Ideal Dimensions And Lengths For Your Reels


Instagram Reels are one of the most powerful tools for growing your brand, building visibility, and selling digital products. But to truly stand out, you need to make sure your content looks professional—and that starts with getting the dimensions and length just right.

Here’s your quick and easy guide to optimizing your Reels for the best performance.

Best Dimensions for Instagram Reels

To make your content look crisp and polished on every screen, stick to these specs:

Recommended Size: 1080 x 1920 pixels
Aspect Ratio: 9:16 (vertical)
File Format: MP4 or MOV
Max File Size: 4 GB
Safe Zones: Keep important text or visuals centered—Instagram crops edges in previews

Using these dimensions ensures your Reel displays correctly on all devices and avoids being cut off in the feed or Explore page.

Best Length for Instagram Reels

Instagram allows Reels to be up to 90 seconds long—but that doesn’t mean you always should use the full time. Here’s what works best:

7–15 seconds: Ideal for trends, quick tips, and high engagement
15–30 seconds: Great for tutorials, product showcases, or storytelling
30–60 seconds: Perfect for deeper educational content or faceless walkthroughs
60–90 seconds: Use sparingly for detailed content that hooks from the start

Pro Tip: The shorter and more impactful your Reel, the higher the chances it gets watched till the end—which boosts visibility in the algorithm.

Why Length and Size Matter

Instagram prioritizes content that:

• Fits full-screen vertical mode
• Loads fast and plays smoothly
• Gets watched from start to finish

Optimizing your dimensions and video length increases your chance of landing on the Explore page, boosting views and engagement.
