You can find a pizzeria in almost every city in the US and maybe the entire world. Pizza conquered the world before the internet or cell phones had their first prototypes.

Pizza is the empire on which the sun never sets. Its firm crusts, sweet yet spicy tomato sauce, and stretchy cheese are the foundation of any house party from Tokyo to London, New York to Sydney.

Everyone has their favorite kind. Many love the look and taste of a fresh pepperoni pizza, its red meat slices sprinkled over hot, baked mozzarella. Others prefer veggies: spinach, onions, mushrooms, and maybe some fresh peppers. There are even some people that put pineapple on their pizza. And they love it.

We're all different, but we are all united under the banner of pizza. There are not many things in life that beat that warm feeling of a full, fresh box of yummy pizza on your lap, and the pizza party calculator might be a tool to help you enjoy your round meal!

Pizza calculator — how to measure value for money

But what pizza should you get? Most pizza places offer more than just one size. Everybody likes to have a choice. Some want a small one to ensure they can eat everything in one sitting. On the other hand, others believe that less is more unless it's pizza.

And they order the biggest one. And eat the crust.

We've developed a pizza calculator that helps everybody make the right choice. It's straightforward — you provide the diameter and price of a small and large pizza. We calculate the actual cost of an area of those pizzas, compare them and indicate which circle is cheaper. We mainly base this on our tool called circle calc: find A.

We did our experiments (tasty experiments) — in most cases, our pizza calculator says that the larger pizza is cheaper. But life is like a box of pizza — always full of surprises (but mostly yummy ones). It's not often that you will be getting the worse deal.

Don't forget to leave a tip for your pizza! It's a good thing to share your joy with others. Our tip calculator will help you either share the bill equally or, depending on the number of eaten slices, it will also tell you how much you should tip for your delicious meal.

What made pizza so great? Pizza fun facts

5 billion pizzas are ordered every year on planet Earth. It's not hard to guess why; pizza is easy to make, full of carbs, and soul-satisfyingly delicious. 60% of those pies are sold in the U.S., which makes America the biggest pizza empire in the world.

There are 70,000 pizzerias in the U.S., which means there is one pizzeria for every 4500 people. That's even more than the number of cities in America, at least according to the Census Bureau (19,354).

According to, every second Americans eat 350 slices of pizza. Most of those slices are eaten on Super Bowl Sunday, when 58% of Americans order pizza. That's more than the turnout in the 2016 presidential election!

Pizza's wonderful story

It all started, obviously, in Italy. For many years, pizza was the basic meal for the poor citizens of Italy. What changed its status was a royal visit to Naples, the hometown of pizza.

After Italy's unification, King Umberto I and Queen Margherita visited the south of Italy in 1889. They wanted to eat something local. They visited a local pizzeria, and among the many options, they got one with tomatoes, mozzarella, and fresh basil. The legend says the royal pair liked it because this pizza's colors resembled the colors of the Italian flag.

So everyone started calling this pizza "Margherita", after the Queen. This is where it all started; pizzerias began to be opened in almost every corner of Italy and wherever Italian emigrated.

Many Neapolitans went to the U.S. In 1905, the first pizzeria was opened in New York, but it mainly attracted fellow Italians.

Pizza had to wait until after World War II, after American soldiers tasted pizza on Italian soil, to become a universally acclaimed super-food.

And the world has not looked back since.

The biggest pizza in the world

Some say there is no such thing as too big a pizza. If you don't wish to eat it now, try microwaving it in the morning. But you might have problems with microwaving those behemoths that compete for the status of the biggest pizza ever made.

Quite possibly, you'd need to have a microwave oven the size of Michigan Stadium.

In 1987 Lorenzo Amato and Louis Piancone made 10,000 square feet, the size of over two basketball courts, pizza in Havana, Florida. That pepperoni pizza was cut into over 94 thousand slices which fed over 30 thousand people.

Three years later, in Johannesburg, South Africa, a larger pizza was made from (literally) tons of flour, cheese, and tomato. It was round, not square like the one in Havana, and had a diameter of a whopping 123 feet and was, according to our pizza calculator, 11,825 sq ft big.

But in 2012, pizza went home. In Rome, Italy — the place where it all started — five men: Dovilio Nardi, Andrea Mannocchi, Marco Nardi, Matteo Nardi, and Matteo Giannotte made something even better: a 13,580 square feet of cheesy, crusty, and gluten-free awesomeness. That's right — gluten-free. Italians not only made an attempt at beating the Guinness World Record but also decided to promote a healthy diet.

It was a win for the Italians, healthy food, but most of all — it was a glorious day for pizza.

But some say that every day is great for hot, greasy, and delicious pizza. We can't argue with that. By the way, if you're a person who uses microwaves to heat your pizza, the microwave wattage converter could be helpful to see the difference in heating time for microwaves with various power.

What is the true cost of a pizza with an area of 10 in²?

Assuming that the pizza costs $25, the true cost is $2.50 per in². To calculate this, divide the price of your pizza by the area: 25/10.

How do I calculate the area of a 10-inch pizza?

When you order a 10-inch pizza, you are ordering by diameter. So to find the area of your pizza using the diameter, we use these steps:

  1. Use the formula:

    Pizza Area = π × (Diameter/2)²

  2. Substitute the values for pi and diameter:

    Pizza Area = 3.14159265359 × (10/2)²

  3. The result is 78.53 in².

That's it! You have calculated the area of your pizza.

What is the area of a 14-inch size pizza?

154 in². To calculate the area of a 14-inch size pizza, we use the formula for the area of a circle:

Pizza Area = π × (Diameter/2)²

What size is a 16-inch pizza?

A 16-inch size pizza is 16 inches across the center and has an area of 201 in². This size pizza is usually enough to feed 5-6 people.
