Instagram Reels Sizes: Dimensions, Specs and Ratios

Reels are the format Instagram pushes hardest, and the one where a wrong size is most visible: the player is full screen, so letterboxing, stretched footage, or a caption hidden behind the like button is obvious to everyone who scrolls past.

Here are the exact Reels dimensions, length limits, and cover specs for 2026. New to the format? Start with our guide to Instagram Reels first.

Instagram Reels size in pixels

The correct Instagram Reels size is 1080 x 1920 pixels with a 9:16 aspect ratio, filmed or exported vertically.

Instagram caps playback at 1080 pixels wide, so a 4K export doesn't play in 4K; it just takes longer to upload and gets recompressed harder. Export at 1080 x 1920 with 30 FPS or higher and let the platform do as little to your file as possible.

If you upload landscape or square footage, the Reels player letterboxes it in the middle of the screen. It works, but the video occupies a fraction of the display, and Reels shot natively vertical consistently hold attention better.

Instagram Reels length

Standard Reels can now run up to 3 minutes, extended from the old 90-second cap. The camera inside the app still offers short segment timers, but uploads from your camera roll can use the full 3 minutes.

The practical limits:

• Minimum length: 3 seconds
• Maximum length: 3 minutes for standard Reels
• Frame rate: 30 FPS or higher
• Maximum file size: 4 GB

Longer isn't a goal by itself. Watch-through rate is what Reels distribution rewards, and a tight 20-second Reel that people finish will usually outperform a 3-minute one they abandon.

Instagram Reels safe zones

Instagram draws its interface over your video: username and caption stacked along the bottom, the like, comment, and share buttons down the right edge. Roughly the bottom quarter and the right tenth of the frame can be covered at any moment.

Keep subtitles and on-screen text centered and clear of those regions. The free safe zone checker overlays the exact interface zones on any frame so you can verify a design before posting.

Instagram Reels cover size

Reel covers are 1080 x 1920 pixels, the same 9:16 canvas as the video. But the cover is displayed in two other crops:

• On your profile grid it shows as a 3:4 rectangle
• In some feed placements it crops toward square

So design covers with the subject and any title text in the center of the frame, and check the grid preview before you publish. If your grid layout matters, the free Instagram feed planner shows how the cover will sit alongside your existing posts.

Instagram Reels caption length

Reel captions allow up to 2,200 characters, the same as feed posts, though only the first line shows in the player until someone taps. Put the hook up front. If you're stuck on wording, the free Instagram caption generator drafts options you can edit down.

Reels sizes compared to other Instagram formats

Reels share the 9:16 canvas with Stories, but feed posts, carousels, and profile pictures each use different dimensions. The full table is in our guide to Instagram post sizes.

Once your Reel is exported at the right size, you can schedule Instagram Reels with Pallyy: upload the video, drop it on the calendar, pick a cover, and it publishes automatically at your chosen time.
