Exact Count, Cost & Event-Type Chart

Kids vs. Adults: How the Mix Changes Your Count
Kids eat roughly half as much as adults. Use this table when your 40-person group includes children (ages 5–12):
| Group Composition | Adults | Kids | 14" Pizzas | Cost (standard) |
|---|---|---|---|---|
| All adults | 40 | 0 | 15 | $318 |
| Mostly adults | 30 | 10 | 13 | $276 |
| Half & half | 20 | 20 | 12 | $254 |
| Mostly kids | 10 | 30 | 10 | $212 |
| All kids (ages 5–12) | 0 | 40 | 8 | $170 |
Formula for mixed groups: (adults × 3 + kids × 1.5) ÷ 8 = pizzas needed, rounded up. Our kids party pizza guide has more age-specific breakdowns.
14-Inch vs. 16-Inch Pizzas for 40 People

| 14" (large/XL) | 8–10 | 15 | $318–425 | $7.95–10.63 |
| 16" (XL/party) ★ | 10–12 | 12 | $270–380 | $6.75–9.50 |
Switching to 16-inch pizzas reduces both the number of boxes to handle and the total cost. For 40 people, you need 3 fewer pizzas with 16-inch compared to 14-inch — saving $40–60 on the total bill while delivering more pizza per dollar. See our 14-inch vs. 16-inch comparison for the full analysis.
