Meeting room bandwidth calculator
How much bandwidth do ten Zoom Rooms need if they're all in a call at once? Pick the platform, enter the rooms, add headroom.

Platforms update these figures. Check the current published requirements, linked below, before committing to a circuit size. The Webex and Google Meet rows were added on 2026-11-15.
How it works
Multiply the per-room figure by the number of rooms that could be in calls at once, then add headroom for screen sharing, software updates and everything else on the network. Size the circuit for the busy hour, not the average.
Field notes
- Upload is usually the limit. Many business circuits are asymmetric, and a room sends its camera feed up while it receives the others down.
- Platforms adapt. Zoom and Teams scale video down when bandwidth is short, so a tight circuit means soft video before it means dropped calls.
- Teams Rooms have no bandwidth cap by default. Microsoft suggests a 10 Mbps policy per room if you set one, and says a room typically uses only 3–4 Mbps of it.
- Prioritize the media traffic. Set up QoS on the LAN so meeting audio is never stuck behind a file download.
- Check the actual calls. Both platforms show per-call network statistics in their admin centers, which beat any estimate.
