For 20 adults at a full meal, plan about 30 burger patties or 6 large pizzas, plus 2 to 3 side dishes, drinks, dessert and supplies. Use the calculator above for exact package counts.
Plan 2 to 3 slices per adult. A large pizza has 8 slices, so 20 adults need about 6 large pizzas, or 5 when you are serving filling sides.
A practical estimate is one main serving per adult, about a third of a pound of sides per person, two drinks per person for every two hours, and one dessert per guest.
For 100 adults at a full meal, plan about 100 to 150 pounds of total food, with multiple mains, 4 to 6 side dishes, drinks, dessert and supplies. The calculator converts that into exact package counts.
For 50 adults at a four-hour party, plan about 250 total drinks, or about 5 per adult. Split that across soda, water and any beer or wine.
