A Short Answer to the Topic

How big is a 10-inch pizza?

If you don’t have a ruler, you can use your thumb to measure it. Most people’s thumbs are about an inch long, therefore, a 10-inch pizza is around 10 thumbs long.

A 10-inch pizza has an area of 78.5 square inches [1], which is the amount of pizza available for eating.

How Many Slices Are in a 10-Inch Pizza?

Ten-inch pizzas are popular since they aren’t too big or small. If you’re wondering if a 10-inch pizza is enough to share with friends, then you’ll want to know how many slices there are.

Pizzas come in different sizes and shapes, but generally, 10-inch pizzas have between 6 and 8 slices. This may vary depending on the pizza store, the size of their slices, and the pizza crust.

When entertaining a small group or hosting an intimate supper, a 10-inch pizza could be the right choice. But how many people does it actually serve?

A pizza’s servings can depend on a variety of factors, one of which is the appetite of the diners.

At Domino’s and Papa John’s, a 10-inch pizza is considered a small-sized pizza with 6 slices and is known to serve about 1 to 3 people.

Therefore, it’s the perfect size for a family of three or a date for two, but it’s also good enough to eat on your own if you have a big appetite.

On the other hand, if you and your companions have a large appetite, a 10-inch pizza might only be enough for two people or one person.

10-inch Pizza Calories

At Papa John’s, a slice of their original crust cheese pizza is equivalent to 180 calories but an epic stuffed crust cheese pizza slice is equivalent to 360 calories.

This means that if you eat the whole thing, you’ll consume 1,080 calories for the original crust and a total of 2,160 calories if you go with the epic stuffed crust pizza.

One whole 10-inch pizza comes to approximately 1,000 to 1,500 calories with about 250 calories per slice.

The number of calories will depend on the kind of pizza you order, its toppings, and its crust.

If you want to be sure, check with your local pizzeria though you can use Papa John’s nutritional data as a starting point.

In case you were wondering, the daily calorie intake for men and women is 1,600-2,400 and 2,000-3,000 calories [3], respectively.

However, this depends on a variety of factors such as your age, height, metabolism, and lifestyle.

FAQs About 10-inch Pizza

Now that you have an idea of how big a 10-inch pizza is, let’s explore some interesting facts about this popular food item.

What is the circumference of a 10-inch pizza?

While pizzas can come in different shapes, let’s assume this is your classic, round pizza. The circumference of any circle, pizza included, is calculated by the formula C = πd.

First, get the pizza’s diameter. Diameter [4] is the distance between two circle edges. It can be visualized as a straight line passing through the circle’s center. The symbol “d” is used to represent it.

If your pizza is 10 inches then it has a diameter of 10 inches.

We know that the value of pi (π) is approximately 3.14159. Therefore, your calculation should look like this:

  • C= π*d
  • C=3.14159*10
  • C=31.4159

The circumference of your pizza is 31.42 inches.

How many slices are in a 10-inch papa john’s pizza?

A Papa John’s 10-inch pizza is considered a small pizza with 6 slices.

Approximately 250 grams of flour are used to make pizza dough for a classic 10-inch pizza. This amount may vary depending on the pizzeria and the thickness of the crust.

How many carbs are in a 10-inch cauliflower pizza crust?

Cauliflower is a low-carb vegetable that is often used as a substitute for carb-heavy food like rice and bread.

Cauliflower has similar properties to wheat flour so it can also be used to make pasta, rice, and even pizza crust [5].

If you’re looking to cut down on carbs without sacrificing taste or texture, cauliflower is a great option.

The number of carbohydrates in a cauliflower pizza crust differs depending on the pizzeria and the ingredients they use.

According to Consumer Reports, a single slice could have anywhere from 2 to 29 grams of carbohydrates [6].

They discovered that Cali’flour Foods had only 6 grams of carbs while Realgood Pizza Co had 21 grams.

Is a 10-inch pizza enough for one person?

If you’re a light eater, a 10-inch pizza should be more than enough to satisfy your hunger.

Considering that Papa John’s 10-inch pizza has 6 slices, you might even find yourself with a few slices left over.

For medium to heavy eaters, a 10-inch pizza is just enough. If you’re really hungry, we’re sure you won’t have any leftovers.

What size is a personal pizza?

A personal pizza is supposed to be good for 1 person’s meal. The size can vary depending on who you ask.

This size is smaller than a small pizza because it’s for 1 person and is often around 6 to 8 inches.

For example, a personal pan pizza is the smallest size at Pizza Hut, measuring only 6 inches and containing 4 slices.

Some people may not consider a 10-inch pizza a personal pizza because there are smaller sizes like the one from Pizza Hut.

However, restaurants with bigger servings and people with larger appetites may find that it’s sufficient to be categorized as a personal pizza.

How many pizzas do I need for 4 adults?

10-Inch vs 12-Inch Pizza

If a Papa John’s 10-inch pizza has only 6 slices and can only serve 1 to 3 adults, you’ll want to order another box so that each adult can get at least 3 slices.

However, if you order a 12-inch pizza at Papa John’s, you’ll get 8 slices, meaning each person would be able to eat 2 slices.

Your personal choice will depend on your budget and appetite.

Let’s say you order a pepperoni pizza. A 12-inch pie is considered a  medium-sized pizza and costs about $12.99 while ordering 2 boxes of 10-inch pizzas will cost $21.98 at $10.99 each.

10-Inch vs 14-Inch Pizza

Even if you’re a group of light eaters, a single 10-inch pizza from Papa John’s might not be enough. Since each box contains only 6 slices and serves about 1 to 3 adults, you may end up hungry.

To keep the group satisfied, order at least 2 boxes of 10-inch pizzas so each person can get 3 slices.

Another option would be to go for a 14-inch pizza which is considered a large pizza at Papa John’s. This would mean each person will get 2 slices.

Depending on your appetite, 2 10-inch boxes might be best for big eaters since it has an area of 314.16 square inches compared to a 14-inch pizza that only has an area of 153.93 square inches.
