📐 Why This Amount Works

1
Estimate actual eaters
100 guests × 85% eating rate
At large events, about 85% of guests will eat full servings. 85 eaters
2
Calculate servings (as main dish)
85 eaters × 3 pizzas per person
As a main dish, plan for 3 pizzas per person. 255 base servings
3
Apply 4th of july party modifier
× 0.7 (-30% for pizza)
4th of July Partys typically consume 30% less pizza than average. 179 pizzas needed
4
Convert to pizzas
179 pizzas ÷ 8 per pizza
Each pizza provides 8 pizzas. 22.4 pizzas (raw)
5
Add 15% buffer & round up
22.4 × 1.15 = 25.8, rounded up
