How Long Should a Marketing Video Be for Each Social Platform?
Keep most social marketing videos between 15 and 60 seconds, and only go longer when the platform and the goal genuinely call for it. Short works because people scroll fast and decide within a few seconds whether to keep watching. The exact sweet spot shifts by platform: a TikTok that runs 15 to 30 seconds, an Instagram Reel around 15 to 45, a LinkedIn post video up to 90 seconds, and a YouTube piece that can stretch to several minutes when the topic earns it. Below is the specific answer for each place you post, plus how to think about the choice rather than just copy a number.
How long should an Instagram video be?
Aim for 15 to 45 seconds for a Reel, and keep feed videos under 60 seconds. Instagram rewards videos that hook fast and loop, so the tighter you cut, the better a Reel tends to perform. Put your strongest visual or claim in the first two seconds before anyone has a reason to keep scrolling.
Stories are a separate case. Each card is a few seconds, so break a longer message into a short sequence rather than forcing one long clip. For a product tease or a launch, a punchy short promo video that ends on a clear call to action does more than a slow build.
How long should a TikTok video be?
Start at 15 to 30 seconds and only go longer if the story needs it. TikTok can host much longer videos, but shorter clips are easier to watch to the end, and completion matters more than raw length. A tight 20-second video that people finish beats a two-minute one they abandon at the halfway mark.
There are exceptions. Tutorials, storytelling, and behind-the-scenes content can run a minute or more if every second holds attention. The test is simple: if you can cut a line without losing meaning, cut it.
How long should a LinkedIn video be?
Keep LinkedIn videos to 30 to 90 seconds for feed posts. The audience is professional and busy, so a clear point delivered quickly lands better than a long monologue. This is a strong place for an explainer-style video that answers one question or shares one insight.
Company news, hiring pushes, and internal-facing announcements also do well here. If you are posting an update or a milestone, a focused announcement video under a minute reads as confident rather than padded.

How long should a YouTube video be?
YouTube is where longer videos belong, so plan for anything from two to ten minutes depending on the format. Unlike feed platforms, people arrive on YouTube ready to watch, often searching for something specific. A how-to, a product walkthrough, or a case study can justify several minutes as long as the pacing stays honest.
YouTube Shorts is the exception and follows the same rules as TikTok and Reels: 15 to 60 seconds, hook first. Use Shorts to pull viewers toward a longer video on the same channel.
How long should a Facebook or X (Twitter) video be?
Keep Facebook and X videos under 60 seconds, and closer to 30 for ads. Both platforms are scroll-heavy and mute by default, so design for silent viewing with captions and open with a visual that makes sense without sound. On X especially, brevity fits the pace of the feed.
For paid placements on any of these platforms, shorter is safer. A video ad built to run 15 to 30 seconds gives you room to make one point and one ask without burning budget on frames people skip.
Recommended video length by platform
| Platform | Recommended length | Best for |
|---|---|---|
| Instagram Reels | 15 to 45 seconds | Hooks, teasers, quick tips |
| Instagram feed | Under 60 seconds | Promos, single-point clips |
| TikTok | 15 to 30 seconds | Trends, quick stories |
| 30 to 90 seconds | Explainers, updates, hiring | |
| YouTube | 2 to 10 minutes | How-tos, walkthroughs, case studies |
| YouTube Shorts | 15 to 60 seconds | Discovery, channel teasers |
| Facebook / X | Under 60 seconds | Silent-friendly promos and ads |
How do you make the same video work at different lengths?
Cut one longer video down into shorter versions rather than starting from scratch each time. Film or build the full story once, then trim a 90-second LinkedIn version, a 30-second Reel, and a 15-second TikTok from the same footage. The message stays consistent and you save hours.
This is where working from templates helps. Starting from a ready-made video template means the structure and timing are already sensible, so you adjust scenes and captions instead of guessing at pacing. If you want a first draft fast, an AI video assistant that drafts from a prompt gives you a starting cut you can shorten for each platform.

Frequently asked questions
Is a shorter video always better?
No. Shorter is safer on fast-scrolling feeds, but length should match intent. Someone searching YouTube for a tutorial expects detail, while someone scrolling TikTok wants a quick payoff. Match the length to why the viewer showed up.
What is the ideal length for a video ad?
Aim for 15 to 30 seconds for most paid social ads. That gives you enough time for one clear message and one call to action without paying for frames viewers skip. Front-load the hook and the brand within the first few seconds.
Do I need captions on short social videos?
Yes, on almost every platform. Most feed videos autoplay muted, so captions carry your message when the sound is off. They also make content accessible to more viewers, which is worth doing regardless of length.
How do I decide length when I am unsure?
Start short and add time only when the content clearly needs it. Draft the tightest version that still makes sense, watch it back, and ask whether each second earns its place. If a moment drags for you, it will drag for your audience.
