Frequently Asked Questions About Pizza

How many slices of pizza per person?

Adults typically eat 2-4 slices, with 3 being the average. Children usually eat 1-2 slices. The 3/8 rule (3 slices per person, 8 slices per pizza) is the industry standard for party planning.

Should I order more pizza for hungry guests?

Yes! If your guests are coming from activities (sports, hiking) or if pizza is the main meal, add 20-25% more. It's always better to have leftovers than hungry guests.

How do I keep pizza warm for a party?

Keep pizzas in a 200°F (93°C) oven. Stack boxes and rotate every 15-20 minutes. For best results, remove pizzas from boxes and place on baking sheets.

What's the best pizza topping ratio for a party?

A safe ratio is 40% cheese/plain, 30% pepperoni or meat lovers, 20% supreme/veggie, and 10% specialty. Adjust based on your crowd's preferences.
