You spend an hour editing a video, upload it to Instagram, and find that part of it is cut off or black bars appear around it. This often happens when the video doesn't match Instagram's format. The solution is to resize the video for Instagram before posting.

Resizing a video is easier than you might think. This guide explains the recommended video sizes, aspect ratios, and tools you can use to resize or convert videos on mobile and desktop.

First, let's look at the video sizes that work best on Instagram. Then, we'll cover simple ways to resize your videos using a phone or computer.

What Is the Best Instagram Video Size?

The best Instagram video size depends on where you post. A Reel needs one size. A Feed post needs another. If your video doesn't match, Instagram will crop it or add bars. That’s why it helps to choose a size before you start editing. A few minutes of planning can save you from redoing the whole video.

Instagram Video Aspect Ratio Explained

Instagram video aspect ratio shows how wide your video is compared to how tall it is. It is written as two numbers, like 9:16. The first number is the width. The second number is the height. A 9:16 video is tall, like a phone screen. A 16:9 video is wide, like a TV. Because each Instagram placement prefers a different shape, the best ratio depends on your video.

How to Choose the Right Video Size

Start with where you want to post. Then pick the ratio that fits that spot. Use this table to help you decide.

Placement Best Aspect Ratio Best Size
Instagram Reels 9:16 1080 x 1920 px
Instagram Stories 9:16 1080 x 1920 px
Instagram Feed 4:5 1080 x 1350 px
Widescreen video 16:9 1920 x 1080 px

Instagram Stories and Reels work on vertical-format videos. The image needs to be in 9:16 format. Instagram feed works best with a 4:5 ratio, as it fills the entire screen. Widescreen video ratios are fine, but they'll look very small on mobile, so don't use them unless necessary.

How to Resize Videos for Instagram on Mobile

Your phone lets you make small changes. You can adjust the video and post it within minutes, even when away from your desk. Here’s how it works.

Step 1: Use a Mobile Video Editor

Download a free app like InShot or Splice. Both are easy to use. Open the app and start a new project. Then pick the video from your gallery.

Step 2: Adjust and Export the Video

Next, find the button labeled Canvas or Ratio and choose the Instagram video size you need. For a Reel, that’s 9:16. Your video will now sit inside a tall frame. Zoom in and fill the frame. You can also drag the video to move it. If you want, add a blur or color to the space.

Step 3: Check the Final Instagram Format

When you like how it looks, tap Save. Choose the highest quality your phone allows. Check that nothing is cut off. If all looks good, upload it on Instagram. This is the final step to convert a video for Instagram on your phone.

Tips for Converting Videos for Instagram

Even the best tools can’t catch every mistake. These three tips cover the most common issues.

Keep Important Content in Frame

Always keep faces, text, and key objects near the center. Instagram covers parts of the screen with buttons and captions. People can't see key content at the edges.

Avoid Stretching the Footage

Never pull a video to fit a new size. This makes people look wide or thin. Zoom in or add a blurred background instead. Both keep the video looking natural.

Maintain Video Quality

Start with the best video you have. Export at 1080p or higher. Also, don't save the same video repeatedly. Each save can slightly lower the quality.

FAQs

A1: Use 1080 x 1920 pixels (9:16 ratio), since it fills the whole phone screen and keeps your Reel looking clean on all edges.

A2: Change the ratio, then keep the full video inside the frame. Then fill the space with a blur or a color. Your video stays complete, and nothing gets cut off.

A3: Yes, you can. Switch the ratio to 9:16, then zoom in on the main part of the video or place it in the middle with a blurred background.

A4: It can, but only if you export at a low setting. Save at 1080p or higher, and the video will stay sharp.

Conclusion

Now you know how to resize video for Instagram. First, pick the right size for your post. Reels and Stories use 9:16, and Feed posts use 4:5. Then, use a phone app for edits, or use a desktop tool for more control. Keep your key content near the center and export in high quality. With Edimakor , you can adjust your video to fit Instagram’s format in just a few clicks, making it ready to share without the extra editing hassle.
