How many pizzas for a teenage party?
A teenage party breaks the rules the younger age bands follow. Teenagers do not graze and hold out for cake, they eat, and an evening party runs straight through dinner. The count below is twelve teenagers from six until nine.
The answer
12 children aged 13 and up and 2 adults, 6:00 PM for 3 hours.
7large pizzas
54 slices at 4 per child and 3 per adult, rounded up to whole pizzas. Teenagers eat about four slices. Plan generously.

Twice the appetite of a six year old
The per person figure here is roughly four slices against two for a school age child. Using a general kids party guide for a room of fifteen year olds is the one direction where under ordering is likely, and it is the version people remember. If anything, order the larger count and expect none of it back.
This party runs through dinner, so plan a real meal.
