Planning a pizza party for a large group can seem like a daunting task. How much pizza should you order? What if you don’t order enough and guests go hungry? On the other hand, you don’t want to spend too much and end up with a ton of wasted, uneaten pizza. Properly estimating pizza quantities for group events is crucial to ensure everyone gets enough to eat while minimizing excess waste.
Follow this guide to learn a simple formula for calculating pizza needs for parties of any size. We’ll walk through adjustments based on age, provide quick reference charts, and cover key considerations from dietary restrictions to budgeting. With some advanced planning, you can feel confident you’ll have the right amount of delicious pizza on hand to satisfy your guests. Let’s get started!
Estimating Pizza Quantities: The Formula
When determining how much pizza to buy, begin by estimating the number of people attending. Next, decide on the size of pizza you’ll provide – common options are small (8″), medium (10-12″), and large (14-16″).
Here is a simple formula for calculating pizza needs:
- Large pizzas: Order 2-3 slices per person
- Medium pizzas: Order 3-4 slices per person
- Small pizzas: Order 4-5 slices per person
For example, to feed 30 people, you would need approximately 12 pizzas. This calculation is based on the average number of slices each person consumes and factors like pizza size, crust type, and toppings
Always round up and add 1-2 extra pizzas to be safe. It’s better to have a little excess than run out of food at a party.
Adjusting Estimates for Adults and Children
When your party includes both adults and children, you’ll need to adjust pizza quantities accordingly. On average:
- Adults eat 2-4 slices per person
- Teens eat 2-3 slices per person
- Kids eat 1-2 slices per person
For a mixed group, make estimates by age bracket. For example, if you have:
- 20 adults
- 5 teens
- 5 kids
You would estimate:
- Adults: 20 people x 3 slices = 60 slices
- Teens: 5 people x 2 slices = 10 slices
- Kids: 5 people x 1 slice = 5 slices
Total slices needed: 60 + 10 + 5 = 75 slices
Buy enough pizzas so you have 75-80+ slices to comfortably feed the entire group.
Quick Reference: Pizza Slices Needed for Group Sizes
Use this handy chart to quickly estimate pizza needs for parties of different sizes. The estimates are based on medium pizzas with 8 slices each.
Number of People | Slices Needed | Pizzas to Order |
10 people | 30 slices | 4 pizzas |
15 people | 45 slices | 6 pizzas |
20 people | 60 slices | 8 pizzas |
25 people | 75 slices | 10 pizzas |
30 people | 90 slices | 12 pizzas |
40 people | 120 slices | 16 pizzas |
50 people | 150 slices | 20 pizzas |
Ordering Tips for Large Groups
Planning pizza for a very large gathering? Here are some tips:
- Order from a restaurant or pizzeria that offers large, extra-large, or party size pizzas. Each oversized pizza yields more slices.
- Choose a mix of smaller personal pizzas in addition to large ones to add variety.
- For giant parties (75+ people), consider ordering sheet pizzas that are cut into many uniform squares or rectangles.
- Have guests RSVP with their pizza preferences so you can order enough of each type.
- Set up buffet lines to efficiently serve crowds if needed.
Nutritional & Dietary Considerations
These days, many folks follow special diets or have food preferences. Be sure to have options for:
- Vegetarians: Order cheese, veggie lover’s or other meatless pizzas.
- Vegans: Select pizzerias that offer vegan cheese or dairy-free options.
- Gluten-free: Verify gluten-free crusts or pizzas are available.
- Common allergies: Ask about nut-free, dairy-free, etc. choices.
- Low-sodium or low-fat: Request light sodium or reduced-fat ingredients.
Having inclusive pizza selections will make your party welcoming for all.
Budgeting: How Much Does Pizza Cost?
Pizza is relatively budget-friendly, but costs add up quickly for large groups. Some typical price ranges:
- Small cheese pizza: $5 – $12
- Medium 1-topping pizza: $10 – $15
- Large specialty pizza: $15 – $22
- Party-size sheet pizza: $25 – $40
For a party of 30, ordering 15 medium 2-topping pizzas at $12 each would cost around $180 total.
Here are tips to save money on your pizza order:
- Choose take-out instead of delivery to avoid fees.
- Look for coupons and special deals.
- Opt for two or three topping types instead of specialty pizzas.
- Buy store-bought dough and make your own pizzas at home.
Homemade vs. Ordered Pizza for Parties
Making pizza at home takes more effort, but offers a few advantages:
- Customize ingredients to suit your group’s tastes
- Save money by buying supplies at the grocery store
- Involve guests in a fun activity of pizza-making
Ordering pizzas is convenient and practical for large parties:
- No work of prepping dough, sauce and toppings
- Can accommodate dietary needs more easily
- Guaranteed consistently delicious results
Weigh the time commitment before deciding to make homemade pizzas for more than 10-15 people. Pizza delivery is easiest for very large groups.
Choosing Toppings and Pizza Sizes
When ordering, select:
- A mix of meat and veggie toppings to satisfy preferences
- Small, medium, and large sizes to cater to different appetites
- Simple traditional toppings for crowd-pleasing flavors
- A few fun novelty or gourmet pizzas to add interest
Try these winning topping combinations:
- Pepperoni, sausage, mushrooms, onions, green peppers
- Four cheese, spinach, and artichoke
- Hawaiian style with ham and pineapple
- BBQ chicken with red onion and cilantro
Additional Tips for Planning a Pizza Party
Beyond the main course, consider these touches:
- Drinks: Soda, juice boxes for kids, beer or wine for adults
- Sides: Garden salad, breadsticks, chicken wings
- Dessert: Cookies, brownies, or an ice cream bar
- Tableware: Plates, napkins, cups, and utensils
- Activities: Lawn games, music, photo booth, trivia or karaoke
Sustainability and Food Safety Tips
When ordering pizza for a crowd:
- Request recyclable boxes and minimal plasticware.
- Use real reusable plates, cups, and utensils if possible.
- Refrigerate leftover pizza within 2 hours and eat within 3-4 days.
- Discard pizza left out for more than 2 hours at room temperature.
Being eco-conscious reduces waste so everyone wins!
