Resize a video for Instagram
An Instagram video should be 1080 × 1920 (9:16) for Reels and Stories, and 1080 × 1350 (4:5) for a post in the feed. Choose your video, pick the shape, and get an MP4 that size: cropped where you drag it, or whole on a blurred background. Free, made in your browser, nothing uploaded.

How to resize a video for Instagram
- Choose the video, or drop it on the page.
- Pick the shape: 4:5 for the feed (already picked), 9:16 for a reel or a story, 1:1 for a square post.
- Crop to fill or Blurred background: drag a crop onto what matters, or keep the whole picture.
- Press Resize video, then download the MP4 and post it. Up to 30 minutes at a time.
Instagram video sizes
| Where | Make it | Instagram takes |
|---|---|---|
| Reels | 1080 × 1920, 9:16 | From 1.91:1 to 9:16; at least 720 px and 30 fps; up to 20 minutes |
| Stories | 1080 × 1920, 9:16 | Meta recommends 9:16, so nothing is cropped or left blank |
| Feed post | 1080 × 1350, 4:5 | From 1.91:1 to 4:5 |
| Square post | 1080 × 1080, 1:1 | Inside the feed's range |

Feed post, reel or story?
A reel is how a video reaches people who don't follow you yet: make it 1080 × 1920 and keep it under 3 minutes. A story is the same shape and is for the people who already do. A feed post at 4:5 takes the most room a post can in the feed.
The same 9:16 video works for a reel, a story, a TikTok and a Short. Read how to make Instagram Reels for the rest, or make one for TikTok with the TikTok resizer.
Mind the edges
On a reel, the caption, your name and the buttons sit over the bottom and right of the video. Keep faces and text toward the center; the safe zone checker shows where Instagram's buttons fall.
Questions
What size should an Instagram video be?
1080 × 1920 (9:16) for Reels and Stories, which fill the screen. For a post in the feed, 1080 × 1350 (4:5), the tallest shape a feed post takes, so it covers the most of the screen as people scroll.
How do I resize a video for Instagram?
Choose it here; 4:5 for the feed is already picked. For a reel or a story, pick 9:16 instead. Crop to fill and drag the picture into place, or pick Blurred background to keep all of it, then press Resize video and download the MP4.
Why does Instagram crop my video?
A feed post can be from 1.91:1 wide to 4:5 tall, and a reel from 1.91:1 to 9:16. Anything outside that is cropped by the app, where it chooses. Resizing first to 1080 × 1350 or 1080 × 1920 means you choose what stays.
How long can a reel be?
Up to 20 minutes, but Instagram only recommends reels of up to 3 minutes to people who don't follow you. Instagram asks for at least 720 pixels and 30 frames a second.
Can I post a horizontal video without cropping it?
Yes. Pick Blurred background: the whole picture sits in the middle of a 4:5 or 9:16 frame on a blurred copy of itself, so nothing is cut and the frame is still filled.
Is my video uploaded?
No. It's resized in your browser and saved on your device as an MP4 with its sound. Free, with no watermark.
