What You Need to Know
Twilio Programmable Video Rooms are not designed to support more than 50 participants in a single room. The per-room participant limit is a hard cap, regardless of your account’s overall concurrency quota.
- Per-Room Limit: Each Programmable Video Room supports up to 50 participants.
- Concurrency Quota: This refers to the total number of participants your account can have across all rooms at the same time, not the number of participants in a single room.
Recommended Solution for Large Webinars
For webinars or events with hundreds or thousands of viewers, consider a hybrid approach:
-
Small Interactive Room for Presenters:
Use a Twilio Video Room for presenters, panelists, or a small group who need to interact in real time. -
Broadcast to a Larger Audience:
Stream the video and audio from the presenters’ room to a larger audience using a broadcast solution such as RTMP or HLS. This allows you to reach hundreds or thousands of viewers with minimal delay, while keeping the interactive group small and manageable.-
Example Workflow:
- Presenters join a Twilio Video Room (up to 50 participants).
- The session is streamed out to a broadcast platform (e.g., YouTube Live, Vimeo, or a custom HLS/RTMP endpoint).
- Attendees watch the broadcast stream, which can scale to thousands of viewers.

Frequently Asked Questions
Can I increase the per-room participant limit by requesting a higher concurrency quota?
No, the per-room participant limit is fixed. The concurrency quota only affects the total number of participants across all rooms in your account.
What if I need interactive features for all 50+ attendees?
Twilio Programmable Video is not designed for fully interactive sessions at this scale. For large interactive events, consider specialized webinar or virtual event platforms.
