Food Flow Calculator
Trade fairs, festivals, and big events often face one problem: queues. We’ve built a model to show how different service setups impact throughput, production, and the visitor experience.
Why this matters
Every event organiser knows the pain of bottlenecks at mealtimes. 10,000 visitors, all hungry, all at once — the maths matters. Our Food Flow Calculator models three scenarios:
- QR-only: pre-order + in-service QR ordering
- Mixed: QR pickup + in-person ordering & payment
- Counter-only: traditional queue, order, pay
This page lets you explore the trade-offs and see instantly how many merchants, lanes, and staff are needed to avoid queues.
The model behind the numbers
- Visitors: Default 10,000 visitors to be served in a 3-hour window
- Service slots: Demand smoothed into 5-minute slots (adjustable)
- Production rates: Merchants can prepare 170–200 meals/hour (adjustable)
- Pickup time: 12 seconds per QR handover (~300/h per lane)
- Cashier time: 55 seconds per order (~70/h per lane)
- Queues form when either production or service lanes can’t keep up with demand/hour
These assumptions are editable — change the values in the calculator and see how the outputs shift.

Adjust the inputs below to see how different service setups perform. Tip: Try reducing merchants to 10, or changing the QR share to 30%. You’ll see how quickly bottlenecks form.
