Frequently Asked Questions
What is the "3-Slice Rule" for pizza parties?
The standard catering guideline assumes an average adult will eat 3 slices of a large pizza. Hungry guests or athletes typically eat 4 to 5 slices, while kids and lighter eaters consume 1 to 2 slices.
Why order 14-inch Large pizzas instead of Mediums?
Geometry! A 14-inch Large pizza has 154 square inches of food, while a 12-inch Medium has only 113 square inches. A Large gives you 36% more pizza for usually just 15–20% higher price, making Large pizzas significantly cheaper per slice.
How should I split flavors for a diverse group?
Stick to the 40/30/15/15 ratio: 40% Pepperoni (America's favorite topping), 30% Plain Cheese (safe for kids and vegetarians), 15% Meat Lovers (Sausage/Bacon), and 15% Veggie or Specialty (Mushroom, BBQ Chicken, or Hawaiian).
