Instagram Photo and video size

Previously, we were limited in size on Instagram for photo posts, and Instagram allowed uploading photos that were square in shape, so the length and width of them were equal.

But recently, this restriction has been removed and it has been possible to upload photos and videos in horizontal and vertical dimensions with various sizes on the Instagram platform.

In the following, you can see the standard dimensions of the Instagram photo and video size dimensions in different sections of post, story, and it.

In general, there are two sizes for Instagram photos and three different sizes for Instagram videos.

It may not be important for many users to know the size of the video, but it is definitely important for those who use this medium to grow their business.

Instagram currently has three sizes for your photos and videos:

  • Squares size
  • Horizontal size
  • Vertical size

Square Photo Size on Instagram

Your Instagram post photos don’t have to be square, and you can share horizontal or vertical photos on your page.

But if you want to publish a photo that is too wide and too high, you need to cut it.

If the image is larger than 1080px * 1080px, Instagram will automatically compress its size to display it. Excessive image compression mainly affects image quality.

The same is true for images that are smaller than 320PX * 320PX. Instagram has to take a picture to fit the image in its standard dimensions, and this reduces the quality of the image.

Therefore, in order to have the best quality on Instagram, set the size to other 1080px * 1080px.

It’s also interesting to note that Instagram Web maintains photo quality much more than a mobile app

NOte iconAs long as your image width is between 320 and 1080 pixels and the aspect ratio is observed correctly, the program will maintain image resolution.

But if the aspect ratio of your image is not supported, it will cut it, and this will definitely affect the image quality.

So if you want to maintain the quality of your image, before uploading it to Instagram, be sure to change the width of your image to a maximum size of 1080 pixels to prevent it from being compressed or cut automatically.

Vertical (Portrait ) Photo Size on Instagram

If you are uploading a larger vertical image or rectangular image, it will ask you to crop part of the image to fit the standard size.

So if you want to upload a photo to Instagram without any cuts, you can use the full-size button in the lower-left corner of the image when uploading the photo:

  • The ideal size for Instagram photos and videos is 1080px * 1350px. The aspect ratio of photos and videos should be 4: 5.
  • The ideal size for Instagram photos and videos is 1080px * 1350px. The aspect ratio of photos and videos should be 4: 5.
  • To get the best resolution in vertical photos, resize the image to 1080px * 1350px. This way, auto-compression doesn’t affect the quality of your vertical photos.

 Horizontal (Landscape ) photo size on Instagram

The aspect ratio of 1.91: 1 should be maintained in rectangular horizontal photos. With these dimensions, the quality of your horizontal photo will be preserved on Instagram.

However, you can also upload horizontal photos with a 16: 9 aspect ratio on Instagram.

In this case, Instagram will automatically add a margin around your photo.

The reason we recommend this aspect ratio for horizontal Instagram movies is that you will need a lot of time to edit the movie in a 1.9: 1 ratio.

How to Upload Horizontal Photos on Instagram?

To upload horizontal (Landscape ) rectangular photos on Instagram, you need to go through the following steps:

  1. Tap the Add post tab and select your photo or video to upload.
  2. Tap the full-size button in the lower-left corner. (This option automatically adjusts the size to fit your photo. The same goes for vertical photos.)
  3. After selecting this option, the photo size will be set to horizontal. Tap Next to continue.


What is the Maximum Video size on Instagram for uploading?

A video to upload to Instagram must be at most:

  • 30 frames per second.
  • The length of the film is 60 seconds.
  • The file size is 4 GB.

If your movie does not meet any of the above conditions, you will not be able to upload it.

Since your video is compressed when uploading, we recommend that you use the maximum allowable resolution of Instagram’s minimum video resolution.

In this case, you can maintain the clarity of your videos.

You can use Instagram’s IGTV feature to upload videos over 60 seconds

What are Instagram Story Sizes & Dimensions?

Instagram Story is another amazing Instagram tool through which you can communicate with your audience and upload your daily stories as photos or videos in the story.

You can upload any photo and video with standard dimensions of 1: 9: 1 to 9:16 on Instagram Story.

Do many users ask what is the size of Instagram story photos? If you want your story to be full screen and cover the entire screen, you’ll need a 1920px * 1080px size and a 9:16 aspect ratio.

Instagram Dimensions for IGTV

Instagram’s IGTV is another feature that allows users to upload longer videos. Until now, Instagram IGTV videos must have been vertical with a 9:16 aspect ratio, and it was not possible to upload other dimensions of the video in this part of Instagram.

Recently, Instagram decided to allow users to upload horizontal videos on Instagram.
