What Internet Speed Do I Need for Zoom?

Zoom is the most reliable video conferencing platform, but it’s only as good as the internet speed you give it. You’ll want at least somewhere between 150 Kbps and 1.1 Mbps dedicated to Zoom to run a smooth call.

What Internet Speed Do I Need for Zoom?

According to Zoom’s website, these are the internet bandwidth requirements for different kinds of Zoom calls.

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

For Zoom Phone: 60–100kbps

Just for reference, here’s how data measurements break down:

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

We’ll spare you the maths and give you an idea of how much data Zoom uses per hour and per minute, rather than a per-second basis. I don’t know about you, but my Zoom conversations rarely last only a few seconds (though it would be nice if they did sometimes).

Zoom data usage for a 1:1 meeting

720p540 MB/hr.540 MB/hr.1.08 GB/hr.
1080p810 MB/hr.810 MB/hr.1.62 GB/hr.

On a 1:1 Zoom meeting, expect to use between 540 MB and 1.62 GB per hour, or somewhere between 9 MB and 27 MB per minute. To put those numbers in internet-speed terms, you’d want an internet speed between 150 kbps to 450 kbps to smoothly run a Zoom 1:1 call.

Wait, that’s not much internet speed at all.
It’s true that a 1:1 Zoom call on its own doesn’t need a ton of internet speed to run well, but keep in mind that your internet speed doesn’t just dedicate itself to Zoom calls. Your internet bandwidth has to allocate internet to all of your devices at once.

720p675 MB/hr.675 MB/hr.1.35 GB/hr.
1080p1.2 GB/hr.1.2 GB/hr.2.4 GB/hr.

The bigger the Zoom meeting, the more data it uses. For every hour of a Zoom group call, you use between 810 MB and 2.4 GB, or somewhere between 13.5 MB and 40 MB per minute. You’ll need an internet connection of at least between 225 kbps and 670 kbps dedicated to the Zoom call.

Keeping in mind that your internet bandwidth goes to all of your internet devices at the same time, here are some examples of other common data usages that probably are happening at your home.

Not enough internet for Zoom calls?

A laggy Zoom call sort of feels like a bad first date. You can’t really connect with each other, it feels awkward, and everyone just wants it to end. If your internet connection struggles maintaining a smooth Zoom call, it might be time to consider upgrading your internet. Our internet expert Catherine recommends Xfinity internet as the best internet provider out there.
