How Long Should Instagram Reels Be? A Complete Guide to Maximizing Engagement in 2025

There is no surprise that Instagram Reels are the backbone of engagement on the platform, making up 30% of all time on Instagram. However, the questions that come to everyone’s mind is- How long should these reels be to boost views and engagement? Do shorter reels perform better, or do longer ones drive more retention?

While Instagram has been continuing to make some changes in Instagram reels, its duration, and everything else, brands need to be more conscious about its potential outcome. Let’s break it all down- about Instagram’s latest updates, algorithm insights, and expert strategies that will enable you to create high-performing reels in 2025.

Instagram Reels Length: What’s the Latest Update?

Everyone already remembers the golden 15 seconds rule of short-form videos. This is how Tiktok videos were first introduced, and soon Instagram reels followed through by capping the duration to 15 seconds. With time, Instagram has gradually increased the maximum length of Reels,

• 2020 – 15 seconds
• 2021 – 30 seconds
• 2022 – 60 seconds
• 2023 – 90 seconds
• 2024-2025 – 3-minute Reels being tested in select regions

Adam Mosseri, Head of Instagram, confirmed this latest change in his statement:

"We've heard a lot of feedback from creators that 90 seconds is just too short. So we’re hoping that upping that limit up to three minutes will help you tell the stories you really want to tell." (source)

However, not all accounts have got the access to creating 3 minute reels, as Instagram continues to test and roll out this feature in different regions and contexts.

Does Longer = Better? What the Data Says

Now the main question comes, does the duration of reel directly impact its potential impact? Well, in reality, longer videos allow for more storytelling and context. However, Instagram’s algorithm does not really care about just the duration. It favors content with higher completion rates and watch time.

Here Are Some Key Insights on Reel Performance:

• Short Reels (7-15 seconds) = Higher completion rates and more shares.
• Mid-length Reels (30-45 seconds) = Great for brand storytelling.
• Longer Reels (60-90 seconds) = Work well for tutorials but have higher drop-off rates.
• Reels longer than 90 seconds = May experience lower reach, as confirmed by Mosseri (source).

It is clear that Instagram’s algorithm prioritizes completion rates, so if viewers don’t finish watching, your Reel reach declines. Therefore, it is instrumental for brands to shift their focus from ‘just integrating a perfect hook’ to actually focus on the ‘overall engagement’ and storytelling of their content.

Reel Length vs. Engagement: What Works Best?

Let’s now dive deep into the role of different reel lengths, and what content types work best for them.

Short Reels (7-30 Seconds)

While this is the most common duration of Instagram, here are some content examples that fit perfectly,

• Great for trends & engagement
• Higher completion rates
• Ideal for fast-paced content

💡 Example: A 15-second product teaser featuring fast cuts and trending audio to grab audience attention.

Mid-Length Reels (30-60 Seconds)

These are recommended for content that demands more context, and information for the audience. Here are some characteristics of reels that are 30 to 60 seconds long,

• More time for storytelling
• Better audience retention
• Perfect for educational content

💡 Example: A skincare brand could post a 45 seconds long video explaining an ideal night care routine. Rather than just showcasing the products, the brand’s main focus is also to introduce the key features and benefits of each product. Thus, more time would allow the brand to integrate this approach seamlessly into their content.

Long Reels (60-180 Seconds)

While these long videos are not common yet on Instagram. You could blame the audience's reduced attention span, and lack of storytelling from creators and brands for this. However, we are yet to see how the algorithm continues to prioritise these types of videos.

Here are some pointers that you should know about,

• Best for deep storytelling
• Ideal for interviews & vlogs
• Riskier- higher drop-off rates

💡 Example: A 3-minute "Day in My Life" travel vlog, showcasing a full experience of someone including their morning routine, their work, their breakfast, lunch, hobby, exercise and everything else with powerful narration.

Instagram Algorithm & Reel Performance

Long story short, Instagram mainly ranks Reels based on:

1. Completion rate – Do viewers finish watching?
2. Watch time – How long do they stay engaged?
3. Shares & saves – Is the content valuable?
4. Comments & likes – Are users interacting?

How to Keep Viewers Engaged (Regardless of Length)

• Ensure that you hook viewers within the first 3 seconds. More drop offs in the beginning of the video is a red flag for your brand.
• Data reveals that a large proportion of Instagram users still watch videos without its audio being turned on. Therefore, you should use text overlays for a seamless silent viewing experience.
• Leverage trending audio to not just increase your chances of being visible, but also build familiarity with the users.

Build engagement by incorporating relatable questions or CTAs (call to action) in your videos.

Instagram Reels vs. TikTok vs. YouTube Shorts

💡 Pro Tip: Cross-posting Reels to TikTok, Instagram Reels & YouTube Shorts expands reach but remove watermarks to avoid algorithm penalties.

Conclusion: What’s the Best Reel Length?

Data continually demonstrates that shorter videos have greater engagement rates due to superior completion rates, even though Instagram now allows extended reel lengths up to three minutes. The secret is to keep viewers interested throughout while aligning the length of your material with your particular objectives.

Remember the golden rule: Make your Reel as long as necessary—but as short as possible to maximize engagement and reach.
