Millions of people around the world register on YouTube out of watching versatile videos, sharing favorite videos with friends and also uploading self-made videos to YouTube. Uploaded videos could involve travel recording, product introduction, how-to guide, promotional tour, etc. However, not all videos you upload to YouTube can deliver satisfactory viewing experience. Uploaded videos may always end up with black bars on the sides or low video quality. To rectify things like these, you need to figure out the best YouTube size.

When uploading video to YouTube, it's necessary to check ahead if your video size matches with the requirements of YouTube video uploading.

1. Video File size for YouTube
According to the rule, video file size is limited to 2GB for YouTube uploading. But size larger than 20GB is allowed by using an up-to-date browser. And the maximum is 128GB.

2. Best video frame size for YouTube
Video frame size refers to video resolution. Since YouTube applies 16:9 aspect ratio players, uploading a 16:9 video file could be the best choice. The following resolution plans are the frequently-used ones.
