Frequently asked questions

FAQ

What are the best dimensions for Instagram videos?

The ideal dimensions for Instagram videos vary based on the post type. Recommended dimensions include:

  • 1080 x 1920 for Stories, Reels, and IGTV videos
  • 1080 x 1350 for Feed videos
  • 1080 x 1080 for Carousel videos

Will resizing a video affect its quality?

It can, but our software prioritizes video quality during resizing. Plus, you can change frames per second and bitrate settings to improve your downloads.

Another factor that can affect the resolution of your posts is Instagram’s settings — they automatically compress videos during upload. To preserve clarity, you should convert videos to Instagram’s file format (MP4) before uploading.

How long can my Instagram video be?

An Instagram post’s maximum length depends on the video type. Here are the limits for each:

  • Instagram Reels: Up to 90 seconds
  • Stories: Up to 60 seconds
  • Feed and IGTV: Up to 60 minutes
  • Instagram Live: Up to 4 hours

Can I resize videos without editing skills?

Yes — our video converter for Instagram can adjust your aspect ratio automatically. To fit your Instagram aesthetic, you can even use AI to add captions, royalty-free music, and style effects to posts.
