Common questions

How many slices does the average adult eat?

The planner assumes 3 slices per adult and 2 per child. Bump the hunger level up if it's a main meal rather than a snack.

What size pizza should I use?

A large pizza is usually cut into 8 slices, which is the default. Set the slice count to match what your pizzeria actually serves.
