Instagram Post Size: A Complete Guide For All Types of Posts

Today, no social media marketing strategy is complete without incorporating Instagram in the plan. It is one of the most popular platforms that brands need to grow their presence on. Instagram lets you share your amazing photos and videos with the world in different formats including feed posts, feed videos, reels, stories, and IGTV. With so many options available, it can be a bit difficult to know which Instagram post size to use and when.

Instagram is a platform that is centered around visually appealing content. Thus, knowing the right sizes is crucial if you want to give your posts the best chance of getting engagement and building an aesthetic feed. 

In this blog by RecurPost, a social media scheduler, we’ll allow you to schedule Instagram posts with much more than the standard answer: “a width of at least 1080 pixels with an aspect ratio between 1.91:1 and 4:5” for Instagram post size dimensions.  

Let’s begin.

Instagram post sizes:

Before we talk about the ideal Instagram post size, you need to have a look at how your current photos and videos. Have you posted all high-quality images? Or are they blurry? Do any of them have missing parts? Is there a black or white background added to images to fit them into the feed? If yes, then this blog will help you a lot.

The most important things you need to consider are aspect ratio and size. The aspect ratio is the image’s width to height ratio. It’s represented in the form of a ratio – for example, 1:2. The first digit is the width, while the second is the height. While image size is the number of pixels that make up your image or video’s height and width.

When you upload a picture in an aspect ratio that Instagram doesn’t support, then it’s either cropped or enlarged to fit. Instagram supports images with a width between 320 pixels and 1080 pixels. If your image is smaller than 320 pixels, they enlarge it, and if it’s wider than 1080 pixels, it’s cropped. 

Align with taking care of the best sizes, you also need to work on the best time to post on Instagram to get maximum engagement on your posts.

Now, let’s learn about the recommended Instagram post size dimensions.

Instagram feed size

When Instagram first launched, users were only able to upload square images. But now, you can upload square, horizontal, or vertical images on Instagram. This provides you the flexibility to upload a wide range of photos. 

The ideal Instagram feed post size for each of these types of pictures are as follows:

1. Instagram square photo size

Even with the option of horizontal and vertical images, the square format is the most popular one.

• Instagram Square Photo Size in Inches: 5 x 5 (width x height)
• Instagram Square Photo Size in cm: 12.7 x 12.7 (width x height)
• Instagram Square Photo Size in Pixels: 1080 x 1080 (width x height)
• Instagram Square Photo Aspect Ratio: 1:1 (width x height)

Thus, for best results, you should consider using this ratio; otherwise, your image might get cropped. No, Instagram does not only post square photos. While Instagram originally started with a square format (1:1 aspect ratio), it now supports multiple aspect ratios for photos and videos.

2. Instagram Horizontal/Landscape post size

When posting horizontal or landscape photos on Instagram, it’s important to use the correct dimensions to ensure your images display perfectly across all devices. Instagram supports a 1.91:1 aspect ratio for horizontal posts, which allows for a wider image that still looks great in the feed. Below are the recommended dimensions and formats to achieve the best quality.

• Instagram Horizontal/Landscape Photo Size in Inches: 10.8 x 5.65 (width x height)
• Instagram Horizontal/Landscape Photo Size in cm: 27.43 x 14.35 (width x height)
• Instagram Horizontal/Landscape Photo Size in Pixels: 1080 x 566 (width x height)
• Instagram Horizontal/Landscape Photo Aspect Ratio: 1.91:1 (width x height)

IG Horizontal Format: JPEG or PNG (recommended formats for best quality)

3. Instagram Portrait/Vertical Post Size

The optimized instagram portrait post size is 1080 px by 1350 px. As a result, the aspect ratio is 4:5, making it the ideal Instagram vertical aspect ratio to avoid cropping. A study has found out that portrait photos receive more engagement as compared to square and horizontal photos. This is because portrait pictures take up more space on the feed. 

Thus, by using portrait orientation, your brand can take up more space on the screens of users’ smartphones. Moreover, their size makes them more eye-catching, and people notice them, ultimately increasing their engagement rate. 

Instagram Video sizes:

Videos receive a lot more interaction on Instagram as compared to still images. And just like photos, you can post them in three different orientations: square, vertical, and horizontal. Here are the best dimensions and aspect ratios of Instagram video post size for designing videos for your marketing strategy:

• Square videos: They should have an aspect ratio of 1:1 and dimensions of 1080 px by 1080 px.
• Horizontal videos should have an aspect ratio of 1.9:1 or 16:9 and dimensions of 1080 px by 607 px.
• Vertical videos should have an aspect ratio of 4:5 and dimensions of 1080 px by 1350 px.

According to a study done by Buffer, square videos tend to receive more engagement than horizontal and vertical videos. Square videos get around 30-35% higher video views while their engagement increases by 80-100%.

• Instagram Video Size in Inches: 5.4 x 9.6 (width x height)
• Instagram Video Size in cm: 13.71 x 24.38 (width x height)
• Instagram Video Size in Pixels: 1080 x 1920 (width x height)
• Instagram Video Aspect Ratio: 9:16 (width x height)

What size is an Instagram story?

For Instagram stories, you need to use vertical/portrait videos. If you create a picture or video in landscape orientation, your videos and photos will show up much like landscape IGTVs — with a lot of dead space around them.

For optimal Instagram Stories, use the following dimensions:

• Instagram Story Size in Inches: 5.4 x 9.6 (width x height)
• Instagram Story Size in cm: 13.71 x 24.38 (width x height)
• Instagram Story Size in Pixels: 1080 x 1920 (width x height)
• Instagram Story Aspect Ratio: 9:16 (width x height)

You should share images and videos with a minimum aspect ratio of 1.91:1 and a maximum of 9:16. In case you wish to cover the entire screen, the best Instagram story size dimensions in pixels would be 1080 px by 1920 px. That’s a 9:16 ratio. 

Instagram stories are mainly designed for people to view them while holding their phones vertically. Thus, using portrait or vertical videos will allow you to take advantage of the full screen without forcing people to rotate their phones or simply skip the stories because of the extra space in landscape photos. 

Instagram Reels sizes:

Just like stories, Instagram reels must be shot vertically in portrait orientation. In IGTVs, you get an option of playing the videos in full-screen mode. However, there is no such option for reels. Reels play directly in the repost on Instagram timeline; thus, you need to record them in portrait mode. 

• Instagram Reels Size in Inches: 5.4 x 9.6 (width x height)
• Instagram Reels Size in cm: 13.71 x 24.38 (width x height)
• Instagram Reels Size in Pixels: 1080 x 1920 (width x height)

Your profile picture is the first thing that people notice when they visit your profile. Thus, it is necessary to ace it. Profile pictures on Instagram are displayed in a 1:1 aspect ratio and the dimensions for this should be 110 px by 110 px. The maximum aspect ratio should be 180 px by 180 px.

Why do you have to worry about Instagram Post size?

1. For better visual storytelling

The size of the images has to be just right to be able to tell your story in the best way possible without losing any message. If you don’t use the right image size, your Instagram post might not appear properly on your profile, which might lead to people not completely getting your message.

2. To avoid cropping out images

This is the most important reason why you need to focus on the Instagram post size. While uploading an image, you might have noticed that it gets severely cropped, and sometimes, this can be highly detrimental to your story and the message you want to give. 

3. To make sure your text appears fine

When you are adding text to your Instagram post, you would want all of it to be properly seen on your profile. And when you are not using the right image size to create your post, you might lose a few words when the image gets cropped. Or else, you might have to pinch the image and make it too small so that it fits without losing any letters or words.

4. To keep logos and other elements intact

Just like text, you might add your brand logo and other elements to your Instagram post. While creating the post, you would need to ensure that the size of the logo does not overtake the image. Thus, having an idea of the correct Instagram post size will help you create a proper image and place your logo and other branded elements properly.
