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.

Zoom internet recommendations

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:

      • 800kbps/1.0Mbps (up/down) for high quality video
      • For gallery view and/or 720p HD video: 1.5Mbps/1.5Mbps (up/down)
      • Receiving 1080p HD video requires 2.5mbps (up/down)
      • Sending 1080p HD video requires 3.0 Mbps (up/down)

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

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

How much data does a Zoom call use?

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.

What’s the difference between download and upload speeds?
You need both download and upload speeds to run Zoom. Your download speeds affect what you can see, and upload speeds affect how other people on the call can see you. The higher your upload speeds, the smoother you’ll broadcast yourself to other people on the call. The higher the download speeds, the more clear you’ll be able to see and hear everyone else on the call.
Zoom data usage for a 1:1 meeting
High270 MB/hr.270 MB/hr.540 MB/hr.
720p540 MB/hr.540 MB/hr.1.08 GB/hr.
1080p810 MB/hr.810 MB/hr.1.62 GB/hr.

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.

Zoom data usage for a group call
High450 MB/hr.360 MB/hr.810 MB/hr.
720p675 MB/hr.675 MB/hr.1.35 GB/hr.
1080p1.2 GB/hr.1.2 GB/hr.2.4 GB/hr.

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.

Data usage for common activities
ActivityAmount of data used
4K video streaming5.85 GB/hr.
HD video streaming2.5 GB/hr.
SD video streaming0.7 GB/hr.
Audio streaming72 MB/hr.
Uploading one image to social media5 MB/photo
Sending emails (without attachment)20 KB/email
Sending emails (with standard attachment)300 KB/email
Online gaming12 MB/hr.
Viewing a web page1 MB/pg.

Based on AT&T data calculator estimates. Amounts may vary.

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.
