Instagram Reels Size and Dimensions

The core numbers

• Aspect ratio: 9:16 (full vertical).
• Recommended resolution: 1080 × 1920 pixels.
• Minimum practical width: 1080 pixels — smaller uploads get scaled up and look soft.
• Orientation: portrait. Landscape video is technically accepted but displays with large empty bars and looks out of place in the Reels feed.

If you shoot vertically on a phone, you already meet these specs — default phone video is 9:16 or trims to it cleanly. Problems usually come from editing exports and re-used footage, not from the camera.

How Reels are cropped in the feed

Your Reel only displays at full 9:16 in the full-screen Reels player. When it appears as a preview in the home feed or as a thumbnail elsewhere, Instagram shows a cropped, more square version — roughly a 4:5 or 3:4 window cut from the center of your video.

That means the top and bottom of your frame can be cut off in previews. If your opening text sits near the top edge, feed viewers may see a Reel with its headline missing — and swipe past a video that made no sense to them.

Safe margins for text and key content

Two things eat into your frame: the preview crop just described, and the Reels interface itself — username and caption along the bottom, like/comment/share buttons along the right edge.

• Keep text and important action in the middle band of the frame, away from the top and bottom edges.
• Leave the bottom quarter of the frame clear of anything that must be read — the caption overlay sits there.
• Keep the right edge clear of small details — the button column covers it.
• Faces and products are fine anywhere visually, but anything the viewer must read belongs in the center.

Cover image size and the grid crop

The cover you choose is stored at the same 9:16 shape as the Reel — 1080 × 1920 works. But if you share the Reel to your main grid, the grid thumbnail shows a center crop of that cover, so tall covers lose their top and bottom.

The practical rule: design covers so the subject and any text sit in the middle of the frame. That way the cover reads correctly both in the Reels tab (full height) and on the grid (center crop). Instagram also lets you adjust which part of the cover shows on the grid — worth ten seconds on every Reel you share to your profile. There's more on making covers work as a set in how to create better Reels.

Length options

Instagram has extended Reel length several times — from the original short clips up to multi-minute Reels today, with recording caps in-app and longer limits for uploaded video. Because these limits change, check the current cap in the app rather than trusting any article's number, including ours.

More useful than the maximum: the right length is however long your idea stays interesting, and shorter usually wins. A Reel people finish serves you better than a longer one they abandon — the reasons are covered in how Instagram Reels work.

File format and frame rate

• Container: MP4 is the safe choice (MOV from iPhones also works).
• Video codec: H.264 — the standard virtually every phone and editor exports by default.
• Frame rate: 30 fps is the standard and works everywhere; 24 and 60 fps are also accepted. Whatever you choose, keep it consistent across clips in one Reel to avoid stutter.
• Audio: AAC, which again is the default everywhere.

If you never touch export settings, your phone already produces all of this. These specs mainly matter when exporting from an editor: pick MP4, H.264, 1080 × 1920, and the frame rate you shot at, and you're done.

Why Reels come out blurry — and the fixes

Instagram re-compresses every upload, so some quality loss is normal. Noticeably blurry Reels, though, usually trace back to one of a few causes:

1. Upload quality setting turned down. In Instagram's settings, look for the data usage / media quality options and enable uploading at highest quality.
2. Uploading on a weak connection. On poor mobile data, the app may upload a reduced version. Upload over Wi-Fi when you can.
3. Multiple rounds of compression. Video that's been sent through a messaging app, downloaded from another platform, or exported several times gets softer each round. Always upload from the original export.
4. Screen recordings of video. Recording your screen playing a video re-compresses it badly. Use the original file instead.
5. Low-resolution source. Footage below 1080 pixels wide is upscaled and can't be sharpened after the fact.

Sharpness isn't only cosmetic — clean, well-lit, correctly sized video is part of what makes a Reel suitable for recommendation, alongside the habits in our Reels tips.

Quick reference

• Ratio 9:16, resolution 1080 × 1920, portrait only.
• Keep text in the middle band; bottom quarter and right edge get covered by the interface.
• Feed previews crop to roughly 4:5–3:4 — center your key content.
• Covers: subject and text centered, so the grid's center crop keeps them.
• Export MP4, H.264, 30 fps (or your shooting frame rate), AAC audio.
• Upload the original file, over Wi-Fi, with highest-quality uploads enabled.
