How Many Slices Are in a 10-Inch Pizza? Prepare to Be Amazed!

Fun Fact: Did you know? A 10-inch pizza has a proportionally larger crust-to-center ratio, offering an ideal crispy bite in every slice!

How Many Slices Are in a 10-inch Pizza? Who does not like a pie every once in a while? This simple dish has surprisingly humble beginnings and yet has grown to become an iconic dish. However, while we indulge in the delicacy, we usually do not know what to order as there is an entire terminology for understanding the ‘pizza size’ and how to order them the best. So, Is a 10-Inch Pizza Enough for One Person? Debunking the Solo Pizza Dilemma? 

How Many Slices Are in a 10-inch Pizza?

Understanding Pizza Portions

To determine the amount of pizza per slice in a 10-inch pizza, you need to calculate its total volume. Assuming the pizza has a perfect right cylinder shape, you can obtain its volume using a specific formula and replace the known variables.

Volume = π × Radius^2 × Height 

=> Volume = π × 5^2 × ½ = 39.25 cubic inches. 

(the radius is 5 inches, and the height is ½ inch )

As a 10-inch pizza is typically sliced into eight pieces, you can take the previously mentioned number and divide it by six.

Volume per slice = 39.25 cubic inches ÷ 6 = 6.54 cubic inches.

Hence, each of the 6 slices in a 10-inch pizza will have approximately 6.54 cubic inches of crust, tomato sauce, cheese, and other toppings that you might have selected for the pizza.

Likewise, when you need to determine the weight of the 10-inch pizza, you can do so by the following:

The weight of a 10-inch pizza can differ according to the thickness of the crust, the amount and the toppings type, and the kind of cheese used. To create a pie measuring 10 inches in diameter, a pizza chef needs to use the appropriate amount of dough, which can be calculated using the formula below.

π × Radius^2 = 3.14 × 5^2 = 78.5 square inches x 0.08849 = 6.946 (7-ounces)

(Ounces per square inch = 0.08849)

The Science Behind Serving Sizes

Most pizza outlets offer various size options to make it easier for customers to personalize their pies. However, here are some factors involved in the measurement.

Confirm The Number of Slices

As mentioned, the standard slice per pizza size ratio is:

  • Six slices/8-10 inches
  • Eight slices/12 inches
  • Ten slices/12 inches
  • 12 slices/16-18 inches

Just to make sure that this size can differ according to the pizza outlet you are ordering from. Hence, talking to the chef and confirming how many slices you would prefer for each pie beforehand is recommended.

The Number of People

Got some guests coming over and have a short notice to decide what to serve? Go for pizza. Pizzas are the best idea when it comes to serving many people as it is universally appealing. It is also easily customizable, and every palate has a flavor.
However, it is important to confirm how many guests are coming over, as it is important to place an order. Otherwise, you will end up either buying more or less, and this can be quite embarrassing.


Apart from counting your guests, you must also keep their ages in mind.
For example, if you are going to entertain a group of 40 people, find out if there are any kids. Hence you will need to analyze roughly whether they would like a bite or not. These are the aspects that determine the size and the portion of the pizza you need to order.


The appetite is yet another aspect that should never be underestimated. Some of the most regular pizza appetites range from one slice to five slices. However, different people have different appetites.
There are times when you might even find yourself having different appetites at different times. Hence, it would be great if you take into account your guests’ appetites when placing a pizza order.

Is a 10-Inch Pizza Enough? Comparing to Other Options

How Big Is Each Slice of a 10-inch Pizza? What if it is not enough for all? In this case, you will need to try and understand the other pizza-size options. 

10-Inch Vs. 12-Inch pizza

If a pizza you have ordered comprises only 6 slices and can only serve 1 to 3 adults, you might want to order another box so that each adult can eat at least 3 slices.
In case you order a 12-inch pizza, on average, you will get 8 slices. Hence every individual would be able to eat at least 2 slices. However, your personal choice will also depend on your budget and appetite.
For example, if 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

Let’s say you are a group of light eaters; a 10-inch pizza from your favorite Pizza outlet might not be enough. As each box comprises only 6 slices and serves about 1 to 3 adults, you may end up wanting more.
To keep the group happy, you can order a minimum of 2 boxes of 10-inch pizzas so that everyone can enjoy 3 slices each.
Another option would be a 14-inch pizza, which is normally large at most pizza places. This way, every person will be able to enjoy 2 slices each.
According to your appetite, ordering two 10-inch boxes is perhaps the best for big eaters as it has an area of 314.16 square inches compared to a 14-inch pizza with only an area of 153.93 square inches.

Factors to Consider

Now, let us take a look at some of the main factors that affect the size of the pizza:

Crust Thickness Matters

The thickness does not directly impact the size of the pizza; however, it does effects the amount and the kind of toppings and the sauce that can be ‘baked’ into it. This, in turn, greatly affects the size of the pizza. As for the thinner crust, it cannot hold too much of the toppings; hence, the diameter of the pizza needs to be smaller accordingly. So, the next time you are in a dilemma, it is advisable to consider the top-to-crust ratio before you decide on the thickness of the crust.
Now let’s get talking about toppings. The topping options for a 10-inch pizza are innumerable and can differ according to personal preference and cultural or regional differences. Certain popular toppings are pepperoni, sausage, mushrooms, onions, peppers, olives, and extra cheese.
If you are in the mood for adventure, you can also opt for some non-traditional toppings like pineapple, jalapenos, bacon, or BBQ sauce. The main idea is to find the perfect balance of flavors and textures that tickle your palate.

The Case for One Person

A personal pizza is considered to be sufficient for an individual’s meal. The size can differ depending on who you ask. Generally, a ‘personal pizza’ is smaller than a small pizza as it is meant for one person only and is generally around 6 to 8 inches. For example, a personal pan pizza in one of the leading Pizza outlets measures only 6 inches and contains 4 slices. Hence, some people might not consider a 10-inch pizza a personal pizza because smaller sizes are available in many popular places.
If you are a light eater, a 10-inch pizza should be more than enough to fill your stomach. Because most leading Pizza houses offer 10-inch pizza that has 6 slices, you might even find yourself with a few slices left over. Now, in the case of medium to heavy eaters, a 10-inch pizza is just perfect. If you are too hungry, surely you won’t have any leftovers in this case.
While pizza is a complete meal in itself, however, there are individuals (like myself) who like to club in some other items as well. However, when combined with other side dishes, it can grow into a dining experience in itself. As pizza is usually associated with ‘casual eating,’ did you know it can also be transformed into semi-formal dining as well? Try clubbing it with some great Ceasar Salad, and any Italian-style wines like Sangiovese, Nebbiolo, Barbera, Nero d’Avola, Fiano, and Vermentino are just as good. Other siders like Mozzarella Sticks, Dough Balls, Jalapeno Poppers, and Green Beans are wonderful options too.

When One Isn't Enough

There are some of us who don’t like to share food ( like ‘Joey’ from Friends), and nothing seems to be quite ‘enough.’ Such people will find a simple 10-inch Pizza ‘small’ or not enough. For some, the regular 10-inch pizza is a ‘personal pizza,’ you might also want to order another one when too hungry. Other aspects are the crust’s thickness, the choice of toppings used, the size of the slices, and more. Hence, it is important to make sure that you check out all these options and considerations when ordering a Pizza for yourself. What’s more, there is always a Pizza for all occasions and for every person. 

How does one share and cut a Pizza into appropriate sizes: 

    • Use a sharp knife or pizza cutter: Using a dull knife or pizza cutter can cause the pizza to tear or squish, hence making it difficult to cut slices evenly. Make sure that the tool is sharp to make clean and straight cuts.
    • Let the pizza cool down: Did you know that cutting a hot pizza can cause the cheese and toppings to slide around, making it difficult to get a clean cut? So, it is advisable to wait a few minutes for the pizza to cool down before slicing.
    • Use a cutting board: Place the pizza on a cutting board to prevent damage to your countertop.
    • Cut the pizza in half: Use a knife or pizza cutter to cut the pizza in half, creating two halves.
    • Cut each half in half again: This way, you need to continue cutting the pizza in half until you have the desired number of slices. Hence for a 10-inch pizza, cutting each half into two slices will give you four equal slices.
    • Use a pizza rocker: This specialized cutting tool allows you to cut through the pizza with a rocking motion. Hence making it easier to cut slices evenly.
    • Experiment with different cutting methods: According to your personal preference, you might find that cutting the pizza into squares or rectangles instead of traditional triangular slices is a better idea.
