In the display world, aspect ratio is king. While your screen’s orientation still dictates how comfortable you’ll be, its aspect ratio ensures the display isn’t too wide or too tall so the images get distorted. This post will look at what 16:9 is, its history and why it’s used on film, TV and online content.
What is 16:9?
Like what you learned in Math, ratio is the relationship between two numbers. In this case, it’s the relationship between the screen width (first number) and height (second number). For screens with a 16 by 9 ratio, it means they’re 16 units long and 9 units wide.
Aspect ratio determines how visual content is framed and seen. Different aspect ratios evoke different emotions and experiences, so it’s important for filmmakers, video producers and content creators.
History of 16:9
16:9 has a long history dating back to the 1980s when it was introduced as a compromise between the multiple aspect ratios used in different media. Here’s a quick rundown:
- 1980s: 16:9 was born as a middle ground between 4:3 and 21:9 aspect ratios used in film and TV.
- 1984: Japan was the first to adopt 16:9 with the introduction of Hi-Vision, an early analog high-definition TV system.
- 1990s: 16:9 went global with the rise of digital TV and DVD formats that supported widescreen viewing.
- 2007-2009: The switch from analog to digital broadcasting hastened the adoption of 16:9 worldwide.
- 2009: 16:9 was the norm for TVs and monitors.
- Today: It’s the standard for digital TV including HDTV and online video.
It’s popular because of its flexibility and compatibility with both film and TV.
The Basics
16:9 is also known as the widescreen aspect ratio. It’s used for HD and UHD content and gives you a wider field of view. Technically 16:9 can be expressed as 1.78:1 meaning the width is approximately 1.78 times the height. It’s a middle ground between the immersive qualities of widescreen formats and the practicality of screen dimensions so it’s the best for many applications.

This versatility of use proves that 16:9 is the standard for modern media consumption.
Aspect Ratio Conversion
Aspect ratio conversion is needed to keep content intact and looking good across different display formats. This is when the original aspect ratio doesn’t match the display device’s native aspect ratio and the image gets cropped or stretched. By converting aspect ratios content creators can preserve the composition and get a consistent experience across platforms.
To Other Ratios
16:9 can be converted to other common ratios like 4:3 or 1:1 depending on the project requirements or the platform specs. For example, 16:9 is good for widescreen displays but 4:3 might be needed for older TV sets or certain mobile apps. So content can be repurposed for different viewing environments without losing the core visual elements.
With Other Ratios
When reconciling 16:9 with other formats black bands (often seen as letterboxing or pillarboxing) are used. The black bands on the screen allow images to be displayed on the screen without altering their original appearance. So the content’s composition remains true to the creator’s vision even when displayed on different sized screens.
Compared to Old Ratios
The evolution of aspect ratios is clear when you compare the modern 16:9 widescreen to the old 4:3 aspect ratio which was the standard for TV and film. 4:3 was the norm in the early days of TV and is still used in some specific cases but the shift to 16:9 is the industry’s move towards a more cinematic and immersive experience. This transition shows the change in media consumption and the industry’s response to new technology and audience expectations.
Which One to Choose
Choosing the correct ratio is crucial in ensuring your audiences can view your content the way you intend them to. Different aspect ratios can make you feel different, frame your subject matter in different ways, and influence how the audience engages with your work. Knowing this allows content creators to choose an aspect ratio that matches the narrative and visual goals of their project.
Consider your project:
- If your project is character-driven, where close-ups and facial expressions are important, 4:3 might be the way to go.
- If the setting is a key part of the story, creating a sense of space or scale 16:9 might be the way to go for wide landscapes or action sequences.
Most Common Ratios
- 16:9: The format for videos, TV screens, and computer monitors.
- 4:3: Used for close-ups and portraits and older media formats.
- 1:1: Popular on social media platforms like Instagram, for centered and visually appealing content.
Other Aspect Ratios
The popularity of social media content creation signaled the arrival of vertical aspect ratios that fit the average smartphone screen. These vertical aspect ratios match how we hold our phones, creating a more seamless and engaging experience for mobile viewers.
Common Vertical Ratios
- 1:1: Instagram’s default ratio, good for square images and content.
- 18:9, 19:9, 20:9, 21:9: These ratios on modern smartphones give you a bigger screen and a cinematic feel.
Screen Dimensions and Area
Specifications
Screen dimensions are usually given by the diagonal, but to work with different aspect ratios, you need to know the height (h), width (w), and area (A) of the screen. Knowing how to calculate these dimensions will ensure your content fits the screen without distortion.
The Formula
To maintain a 16:9 ratio, the quotient of the screen’s width and height must be 1.778 (16/9).
The aspect ratio is 16:9 (also 1.78:1) if W/H is roughly 1.778.
Calculating Height from Width:
Simply divide the width by 1.778
Sample Problem:
Vince wants to put up an LED wall that’s 32-panel-wide. How many panels high should the screen be for it to follow the 16:9 ratio?
- Step 1: Use the aspect ratio formula:
- W/H=1.778
- Step 2: Substitute the width (W = 32) into the equation:
- 32/H=1.778
- Step 3: Solve for the height (H):
- H=32/1.778
- Step 4: Calculate:
- H≈18
Vince’s video wall should be 18 panels high to keep a 16:9 aspect ratio.
Calculating Width from Known Height
With the height given, you can find out the unknown width by multiplying it by 1.778.
Sample Problem:
Harvey is designing a social media post that is 720 pixels tall. What is the perfect width for the design to be 16:9-compliant?
- Step 1: Use the aspect ratio formula:
- W/H=1.778
- Step 2: Substitute the height (H = 720) into the equation:
- W/720=1.778
- Step 3: Solve for the width (W):
- W=720×1.778
- Step 4: Calculate:
- W≈1,280
To keep the 16:9 aspect ratio, Harvey’s image needs to be 1,280 pixels wide.
Number of Panels Required
When designing a video wall, especially with the common 16:9 aspect ratio, it’s important to configure the panel layout correctly. Displays with a 16:9 aspect ratio guarantee a seamless visual experience.
Panel Configuration for 16:9
Creating a 16:9 video wall with square (1:1) LED panels is tricky. Ideally, the grid should be 16 wide and 9 high or be a multiple of these dimensions. However, the 16:9 safe zone offers some flexibility, allowing for slight variations without compromising visual quality.
To check if your video wall is within this safe zone you can use the following formula:
Panel Count Formula for 16:9 Ratio:
Panel Width/Panel Height≈1.65-1.85
If the width divided by the height of your panel grid falls within this range your video wall will be 16:9 and any deviation will be imperceptible to the viewer. For example:
- 16 panels wide by 9 panels high: This is a perfect 16:9 ratio.
- 14 panels wide by 8 panels high or 18 panels wide by 10 panels high: These also work within the acceptable range.
Video Walls with Different Panel Types
If you have panels that are already 16:9 like some LCD video panels the overall aspect ratio of the wall remains the same regardless of the panel count. For example:
- 2×2, 5×5, or 10×10 with 16:9 panels: These are 16:9 because the panels scale up without changing the overall display ratio.
16:9 Content on Non-16:9 Screens
Sometimes you may need to display 16:9 content on a video wall that’s not 16:9. This can be due to last-minute content changes or if your video wall has a custom aspect ratio. In this case, there are three ways to adapt the content:
- Stretch to Fill: This option stretches the content to fill the screen ratio, which can cause distortion, especially with shapes like circles. Stretching is okay if the distortion is low, usually below 10%.
- Letterbox: This method keeps the content’s original ratio by fitting it proportionally within the screen and adding black bars on either side of the screen and content ratios are different. This preserves the content without distortion.
- Crop to Fill: This option fills the screen by cropping the image, which can cause a loss of important details near the edges. This works for visual content only, not for content with critical information near the margins.
Which one to choose depends on the content and the visual outcome you want for your video wall. These options help you maintain display quality and have your content look as intended.
