A decade ago, did you recall DVD’s with the choice of full or large screen viewing options? Do you remember that?

You have probably found that the part of the movie was cut off or too much black was padded around if you selected the wrong choice.

The standard size of the TV’s ranged from a 4:3 width to a much wider height ratio. Producers started making films for both screens.

As the viewing aspect ratios become more standardized, the video aspect ratio and the width to length of the videos now take care of both broadcasters and the content creators.

Today, we'll break down the exact aspect ratios, widely used ratios, and video resolutions, and their role in live video streaming.

The user experience of streaming live video is influenced by many factors. Professional audio, sharp graphics, perfect lighting, and other film content are usually taken off the bat, but aspect ratios are always secondary.

When you create and broadcast video content for your viewers, the aspect ratio of your video needs to be taken into account. We are breaking down video aspect ratios today and discussing the role they play in video streaming.

Live video streaming ratios

What is the relationship between video and aspect?

The display aspect ratio shows the video orientation by having a pixel width to height ratio. The numbers shown in the ratio do not always show the height and width of the pixels (px). It is just the ratio of width to height.

A 16:9 video, for instance, is not 16 px wide and 9 px large. You can't see such a tiny video. The aspect ratio is 1920 px by 1080 px with one resolution of 16:9.

Ratio and resolution aspect

Several counterpart resolutions exist for each aspect ratio. The ratio of aspect and resolution go hand in hand.

You must increase the width by the height to get the resolution; so divide the width by the height to get the aspect ratio.

You get the number of square pixels on the screen when you multiply the width by the height. The higher the higher the higher is the better!

Often, it is possible to choose a lower quality. If you need smaller file sizes, a lower-quality video will be useful. Here, you can record your video with the highest quality and will make lower-resolution copies of the video with encoding software.

Ratios and uses of the common aspect

In the video aspect ratios, there are no single-size fits-all. Aspect ratios are generally selected based on the positioning, viewing, and function of the film.

Social media videos can differ from theatrical movies or previews. There are common aspect ratios for modern TVs, but the aspect ratio that is ideally suited to their content and audience is free for broadcasters.

Since most videos are transmitted via standard online video platforms, individual aspect ratios are not frequently employed.

Here are some typical look ratios you can use to stream live and create other videos:


A 16:9 aspect ratio video is a wide rectangle. It is also called "1.71:1," mathematically speaking the most simplified version of the ratio.

Today, for most of your video production and streaming, you're likely to use the 16:9 aspect ratio since the 16:9 is considering a common international format for TV, movies, and large online streaming platforms.

This aspect ratio is also used by many when they often live on their pages.

16:9 is the norm for most technical and consumer-grade video capture systems. The size for video players is also the most popular. There are many explanations why 16:9 is the norm. Screens of this scale provide higher resolution than the 16:10 aspect ratios used to be the international standard. It is also more economical than their predecessors to produce displays consistent with this ratio. Standardization of TVs and computer displays saved time and money for producers in testing. A sequence of 16:9 is 4K, or 4096 px is one of the highest resolutions.


The 1:1 aspect ratio is a wonderful place and was used for square TV sets.

The aspect ratio of 1:1 is now much less frequently used. You will find it most effectively on social media sites like Instagram or Facebook.

Although it is not the most used aspect ratio, a square setting still exists in many cameras.


For conventional television and computer displays, the 4:3 aspect ratio was normal before 16:10 and 16:9. The explanation was that HDTV had been born. The aspect ratios 16:10 and 16:9 are higher than 4:3.

Until they released the 2018 iPad Pro this aspect ratio was still used by Apple IPad. The aspect ratio 4:3 is gradually removed and therefore not very general.


In the first case of 35 mm silent film, the 3:2 aspect ratio was used. Notebooks, tablets, and portable game consoles are also used. Many mini- to medium-sized cameras still have the 3:2 aspect ratio configuration, but today broadcasters seldom use it.


The aspect ratio of 21:9 is very specific. It is also known as an ultra-wide-screen or a movie broadcasting. It is used in anamorphically formatted films. Videos in anamorphic format are used to create a 360-degree view of an optical illusion.

In special theatres, museums, theme parks, and others, you are likely to find videos with this aspect ratio. They are meant to provide audiences with more intimate experiences.

The illusion of these screens is designed to feel as if you are in the video instead of seeing the video.


Lange videos are shot with a 9:16 aspect ratio. As smartphones with video capabilities were introduced, this aspect ratio gained popularity.

For example, the ideal size for an Instagram story is 1080 px by 1920 px, which means the ratio is 9:16. The same can be said for other famous apps with "plot" features, such as Facebook and Snapchat. This makes sense because the iPhone camera's video setting can capture footage in both 9:16 and 16:9 ratios.

How to Determine a Video's Aspect Ratio

Many video cameras have a range of look ratio configurations. This helps you to choose the aspect ratio of your video before recording it.

You can obtain additional information for the file if you are attempting to determine the aspect ratio of a previously recorded video. The information button on a Mac is a tiny I in a circle. On a PC, right-click a file and choose "Properties." You can split the video's current width and height, however, to find the aspect ratio.

What is the video's best aspect ratio?

Video size is 16:9 the most common aspect ratio, but, the optimal aspect ratio is not this.

This is so popular because it is the norm for TVs and popular streaming channels such as Diecast, Brightcove, Youtube, TikTok, or Netflix. A 16:9 ratio is usually considered optimum as the highest resolution is capable. This aspect ratio on nearly all devices is also easy to catch. Take into account its intent and location to decide which video aspect ratio is best for your content.

How to change the video aspect ratio

There are two options for changing the aspect ratio of your video: add black bars to or crop the video.

Although the aspect ratio of your video can be changed after filming, it is not always advisable. Since the downfalls of both approaches are. You need an editing tool with cutting capability if you want to take the way to save your video. If you aim to increase the size of the video, cutting could remove important individuals or items. You will select the most important parts of the frame and lose the rest.

Live Streaming Video Aspect Ratios

Live transmissions are difficult to figure out before you film, as the public absorbs the content made. You need to find out logistics before you film.

Also you must obey the video streaming protocol that needs two things: uniform playback and small file size, to provide a video aspect ratio.

You can cross the two with the 16:9 aspect ratio. You may select a variety of resolutions to find the best compromise where the desired quality and file size match. Essentially any monitor, TV, mobile device, and the video player will play 16:9-specific videos, thus also ensuring universal playback.

It is really important to make sure that your recording device's video aspect ratio is compatible with your chosen streaming platform when you broadcast live. You don't want something valuable, especially as you're not going to have the chance to redefine the material.

Creating Video Contents Aspect

When producing video material to be transmitted to your audience, look ratios — the ratio of video width to length — definitely take account of. While it is of great importance to have a compatible video aspect ratio and video hosting manager or streaming services, you have to take the user experience into account.

Consider the kind of devices your viewers are going to use to view your videos and decide accordingly.

If you want a 16:9 aspect ratio for material that can be streamed to the computer or a 9:16 ratio that can be streamed to the mobile phone, make sure that it is transparent and tasteful for your audience.
