📐 Why This Amount Works
1
Estimate actual eaters
25 guests × 95% eating rate At small events, about 95% of guests will eat full servings. 24 eaters
2
Calculate servings (as main dish)
24 eaters × 3 pizzas per person As a main dish, plan for 3 pizzas per person. 72 base servings
3
Apply birthday party modifier
× 1.3 (+30% for pizza) Birthday Partys typically consume 30% more pizza than average. 93 pizzas needed
4
Convert to pizzas
93 pizzas ÷ 8 per pizza Each pizza provides 8 pizzas. 11.6 pizzas (raw)
5
Add 15% buffer & round up
11.6 × 1.15 = 13.3, rounded up Always round up and add a buffer. Running out of food is worse than having leftovers! 14 pizzas
