The Zoom meeting participant limit is 100 on Zoom's Basic and Pro plans and 300 on Business, according to Zoom's own plan page. Basic meetings also stop at 40 minutes, while Pro allows 30 hours. Larger audiences go through webinars, which Zoom lists at up to 500 attendees on its standard webinar page.
If you're planning a workshop, a client briefing or a community call, the headcount question comes first. Here's every Zoom cap that affects how many people you can get into the room, and for how long, as listed on Zoom's own pages as of Nov 2026. These can change, so check the plan page before a big event.
Zoom's meeting and webinar caps at a glance
| Item | Limit | Applies to |
|---|---|---|
| Participants per meeting | 100 | Zoom Workplace Basic |
| Participants per meeting | 100 | Zoom Workplace Pro |
| Participants per meeting | 300 | Zoom Workplace Business |
| Meeting length | 40 minutes | Zoom Workplace Basic |
| Meeting length | 30 hours | Zoom Workplace Pro |
| Webinar attendees | Up to 500 | Standard webinar platform, per Zoom's webinar page |
| Webinar broadcast audience | Up to 10,000 | Webinar feature, per Zoom's developer docs |
| Registrants per meeting | 4,999 | Meetings API registration |
| Scheduled meetings per user per day | 100 | Across all Zoom apps, per Calendly's Zoom troubleshooting page |
Two things jump out. Moving from Basic to Pro doesn't raise the headcount: both list 100. What Pro changes is the length, from 40 minutes to 30 hours. The jump in seats comes with Business, at 300.
What happens when the room fills up
Zoom's plan page lists the maximums, and the Meetings API says users see an error if the meeting's capacity is reached. Beyond that, the pages don't describe the experience at the cap, so plan as if the limit is firm and size the meeting to fit.
Length works the same way. On Basic, a meeting stops at 40 minutes whatever the headcount. If you run longer sessions, that's often the limit you'll hit first, long before the seat count.
Registrations versus seats
This is the part that catches event hosts out. The Zoom Meetings API documentation caps registrants at 4,999 per meeting and returns an error when capacity is reached. That means a registered crowd can be far larger than the room you can run: you could take thousands of sign-ups for a meeting that only seats 100 or 300.
Check both numbers before you promote an event. If you expect more people to show up than your meeting holds, you need a webinar, not a bigger promotion push. My guide to setting up Zoom registration covers the sign-up side in more detail.
Meeting or webinar: which fits your audience
- Up to 100 people who need to talk: a meeting on Basic or Pro, with Pro if it runs past 40 minutes.
- Up to 300 interactive participants: a meeting on Business.
- A larger audience that mostly watches: a webinar, listed at up to 500 attendees on the standard webinar platform.
- A very large broadcast: Zoom's developer docs describe the webinar feature broadcasting a meeting to up to 10,000 attendees.
If you're new to the format, my explainer on what a Zoom webinar is and how hosting one works sets out how it differs from a meeting.
Recurring meetings and scheduling caps
A few smaller limits matter if you run regular sessions. Recurring meetings and recurring webinars can have a maximum of 50 occurrences, so a weekly call needs a new series roughly once a year. The Meetings API lets you register up to 30 registrants at once with the batch registrants endpoint, which matters if you import attendee lists.
Calendly's Zoom troubleshooting page also says Zoom lets each user schedule up to 100 meetings per day across all Zoom apps. It adds that, as of Nov 2026, free Zoom accounts have a 40-minute limit and longer meetings need a higher Zoom plan.

Other video tools for smaller calls
Jitsi describes Jitsi Meet as a fully encrypted, 100% open source video conferencing solution that needs no account. Whereby's meetings product lists instant video calls and permanent room links for individuals and teams. For more options, see my list of Zoom alternatives.
My advice for sizing your next call
Work backwards from the people who'll turn up and whether they need to speak. If it's a conversation, keep it under the 100-seat meeting cap and make sure your plan covers the length. If it's a talk to a crowd, use a webinar from the start rather than squeezing into a meeting. And never let registrations run past the room you can host.
