Zoom offers a free plan that allows users to host meetings with certain limitations. For users on the free plan, Zoom permits a single meeting to last up to 40 minutes. This time restriction applies to group meetings with three or more participants. If the meeting is between just two people, there is no time limit, and the session can continue indefinitely. However, once the 40-minute limit is reached in a group meeting, the session will automatically end, and participants will need to start a new meeting if they wish to continue. In summary, Zoom's free plan allows group meetings to last up to 40 minutes, while one-on-one meetings can go on without any time constraints.
