The number of participants that can join a WebEx meeting depends on the type of WebEx account the host uses, how participants decide to join, and how meetings are scheduled. If the host has a free account, then a maximum of 25 participants can join the meeting. However, if they use a paid version of WebEx, such as WebEx Calling, up to 100 participants can attend. Additionally, if the host is using a paid Meetings account, they can host up to 200 people in a meeting.
