Five lines of arithmetic
Change any assumption you disagree with; the answer follows.
| Estimate actual eaters | 40 guests × 90% eating rate | 36 eaters |
| Calculate servings (as main dish) | 36 eaters × 3 pizzas per person | 108 base servings |
| Apply Thanksgiving modifier | × 0.3 (-70% for pizza) | 32 pizzas needed |
| Convert to pizzas | 32 pizzas ÷ 8 per pizza | 4 pizzas (raw) |
| Add 15% buffer & round up | 4 × 1.15 = 4.6, rounded up | 5 pizzas |
Every constant behind this figure is published, including the eating rate by guest count and the 15 percent buffer; read the methodology.
Pizza for a Thanksgiving, by guest count

| 75 guests | 9 pizzas | 61 |
| 100 guests | 12 pizzas | 77 |
| 150 guests | 17 pizzas | 115 |

- Turkey is sized by weight per guest, and a bone-in bird weighs more than it actually serves.
- Appetizers before dinner should stay light, since the meal is the point.
- Count side dishes for the table as a whole, not for each guest.
- Dessert is non-negotiable - 1 pie per 6-8 guests.
- Leftovers are part of Thanksgiving - plan for turkey sandwiches.
Thanksgiving is about the traditional spread: turkey, stuffing, mashed potatoes, gravy, cranberry sauce, and pie. Light appetizers before dinner only. Plan for leftovers!
