How Much Data Does a Zoom Meeting Use?

Whether we like it or not, Zoom has pretty much become a part of our daily lives. In fact, I have to hop on a Zoom call in about 20 minutes, so let’s answer this question quickly. Just kidding (but I really do have the meeting).

To avoid your face freezing midconversation and your voice suddenly remixing into a weird Daft Punk song, you’ll want sufficient internet data for your Zoom conversations to run smoothly. Let’s answer how much data does a Zoom meeting use.

Per Zoom’s website, here are all the internet bandwidth requirements for different activities on Zoom

For 1:1 video calling:

• • • 600kbps (up/down) for high quality video
    • 1.2 Mbps (up/down) for 720p HD video
    • Receiving 1080p HD video requires 1.8 Mbps (up/down)
    • Sending 1080p HD video requires 1.8 Mbps (up/down)

For group video calling:

• • • 600kbps/1.0Mbps (up/down) for high quality video
    • Gallery receiving view: 2.0Mbps (25 views) and 4.0Mbps (49 views)
    • 1080p HD video requires 3.8Mbps/3.0Mbps (up/down)
    • 720p HD video requires 2.6Mbps/1.8Mbps (up/down)

For screen sharing only (no video thumbnail): 50–75kbps

• • • For screen sharing with video thumbnail: 50–150kbps
    • For audio VoiP: 60–80kbps

For webinar attendees: 

• • For panelists with their video on:
    • High-quality video: 600kbps 
    • 720p HD video: 1.2-1.8Mbps(down)
    • 1080p HD video: 2-3Mbps
  • Screen sharing only (no video thumbnail): 50-7kbps(down)
  • Screen sharing with video thumbnail: 50-150kbps(down)

For Zoom Phone: 60–100kbps

That was a lot of technical jargon above, so let’s make this information a bit more digestible. Here’s a breakdown of internet speed measurements.

• • • 1 megabit (MB) = 1000 kilobytes (Kb)
    • 1 megabyte (MB) = 8 megabits (Mb)
    • 1 gigabyte (GB) = 1,000 megabytes (MB)

Now that we’ve got an idea of the measurements, let’s take a closer look at how much data Zoom uses depending upon the quality of your stream, and how many people are in the meeting.

You use somewhere between 540 MB and 1.62 GB per hour (between 9 MB and 27 MB per minute) for a 1:1 Zoom meeting, depending upon the streaming quality.

Your Zoom data usage jumps up with more people on the call. Group Zoom meetings take up somewhere between 810 MB and 2.4 GB per hour, or between 13.5 MB and 40 MB per minute.

To put those numbers in context, take a look at how much data is used for other everyday activities.

Zoom streaming is fairly comparable to normal video streaming, but since upload speeds are part of the equation, a Zoom stream does take up more data than streaming Netflix.

If your internet is having a hard time keeping up with Zoom calls, then you might want to see what other options are available in your area. You might be paying too much for a lousy internet connection, and there might be some better options for you. Our internet expert Catherine recommends Xfinity internet as the best internet provider.
