Instagram Sizes & Dimensions Guide

With all the new formats and updates to Instagram, it can be tricky to know how to format and size your photos and videos for feed, story, IGTV and live.

That’s why we’ve put this guide together, alongside a free infographic, to help you optimise your content and make the most out of Instagram.

What’s the difference between aspect ratio and image size?

When posting Instagram photos and videos you need to consider aspect ratio and size:

  • Aspect ratio – how the width of the image compares to the height (just like L x W x H – just without the L). It’s shown as a ratio e.g. 4:5. 4 is the width of the image and 5 is the height.
  • Size – the number of pixels your image should contain. Again, this is shown with two numbers, first representing the Width and second the Height.

What do aspect ratio and size mean for your posts?

Instagram allows photos and videos with widths between 320px and 1080px:

  • If your photo or video is smaller than 320px, Instagram will enlarge it to 320px.
  • If it’s wider than 1080px, it will size it down to 1080px.

Now, when you share to Instagram, it stores multiple sizes of the photo or video and the image that gets displayed on Instagram (app and web) is usually much smaller than what you uploaded.

EXAMPLE: You upload a photo with a width of 1080px, the image that’s shown on Instagram will be compressed to a smaller size. Take the photo below from @thelandscaperscircle as an example.

A post shared by The Landscaper’s Circle (@thelandscaperscircle) on

We uploaded a post that was the size 1080px width by 1080px height, but on Instagram, it’s compressed to X.

So, with all this information – Should you bother editing to bigger image sizes?

DEFINITELY! It’s always better to post at a higher resolution so that when Instagram compresses your post it still looks a good image quality.

However, DO NOT put in a photo that’s really large like 5000px by 5000px, this will harm your photo rather than help! If you stick to our post guide, you will get high-quality images for your Instagram by following the correct sizes and aspect ratio. As you also need to get the aspect ratio right, otherwise Instagram will crop your image.
