This article will explain what a video aspect ratio is, it includes common video aspect ratios you see nowadays, and includes recommended aspect ratios for video on various social media platforms.

With that said, let’s dive right into it!

1. What is a video aspect ratio?

Aspect ratio is a digital image projection attribute describing the distance between the width and the height of an image. The dimensions are also defined as shapes such as a square which is 4:3. A rectangle represents the 16:9 standard high definition aspect ratio, and inverted what you see on phones, that will be 9:16. 9 refers to the width and 16 to the height.

2. Commonly used aspect ratios

There is no same aspect ratio that is used across all social media platforms. Depending on which social media platform you are planning to upload, you have to make sure you have the correct aspect ratio for your target audience. The optimal viewing experience is what matters.

16:9 Widescreen

This aspect ratio is recognized as the worldwide reference format for film, mobile devides, DSLR cameras, streaming platforms, social media platforms, and many more. It is known as landscape viewing which include 720p, 1080p HD and 4K resolution.

4:3 Standard

This resolution is originally used in older television screens, which transformed into mobile use as this aspect ratio works really well for Instagram and Facebook videos, referring to the 9:16 phone resolution making a square video more pleasant to watch and to be featured in in-feed videos.

9:16 Vertical

The 9:16 aspect ratio has become the mainstream resolution for smartphones for easier viewing of videos. This resolution allows for the vertical display of videos on tablets and phones, meaning that it allows videos to play while the device is being held in its upright position. This works ideally for Facebook, Instagram, Snapchat, YouTube Shorts, and more.

4. How to adjust the aspect ratio of a video?

A very important point we’d like to mention is that we don’t recommend changing the aspect ratio after filming, because it could harm the video quality and we think it’s best to choose the aspect ratio on your phone or camera before filming, besides that we have some great tips for optimizing your video for the watching experience below.

Black bars

When editing your video, adding black bars is not changing the aspect ratio as you are just adding black bars to the screen. What we do recommend is cropping the video until you get the desired result. Adding black bars won’t automatically make the platform adjust the video and it will affect the viewer experience.

Cropping

Cropping your video will allow you to remove a section from your video, which works perfect for unwanted objects or people. While cropping the video, you are forced to pick the essential part of your video and disregard the rest of the video and to remove distraction from the frame.

Conclusion

Having your video tested on multiple devices will allow you to see a preview of what the viewer will see and make necessary changes if needed. When your video looks perfect, you can be sure that it will give a seamless experience across all platforms, without the fear of losing video quality.
