Pizza calculator for a party
Start with who is coming and how many slices they tend to eat.
How we worked this out
- Adults often eat 2 to 3 slices and children 1 to 2. Set these to your guests and the shop's cut.
- Dietary percentages are separate pizza types and must total 100% or less. Gluten-free rounds first if a small order can't fit both shares.
How the estimate works
Slices round up for the spare allowance, then pizzas round up by slices per pizza. Gluten-free pizzas round up first, then vegetarian pizzas.
Check the actual slices per pizza and confirm dietary orders with your guests.
