Instagram Post Size: Complete Guide For Post, Story, IGTV & Reels in 2022

Instagram Post Size Guide

Instagram, which was acquired by Facebook back in 2012, is the second most preferred social media and for a reason. It’s a simple platform that takes cues from Facebook and some which it does better. As of writing this article, the features are on the verge of being a bit overwhelming as the Californian social media giant has added a slew of features recently, and there’s no stopping them now.

Thanks to a lot of engagement, people have made Instagram their 9-5 job where some even earn millions by promoting a brand.

If this is the case with us normal beings then surely celebrities are having a bang-on time. Jennifer’s Aniston’s case can prove my point. The app has now become more user-friendly, especially when it comes to features and versatility.

Instagram is a great medium and all that jazz. Let’s get real! It’s truly frustrating that the app still hasn’t listened to the plight of the millions regarding their default aspect ratio. It has almost become mandatory for users to download any third-party apps that do the trick. But I don’t know why one must retort to it.

So, I decided to do a bit of research to know why Instagram’s default methods are such a pain in the neck (you know what I meant!) This article will be your one-stop webpage to know all that you need to know about the big numbers concerning dimensions, sizes, aspect ratio, and the must-know. This will help your posts get amazing engagement so make sure you bookmark this page.

What is the best Instagram Post Size?

This will be a detailed guide. If you want to be an influencer or want to up the game, you can refer to this page anytime. But before we dive into this convoluted pit, let me explain the basics so that you never have a problem at the root level.

Pixels, Aspect Ratio, Dimensions, Resolution

Technology is constantly evolving so keeping up with terms that tred on a similar path can be confusing. Let’s tear down the basics. You have heard words like pixels, aspect ratio, dimensions, resolution, etc. But can you tell the exact definition of each of these words? If not, I’ll explain it to you in simple words.


Whatever we see on our television, computer, and smartphone screens – they display pixels. These are needed to build the image that we see on the screens. For instance, take a piece of squared-graph paper and color random squares in different colors. Each of these squares can be referred to as pixels. Keep in mind that pixels are not constantly the same size from device to device. In short, a pixel is a dot that can be manipulated.

How are pixels measured?

Pixels are measured by Pixel count and Pixel density. Pixel count is the number of pixels that form your photo.

For instance, if you have a photo that has 2,500 pixels on the horizontal side, and 1,500 on the vertical size it gives you a total of 37,50,000. Because this number is very unsuitable to use, you can just divide it by a million to convert it into megapixels. So 37,50,000 / 1,000000 = 3.75 Megapixels.

Pixel density is how you distribute the total amount of pixels that you have. It is expressed in DPI, i.e. dot per inches, or PPI, i.e. pixels per inches. PPI represents the resolution in pixels of a digital image whereas DPI specifies the number of ink-dots on a printed image.

In simple terms, if you see 75 dpi, it means that the image will have 75 pixels per inch and if you read 400 dpi, it means 400 pixels per inch, and so on and so forth.

The ultimate size of your image depends on the resolution that you choose. If a picture is 4500 x 3000 pixels it indicates that it will print at 15 x 10 inches if you set the resolution to 300 dpi, but it will be 62.5 x 41.6 inches at 72 dpi. Remember that the size of your print changes, the image isn’t resized; you are just reorganizing the current pixels.


The aspect ratio calculates the width to the height which then reduces it like you would a fraction. A screen with 4 x 8 or 20 x 40 dimensions would have resolutions of 1:2. So, if an image is 2:3, it won’t perfectly fit on a 1:2 screen.

What will happen is the edges would each extend beyond what is visible on the screen, have parts of the screen that aren’t covered by the image, or worst, a stretched image.

The aspect ratio is significant when images/videos are resized so that this avoids their distortion. A conventional television and computer display has an aspect ratio of 1.33:1, so if you watch the content meant for it on newer display technologies with a 16:9 aspect ratio, it compromises the size or completeness of the A/V.

Dimension is a measurement of length in one direction. So, a line can be measured in one dimension (1D), a square has two dimensions (2D), and a cube has three dimensions (3D). So a dimension comprises width, depth, and height.


Resolution is the number of pixels presented or displayed on the screen. It is often measured as width x height or pixels per inch. As pixels aren’t continually the same size, it is feasible to have two different devices with the same screen size and different resolutions.

This means the higher the resolution, the higher the image quality, and thus more detail included in the image. Resolution is crucial when you want to print high-quality images and/or graphics. Generally, more resolution indicates more data and information.

Now that we are on the same page when basics are concerned, let’s move on to the real deal.

The best size for Instagram Profile Picture

A profile image is a doorway into your profile. So instead of cropping it and adjusting it clumsily, why don’t you follow Instagram’s aspect ratio for a great-looking profile picture? The aspect ratio of your display picture should be 1:1 and the size of 110 by 110 pixels. Keep in mind that the web version is a bit notorious as it uses a higher resolution, So, always use a larger photo in terms of size so that the picture looks good if viewed on multiple devices.

Moreover, the profile image is round so the corner of your photo will be cropped out. Make sure you choose a profile picture keeping in mind all of these aspects.

Even with the plethora of features that Instagram has introduced over the years, most users prefer to post a photo or a video. So, if you are amongst them, I have listed below everything you need to know about the size, dimensions, etc.
