Plan stable calls before meetings begin easily today. Compare quality presets, participant counts, and duration. See clearer capacity needs for teams, classrooms, and webinars.
| Scenario | Participants | Visible Tiles | Send Quality | Receive Quality | Screen Share | Duration |
|---|---|---|---|---|---|---|
| Daily team standup | 6 | 4 | 360p | 360p | 720p | 30 min |
| Training workshop | 20 | 6 | 540p | 360p | 1800p | 90 min |
| Client review session | 4 | 3 | 720p | 720p | 720p | 45 min |
1. Base attendee upload = local send video bitrate + audio bitrate.
2. Base presenter upload = attendee upload + active screen share bitrate.
3. Base per-user download = visible remote video tiles × receive video bitrate + screen share bitrate + audio bitrate.
4. Planning factor = (1 + protocol overhead) × (1 + safety headroom).
5. Planned bandwidth = base bandwidth × planning factor.
6. Meeting data in GB = bitrate × seconds ÷ 8 ÷ 1,000,000.
This design returns min, typical, and max estimates by using bitrate ranges for video tiles and screen share tiles.
Enter the number of participants and how many remote videos are visible at once. Choose send and receive video quality, then decide whether one active screen share should be included.
Set meeting duration, audio bitrate, protocol overhead, and extra planning headroom. Add your available upload, download, and latency to compare the plan against your current connection.
Press Calculate Bandwidth. The result block appears above the form, showing attendee, presenter, per-user, and whole-meeting estimates, plus a graph and downloadable CSV or PDF output.
Each visible remote tile consumes download bandwidth. Seeing four large video tiles usually needs less bandwidth than decoding nine or sixteen tiles at the same quality setting.
A presenter sends camera video and a screen share at the same time. That extra outbound stream often creates the highest upload requirement in the meeting.
They represent the lower bound, midpoint, and upper bound of the chosen bitrate range. They help you plan for steady use and heavier moments.
Yes. Raw media bitrates ignore packet overhead, congestion, and temporary spikes. Keeping both values produces a more practical planning estimate for real networks.
For most attendees, yes. A participant sends one camera stream but may receive several remote tiles and a screen share, which increases downstream demand.
Yes. Use the whole-meeting totals to estimate aggregate demand, then scale by concurrent rooms, classes, or teams sharing the same internet circuit.
Usually yes, especially for high-resolution content. Slide decks use less than fast-moving video or detailed product demos shared at larger resolutions.
Absolutely. Good bandwidth with poor latency can still cause freezes, delay, and audio problems. Review both speed and round-trip time before important calls.
