📐 Why This Amount Works

Estimate actual eaters

100 guests × 85% eating rate

At large events, about 85% of guests will eat full servings. 85 eaters

Calculate servings (as main dish)

85 eaters × 3 pizzas per person

As a main dish, plan for 3 pizzas per person. 255 base servings

Apply birthday party modifier

× 1.3 (+30% for pizza)

Birthday Partys typically consume 30% more pizza than average. 332 pizzas needed

Convert to pizzas

332 pizzas ÷ 8 per pizza

Each pizza provides 8 pizzas. 41.5 pizzas (raw)

Add 15% buffer & round up

41.5 × 1.15 = 47.7, rounded up

Always round up and add a buffer. Running out of food is worse than having leftovers! 48 pizzas
