As a streaming business, your goal is to captivate your audience. And selecting the best aspect ratio is a crucial aspect of achieving this objective. From widescreen 16:9 to traditional 4:3 and even vertical formats, each aspect ratio has its own unique effect on how your content is perceived and experienced.
We will delve into the details of each aspect ratio, examining their applications and advantages in various streaming platforms. Furthermore, we will explore how aspect ratios contribute to maintaining visual consistency across different devices, ensuring that your content retains its intended impact, regardless of the viewing platform.
So, let’s get started!
Video aspect ratios refer to the proportional relationship between the width and height of a video frame. It represents the shape or format of the video display. Aspect ratios are expressed as a ratio of two numbers, typically separated by a colon. The first number represents the width of the video frame, while the second number represents the height.
To get the aspect ratio from a video resolution, you have to simply divide the width by the height. For instance, if the video resolution is 1920 px by 1080 px, then the aspect ratio will be 16:9.
Note that, for a single aspect ratio there can be multiple video resolutions.
I,e. for 16:9 aspect ratio, the possible resolutions are-

Video aspect ratio is a fundamental aspect of visual storytelling, playing a crucial role in the composition and presentation of video content. Historically, aspect ratios have evolved alongside advancements in technology and changes in visual media.
In the early days of cinema, the standard aspect ratio was 4:3, known as the Academy ratio. This ratio was inherited from the aspect ratio of 35mm film stock and became the industry standard for both film and television.
However, with the rise of widescreen formats, such as CinemaScope, a new aspect ratio emerged – 2.35:1. This wider aspect ratio allowed for a more immersive cinematic experience and became popular in the film industry.
In the 1950s and 1960s, television sets started to adopt a wider aspect ratio of 16:9, known as the widescreen or HDTV (High-Definition Television) aspect ratio. This aspect ratio became the standard for high-definition content and is now widely used in modern displays and streaming platforms. Today, aspect ratios vary depending on the intended platform and purpose of the video content.
Lets now take a quick look at some of the most commonly used video aspect ratios.
The standard aspect ratio, also known as 4:3, was the traditional aspect ratio for television and computer monitors. It has a nearly square shape, with the width being four units and the height being three units.
This ratio was prevalent in older CRT televisions and earlier digital displays. It is still used in specific contexts, such as retro-themed videos or certain broadcasting formats.
The widescreen aspect ratio, commonly referred to as 16:9, has become the standard for high-definition video content. It offers a more cinematic widescreen viewing experience compared to the standard ratio.
With a width of 16 units and a height of nine units, this aspect ratio is widely used in television, streaming platforms, online videos, and modern displays. It provides a visually immersive experience and is compatible with most devices and screens.
The ultra-widescreen aspect ratio, often denoted as 21:9, offers an even wider and more expansive viewing experience compared to the widescreen ratio. It is commonly used in cinematic presentations and gaming monitors.
With a width of 21 units and a height of nine units, this aspect ratio provides a panoramic view and enhances the cinematic feel of videos. However, it may require special formatting and is not universally supported by all platforms and devices.
The square aspect ratio, represented as 1:1, has equal width and height dimensions. This ratio is popularly used in social media platforms like Instagram. It is well-suited for mobile viewing and sharing and is often used to showcase products or capture attention in social media feeds.
The square format offers a balanced and symmetrical composition, allowing content creators to focus on central elements within the frame.
The vertical aspect ratio, denoted as 9:16, is specifically designed for vertical or portrait-oriented videos. It is commonly used in platforms like TikTok and Snapchat, where users primarily view videos on mobile devices in a vertical orientation.
This ratio provides an optimized viewing experience for mobile users, allowing content to occupy the entire screen in portrait mode.
While standard aspect ratios are widely used, there are instances where custom aspect ratios are necessary. Custom ratios can be tailored to specific project requirements, accommodating unique screen dimensions or creative choices.
Content creators can define the desired width and height dimensions to create a custom aspect ratio that suits their vision.
The full frame ratio refers to a 3:2 aspect ratio commonly found in photography. It is based on the dimensions of standard 35mm film frames. This aspect ratio is often used in slideshows, presentations, or videos that aim to emulate the look and feel of traditional film photography.
Panoramic aspect ratios, such as 2.35:1 or 2.39:1, are commonly used in film production to create a wide, cinematic view. These ratios provide an expansive visual experience, emphasizing sweeping landscapes or grandiose compositions.
Panoramic ratios are often associated with epic movies or high-budget productions, capturing the viewer’s attention and creating a sense of awe and immersion.
CinemaScope aspect ratio, specifically 2.35:1 or 2.39:1, is a widescreen format that was popularized in the 1950s. It was developed to provide a wider cinematic experience compared to the standard 4:3 aspect ratio.
CinemaScope offers an immersive viewing experience, with a wide horizontal span that fills the audience’s field of vision. This ratio became synonymous with epic films and is still used in modern cinema to create a sense of grandeur and spectacle.
The significance of different aspect ratios lies in their ability to convey specific visual experiences and evoke different emotions. The choice of aspect ratio depends on various factors, including the intended platform, target audience, and the creative vision of the content.
When it comes to video streaming and Over-The-Top (OTT) platforms, choosing the right video aspect ratio is crucial for delivering a seamless and immersive viewing experience. Let’s explore some of the best video aspect ratios for video streaming and OTT platforms.
It offers a cinematic viewing experience and is compatible with modern high-definition displays. This aspect ratio is widely supported across different devices and platforms, making it an ideal choice for delivering content to a broad audience.
