Best Instagram Dimensions and Size

From posts in the feed to videos and reels on Instagram, knowing the dimensions and size will help you create awesome photos and videos. Such type of content is one of the best ways to engage with your followers so you have to give the best. 

That’s why we have created this list of ideal Instagram image dimensions and sizes for you to create better posts for your followers. This article covers every photo and video size that you need to focus on while creating your content. 

Come let’s check it out!

What is Instagram Aspect Ratio?

Aspect ratio refers to the width in relation to the height of a picture. For example, if the ratio is 5:10, the first represents the width and the second represents the height. 

That is why you have to make sure that your image comes within the guidelines, otherwise, it will be cropped to fit the actual size. That will end up in part of your image being lost. 

Now with the ratios being suggested in editing apps and tools, you can always enhance your content correctly before posting.

What Are Instagram Post Photo Dimensions?

The width and the height of an image are comprised of a number of pixels which is the size of an image. 

Like aspect ratio, size is also expressed by two numbers: one for the width and one for the height. 

For example, a picture that is 1080px X 1080px is larger than the one that is 50px X 50px. 

It is always wise to post an image at optimal resolution because that way your image won’t be much affected even though Instagram compresses your image. 

Dimensions of Various Instagram Posts 

When the app was first launched, users were only able to upload images in a 1:1 ratio. They were forced to crop their amazing portraits to fit into the actual size. But later in 2015, Instagram listened to the user’s feedback and introduced horizontal and vertical photos. Now let’s talk about the size with this in mind.

  • Square photo size

The ideal size of Instagram square photo is 1080px X 1080px. To avoid getting your image cropped, you can either crop the image to this size or capture an image to this size. 

You can capture a 1:1 image directly in an iPhone camera. So for better results, your image must be between 320px by 320px and 1080px by 1080px. 

  • Portrait size

The ideal size of Instagram portrait is 1080px by 1350px. 

You can fit a picture to this size without cropping by using portrait and landscape images. The aspect ratio of Instagram portrait is 4:5 and the photo size is 1080px by 1350px. 

  • Horizontal and vertical photo size

This can be a hard one because the aspect ratio of a landscape photo is 1.91:1. Your image will look amazing with these dimensions. You can also upload photos up to a ratio of 16:9 and Instagram will automatically add a border to the image. The ideal size of horizontal photo is 1080px by 1350px. 

For vertical photos, your image should have an aspect ratio of 4:5. Anything longer than that will be cropped by Instagram. 

  • Instagram stories

You can share anything in the stories as long as it has a minimum aspect ratio of 1.91:1 and a maximum of 9:16 with an ideal size of 1080px by 1920px. 

  • Instagram videos

Your feed videos aspect ratio should be from 16:9 to 4:5. And the videos must have a maximum file size of 4GB. 

  • Instagram reels

It is always advisable to shoot directly on mobile to stick to the optimal size which is 9:16. Video captions will be displayed at the bottom so avoid having anything down there. 

  • IGTV Posts

The ideal cover photo size for IGTV is 420px by 654px. The aspect ratio of vertical IGTV posts is 4:5 to a maximum of 9:16. The aspect ratio of a horizontal post is 5:4 to a maximum of 9:16. 


Instagram is an excellent place to connect and you sure want to display your content amazingly. Don’t be worried about how your post will appear in your user’s feed despite the aspect ratio. Be it landscape, portrait, or square, the photos will be cropped to 1:1 to fit your preview and your followers have to open them to see the actual image size.
