By default, every Zoom account comes with a maximum of 50 breakout rooms. This enables hosts to split attendees into 50 groups. The size of these groups depends on your total meeting attendance.
Depending on your meeting attendance and the number of guests you wish to have in each group, you may need to request an increase to the number of breakout rooms in your account. At this time, Zoom allows you to manually request an increase of up to 100 breakout rooms.
The number of breakout rooms you will require is determined by two factors:
The total number of meeting guests in your meeting
The number of guests you wish to be in each breakout room
The number of breakout rooms you will require is equal to:
# Of Breakouts Required = Total Number of Meeting Guests / # of Guests Per Room
For example, if you had 100 total meeting guests and you wanted them split up into groups of 2 (i.e 1-on-1 matching), you would require 50 breakout rooms.
If you had 200 total meeting guests and you wanted them split up into groups of 2 (i.e 1-on-1 matching), you would require 100 breakout rooms
In the second scenario, you would need to contact Zoom and have them increase the maximum number of breakout rooms on your account.
Here are some other examples:

If your number of breakout rooms required exceeds 50, you can request an increase to the number of breakout rooms on your account here.
