Planning quantities for an event
Start with a realistic guest number. Not everyone invited will come, so the invitation-count planner works back from the attendance you want to how many invitations to send.
Food and drink
Per-person amounts and service-style uplifts in these tools are editable planning assumptions, not catering standards or guarantees. Set them for the menu, meal timing, guest mix, event duration and other food available; the food-weight estimates do not account for every course unless you estimate courses separately. Ice needs likewise depend on the drinks, chilling method, weather and event length.
Space and seating
Room-capacity figures apply simplified floor-area allowances to the usable dimensions you enter; they are not legal occupancy limits and do not model doors, aisles, stage space, furniture or venue rules. Standing, theatre and banquet layouts need different clearances, so use the result only as an initial comparison. Check the room-capacity estimator first, then the table and chair calculators. The venue's approved capacity and safety requirements take priority.
