🍕Pizza Size Calculator — Best Value
A pizza size calculator compares the area and value of different pizza sizes, revealing whether a larger pizza is genuinely better value. Because pizza area grows with the square of the radius (πr²), a 16-inch pizza contains significantly more than twice the pizza of a 10-inch.
- 1Calculate the area of each pizza: A = π × (diameter / 2)²
- 2Calculate price per square inch: Price ÷ Area
- 3The pizza with the lower price per square inch is better value
