How many pizzas for 20 people?
Order about 8 large pizzas for 20 adults. At 3 slices each, 20 people eat 60 slices, and 60 ÷ 8 slices per pizza = 7.5, so round up to 8. For a light crowd with other food around, 5 pizzas (2 slices each) is enough.
| Guests (adults) | Light eaters (2 slices) | Normal (3 slices) | Hungry (4 slices) |
|---|---|---|---|
| 10 | 3 pizzas | 4 pizzas | 5 pizzas |
| 15 | 4 pizzas | 6 pizzas | 8 pizzas |
| 20 | 5 pizzas | 8 pizzas | 10 pizzas |

| 30 | 8 pizzas | 12 pizzas | 15 pizzas |

How many slices of pizza per person?
Pizza Hut's own planning tip is 2 to 3 slices per adult and 1 to 2 per child. The calculator uses 3 slices for a normal adult appetite and 2 for kids, then rounds up to whole pizzas so you don't run short.
Example: a kids' birthday with 12 kids and 6 parents
- Kids: 12 × 2 slices = 24 slices
- Parents: 6 × 3 slices = 18 slices
- Total: 42 slices ÷ 8 = 5.25, so order 6 large pizzas
Tips for ordering pizza for a group
- Mix it up: for every three pizzas, make one plain cheese. Kids and picky eaters go for it first.
- Order one extra for teens, sports teams or a party that runs through dinner.
- Ask the pizza place how many slices their large is cut into. Some cut 10 or 12 thinner slices.
- Have salad, fruit or chips on the side and you can drop to 2 slices per adult.
