Pizza Size Calculator

The Pizza Size Calculator helps you compare different pizza sizes and determine which offers the best value for your money. By calculating the area of each pizza and dividing by the price, you can make informed decisions when ordering pizza and maximize your pizza-to-dollar ratio.

How Pizza Size Affects Value

Pizza area increases exponentially with diameter, not linearly. This means that a 16-inch pizza has significantly more area than a 12-inch pizza - about 78% more area! Understanding this relationship helps you realize why larger pizzas often offer better value per square inch.

Pizza Math Explained

  • Area Calculation: π × (diameter ÷ 2)² = pizza area in square inches
  • Value Calculation: Price ÷ Area = cost per square inch
  • Size Comparison: Lower cost per square inch = better value

Beyond Size: Other Factors to Consider

While this calculator focuses on size and price, remember that other factors affect pizza value: crust thickness, topping quality and quantity, freshness, delivery fees, and personal preferences. The "best deal" isn't always the cheapest per square inch.
