If you’ve come across the term aspect ratio or video aspect ratio while in the process of creating content for your business but weren’t sure what it meant, you are not alone. But it’s time to change all that.

In this article, we are looking at the different social media outlets and how aspect ratio can play a role in how your photo and video content comes out on various platforms, different social media size requirements, and how to change aspect ratios. We will look at Instagram, Facebook, and YouTube’s video aspect ratio, and more.

What is Aspect Ratio?

Aspect ratio is defined as the width of a picture or video frame in relation to its height. In essence, it is the proportion of your content asset, or, put more simply, its final shape. I.e., horizontal, vertical, or square.  

For example, a square image has an aspect ratio of 1:1. The image resolution could be 500 × 500, 800 x 800 or 1200 x 1200 but the aspect ratio will still remain 1:1. This means a very small image can share the same aspect ratio as a large one. Such a Facebook profile pic compared to an Instagram feed – One is smaller than the other in resolution but they share the same 1:1 aspect ratio and square shape.

Understanding Aspect Ratios

The word aspect ratio is really a professional way of describing a shape, kind of like a picture frame that comes in different formats. The way the aspect ratio is calculated in our digital world today makes it seem super complicated, but really it’s not. In a nutshell – the aspect ratio is the shape of your image or video as it appears on your screen.

It is very helpful and even crucial to understand aspect ratios when creating online content. Without it, the content you upload can look downright bad. Do your videos ever look distorted or stretched? It might be because you don’t know the difference between the 1:1, 16:9, and 4:3 aspect ratios and where they are used. 

Why is Video Aspect Ratio Important?

As we’ve discussed above, the aspect ratio is important because it influences how your photos and videos will look when you share them on different platforms.  Understanding the different aspect ratios will make sharing on various social media sites easier. It will also ensure your content visibility is optimal. Here are a few key benefits of using the right aspect ratio for your content.

Avoids Image or Video Distortion

It is crucial to understand the aspect ratio when showcasing a specific item or subject. Have you ever searched on a photo site looking for a particular theme or topic and found the perfect image, but when you shared it on a specific platform like Instagram, the picture didn’t fit? The aspect ratio also affects how we showcase our subject material when we want a specific image or shot centered or in the background.

For example, you might have an image or video of a headshot, except when you upload it to Instagram it appears too large, or black bars surround it. This is because the image’s aspect ratio is not formatted to the platform you are sharing it on for optimal viewing. The solution is to reformat the image or video with Instagram’s standard shape of  1:1. 

Has an Impact on the Design

Aspect ratio and design go hand-in-hand. The aspect ratio will especially affect how and where you add texts to your video, or captions to photo. It makes a big difference when it comes to creating content to share on social media. 

An additional thing to keep in mind is if you want to combine an image with video footage for a promotional video, and the image has a different aspect ratio than the video. When you go to publish the video, the image will be distorted or not properly centered. It’s simple to fix by resizing your image. With the right online tool, you can effortlessly adjust the aspect ratio of the image to be in alignment with the video.

Prevents Letterboxes

Letterboxes are the black bars you used to see when using older TV screens showing new movies shot at a different aspect ratio. They can also show up on mobile devices when the video uploaded doesn’t match the aspect ratio of the platform it is shared to. Some will know these as cinematic bars. If your uploaded content appears with letterboxes, that means you need to change the aspect ratio. Some people get the aspect ratio of their footage confused when we start talking about the ratio of a screen. To keep it simple, just remember that aspect ratio is really just the shape. So, for example, most televisions have a screen in the shape of 16:9 today, which practically means “horizontal,” and mobile phones have the screen aspect ratio of  9:16, which means “vertical.” 

Why is this important? Because social media outlets take this into account when creating their platforms. Take Instagram, for example; when they created their platform in 2012, users could only upload photos in a 1:1 or square shape. As a result, users who wanted to post landscape and portrait photos had to crop their pictures into a square or use other apps for workarounds.

Today all the social media platforms have adjusted to meet the various formatting needs but you will often run into complications (like black bars or distorted images) that can be easily fixed if you have a basic understanding of the problem. 

The black bars (known as “letterboxes”) are the platforms’ method of formatting footage to ensure it retains its original shape even if the screen is not that same shape. I.e., think about the black bars on the top and bottom of an older TV screen when you’re watching a film recorded in widescreen format. Using the right photo aspect ratio (or video) will prevent any letterbox situation. 

Aspect Ratio and Video Resolution

Aspect ratio and resolution both refer to the frame size and are often confused with each other. Whether you’re an avid video editor or novice, knowing some basic information about aspect ratio and resolution will prove helpful when uploading to the web.

The resolution of an image is the total number of pixels displayed on your screen. Resolution measures how many pixels an image contains. To get the resolution, you would multiply the width times the height. The bigger the resolution, the more defined the image and the bigger your file in terms of megabytes.

So, for example, you could have two videos, both filmed in full HD, that have the exact resolution (number of pixels), but different aspect ratios (width and height of the video) – one showing horizontal 16×9 and one showing vertical 9×16 but both have 1920 x 1080 resolution.

Practical Social Media Examples

Let’s take it further. Again, perhaps you have one image you want to share on two different platforms like Facebook Stories and Instagram. The best shape for Facebook stores is 9:16 (vertical) because they are primarily viewed on mobile devices, but Instagram typically uses a square aspect ratio. The image resolution could be Full HD (1920 x 1080) but you can change the aspect ratio to fit the platforms or where it’s being posted. The same image you can format to a different aspect ratio for Pinterest which generally requires a 2:3 aspect ratio. 

What exactly does all of this mean? Aspect ratio and resolution go hand-in-hand and play an essential part in video production, especially when uploading videos to different social media platforms.

How Aspect Ratio Can Affect Your Viewing Experience

We have already explained the difference between aspect ratio and resolution. Now we understand we can have two videos with the exact high-quality resolution but different shapes due to screen size on different devices. Thus, the primary issue with aspect ratio is a distorted image or the appearance of black bars on either side when viewing.

Matching Aspect Ratios to Video Resolution

Today, the most common video resolutions are HD, Full HD, 4K & 8K. Distorted videos and black bars in a video happen when the video aspect ratio and the screen don’t match. Also, if the video resolution is lower than the screen resolution, you could also get bars on the bottom. In any case, no matter the video resolution, you will always be restricted to the maximum resolution of the viewing screen.

For instance, a video filmed in 1080p will still only give you 1080p resolution, even if you have an 8K monitor with a high resolution. Conversely, if your monitor is 1080p and you have a video filmed in 4k, the video resolution will still be 1080p.

It’s possible to change the video resolution if you find it necessary. Some excellent video converters can help with video format here. However, it’s as easy as editing the aspect ratio to the desired size for the viewing device most of the time. A good video editor like  Promo.com will do the trick in a few simple steps.

Aspect Ratios in 2021 

Since the dawn of the first widescreen film, Old Ironsides, in 1926, we have come a long way in the viewing quality of our devices and screens. Not too long ago, all we had was a square television with a 4:3 ratio screen shape, whereas today, we have mobile phones, smart pads, and widescreen TVs. In any case, it’s not a big deal as YouTube, Facebook, and Social Media channels are the new TV of this generation.

In fact, studies show around 62% of the population watches videos on their mobile devices. Much of the content is on YouTube – however, social media sites today are also primarily video-based. 

Popular Aspect Ratios

Amongst the popular social media sites, the most common ratio shapes are 16:9. 4:3, and 1:1. Aspect ratios are critical for web content because different images require various shapes for different uses. I.e., desktop vs. mobile or blog vs. Facebook. 

It is important to note that most social media platforms allow many varying aspect ratios but not all will perform well for different distributions. For example, a Facebook banner ad is a different shape than a Facebook Story. Each platform has the best practices for various content sizes and ratios listed in each social media section of this article. 

Using the correct aspect ratios ensures your images are displayed as intended without distortion or resolution loss. Let’s take a quick look at the common uses for all three.

9:16 Aspect Ratio

There is no question that this shape is one of the most popular on social media. Whether it’s Facebook or Instagram Stories or watching videos on TikTok, this vertical shape is primarily used because we see everything on our phones today.

1:1 Aspect Ratio

A 1:1 ratio is a square. It means that an image’s width and height are equal. Some common 1:1 ratios are an 8 x 8-inch photo, a 1080 x 1080 pixel image, or general social media profile picture templates.  This shape ratio is also common for print photographs and mobile screens. 

16:9 Aspect Ratio

A 16:9 ratio is generally used for viewing presentation slides, widescreen TVs, or computer monitors. The 16:9 ratio replaced the previous 4:3 ratio for monitors and TV screens, thereby creating a slimmer, more elongated rectangular shape. Common video resolutions in the 16:9 ratio are 1920 x 1080 pixels and 1280 x 720 pixels. Most social platforms support this shape.

4:3 Aspect Ratio

4:3 resolution is fading quickly but not entirely out of date. You can still get certain GoPro’s or different action cameras that give you the 4:3 modes. The common resolutions are generally from 640p x 480p to 1600p x 1200p and a range in between. The 4:3 aspect ratio is becoming less common as our technology has advanced and is being replaced by 1:1. 

Which Aspect Ratio Should You Use?

Determining what is driving your project and message is vital in deciding which photo aspect ratio you should use. If you are sharing your video or image across social media platforms, you need to decide on your video aspect ratio in advance. The biggest question you should be asking yourself is – what platform am I intending to use this content for, and in what format. 

Using Different Aspect Ratios in the Same Video

Sometimes we want to combine a couple of different clips together with different aspect ratios or resolutions. It’s possible to merge them with a good video editor. Likewise, you can use different aspect ratios in a video as the editor will add the bars required to make it work. Still, when you render out a final video, it will have a set resolution and a fixed aspect ratio.

Aspect Ratio & Smartphones

Today there is no question that vertical video is on the rise. With the increase of video viewing on smartphones and social media channels, aspect ratios have shifted to a vertical direction. Instagram’s standard square 1:1 ratio shape is excellent for close-ups of people’s faces but cannot capture the panoramic views we catch with our advanced cameras today.

Mobile phone usage has driven the 9:16 vertical shape into broader acceptance today. Additionally, many people are creating vertical short films and videos for various purposes. Using video to promote small businesses and education has gained immense popularity with the rise of social media.

How to Change Video Aspect Ratio

There are many platforms available today that allow to toggle between a variety of aspect ratios with video resizing tools. Therefore, figuring out what shape ratio to use is not as difficult as it might sound. However, it is critical to understand what aspect ratio is and how to change it to achieve optimal engagement.

One of the best methods of changing the aspect ratio for any platform or website is utilizing online image and video editors. In addition, it is convenient to have all of your brand’s content assets in one place that can be accessed straight from your browser.

Whether you need to change the video shape ratio or an image shape ratio, Promo.com can help and additionally store all of your videos and images in one place.

YouTube permits uploading videos of various sizes that range from 240p to 4K. However, getting the correct resolution isn’t enough. It is essential to consider your video size, length, and aspect ratio when uploading videos on YouTube.

Likewise, the maximum video size is 256GB, or 12 hours, whichever is less with a verified account. However, that doesn’t mean that you can’t upload other ratios. 16:9 is just the standard YouTube size. If you choose to use a different shape ratio like 4:3, then YouTube will automatically adjust the footage by adding the black bars (letterboxes).  

Changing YouTube Video Aspect Ratios 

YouTube gives you the option of choosing the size in which you want to view your video when you upload it by making it available in various sizes. 

However, YouTube also maintains that the speed of your broadband connection and your device greatly determine the screen resolution.
