The quality of your home or mobile network can affect how smoothly YouTube videos play, and whether videos play in HD.

Check the YouTube video's resolution and the recommended speed needed for the video to play. The table below shows the approximate speeds recommended to play each video resolution. If your internet speed is below the requirement, you will fail to play YouTube video.

Video Resolution Recommended sustained speed
4K 20 Mbps
HD 1080p 5 Mbps
HD 720p 2.5 Mbps
SD 480p 1.1 Mbps
SD 360p 0.7 Mbps

The actual speed that your device gets may vary from the number given when you run an 'internet speed test.' The difference can be due to numerous factors including:

  1. Wi-Fi performance
  2. Time of day
  3. How your ISP connects to YouTube
  4. How many devices are on your network: If there are a few devices on your network, then the connection is shared between them. Using numerous devices on the same network may reduce the speed that your device gets.

You can try to improve your internet from the factors above.
