How many pizzas do you need for 25 people? The quick answer: order 9-10 large pizzas for 25 adults, or 7-8 large pizzas for a mixed group of adults and children. This guide breaks down exactly how to calculate the right amount of pizza, choose the best variety, and save money on your order.

Quick Answer: Pizza for 25 People

Pizza Quantities for 25 Guests

All Adults (moderate appetite): 9-10 large pizzas
Mixed Adults and Children: 7-8 large pizzas
Mostly Children: 6-7 large pizzas
Hungry Adults (game day, sports event): 11-13 large pizzas
Light Eaters (with other food): 7-8 large pizzas

These numbers are based on standard serving sizes: adults typically eat 2-3 slices and children eat 1-2 slices. A large pizza usually has 10 slices, so for 25 people at 3 slices each, you need 75 slices total—that's 7-8 pizzas minimum, plus a buffer for seconds and variety.

The Pizza Math: Calculating for 25 People

Step-by-Step Calculation

For 25 adults with average appetites:

25 people × 3 slices per person = 75 slices needed
75 slices ÷ 10 slices per large pizza = 7.5 pizzas
Round up + buffer = 9-10 large pizzas

Why the buffer? You never want to run out of pizza mid-party. Having 1-2 extra pizzas ensures everyone can have seconds, accommodates unexpected guests, and accounts for those with bigger appetites. Plus, leftover pizza makes a great next-day lunch!

Adjust for Your Specific Group

When to Order More

Teenagers or young adults in the group (+2-3 pizzas)
Game day or sporting event (+2 pizzas)
Pizza is the only food (+1-2 pizzas)
Party lasting 3+ hours (+1 pizza)

When to Order Less

Appetizers and sides being served (-1-2 pizzas)
Many young children in the group (-2 pizzas)
Dessert or cake being served (-1 pizza)
Short event under 2 hours (-1 pizza)
