Instagram Post Size

With so many different post options, it’s hard to know which Instagram post size to use and when. Instagram is a platform that offers a wide range of content alternatives, including live videos, IGTV videos, stories, and posts. For each type of material, you must follow specific image requirements.

This page contains everything you need to know about Instagram post size guidelines. We’ll discuss the aspect ratios and resolutions required for various kinds of Instagram content and provide easy ways to resize photos.

A complete guide for Instagram post size

Images on Instagram can be between 320 and 1080 pixels in size; however, adding images to posts, stories, and IGTV requires following certain rules. Instagram enlarges images that are smaller than 320 pixels. Additionally, if they exceed the top limit, they will be scaled to 1080 pixels or less. Therefore, you shouldn’t worry too much about image size because Instagram handles it for you automatically.

You should be aware of the minimum and maximum image sizes for various kinds of Instagram posts, though. These are the detailed instructions.

Each photograph on social media must have the correct file size and resolution for posting. Social media image specifications are essential to marketers because they affect post engagement, account legitimacy and attractiveness, and content quality. Unfortunately, resizing photographs on Instagram without adhering to the correct file specs can lessen the visual impact of your post.

Previously, Instagram post sizes comprised square photos with a 1:1 aspect ratio. Users had to crop larger images to fit their photographs into the designated size, making the compression process less effective and producing pixelated photos.

1. 1:1 Square Images

These are the typical square photos that you see on Instagram. Instagram offers a very simple auto-cropping feature if you would like to employ this option. It used to be hard to upload square photos because most cameras could only take portrait or landscape orientations. You can snap a square photo straight from your iPhone or Android phone with the gadgets and camera apps available today.

2. 1.91:1 Landscape

You may have seen some of these horizontal photographs on Instagram posts. It can be challenging to include these kinds of photos because most landscape photos have a 16:9 aspect ratio rather than a 1.91:1. Once posted, your picture will have a black border around it when it is in the gallery.

A black border around a post is generally not visually appealing. This may cause the post to look out of place because it is inconsistent with other posts on the user’s or brand’s Instagram account.

3. 4:5 Portrait

Images in posts with a 4:5 aspect ratio are in portrait format. Since you may take them using your mobile device’s camera, uploading them is simple. Furthermore, you might still crop your portrait photo for Instagram even if it doesn’t have the same aspect ratio as the post.


Instagram allows you to generate many kinds of material, including posts, stories, and IGTV videos, which is one of its most outstanding features. Additionally, there are various image size requirements for each of them, as well as the ability to upload photographs. After talking about the different image sizes permitted for Instagram posts, let’s look at the rules for Instagram Stories.


The recommended size for an Instagram post size is 1080 pixels by 1920 pixels with a 9:16 aspect ratio. This is the ideal image size to guarantee that the picture fits the story precisely and that no black border exists.

On the other hand, you can upload any photograph between 1.91:1 and 9:16 to Instagram Stories. The image can be easily cropped to suit the story, or it will automatically fill in the space with a black border.

Does your choice of image size impact your feed?

Many individuals are concerned that using a combination of square, portrait, and landscape photos may make their Instagram feed appear disorganized and uneven. That isn’t the case, though, as all of your photos show up on your stream automatically as square images.

This implies that landscape or portrait-style photos will be seen when someone opens a post. But because the preview image for every post will be square by default, your feed will seem consistent from top to bottom. Consequently, your Instagram grid will seem flawless regardless of the image you use.


Instagram automatically resizes photos to the proper size for every kind of content. You must be aware of the image sizes to prevent that and ensure your photos fit precisely without cropping.

Black borders are frequently displayed on cropped photographs, detracting from their aesthetic appeal. To avoid this, you should upload your photos in a size that precisely fits the dimensions of your post or story. With the help of this article on Instagram post size, you can produce excellent Instagram image content.
