Count slices, then pizzas
Estimate slices by guest group and appetite, include a small buffer, then divide by slices per pizza and round up.
Adjust for the menu
Pizza served with substantial sides usually needs fewer slices than pizza as the only meal. Very large or very small slices also change the result.
Plan variety without over-ordering
Use known dietary requirements first, then split the remaining order across broadly popular choices. Keep allergens and cross-contact in mind.
Practical checklist
- Confirm actual slices per pizza with the supplier.
- Schedule delivery close to serving time.
