How long can IG Reels be? In 2026, Instagram Reels can be up to 3 minutes (180 seconds) when recorded in-app. If you upload a pre-recorded video from your camera roll, the limit extends to 15 minutes. Some accounts in Instagram's extended rollout can even record up to 20 minutes.
But longer isn't always better. The Instagram Reel length that performs best is often far shorter than the maximum. According to data from Socialinsider, Reels between 7 and 15 seconds achieve the highest completion rates, while anything over 90 seconds sees a noticeable drop in algorithmic reach.
This guide covers every Instagram Reels length limit currently in effect, the ideal duration for different content types, a full timeline of how these limits evolved, and practical tips for choosing the right length.
Here's what you'll learn:
- Every current Reel length limit (in-app vs. upload vs. ads)
- The best Reel length for engagement (with data)
- How Reels duration limits have changed since 2020
- Ideal length by content type
- Technical specs and file requirements
Instagram Reels Length Limits (2026)
The Instagram Reels length limit depends on how you create the Reel. Here's the full breakdown for 2026:
| Creation Method | Min Length | Max Length | Notes |
|---|---|---|---|
| In-app recording | 3 seconds | 3 minutes | Record one or multiple clips |
| Camera roll upload | 3 seconds | 15 minutes | Pre-recorded video files |
| Extended recording (select accounts) | 3 seconds | 20 minutes | Rolling out gradually in 2025–2026 |
| Reels ads | 3 seconds | 60 seconds | Paid placements in Reels feed |
| Instagram Stories (video) | 1 second | 60 seconds | Per story segment |
The 3-minute in-app limit was introduced in January 2025, doubling the previous 90-second cap. The extended 20-minute recording option is part of a gradual rollout that Instagram began testing with select creator and business accounts in late 2025.
Best Instagram Reel Length for Engagement
The maximum Reels duration keeps growing, but the algorithm doesn't reward length — it rewards retention. Here's what the data shows:
An analysis of 500 viral Reels by CreatorsJet (October 2024 – March 2025) found that Reels between 7 and 15 seconds had the highest average completion rate and shareability, with retention rates between 60% and 80%.
The data breaks down into three tiers:
- 7–15 seconds: Highest completion rate (60–80% retention). Best for viral reach and replay value.
- 15–30 seconds: Strong performance (40–60% retention). The sweet spot for quick tips, product showcases, and educational snippets.
- 60–90 seconds: Lower completion but higher comment engagement. Best for storytelling, tutorials, and before/after reveals.
Anything beyond 90 seconds faces a distribution penalty. Instagram head Adam Mosseri has noted that Reels longer than 90 seconds can hurt distribution in the feed. The option to create longer Reels exists, but it's aimed at specific use cases like mini-documentaries and in-depth tutorials — not everyday content.
The critical metric is the first 3 seconds. Up to 50% of viewers drop off in those initial moments. Reels with a 3-second hold rate above 60% outperform those below 40% by up to 10× in total reach.
Ideal Reel Length by Content Type
The right Instagram Reel time limit to aim for depends on what you're creating. Here are data-backed recommendations:
| Content Type | Ideal Length | Why |
|---|---|---|
| Viral / entertainment | 7–15 seconds | High completion rate drives replays and shares |
| Quick tips / hacks | 15–30 seconds | Enough time for one clear takeaway |
| Product showcases | 15–30 seconds | Show the product in action, end with CTA |
| Tutorials / how-tos | 30–60 seconds | Step-by-step format needs breathing room |
| Storytelling / before-after | 60–90 seconds | Suspense and transformation reward longer watch |
| Behind-the-scenes | 30–60 seconds | Authentic, casual format doesn't need polish |
| Mini-documentaries | 2–3 minutes | Only for exceptional, high-retention content |
For most creators, 15–30 seconds is the safest default. It's long enough to deliver value and short enough to maintain strong retention.
History of Instagram Reels Length Changes
Instagram has steadily increased the IG Reels max length since launch. Here's the full timeline:
| Date | Max In-App Length | What Changed |
|---|---|---|
| August 2020 | 15 seconds | Reels launched as a TikTok competitor |
| Mid-2021 | 30 seconds | Doubled to allow more substance |
| Early 2022 | 60 seconds | Enabled mini-tutorials and educational content |
| Mid-2022 | 90 seconds | Matched competitor platforms |
| January 2025 | 3 minutes | Major expansion for deeper content |
| Late 2025–2026 | Up to 20 minutes | Extended recording for select accounts; uploads up to 15 min |
In under five years, the maximum Reels duration grew from 15 seconds to 20 minutes — an 80× increase. But Instagram's recommendation engine still favors shorter content for discovery, which is why the optimal length hasn't changed as dramatically as the cap.
Technical Specs and File Requirements
Getting the Instagram Reel length right is just one part. Your file also needs to meet these technical specs:
| Spec | Requirement |
|---|---|
| Aspect ratio | 9:16 (full-screen vertical) |
| Resolution | 1080 × 1920 px recommended |
| File format | MP4 or MOV |
| Max file size | 4 GB |
| Frame rate | 30 fps recommended |
| Video codec | H.264 |
| Audio codec | AAC (128 kbps+) |
Uploading in 1:1 (square) or 16:9 (landscape) works but adds black bars on mobile. For full reach, always use the 9:16 vertical format at 1080 × 1920 pixels.
Best Practices for Instagram Reel Length
These practices apply regardless of which Instagram Reel time limit you target:
- Hook in the first 3 seconds. Open with a question, a bold claim, or a visual surprise. Half your viewers decide to stay or leave in this window.
- Match length to content type. Don't stretch a 15-second idea into 60 seconds. Don't compress a tutorial into 10 seconds. Use the table above to pick the right range.
- Add captions. Instagram's own guidelines recommend captions. An estimated 85% of social media videos are watched without sound.
- End with a CTA before the loop. Ask viewers to comment, follow, or save. Place it in the last 2 seconds so it appears right before the Reel loops.
- Test and iterate. Post Reels at different lengths and track completion rate in Instagram Insights. Your audience might prefer 20-second Reels or 60-second ones — data beats assumptions.
- Don't exceed 90 seconds unless the content demands it. Adam Mosseri has publicly stated that Reels over 90 seconds can see reduced distribution. Reserve longer formats for content with proven retention.

Frequently Asked Questions
How long can IG Reels be in 2026?
Instagram Reels can be up to 3 minutes (180 seconds) when recorded in-app. If you upload a pre-recorded video from your camera roll, the limit extends to 15 minutes. Select accounts in Instagram's extended rollout can record up to 20 minutes.
What is the best length for Instagram Reels?
For maximum engagement, aim for 7–15 seconds for viral/entertainment content and 15–30 seconds for educational or brand content. Storytelling Reels perform well at 60–90 seconds. Data from 500 viral Reels shows that shorter Reels consistently achieve higher completion rates.
Do longer Reels get less reach?
Generally, yes. Instagram head Adam Mosseri has stated that Reels over 90 seconds can see reduced distribution in the feed. The algorithm prioritizes retention rate over raw length — a 10-second Reel with 80% retention will outperform a 60-second Reel with 30% retention.
What is the minimum Reel length?
The minimum length for an Instagram Reel is 3 seconds. Anything shorter won't be published as a Reel. For engagement, aim for at least 7 seconds to give the algorithm enough watch-time signal.
Can I upload a 15-minute video as a Reel?
Yes. Videos uploaded from your camera roll can be up to 15 minutes long and will be posted as Reels. However, Instagram's recommendation engine favors content under 3 minutes for discovery. Longer uploads are better suited for an audience that already follows you.
How long should Instagram Reels ads be?
Instagram Reels ads can be up to 60 seconds long. Meta's own advertising guidelines recommend 15 seconds or less for best performance, with the product or brand message appearing in the first 3 seconds.
Conclusion
The Instagram Reels length limit in 2026 gives creators more room than ever — up to 3 minutes in-app and 15 minutes for uploads. But the data consistently shows that shorter Reels (7–30 seconds) achieve the highest engagement and reach. The algorithm rewards retention, not duration.
Choose your Reel length based on content type: quick hits at 7–15 seconds, tips and showcases at 15–30 seconds, and stories or tutorials at 60–90 seconds. Always hook viewers in the first 3 seconds and track your completion rate in Instagram Insights to find what works for your audience.
