How to read pizza sizes
A pizza's size is its diameter: the distance straight across the middle, crust to crust. The number on the menu tells you less than you would think, because what you eat is area, and area grows much faster than diameter.
Add two inches to a 12-inch pizza and you get a 14-inch with 36% more pizza. Add two more and the 16-inch has 78% more than the 12. That is why the largest size on a menu is usually the cheapest per bite.
Size names are not standard
There is no rule for what "medium" or "large" means. One chain's large is 14 inches and another's is 16. When you compare prices between shops, compare the inches. The size comparison tool works out the price per square inch for you.
Planning an order
Once you know the size, the party calculator tells you how many to order for your group.
