📐 Why This Amount Works

Estimate actual eaters

150 guests × 85% eating rate

At large events, about 85% of guests will eat full servings. 128 eaters

Calculate servings (as main dish)

128 eaters × 8 pieces per person

As a main dish, plan for 8 pieces per person. 1024 base servings

Apply birthday party modifier

× 0.9 (-10% for appetizers)

Birthday Partys typically consume 10% less appetizers than average. 918 pieces needed

Convert to platters

918 pieces ÷ 30 per platter

Each platter provides 30 pieces. 30.6 platters (raw)

Add 15% buffer & round up

30.6 × 1.15 = 35.2, rounded up

Always round up and add a buffer. Running out of food is worse than having leftovers! 36 platters
