Pizza Sizes: Which Size Should You Order?

Takeaways describe pizza size in inches across the middle, but the amount of pizza grows much faster than the number. A few extra inches can almost double what you get, which is why one large pizza often beats two small ones.

Common pizza sizes in the UK

There is no standard size, so a “medium” in one takeaway can be a “large” in another. Always check the inches on the menu. The table shows typical names and how much pizza each size actually gives you.

Why bigger pizzas are often better value

The amount of pizza depends on the area of the circle, not the width. A 14-inch pizza has almost the same amount of pizza as two 10-inch pizzas, and a 16-inch pizza has more than five times as much as a 7-inch one. If the price of a large is less than twice the price of a medium, the large usually gives you more for your money.

Two smaller pizzas still make sense when people want different toppings or bases.

How much pizza to order

Appetites vary, but as a rough starting point:

One person
A 9 to 10-inch pizza, or a 12-inch if you are hungry or want leftovers.
Two people
One 14-inch pizza, or two 10-inch pizzas if you want different toppings.
Three or four people
Two 14-inch pizzas, or one 16-inch pizza plus a side.
Children
A 7-inch pizza is usually plenty for a younger child.

Slices

Larger pizzas are often cut into 8 slices and smaller ones into 4 or 6, but slice size changes with the pizza. Counting slices is a poor guide to how much food you are getting; the inches are what matter.

Common questions

How big is a large pizza?

Most UK takeaways call a 12 to 14-inch pizza a large, but it varies. Check the inches on the menu before you order.

Is one large pizza better than two small ones?

Often, yes. A 14-inch pizza has about 154 square inches of pizza, while two 9-inch pizzas have about 128. Compare the prices on the menu to be sure.

How many slices are in a 12-inch pizza?

A 12-inch pizza is commonly cut into 8 slices, though some places cut it into 6.
