day window. They show what different lengths average across a huge sample — correlation, not a rule for your video. A tight 10s Short that nails its loop routinely beats a padded 1:00 one.
The takeaway isn't “make every Short 45s–1:30.” It's that if your idea deserves more than 30 seconds, don't cut it short just because the crowd does — the most common length is also the worst-performing one.

Set your Short's length above and this benchmarks it against a study of 331 million Shorts from a 90-day window. It tells you which performance band your runtime falls into, the average like rate for that band, and — where the data reports it — the odds of reaching a million views.
How long should a YouTube Short be? The 45–90 second sweet spot
The strongest overall performance came from 45 to 90 second Shorts. The 45–59s band had the highest average views of any length and was about 70% more likely to reach 1M+ views than the crowded 15–29s range. Yet 15–29s is where most creators publish— roughly 37% of all Shorts — and it also had the lowest average views. The most common format isn't the best one.
Engagement rises with length
Like rate climbed steadily from 1.05% under 15 seconds to 2.79% at 2–3 minutes. Quick views on very short clips don't always translate into meaningful engagement. The catch at the top end: retention gets much harder past two minutes, so every second has to earn its place — length is an opportunity, not a shortcut.
Use it as a benchmark, not a rule
This is correlation across a huge sample, not a promise for your video. A tight, well-looped 12-second Short can beat a padded 60-second one every time. The real takeaway: if your idea deserves more than 30 seconds, don't cut it short just because everyone else does.
Then win on what you actually say
Length gets you into the right band; the content decides the rest. The Video SEO Checker catches what's holding a video back, and VidHaloshows you what the top-ranking videos in your niche actually cover, where they're thin, and what viewers are still asking for.

Frequently asked questions
How long should a YouTube Short be?+
Aim for roughly 45–90 seconds if your goal is reach. In a study of 331 million Shorts, 45–59 second Shorts had the highest average views and engagement kept climbing with length up to the 3-minute cap. The most common choice — 15–29 seconds — is actually the worst-performing band. The honest rule: make it as long as your idea genuinely holds attention, and no longer.
What is the best length for a YouTube Short?+
In a study of 331 million Shorts, 45–59 second Shorts had the highest average views and were about 70% more likely to reach 1M+ views than the crowded 15–29 second range (0.91% vs 0.53%). Engagement kept rising with length all the way to the 2–3 minute cap. So the reach sweet spot sits around 45–90 seconds — but the honest answer is 'as long as your idea genuinely holds attention, and no longer.'
What are the minimum and maximum lengths for a YouTube Short?+
A YouTube Short can be as short as 1 second and up to 3 minutes long — that 3-minute cap is the maximum length. Anything longer is published as a regular long-form video instead of a Short. This checker covers the full 1-second-to-3-minute Shorts duration range.
Why do most Shorts underperform?+
Most creators publish Shorts between 15 and 29 seconds — about 37% of everything uploaded — and that bucket has the lowest average views of any length. It's the most crowded band, so it's the hardest to stand out in. The most common format isn't the best one.
Do longer Shorts get more engagement?+
In the dataset, like rate rose steadily with length: 1.05% under 15s, 1.66% at 15–29s, 1.90% at 30–44s, 2.06% at 45–59s, 2.29% at 60–89s, and 2.79% at 2–3 minutes. Quick views under 15s rarely convert into meaningful engagement.
What is the best YouTube Shorts length to go viral?+
No length guarantees a viral Short, but the odds shift with duration. In a study of 331 million Shorts, 45–59 second Shorts were about 70% more likely to reach 1M+ views than the crowded 15–29 second range (0.91% vs 0.53%), and the 2–3 minute band had the highest share of videos passing 100K+ views. Longer Shorts have a higher ceiling but are much harder to keep viewers watching, so the reliable play is 45–90 seconds with a strong hook and a clean loop — length improves your chances, but the idea and execution decide it.
How long can a YouTube Short be?+
Up to 3 minutes. Anything longer is treated as a regular long-form video rather than a Short. This checker covers the full 1-second-to-3-minute Shorts range.
Is this length the reason my Short did or didn't go viral?+
No single number decides that. This is population-level correlation across a huge sample, not causation for one video — a tight 10-second Short with a great loop routinely beats a padded 60-second one. Treat length as one lever among hook, idea and execution, not a guarantee.
