Pizza Size Calculator – Measure Perfect Pizza

This tool helps you determine the size of a pizza to order based on your preferences and number of servings.

Pizza Size Calculator

Use this calculator to determine the size of your pizza slices. Simply enter the diameter of your pizza in inches and the desired number of slices. Click “Calculate” to see the area of the entire pizza and the area of each slice.

How It Works

The calculator uses the formula for the area of a circle, which is π * radius2. First, it divides the diameter by 2 to get the radius. Then, it calculates the total area of the pizza and divides that by the number of slices to determine the area of each slice.

Using the Calculator

1. Enter the diameter of your pizza in inches.
2. Enter the desired number of slices.
3. Click “Calculate”.
4. The result will display the total area of the pizza and the area of each slice.


– This calculator assumes the pizza is a perfect circle, which may not always be the case.
– The result is based solely on area and does not account for crust thickness or toppings.
– It requires valid input values greater than zero for both diameter and number of slices.
