How many minutes of video calls happen on Zoom each day?

How to get close to this number

Multiply meetings by length by users. A platform with hundreds of millions of participants, most joining one or two meetings a day of roughly half an hour to an hour, produces billions of participant-minutes. The unit is the clue: minutes are counted per participant, so a ten-person hour-long meeting contributes six hundred.

The growth in the explanation is the historically significant part: roughly thirty times the pre-2020 figure, achieved within months. Very few technologies in history have seen demand multiply by that factor that quickly, and the infrastructure scaling required to absorb it without collapsing is a genuine engineering achievement rarely credited.

The durable half is that usage never returned to the old baseline. A step change forced by circumstance became a permanent change in how work is organised, which is the more consequential fact — the interesting statistic is not the peak but the floor it established. A temporary shock that resets a norm is rarer than one that fades.
