9:16 Vertical Video

BEST CHOICE FOR REELS

9:16

Best Resolution: 1080 × 1920

For Instagram Reels, 9:16 vertical video is the best choice. It fills the entire mobile screen and is the format Instagram is designed around for short-form video. If you're filming content specifically for Instagram Reels or Stories, shoot vertically whenever possible.

16:9 Widescreen Video

NOT RECOMMENDED FOR MOST INSTAGRAM POSTS

16:9

Best Resolution: 1920 × 1080

16:9 video works on Instagram, but it uses much less screen space on a phone. Unless your video was specifically created for landscape viewing, use 9:16 for Reels and Stories or 4:5 for feed posts instead.

1:1 Square Video

STILL WORKS, BUT NOT IDEAL

1:1

Best Resolution: 1080 × 1080

Square video still works on Instagram, but it takes up less vertical screen space than 4:5 or 9:16 video. It can be useful for older content or graphics designed in a square format, but we would not make it your default choice for new Instagram videos.

4:5 Vertical Video

BEST CHOICE FOR FEED POSTS

4:5

Best Resolution: 1080 × 1350

For Instagram feed posts, 4:5 vertical video is one of the best options because it takes up more screen space than square or landscape video without using the full-screen Reel format. If the video is meant primarily for the feed, 1080 × 1350 is the size we recommend.
