Pizza math is important. Obviously, you want to eat as many slices as possible, but you also have to take the rest of your group into consideration (Side note: This is why we advocate for ordering one pie per person).

Want to make sure you leave enough pizza slices for everyone to enjoy? Then this is the info you need to know:

There are eight slices in a pizza pie.

The standard round pizza has eight slices, allowing for a reasonable distribution of two slices per person in a group of four.

But, sometimes, there are only six slices in a pizza pie.

Large, round pizzas such as New York-style pies call for eight slices, but what about medium and personal-sized pizzas? That’s where you’ll find six slices rather than eight.

Some pizza pies have 16 slices.

Kids really love pizza, which is why, sometimes, you have to slow their roll with double-cut slices of pizza. 

Also, 1/16th slices are much easier to grip than 1/8th slices when you have tiny hands. 

Kids, don’t worry – someday, when you grow up, you’ll be able to handle a full slice. And, if you eat your vegetables, you might even be able to palm a D.C. Jumbo Slice.

Some pizza pies have no slices.

That’s right. Neapolitan pizza, traditionally, is served whole and meant to be eaten with a fork and knife.

But don’t let that stop you from enjoying a Neapolitan pie in the traditional American matter – feel free to DIY the slicing operation and create as many slices as you darn well please.
