Note: This assumes tacos is your main food. If serving multiple foods, reduce this amount by 30-40%.

📐 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 tacos per person
As a main dish, plan for 3 tacos per person. 255 base servings
3
Apply birthday party modifier
× 1 (0% for tacos)
Birthday Partys have standard tacos consumption. 255 tacos needed
4
Convert to dozen
255 tacos ÷ 12 per dozen
Each dozen provides 12 tacos. 21.3 dozen (raw)
5
Add 15% buffer & round up
21.3 × 1.15 = 24.5, rounded up
Always round up and add a buffer. Running out of food is worse than having leftovers! 25 dozen

💡 Pro Tips for Birthday Party Food

  • Cake reduces other food consumption by 20% - factor this into your planning.
  • Kids' birthday parties need 30% less food per person - shorter attention spans.
  • Adult milestone birthdays (30, 40, 50) eat more - people linger longer.
  • Late-night birthdays need late-night food - pizza arrives around 10pm.
  • Set up food before activities and cake - people graze while waiting.

Buying Guide

Birthday party food depends heavily on the age group. Kids' parties: pizza and simple finger foods. Young adult birthdays: pizza, wings, and shareable platters. 40+ birthdays: more sophisticated appetizers and seated options.
