About this calculator
The Pizza Calculator (comparison) helps you decide which pizza offers the best value for money. Simply enter the diameter and price of two pizzas, and the tool calculates the price per square centimeter for each. The pizza with the lower price per cm² is the most cost-effective.
The calculation is straightforward: divide the price by the area of the pizza, which is obtained using the formula π × (diameter/2)². This allows you to fairly compare pizzas of different sizes, as the total price does not reflect the true value per unit area.
Use this calculator whenever you are at a pizzeria or ordering online and want to maximize your money. For example, a large pizza may seem more expensive but have a lower cost per cm² than a medium one. Perfect for parties, events, or group dinners.
Caution: also consider crust thickness and ingredient quantity, which are not taken into account. The calculation is purely area-based. Prefer stuffed crust or extra toppings? The price per cm² may not reflect overall satisfaction.
Frequently asked questions
How do I compare more than two pizzas?
You can use the calculator multiple times, comparing two at a time, or manually calculate the price per cm² for each and compare the results.
Does the calculator consider square or rectangular pizzas?
No, it is designed only for round pizzas. For other shapes, you would need to calculate the area differently.
What does price per cm² mean?
It is the cost of each square centimeter of pizza. The lower this value, the more pizza you get for your money.
Can I use the calculator for very different pizza sizes?
Yes, it works for any diameter. Just keep in mind that very large pizzas may have thinner crusts, which is not considered.
Does the calculator account for discounts or promotions?
No. You should enter the final price you will pay, with any discounts already applied.
