Instagram video size and aspect ratio

Reels and Stories are vertical 9:16 at 1080 × 1920. Feed posts are 1080 pixels wide, from 1.91:1 landscape to 4:5 or 3:4 portrait. On your profile grid every post now shows as a 3:4 tile, so keep faces and text away from the top and bottom edges.

Frequently asked questions

What size is an Instagram Reel?

1080 × 1920 pixels, vertical 9:16. Edit on a 1080 × 1920 timeline and export at that size so Instagram does not crop or scale it.

Which aspect ratio is best for feed posts?

4:5 (1080 × 1350) takes the most space in the feed and has long been the standard portrait size. 3:4 (1080 × 1440) matches the profile grid tiles exactly. Landscape posts can be as wide as 1.91:1.

Why is my post cropped on my profile?

Since 2025 the profile grid shows every post as a 3:4 tile. A 9:16 Reel loses some of its top and bottom there and a 4:5 post a little of its sides, so keep the important part in the center.

How do I set up a vertical timeline?

Premiere Pro: create a sequence with a custom frame size of 1080 × 1920, or run Sequence › Auto Reframe Sequence on a finished edit. Final Cut Pro: choose Vertical as the video format when you create the project. DaVinci Resolve: when you create the timeline, untick Use Project Settings and set the resolution to 1080 × 1920.
