How Much Data Does YouTube Use?

If you have a monthly bandwidth limit on your cellular data plan, it’s important to know how much data YouTube uses. How much data YouTube uses is dependent on the quality of the video you’re streaming. According to YouTube itself, YouTube uses the following amount of data on iPhone or iPad:

  • For Standard Definition, YouTube uses about 1 GB of streaming data per hour.
  • For High Definition, YouTube uses about 3 GB of streaming data per hour.

To be exact, Netflix uses 0.9 gigabytes of data per hour for standard definition video quality, but rounding that number up to 1 GB is an easy way to make sure you don't go over your alloted amount of YouTube data usage.
