Video content is a must-have for any marketing campaign. But how long should a social media video be?
It can be hard to nail the runtime, and there’s no universal answer: each platform has its own sweet spot. Read on to learn the best possible video lengths for each social network.
Most platforms land somewhere between 15 and 60 seconds, but the right length depends entirely on the platform (and the format within it). Here’s the recommended and maximum video length for every major platform at a glance:
| Platform | Recommended length | Maximum length |
| Instagram Reel | 15-45 seconds | 20 min |
| Instagram in-feed video | 15-60 seconds | 60 min (desktop) / 15 min (mobile) |
| Instagram video ad | 10-15 seconds | 90 seconds if boosting a Reel |
| Instagram Story | 5-15 seconds per slide | 60 seconds |
| TikTok video | 20-35 seconds | 10 min (in-app) / 60 min (upload) |
| TikTok video ad | 9-15 seconds | 60 seconds |
| YouTube video | 6-12 min | 15 min (default) / 12 hr (verified) |
| YouTube Short | 15-45 seconds | 3 min |
| Facebook Reel | 15-30 seconds | No length restrictions; 90 seconds if boosting |
| Facebook in-feed video | 30-60 seconds | 241 min (~4 hr) |
| Facebook Story | 5-15 seconds per frame | 120 seconds |
| Facebook video ad | 6-15 seconds | 241 min (~4 hr) |
| X (Twitter) | 15-45 seconds | 140 seconds (free accounts) / 4 hr (Premium accounts) |
| 30-60 seconds | 10 min | |
| Snapchat | 5-15 seconds | 60 seconds |
| 10-30 seconds | 5 min |
How long should an Instagram video be?
Instagram Reels do best at 15 to 45 seconds, Stories at 5 to 15 seconds per slide, in-feed videos at 15 to 60 seconds, and video ads at 10 to 15 seconds. Here’s how each format breaks down.
How long should an Instagram Reel be?
The best length for Instagram Reels is 15 to 45 seconds.
You can make Reels up to 20 minutes long, but just because you can doesn’t mean you should. Even Adam Mosseri, Head of Instagram, believes short is better: “There’s no perfect length for a Reel, but generally, we recommend Reels under 3 minutes because Instagram is focused on short video,” he shared.
Ultimately, the real work happens in the first three seconds, says Mosseri. That’s the window where someone decides to stick around or keep scrolling. So nail the opening, and the rest of your Reel has a fighting chance.
Pro tip 💡: Open your Instagram Insights and pull up the Retention chart. It shows the percentage of viewers still watching at each second of your Reel, so you can pinpoint the exact moment people start dropping off. The culprit might be a slow opening, a clunky transition, or an inconsistent frame rate. Once you spot where you’re losing people, you know exactly what to change for next time.
How long should an Instagram in-feed video be?
The best length for an Instagram feed video is 15 to 60 seconds.
You can go up to 60 minutes on desktop or 15 minutes on mobile, but in-feed videos are fighting Reels for the same attention. So, a minute or less is plenty for most posts.
How long should an Instagram Story be?
The best length for an Instagram Story is 5 to 15 seconds per slide. Stories are tap-through content, so people are moving fast. The goal is to make one clear point per frame, not cram in a whole commercial.
Instagram Story videos can be as long as 60 seconds per clip. If you post anything longer, Instagram automatically splits it into separate clips you can trim.
If you need to post multiple slides, don’t exceed 7 (and really, 3 slides is plenty). Be sure to include a call-to-action or other relevant info on each slide, and stay economical with your messaging.
How long should an Instagram video ad be?
The best length for an Instagram video ad is 10 to 15 seconds, with room to stretch to 30.
Because Instagram ads are usually interruptive and skippable, the ad needs to earn attention fast. That said, longer ads aren’t off the table. They just need a reason to exist.
For example, if you’re targeting people who already know your brand — like past website visitors or email subscribers — you can test a longer video ad. Around 15 to 45 seconds can work well for product demos, testimonials, case studies, or tutorials.
One important caveat: If you’re boosting an Instagram Reel, it must be under 90 seconds.
How long should a TikTok video be?
The best TikTok video length is 20 to 35 seconds. That gives you enough room to hook viewers, make your point, and wrap up before attention drops.
Technically, TikTok videos can be much longer. You can record videos up to 10 minutes in the TikTok app or upload videos up to 60 minutes. But you should still aim for brevity.
That’s because length isn’t what wins. Pacing is. For example, a 25-second video watched all the way through beats a 2-minute clip people quit halfway.
The right length really comes down to what you’re making. Use these ranges as a starting point:
- Short (15–30 sec): Ideal for trends, hot takes, and quick reactions.
- Medium (30–60 sec): Ideal for tutorials and product demos.
- Longer (1–3+ min): Ideal for storytelling or educational content.
Whatever range you land in, the same rule applies: Go only as long as you can keep people watching.
How long should a TikTok ad be?
The best length for a TikTok ad is 9 to 15 seconds. TikTok’s ad policy allows anywhere from 5 to 60 seconds, so 60 seconds is the hard cap. But just because you have a full minute doesn’t mean you should use it. The first few seconds decide whether someone watches or scrolls, so make your point fast and keep it tight.
How long should a YouTube video be?
The best length for a standard YouTube video is 6 to 12 minutes. That said, YouTube has plenty of room for longer content. By default, accounts can upload videos up to 15 minutes, while verified accounts can upload longer videos, up to 12 hours or 256 GB.
But long for the sake of long doesn’t work. Only stretch a video out when it has the structure to carry it — think chapters, clear sections, useful examples, and a reason to keep watching.
Your ideal length also depends on your monetization goals. If you’re in the YouTube Partner Program, videos that are 8 minutes or longer can include mid-roll video ads. That’s a good target to hit, but don’t stretch a 2-minute idea into an 8-minute video just for ads. Weak retention can hurt both your views and your earnings.
Genre matters, too. According to a video from YouTube’s Creators channel, some genres demand more runtime, like gaming. Others are better kept short, like simple tutorials, quick answers, and basic how-tos. As the YouTube team puts it, “No one wants to watch a 15-minute video on how to restart your Mac.”
Take a look at competitors in your genre. How long are their videos? Can you spot a connection between views and video length?
Key takeaway: Aim for 6 to 12 minutes as a starting point, but let the topic, format, and audience decide. Go longer only when the content earns it.
How long should a YouTube Short be?
The best length for a YouTube Short is 15 to 45 seconds. That said, YouTube Shorts can be up to 3 minutes long, so you have more runway for bigger ideas.
Shorts are built for quick viewing, so retention matters. The YouTube algorithm pays close attention to watch time, so the Shorts that grab attention early and hold it tend to have the best shot at being recommended.
How long should a YouTube video ad be?
It depends on the ad format, but YouTube video ads run short, from 6 seconds up to a few minutes. Here’s the quick version:
- Bumper ads: 6 seconds or less
- Non-skippable in-stream ads: 7 to 15 seconds (up to 30 for connected TV)
- Skippable in-stream ads: 12 seconds to 3 minutes, with 30 to 60 seconds as the sweet spot
Bumper video ads are the shortest of the bunch. They’re built for quick, repeatable brand recall, so you get six seconds to land one clear idea.
Non-skippable video ads play before, during, or after a video, including mid-roll spots partway through longer content.
Skippable in-stream ads (the kind viewers can skip after 5 seconds) give you the most room, but you still have to hook people before the skip button wins.
Whatever the format, treat the opening like it’s the only part anyone will see, because for a lot of viewers, it is.
How long should a Facebook video be?
Facebook Reels do best at 15 to 45 seconds, in-feed videos at 30 to 60 seconds, Stories at 5 to 15 seconds per slide, and ads at 6 to 15 seconds. Here’s how each format breaks down.
How long should a Facebook Reel be?
The best length for a Facebook Reel is 15 to 30 seconds. For more detailed ideas, you can stretch to 30 to 60 seconds, but only if the content has enough momentum to keep people watching.
Meta is also changing how Facebook video works: All new Facebook videos are being shared as Reels, and Facebook Reels will no longer have length or format restrictions as the update rolls out. So, there may not be one neat universal max the way there used to be.
One important caveat: Boosting only works on Facebook Reels that are 90 seconds or shorter. So if Reels are part of a paid push, keep it under that limit.
How long should a Facebook in-feed video be?
The best length for a Facebook in-feed video is 30 to 60 seconds. At most, in-feed videos can run up to 241 minutes, or just over 4 hours. But that’s a ceiling, not a goal
For simple announcements, promotions, or product highlights, 30 seconds may be plenty. For explainers, testimonials, tutorials, or videos that need more context, 45 to 60 seconds can work well.
How long should a Facebook Story be?
The optimal length for a Facebook Story is 5 to 15 seconds per frame. The max is 120 seconds.
Stories disappear after 24 hours, so they’re built for quick, in-the-moment updates. Keep each frame to one clear idea and let the sequence do the storytelling.
How long should a Facebook video ad be?
The optimal length for a Facebook video ad is 6 to 15 seconds. The max is 241 minutes (about 4 hours), but that ceiling has nothing to do with what actually performs.
Facebook’s own advice is to use those first few seconds wisely: Bring your story to life fast and get your brand or product on screen early, before anyone has a chance to scroll. The platform is clear that length matters far less than telling a tight, cohesive story.
A simple rule of thumb: Keep awareness ads to 6 to 15 seconds, and give product demos or offers a little more room at 15 to 30 seconds.
How long should an X (Twitter) video be?
The optimal length for an X video is 15 to 45 seconds.
As of 2026, free accounts can post videos up to 140 seconds, while X Premium subscribers can upload clips as long as 4 hours. But on a platform built for fast scrolling and even faster opinions, the shorter end almost always wins.
How long you go depends on the type of post:
- 6 to 20 seconds for punchy moments, hot takes, and sports or news clips.
- 30 to 90 seconds for explainers and thought-leadership.
- 2 minutes or more for podcast clips, demos, and commentary, where people have already opted in for depth.
Whatever the length, the post copy above your video does a lot of the heavy lifting on X. A sharp line of text can be the difference between a scroll and a play.
How long should a LinkedIn video be?
The optimal length for a LinkedIn video is 30 to 60 seconds. Native video can technically run up to 10 minutes, but unless you want your post to feel like an endless board meeting, you’ll want to stay short of that.
The data backs it up. LinkedIn found that videos 30 seconds or shorter see a 200% lift in completion rates, meaning people actually watch to the end instead of clicking away. It’s a professional audience that values its time, so the faster you get to the point, the better your odds of holding it.
If you’re running LinkedIn video ads, the platform recommends staying in the 15-to-30-second range. Save the longer video formats for when you have a genuinely meaty story to tell and an audience that’s already invested.
How long should a Snapchat video be?
The optimal length for a Snapchat video is 5 to 15 seconds. The max is 60 seconds, and that cap is consistent across the app, covering direct Snaps to friends, videos posted to your Snap Story, and video messages in Chat.
Snapchat runs on fast, casual, swipe-through energy, so it rewards content that feels spontaneous over anything polished or drawn out. The shorter and more in-the-moment your video feels, the more at home it is here.
In other words, save the high production value for other platforms and let Snapchat be the candid one.
How long should a Pinterest video be?
The optimal length for a Pinterest video is 10 to 30 seconds. The max is 5 minutes for a Video Pin.
Pinterest is the rare platform where a little extra length can work in your favor, because people arrive with intent. In fact, Pinterest users are nearly 90% more likely to say they’re ready to shop than users on other platforms.
That intent gives your video content room to breathe. A tutorial or walkthrough can run longer than it would on a feed built for entertainment, as long as it’s genuinely helpful.
Save the extra seconds for recipe walkthroughs, DIY projects, routines, design processes, or product how-tos, where every step earns its place. For everything else, keep it tight and let the Pin do its job fast.
Social media video best practices
No matter the platform or the length you land on, a handful of habits make every social video perform better. Here are a few best practices to consider:
- Add captions or on-screen text, since many people watch without sound.
- Be mindful of video specs, which vary by platform. Vertical videos suit TikTok, Reels, Shorts, and Stories, while square videos and landscape videos fit in-feed placements. It’s also worth checking each platform’s accepted formats (MP4 and MOV are safe bets) and resolution before you export.
- Make sure your text is readable, and that nothing important gets buried under buttons, captions, or profile icons.
- Stick to one main idea per video. If you’re trying to explain three things, you probably have three videos.
- Use a clear call to action when it makes sense, whether that’s “follow for more,” “shop now,” “read the full guide,” or “save this for later.”
Get these basics right first, and length becomes the easy part.
FAQ: Social media video length
What is the ideal social media video length for engagement and performance?
There’s no single ideal length, because it depends on the platform and the format. Most short-form videos land between 15 and 60 seconds, and many platforms perform best in the 15-to-30-second range. Short videos tend to earn higher completion rates, which can help improve performance because platforms often use watch time, retention, and engagement signals to decide what gets recommended.
How does optimal video length vary across TikTok, Instagram, YouTube, LinkedIn, and Facebook?
Optimal video length varies by platform, but most sit in the short-form range. Aim for 20 to 35 seconds on TikTok, 15 to 45 seconds for Instagram Reels, and 15 to 45 seconds for Facebook Reels (or 30 to 60 seconds for Facebook feed video). LinkedIn favors 30 to 60 seconds. YouTube is the outlier, where standard videos run 6 to 12 minutes while Shorts stay at 15 to 45 seconds.
What social media video length drives the highest watch time and retention?
Shorter videos drive the highest watch time and retention, since completion rates climb as length drops. LinkedIn found that videos 30 seconds or shorter see a 200% lift in completion rates, and across platforms, clips in the 15-to-30-second range tend to hold viewers best. This matters because TikTok, Reels, Shorts, and Facebook all use watch time to decide what to recommend, so a short video watched to the end usually outperforms a long one.
How do brands choose the right video length for different marketing goals?
Brands choose the right video length by matching it to the goal. For brand awareness, keep videos short, around 6 to 15 seconds, to reach the most people fast. For consideration, like tutorials, demos, or testimonials, 15 to 60 seconds gives room to explain without losing attention. For conversion, a clear call to action matters more than runtime. The platform sets the ceiling, but the goal should decide where you land within it.
