Cooking is an art, but baking? Baking is pure science. And no baked good relies more heavily on mathematical precision than the pizza. From the surface area of the slice to the percentage of water in the dough, numbers determine deliciousness.
Planning a Party?
Stop guessing how many pizzas to order. Use the Pizza Calculator to get the exact count based on appetite and guest count.

Here is a classic math trap: One 18-inch pizza has more food than two 12-inch pizzas. "No way," you say. "18 is less than 24!"
Let's look at the math (A = πr²):
- 12-inch pizza: Radius is 6. Area = 36π ≈ 113 sq in. Two of them = 226 sq in.
- 18-inch pizza: Radius is 9. Area = 81π ≈ 254 sq in.
The 18-inch pizza is significantly larger. Always do the math before you order.
2. The Golden Ratio of Toppings
Topping distribution is key. Too much, and the structural integrity of the slice fails (the dreaded "floppy tip"). Too little, and it's just sad bread. The ideal ratio keeps toppings toward the outer edge, as the center needs to remain lighter to support its own weight when lifted.
3. Dough Hydration Percentages
If you make your own dough, you know that "hydration" is everything. This is mass of water divided by mass of flour.
- 60% Hydration: Stiff, dense, easy to handle. Good for thick crusts.
- 65-70% Hydration: The sweet spot. chewy, bubbly, improved flavor.
- 75%+ Hydration: Expert mode. Sticky, hard to handle, but produces those massive airy bubbles you see in artisan shops.
4. The Guest-to-Slice Ratio
This is where social anxiety meets mathematics. How many pizzas do you buy for a party of 10? The "Pizza Constant" varies by group:
- Kids: 2 slices per person.
- Teenagers: Infinite slices (limit by budget).
- Adults: 3 slices per person is the safe average.
