Videos are the lifeline of today’s content, both offline and online. However, it also means that it only takes a couple of seconds before viewers consider content worth watching or not. Everything needs to be shown clearly and in high quality, which can only be possible if you’re using the correct video aspect ratios for your content. 

If you want to learn more about video aspect ratios and go beyond just looking at several numbers, get to know what’s behind these numbers and how you can use them to your advantage in improving the aesthetics and viewing experience of your audience. 

Defining Video Aspect Ratio

The term “video aspect ratio” refers to the two numbers that depict the height and width of the video content. These two measurements in the ratio pertain to the dimension of the video frame and are depicted by the following format “X:Y,” which points to the width and the height of the video frame. 

It is essential that you use the appropriate aspect ratio because if you choose wrongly, you’ll end up with distorted content, which can come in different forms, including the following:

• Stretched content
• Compressed content
• Cut-off text and images
• Distracting black bars

All of these factors can worsen the performance of your content and lower the interest of viewers in the process. All of which can be avoided if you choose the right video aspect ratio. These video aspect ratios need to be compatible with the ratio of the LED screen to work well.
