For 15 kids, you'll likely need 4 to 6 large pizzas, assuming each child eats 2-3 slices, with 6 pizzas being a safer bet for hungry eaters or if adults are also eating; consider getting more plain cheese as it's often popular and can be cut into smaller slices.
Following the same rule that an average adult will eat around three slices, a large pizza will feed around two adults or four children. An extra-large pizza would feed around three adults and five children. It's recommended to order commonly loved toppings in larger sizes.
For 20 adults you should order 8 large pizzas. This may seem like an arbitrary number, but there's actually a pizza ordering formula that can help you figure out the proper amount to order for any size group. When serving adults at a regular mealtime, go by what is known as the 3/8 pizza rule.
For a small group: One large pizza (8 slices) can comfortably feed 3-4 people, assuming everyone eats 2 slices each. For a larger gathering: Two or three large pizzas can cover a party of 6-10 people, giving everyone a couple of slices and maybe some leftovers.
The "3/8 pizza rule" is a guideline for estimating how many pizzas to order for a group, suggesting you budget three slices per person, assuming a standard large pizza has eight slices, so you order approximately 3/8 of a pizza for each guest. To use it, multiply the number of attendees by 3/8 (e.g., 10 guests need about 3-4 pizzas), though adjusting for big eaters, kids, or other food is always wise.
The concept of Amazon's two-pizza teams is straightforward: no team should be big enough that it would take more than two pizzas to feed them.
Even elementary school, 20 kids eating 2 slices each would be 5 pies, and there would be some not eating 2, and teachers probably limiting to 2.
Count how many people you're serving, decide how many slices each person is likely to eat, then divide the total slices by the number of slices per pizza. As a baseline, use 2–3 slices per adult and 1–2 per child, then round up to whole pizzas.
Usually, the cost of a large pizza is cheaper than the total cost of buying multiple smaller pizzas. For example, if a large pizza costs $15 and 2 small pizzas cost $10 each, the total cost of buying the two small pizzas would be $20. Therefore, buying a large pizza is cheaper, saving you $5 in the process.
I always estimated half a pizza per person and it usually worked out well. Also, always get more plain cheese pizza than you think you need. It will go first. Even the kids who can eat pepperoni and or sausage will eat some plain cheese too.
Here's a rundown of how each method works. One of the most effective ways to keep pizza warm is to wrap each slice or the entire pizza in aluminum foil, which acts to prevent heat from escaping. Once your pizza is wrapped, put it in the oven at around 200 degrees Fahrenheit and heat it for 15 minutes.
Here's how to know the number of slices in a large pizza: How many slices in a large pizza with Hand—Tossed Crust: 8 slices. Each abundant slice offers a perfect balance of pizza toppings atop our hand—tossed, garlic—seasoned crust. Feeds 3—5 people.
To calculate the area of two medium 12-inch pizzas:
Then, 6² is 36. 36 x π is 113-inch², multiplied by two for a total of 226-inch² of pizza. There's no denying the numbers! The math proves that two 12-inch medium pizzas have a larger overall surface area than one 14-inch large pie.
What Are the Most Popular Toppings to Order on Pizza?
25 guests → 12–15 pizzas. 50 guests → 25-30 pizzas. 100 guests → 50–65 pizzas. 250 guests → 125–160 pizzas.
The good news is that there's a magical equation for figuring out exactly how many pizzas you'll need: For kids ages five and below, you should order one slice per child. For kids ages 5 and up, you should order 2 extra slices for every 6 kids. If you plan on feeding the parents, you should order 1.8 times more pizza.
Anything salty, tangy, crispy, or fresh—like olives, pickled veggies, salads, or cheesy bread. What food pairs well with pizza? Appetizers (bruschetta, mozzarella sticks), salads, wings, and antipasto platters pair beautifully.
A solid fallback is "The ⅜ Rule." Anticipate three slices of pizza per person and eight slices per pie. To calculate, simply multiply your crowd size by ⅜ (i.e. 20 x ⅜). Following the ⅜ rule, you would need 60 slices to feed 20 people, which comes out to eight large pies.
You Can Take Pizza Anywhere
During parties, people like to lounge or move around. With this food, your guests can enjoy a slice while sitting, standing, or even walking! Table seating is not required!
The rule I've always heard is a slice and a half per person. So you'd probably be looking at 40ish slices, which you could figure out based on the pizza shop's slices per sizes how many of a size you'd need.
One simple rule for maximizing team effectiveness. Former Amazon CEO Jeff Bezos has this rule: no team meeting should be so large that two pizzas can't feed the whole group. This is, of course, a shorthand method for ensuring that, as is often the case with big groups, no one's ideas get drowned out.
Bezos is said to have a rule about decision making, and he calls it the 70% Rule. It works like this: Whatever you're trying to figure out, you should make your decision when you have 70% of the information you need in order to come to a conclusion.
Yes, the 30-minute pizza rule was a real, famous marketing guarantee, primarily by Domino's in the 1980s and early 90s, but it was discontinued in the U.S. due to lawsuits and safety concerns from drivers rushing, though similar (but often conditional) offers still exist in other countries like India or Australia.
