Features Of 16:9 Screen
16:9 Ratio Defined
A 16:9 ratio (pronounced “16 9”, “16 to 9”, or “16 by 9” and sometimes written as “16×9”) is an aspect ratio, 16 inches wide by 9 inches high, 32 widgets wide by 18 widgets high, where for every 16 units of width, there are 9 corresponding units of height.

16:9 is significant because it is today’s standard ratio for film and display. The 16:9 ratio replaced the old 4:3 ratio in the early 2,000s. You may have heard terms such as 1080p HD, 720p HD, and 4K UHD. These terms all refer to 16×9 ratios.
16:9 Ratios and Vedio Walls

In many cases, video walls will be built into the 16:9 format to allow for seamless display of 16:9 content.
LED PANEL COUNT AND 16:9 RATIOS
Square (1:1) LED panels may pose a challenge when creating true 16:9 video walls, because the only way to achieve an exact 16:9 ratio is to have 16 panels wide by 9 panels tall, or an exact multiple of such. Luckily, there is some wiggle room with 16:9 ratios. You want your video wall to be close to a 16:9 ratio and the 16:9 content will automatically stretch to fit the display. Display quality can be affected by Pixel Pitch as well.
Aspect Ratio on TV
Nearly all channels in European, American, African, Asian, and other countries have their default TV resolution at 16:9. It is by far the standard screen size when viewing and distributing Television broadcasts. Wikipedia has a great resource displaying all countries along with the default aspect ratio that their Television distributions use.
Conclusion
16:9 ratios are an aspect ratio containing 16 units of width for every 9 units of height. They can be calculated by ensuring that width divided by height equals 1.78.
16:9 ratios are important to understand when selecting a video wall size or designing content for video walls.
