How much data do Teams and Zoom use?

How much data Microsoft Teams and Zoom use depends on whether you use audio, video or screen sharing and the video quality of the meeting.

Approximate data usage:

  • Audio only: about 50–100 MB per hour
  • Video call in normal quality: about 0.5–1 GB per hour
  • HD video: about 1–2 GB per hour
  • Group meetings with several video streams: can use 2 GB or more per hour

Want to save data?

You can reduce data usage by:

  • switching off the camera when you do not need it
  • avoiding HD video
  • switching off incoming video if the connection is weak
  • using audio only in longer meetings

Remember that both download and upload are used in a video meeting, as you both receive and send sound and picture.
