Frequently asked questions
An HD one-on-one Zoom call uses about 0.81 GB per hour. A group HD call uses around 1.35 GB per hour. Audio-only calls are very light at just 0.04 GB per hour.
At HD quality, 10 hours per week uses about 8.1 GB weekly or 35 GB monthly. Switching to SD reduces that to 2.7 GB weekly (11.7 GB monthly) - a significant saving for limited data plans.
They are comparable. Both use 0.7-1.0 GB per hour for HD one-on-one calls and 1.2-1.5 GB per hour for group calls. Google Meet falls in the same range. The difference is usually less than 15%.
Turn off your camera when you do not need it - audio-only uses 20 times less data than HD video. You can also lower the video quality in your app settings or close other bandwidth-heavy applications during calls.
Zoom recommends 3.8 Mbps up/down for HD one-on-one and 3.0 Mbps up with 2.5 Mbps down for group HD. Most broadband connections handle this easily. Mobile hotspots may struggle with group HD calls.
