What Is An 18-Inch Pizza?

How big is an 18-inch pizza?

An 18-inch pizza can be described as a large pizza. If the restaurant you are ordering from does not provide measurements for their pizzas, you can assume that an 18-inch pizza has a dimension of approximately 18 inches across. In centimeters, this is 45.72 cm in diameter (the approximate radius of an 18-inch pizza).

This size is perfect for a large party of friends or family, as it can easily be cut into 6 slices per person. With the right toppings and fresh ingredients, this size pizza can comfortably feed 8-10 people.

How Many Slices Are There In An 18-Inch Pizza?

An 18-inch pizza will be cut into 8 equal slices, each with a diameter of approximately 4.7 inches (11.94 cm). This means that 6 people can comfortably eat this size pizza with little left over for seconds and thirds. If you order the thin crust option, the same amount of pizza can be cut into 10-12 slices.

Many American-style pizzas come with 12 slices cut into 4 even quarters, or 4 pieces per person. If you are ordering from a different style of pizza, such as Neapolitan or Roman style, then it is best to ask your server for their preferred cutting guidelines in order to get the most out of your 18-inch pizza. If you are traveling to other countries, such as Italy, the 18-inch size will be referred to as a ‘gran pizza.’

How Many Calories In An 18-Inch Pizza?

The amount of calories in an 18-inch pizza slice will vary depending on the toppings added. A standard cheese pizza with a thin crust contains approximately 220 calories per slice, and a regular crust contains around 300 calories.

Adding high-calorie toppings such as pepperoni and sausage will increase the calorie count, so it’s best to check with your server for any dietary restrictions before ordering. If you are looking for something lighter – try adding some vegetables instead!

How Many People Does 18-Inch Pizza Feed?

An 18-inch pizza is perfect for feeding a large family or group of friends. Depending on the toppings, it should quickly satisfy 8-10 people with enough left over for seconds and thirds. This size is also ideal for parties where you are serving other side dishes such as pasta, salads, and bread.

If you are looking to reduce costs when hosting a gathering, an 18-inch pizza can be split into two or three different flavors in order to provide variety while still keeping portions manageable.

How To Slice An 18-Inch Pizza Evenly?

The key to slicing an 18-inch pizza evenly is first to divide the pizza into four even quadrants. You can use a ruler or other measuring device (or eyeball it!) to draw similar lines across the pizza from edge to edge.

Once you have these lines marked out, use a sharp knife or pizza cutter to slice along each of these lines. You should end up with 8 even slices with 4 pieces per person. If you are after smaller portions or want more variety in your pizzas – divide the sections into two or three smaller slices for each quadrant.

If you purchase the pizza at the restaurant, it is likely they will have their own way of slicing the pizza in order to ensure everyone can get a share. For instance, in some places, the pizza will be cut into 4 pieces per person – to make it easier for guests to share.

How Much Sauce Do You Need For The 18-Inch Pizza Size?

To get the most out of your 18-inch pizza, it is crucial to use the right amount of sauce. Depending on your preference for thick or thin crust, you should aim for about 1/2 cup (120ml) of tomato sauce per pizza.

There are a variety choices of pizza sauces, ranging from traditional marinara sauce to pesto. Using the right flavor combination will give your pizza a unique taste that everyone can enjoy. You can also add garlic and herbs such as oregano, basil, and thyme, along with other toppings like cheese, to create your unique flavor combination. For example, adding some extra virgin olive oil and a handful of fresh basil leaves will go a long way toward creating a delicious pizza!

Should You Need To Make An 18-Inch Pizza At Home Or Purchase?

Whether you decide to make your 18-inch pizza at home or purchase one from a restaurant, it is important to consider the size before making any decisions. Homemade pizzas can be time-consuming, as you must prepare and cook the dough beforehand. However, if you have the right ingredients and are feeling adventurous, why not give it a go?

If you decide to make your own 18-inch pizza, you’ll need to start making the dough. 

Step 1: Prepare the dough. This can be done by combining self-rising flour, warm water and a teaspoon of sugar in a large bowl until it forms a soft dough. 

Step 2: Knead the dough on a floured work surface for at least 15 minutes until it is soft, elastic, and no longer sticky. You should avoid adding too much flour, which will make the pizza crust dense.

Step 3: Place the dough ball on an oiled sheet pan and roll it out into a circle shape, pressing from the center outward. Use your fingers to spread the dough until it is 18 inches in diameter. You should use a rolling pin to help make sure the dough is evenly spread.

Step 4: Top the pizza with your favorite toppings, such as tomato sauce, mozzarella cheese, and pepperoni or sausage slices. You can also add vegetables and herbs for a more flavorful pizza.

Step 5: Place the pizza in a preheated oven at 375 degrees Fahrenheit and bake it for around 25 minutes or until the dough is cooked and the cheese is golden brown. If you’d like to have crispier crust, you can cook the pizza for a few more minutes.

Step 6: Let the pizza cool off before slicing and serving it. Enjoy your homemade 18-inch pizza with friends or family!

Note: You can serve the pizza with dipping sauces such as ranch, garlic butter or honey mustard. To make the crust extra crispy and flavorful, brush it with olive oil before adding toppings. You can also sprinkle grated Parmesan cheese on top for extra flavor. 

5 Tips For Getting A Delicious 18-Inch Pizza?

To get a delicious 18-inch pizza at home, you must ensure you have the right ingredients. Here are 5 tips to help make your pizza night a success:

1. Start with good quality dough – you can make your own or purchase pre-made dough from the store. Make sure it is appropriately kneaded and not too dry before stretching it out onto the pan.

2. Use enough sauce – 1/2 cup (120ml) of tomato sauce should do for an 18-inch pizza. You can add in other flavors, such as garlic, herbs, and spices, for a unique flavor combination.

3. Stick to fewer toppings – less is more when it comes to achieving that perfect balance of flavors on your pizza! Too many toppings can make the pizza soggy and heavy.

4. Preheat your baking tray – this will help ensure the bottom of the pizza is cooked evenly without burning it. Use a preheated oven at around 400 degrees Fahrenheit (200 degrees Celsius).

5. Let it rest – allowing the pizza to cool down before slicing and serving helps to hold all of those delicious flavors in place!

If you purchase the pizza from the restaurant, the tips are slightly different. You’ll need to make sure the pizza is cut into even slices and use the right amount of sauce. You also want to choose a flavor combination that everyone can enjoy – as it will be shared among your guests.
