How much bigger is an 18-inch vs 16-inch pizza?

A 18-inch pizza is approximately 27% larger than a 16-inch pizza in terms of area.

The size of a pizza is determined by its diameter, which is the distance across the center of the pizza. An 18-inch pizza is 2 inches larger in diameter than a 16-inch pizza. However, the difference in size between the two pizzas is not just four inches, but rather the area of the 18-inch pizza is significantly larger than the area of the 16-inch pizza.

How to calculate the area of a circle

To calculate the area of a circle (and thus the area of a pizza), you use the formula A = Ο€r^2, where A is the area, Ο€ is pi (approximately 3.14), and r is the radius of the circle (which is half the diameter).

But you don’t have to do all these calculations with a pen and pencil β€” use our calculator.
