Instagram Reels Size, Length and Safe Zone (2026)

The right size for an Instagram Reel is 1080 × 1920 pixels, a 9:16 aspect ratio. Reels up to 3 minutes long can be shown to people who don't follow you yet. Instagram accepts other shapes, but only 9:16 fills the screen.

Below are the full export settings, the parts of the frame Instagram's interface covers, the cover size for your profile grid, and what to do with a horizontal video.

Instagram Reels specs at a glance

How long can an Instagram Reel be?

Every account can post Reels up to 3 minutes, and Reels within that limit can be recommended in the Reels tab and Explore to people who don't follow you. That is the number that matters for reach.

Instagram has been rolling out longer uploads to some accounts, with reports of Reels up to 20 minutes. Those longer Reels mostly reach your existing followers rather than new viewers. The limit varies by account and app version, so check what your own upload screen allows.

The limit is a ceiling, not a target. A Reel should last as long as one complete idea takes and stop there. For most clips cut from a podcast or interview, that is well under a minute.

Aspect ratios compared: 9:16, 4:5, 1:1 and 16:9

Use 9:16. In a feed where every other Reel fills the screen, anything smaller looks like a mistake and gives viewers less to look at.

Instagram Reels safe zone

Instagram draws its interface on top of your video. Text or faces under those elements are hidden, and captions are the usual casualty because the bottom of the frame is the busiest part.

Instagram does not publish exact pixel values for organic Reels, and the overlay shifts with caption length and device. These margins on a 1080 × 1920 frame keep text clear on current phones:

That leaves a safe area of roughly 870 × 1250 px, a little left of center. A longer caption expands over the video when tapped, so keep the most important on-screen text in the upper half of that area.

If you run the Reel as an ad, use Meta's stricter guidance: keep the top 14%, the bottom 35% and 6% on each side free of text, because the ad adds a call-to-action button at the bottom.

Instagram Reel cover size

The cover is the frame people see before they tap. Make it 1080 × 1920, the same as the Reel. Where it shows depends on the surface:

• Reels tab and full-screen view: the whole 9:16 cover.
• Profile grid: a 3:4 crop from the center, about 1080 × 1440. The top and bottom 240 px are cut off.

Put the title and the face inside the middle 1080 × 1440. A cover designed edge to edge loses its headline on the grid.

How to turn a horizontal video into a Reel

Most long videos are 16:9. To make them vertical you either crop to the subject, stack two crops (speaker on top, guest or screen below), or shrink the whole frame onto a blurred background. Cropping looks the most native; it is also the only one that needs the crop to follow whoever is talking.

The three methods, and what each costs in resolution, are covered in detail in the YouTube Shorts size guide. The same advice applies to Reels, because the frame is identical.

Short.now does the crop for you: it reframes horizontal video to 9:16, follows the active speaker, and keeps captions inside the safe zone.

One file for Reels, Shorts and TikTok

One 1080 × 1920 file works on all three. Of the three, Reels covers the most of the bottom of the frame, so if you post the same clip everywhere, place captions for Reels and they will be clear on the others. Details for the other two platforms are in TikTok video size and length and how long YouTube Shorts can be. For which platform to prioritize, see YouTube Shorts vs TikTok vs Reels.

Common Reels sizing mistakes

• Captions on the bottom edge. They sit under your username and caption text. Move them up to the middle.
• A cover with the headline at the top. The grid's 3:4 crop cuts it off. Keep it in the center.
• Posting a 16:9 clip as is. It plays as a thin strip. Crop or stack it.
• Exporting below 30 fps or at low resolution. Instagram compresses every upload; starting from a soft file makes it worse. Export 1080 × 1920 at the source frame rate.
