How long should a promo video be?

15 to 30 seconds for most placements. Use 9–15 seconds for Stories and Reels, 30–60 for organic social or a landing page hero, and exactly 6 or 15 seconds for non-skippable pre-roll formats.

How long should a promo video be for Instagram or TikTok?

9 to 15 seconds for Stories and Reels placements, up to 30 for an organic post. Vertical only, with the hook in the first second and captions burned in. These placements play muted by default.

Is a 60-second promo video too long?

For paid social, usually yes. For a landing page video someone chose to play, a launch announcement to an existing audience, or a product that only makes sense shown end to end, 60 seconds is fine. The test is whether every second is still making a point.

Does promo video length affect ad performance?

Less than the first three seconds and the captions do. Most paid placements optimise delivery for completion, so shorter helps, but a well-captioned 45-second promo with a strong opening will beat a weak 15-second one consistently.

Should I make multiple lengths of the same promo?

Yes. Length is the cheapest variable to test once you have found the moment. Cut 15, 30, and 45-second versions from the same source, run them against the same audience, and let the result decide rather than a benchmark.

Promo Video Length: How Long Should Each Type Be in 2026?

Every placement has a different answer, and most promos fail for reasons that have nothing to do with duration. Here are the numbers, and what actually decides whether a promo works.

Short answer

Most promo videos should be 15 to 30 seconds. Use 9–15 seconds for Stories and Reels, 15–30 for paid feed placements, 30–60 for organic social and landing page heroes, and 6 or 15 seconds exactly for pre-roll. Length matters far less than whether the first three seconds work with the sound off.

Promo video length is one of those questions with a real answer per placement and a lot of confident wrong answers in general. The short version: 15 to 30 seconds covers most of what you will make, and the promos that fail almost never fail because they were five seconds too long.

Here is the full breakdown, followed by the things that actually decide performance.

Promo video length by placement

Placement	Target length	Ceiling	Notes
Paid social (feed)	15–30 sec	60 sec	Delivery is optimised for completion; shorter usually wins
Paid social (Stories/Reels)	9–15 sec	30 sec	Vertical, hook in the first second
Organic social post	30–60 sec	90 sec	Can afford a little more context than paid
YouTube pre-roll (skippable)	15–30 sec	3 min	Make the point before the 5-second skip
YouTube bumper (non-skip)	6 sec exactly	6 sec	One idea, one visual, one word of CTA
Landing page hero	30–60 sec	90 sec	Autoplay muted, loops cleanly, captions burned in
Email	20–40 sec	60 sec	Static thumbnail linking out, never an embed
Event / webinar promo	20–45 sec	60 sec	Date and registration link on screen for 3+ sec
Product launch announcement	30–60 sec	2 min	The one case where a longer promo regularly works
App store / product page	15–30 sec	30 sec	Assume it plays muted and on loop

The first three seconds decide more than the total length

A 15-second promo with a weak opening performs worse than a 45-second promo with a strong one. Duration influences completion rate; the opening decides whether there is anything to complete.

Three practical rules for the opening, all of which matter more than shaving seconds off the end:

Something must visibly change within the first second. Motion, a cut, text appearing. A static frame is a scroll.
No logo animation at the front. Put branding in the corner throughout and the logo at the end.
The claim goes first, the context second: lead with "four minutes instead of an afternoon", then explain. Never the reverse.

Captions are a length multiplier

The majority of feed video plays muted. A promo that only works with sound is effectively a silent film with an unreadable plot, and no amount of trimming fixes that.

Burn captions in rather than relying on platform auto-captions, which vary by platform and often disappear on reshares. Keep them large, high-contrast, and positioned clear of the platform UI: the bottom fifth of a vertical video is usually covered by buttons and account names.

The practical effect is that a well-captioned 45-second promo often holds attention better than an uncaptioned 20-second one, which is why "make it shorter" is frequently the wrong fix for a promo that is underperforming.

Hyperclip renders every length and aspect ratio you need from the same source recording, with captions burned in, so testing a 15-second cut against a 30-second cut costs you one extra request.

Cut your promo to length

How length changes by funnel stage

The other variable that beats placement: how much the viewer already knows. A cold audience needs brevity because they have no reason to stay. A warm audience will give you longer because they have already decided the topic is relevant.

Audience	Length	What the promo should do
Cold audience, never heard of you	9–15 sec	One surprising moment. Nothing else.
Warm audience, knows the category	15–30 sec	Show one capability doing one job
Retargeting: visited, did not convert	20–40 sec	Answer the objection that stopped them
Bottom of funnel, reached pricing	9–20 sec	The offer, stated plainly, with one action

Note that the shortest promos sit at both ends. Cold audiences are short because attention is scarce; bottom-of-funnel is short because everything has already been explained.

What to cut when you are over length

Cut structurally, not evenly. Speeding the whole thing up or trimming a little from every section makes a promo feel rushed without making it shorter in any way that helps.

The intro. Almost every over-length promo has 3–8 seconds of preamble that can go entirely.
The second feature. A promo covers one thing.
Transitions between sections. Cut hard instead. It reads as confident.
The setup sentence before the hook. Start on the hook itself.
The end card, down to one line and one action, but hold it for at least two seconds.

Nobody ever skipped a promo because it was too short.

When a longer promo is right

Three genuine exceptions to the 15–30 second default:

A launch announcement to an existing audience, where people have opted in and want the detail.
A product where the value is only visible in sequence. A workflow that has to be shown end to end to make sense.
A landing page video that someone chose to play. That is not a promo interrupting anything; it is content they requested.

Outside those, if you are arguing for 90 seconds, the more likely explanation is that the promo has not decided what its single point is.

Test length instead of guessing it

Every table in this article is a starting point, not a rule. The distribution of your audience, your product, and your placement mix will move the right answer around. Length is also the cheapest variable to test, the same source footage cut at 15, 30, and 45 seconds costs almost nothing extra once you have found the moment.

Cut three lengths of your best promo, run them against the same audience, and you will know more about your specific case in a week than any benchmark can tell you.
