Instagram has swept the world off its feet ever since its launch. It has more than a billion users monthly as a part of its community. Marketers are hopping onto the platform to leverage the addictive scrolling behavior of users.  

All thanks to its myriad ways of posting varied content types. Be it posts, Instagram reels, landscape videos, or stories, Instagram floods with eye-pleasing content. However, figuring out the perfect image size can be a menace.  

But why does it matter to nail the image size on Instagram?

Although Instagram compresses your photos and videos, it is preferable to share them at an optimal resolution. That way, even after compressing, the quality of your uploads remains undistorted. 

Before we walk you through this one-stop guide to all Instagram image sizes, here are 2 terms you know.

  • Aspect ratio: It is the width of an image to its height. For example, in the 4:5 ratio, 4 means width and 5 means height.
  • Size: Itis the number of pixels that constitute the width and height of any photo or video. For example, 1080px by 1920px means that the width of the photo is 1080px and the height is 1920px.

Note: Instagram uploads photos at the best resolution possible up to a width of 1080px. The width of any photo must be between 320px and 1080px. On the other hand, if the aspect ratio is unsupported, it will be cropped, which may cause quality loss.

Now that you know the basic dimension, let’s get started with the guide!
