Why Pizza Size is Important

Pizza size is important for 2 reasons: serving size and price.

1. Serving Size

You always want to make sure you have enough pizza. There’s nothing worse than running out of pizza, especially when you were the one in charge of ordering it. Use the chart above to determine how much pizza and in what sizes you should order for your group.

For example, if I was serving 8 adults, I would order 2 extra large, 16 inch pizzas.

Check out my full ordering guide for pizza sizes.

2. Price

You can get more pizza for a better price by ordering a larger size. 2 medium pizzas will be much more expensive than 1 large, and you’ll only be getting slightly less pizza.

If you’re trying to decide between 2 sizes, I always recommend ordering the bigger size – who doesn’t love leftover pizza?

And remember, just a pizza that is just 2 inches bigger in diameter will have much more pizza.

Now that we’ve explored the 16 inch pizza size, let’s look at some tips for choosing the right size for your next pizza night.

12 Inch Pizza Size Tips: How To Choose The Perfect Pizza Size For Your Occasion

Now that we’ve answered how big is 10 inch pizza, here’s how to pick the perfect pizza size for your next gathering by keeping these things in mind:

1. Think about how many people you’re feeding and how much they’ll each be eating. If you’re ordering pizza for yourself or for you and 1 other person, a 10 inch pizza might be perfect. If one of you is extra hungry, I would recommend ordering a 12 inch pizza.

2. Consider your budget when choosing a pizza size. 16 inch pizzas are usually more expensive than 12 inch pizzas, so if you’re on a tight budget, you may want to stick with the smaller size. That said, if you’re ordering multiple pizzas, it’s cheaper to order a larger size.

3. Think about the type of occasion you’re having. If it’s a casual get-together, a 12 inch pizza may be fine, especially if you don’t mind running out of food. But if you’re hosting a formal event or feeding a large group of people, a 16 inch pizza will give you the most bang for your buck and ensure everyone goes home with a full belly.
