Pizza Calculator: How Many Pizzas
This pizza calculator answers three questions in one place. First, how many pizzas to order for a party, based on guests, slices per person and the size you pick. Second, how much dough, flour, water, salt and yeast to make for homemade pizza at the hydration you like. Third, which pizza size is the better deal, by comparing price per square inch, because a bigger pizza often has far more area than it seems. It uses US sizes in inches and works in ounces and grams. Choose a mode, fill in the boxes and read the answer.

How it is calculated
Slices needed are guests × slices per person plus the extra for seconds. Pizza area is ฯ × diameter² ÷ 4. Dough ball weight is the area times 1.9, 2.4 or 3.2 grams per square inch for thin, medium or thick crust, and the recipe is split using baker's percentages with water at your hydration, 2.5% salt, 0.3% yeast and 2% oil.

Frequently asked questions
How many pizzas do I need for 10 people?
Plan for about 3 slices per person. For 10 adults that is 30 slices, or about 4 large 14 inch pizzas of 8 slices each, plus a little extra.
How much bigger is a 16 inch pizza than a 12 inch?
A 16 inch pizza has about 201 square inches, while a 12 inch has about 113. The 16 inch has 78% more pizza for a one-third increase in diameter.
What hydration should pizza dough have?
Most home pizza dough uses 60% to 65% water by flour weight. Higher hydration makes a lighter, more open crumb but is stickier to handle.
How much dough do I need for a 12 inch pizza?
About 250 to 280 grams, or 9 to 10 ounces, for a medium crust. Thin crust uses less and thick crust more.
How do I compare pizza prices?
Divide the price by the area in square inches, which is 3.1416 times the radius squared. The lower the price per square inch, the better the value.
