How much pizza for a kids' party?
Two slices per child, mostly cheese, and do not forget the parents.
Updated November 12, 2026
Slices per child, by age
- Ages 3 to 5: 1 slice.
- Ages 6 to 10: 2 slices.
- Ages 11 to 13: 2 to 3 slices.
- Teenagers: 3 to 4 slices. Count them as hungry adults.

Count the parents
The most common mistake is ordering for the children only. If parents are staying, add them as adults at 2 to 3 slices each. The calculator has separate boxes for adults and kids.
Toppings kids actually eat
Plain cheese first, pepperoni second, and very little else. For a kids' party, make two thirds of the order cheese. Order one pizza with more toppings for the adults.
Make the pizza go further
- Ask the shop to cut each pizza into 12 or 16 slices. Small hands take small pieces and waste less.
- Serve fruit, vegetables and chips alongside. With cake coming, most children stop at one or two slices.
- Serve pizza before the cake, not with it.
Allergies
Ask every parent about allergies on the invitation. Dairy, wheat and nut allergies are the common ones. Order a separate pizza for any child who needs one and keep it in its own box.
