# Pizza Calculator

> A free pizza calculator that tells you exactly how many pizzas to order for any group size, based on slices per person and pizza size. Covers standard sizes and the major chains (Domino's, Pizza Hut, Papa John's, Little Caesars, Pizza Pizza).

Key facts our content establishes:
- Standard slice counts: small pizza = 6 slices, medium (12") = 8 slices, large (14") = 10 slices by the generic cut.
- Chain large pizzas (14") are cut into 8 slices at Domino's, Pizza Hut, Papa John's, and Little Caesars (same count as a medium, just bigger slices). Papa John's X-Large (16") = 10 slices.
- Planning rule of thumb: ~3 slices per adult, ~2 per child; always round up to whole pizzas.
- Formula: total slices = (adults x adult_slices) + (children x children_slices); pizzas = ceil(total_slices / slices_per_pizza).
