1080×1920 (9:16) for Reels and Stories, 1080×1350 (4:5) for a portrait feed post, and 1080×1080 for a square. The profile grid shows 3:4 tiles, 1080×1440.

To resize a video for Instagram without cropping, choose the shape it is going to above the drop zone (9:16 for Reels and Stories, 4:5 for the feed, 3:4 for the profile grid, 1:1 for a square), then add the clip. The whole frame is scaled to fit and the leftover space is filled, by default with a soft blur of the clip itself. Press Export video and post the MP4.
Instagram doesn’t shrink a video to fit; it zooms and trims it to fill its own shape. A landscape clip uploaded as a Reel loses its sides, and a tall clip in the feed loses its top and bottom. Resizing it to Instagram’s shape first, with padding rather than a crop, leaves the app nothing to cut. If you want a visible frame instead of a fill, the Instagram video border page starts on a clean white edge.
| Where it shows | Aspect ratio | Size from a 1080p clip | Shape to pick |
|---|---|---|---|
| Reels | 9:16 | 1080×1920 | 9:16 |
| Stories | 9:16 | 1080×1920 | 9:16 |
| Feed post (portrait) | 4:5 | 1080×1350 | 4:5 |
| Profile grid tile | 3:4 | 1080×1440 | 3:4 |
| Square post or carousel | 1:1 | 1080×1080 | 1:1 |
Sizes assume a 1080p source: the canvas’s shorter side always matches your clip’s shorter side, so a 4K clip comes out at twice these numbers. Instagram shows 1080 pixels across, so pick 1080p under Export settings → Size for a 4K source and save the upload time. Every shape and size is compared in the video aspect ratio guide.
How to resize a video for Instagram
Pick the Instagram shape
Above the drop zone, choose 9:16 for Reels and Stories, 4:5 for a feed post, 3:4 for the grid or 1:1 for a square. You can still change it later under Shape.
Add the video
Drop the clip on the tool, or press Select video (Choose video on a phone). It appears straight away, fitted inside the new shape over a blurred copy of itself.
Choose what fills the space
Keep Blurred background, or pick Clean white, Black or Gradient under Look. Drag Border width down to 0% to make the picture as large as the shape allows.
Export and post
Press Export video, then Download video. On a phone, tap Share and choose Instagram, or save to Photos and post from the app.
Why Instagram crops your video
Every part of Instagram has a fixed frame. Reels and Stories fill a phone screen at 9:16, the feed allows up to 4:5, and since early 2025 the profile grid shows each post as a 3:4 tile. When a clip doesn’t match, Instagram zooms in until the frame is full and trims whatever spills over. That is why a group shot loses the people at the edges, and why on-screen text gets cut off.
Padding works the other way round: the video shrinks until all of it fits, and the space it leaves becomes part of the picture. Instagram then sees a video that already has its shape, so it shows the whole thing.
Blur, border or a plain colour?
- Blurred background fills the gap with a soft, moving copy of the clip. It looks full screen, which suits Reels. Raise Darken background if it competes with the sharp picture.
- Clean white or Black make a deliberate frame. White suits a consistent grid; black disappears in dark mode.
- Gradient gives you two colours of your own, handy for brand colours or a title above the clip.
- A background picture can sit behind the video too: see adding a background to a video.
Keep the important part in the middle
Instagram lays its own buttons, captions and account name over the bottom and right of a Reel, and the grid and feed can show a cut-down preview of a tall video. Keep faces and text towards the centre. Drag the picture in the preview, or use Top to bottom under More options, to lift it clear of the caption area.
If one video has to work as a Reel and as a feed post, export it twice: once at 9:16 and once at 4:5. Each takes a minute and neither is cropped.
Resizing on iPhone and Android
The tool works in Safari on iPhone and iPad and in Chrome on Android, with nothing to install. Choose the shape, tap Choose video, pick the clip from Photos or Files, and export. The clip is resized on the phone itself; it isn’t uploaded anywhere. When it finishes, Share hands the file to Instagram or saves it to your camera roll.
Long or 4K clips take a while on older phones. Picking 1080p under Export settings makes the job lighter and is all Instagram displays anyway.
Resizing for Instagram: questions
How do I post a full video on Instagram without cropping?
Resize it to Instagram’s shape with padding before you post. Pick 9:16 or 4:5 here, add the clip, and the whole picture fits inside, with a blur or colour around it.
What is the best aspect ratio for Reels?
9:16, which fills the phone screen. Keep the subject and any text in the middle so the feed and grid previews show them too.
Can I resize a landscape video for Instagram Stories?
Yes. Pick 9:16: the landscape picture spans the width of the screen, with a blurred or coloured fill above and below it.
Does resizing a video for Instagram lower the quality?
It is re-encoded once, and Instagram compresses it again on upload. Set Quality to High under Export settings to give Instagram the cleanest possible copy.
Is my video uploaded to resize it?
No. The resizing happens in your browser and the new file is saved straight to your device.
