Here’s a look at what might cause your videos to look wrong, and how to use YouTube codes to fix the issue.

Causes for YouTube Videos Not Displaying Correctly

Usually, the culprit for a video displaying with black bars, a stretched or squished appearance, or poor video quality is using an incorrect aspect ratio. When the aspect ratio doesn’t align with the YouTube video player, black bars or other problems occur. YouTube used to abide by a 4:3 aspect ratio, which was the same as standard-definition TVs in the U.S. YouTube now uses a 16:9 aspect ratio, which is also the aspect ratio for modern HDTVs. This is also commonly known as widescreen. Any video uploaded to YouTube that doesn’t fit into a 16:9 ratio displays either cropped or with bars.
