Calculate Thanksgiving dinner quantities: turkey size, sides, desserts, and drinks for any guest count. Complete menu planner with timeline.
Planning Thanksgiving dinner is stressful enough without doing math. How big should the turkey be? How many pounds of potatoes? How many pies? This calculator handles the entire menu — turkey, sides, desserts, and drinks — for any number of guests.
The rule of thumb is 1–1.5 pounds of turkey per person (bone-in, uncooked). That accounts for bone weight and cooking shrinkage. For leftover lovers, go 1.5 lbs per person. For big-eater crowds, push to 1.75 lbs. The calculator adjusts for your leftovers preference.
Beyond the turkey, this calculator covers mashed potatoes, stuffing, cranberry sauce, gravy, dinner rolls, green beans, sweet potatoes, and pie. Enter your headcount and get a complete shopping list. It also includes a cooking timeline working backwards from your target dinner time — because the biggest Thanksgiving disaster isn't a dry turkey, it's having everything ready at different times. Check the example with realistic values before reporting.
Thanksgiving involves 8–12 dishes that all need to finish at the same time. This calculator provides quantities for every item and a cooking timeline to coordinate the entire meal. Keep these notes focused on your operational context. Tie the context to the calculator’s intended domain. Use this clarification to avoid ambiguous interpretation. Align this note with review checkpoints.
Turkey: 1.0–1.75 lbs/person (bone-in). Mashed potatoes: ⅓ lb/person. Stuffing: ⅓ cup/person. Gravy: ⅓ cup/person. Cranberry sauce: ¼ cup/person. Rolls: 1.5/person. Pie: 1 pie per 8 guests. Green beans: ¼ lb/person. Sweet potatoes: ¼ lb/person.
Result: 16 lb turkey, 5 lbs potatoes, 2 pies, 18 rolls
12 guests at 1.25 lbs/person = 15 lbs turkey (round up to nearest even). Potatoes: 12 × 0.33 = 4 lbs + buffer = 5 lbs. Pies: 12 ÷ 8 = 1.5 → 2 pies. Rolls: 12 × 1.5 = 18.
Working backwards from a 4:00 PM dinner: 4 PM: carve and serve. 3:15 PM: turkey rests, make gravy, reheat sides. 11:00 AM: turkey in oven (for 15 lb bird). 10:00 AM: prep stuffing, start potatoes. 9:00 AM: preheat oven, prep green beans. Day before: dry brine turkey, make cranberry sauce, make pie.
Not everyone wants a whole turkey. Two 12 lb turkeys cook 30% faster than one 24 lb turkey. Turkey breast only works for smaller groups (plan 0.75 lb/person). Turducken serves approximately 15–20. A ham alongside a smaller turkey gives variety and relieves pressure on turkey timing.
A proper Thanksgiving produces leftovers. Turkey sandwiches, turkey pot pie, turkey soup. Budget 0.25–0.5 extra lbs per person if you want sufficient leftovers. A 16 lb turkey for 12 people yields about 8 lbs cooked meat — roughly 6 lbs eaten at dinner, 2 lbs for sandwiches.
No leftovers: 1 lb/person. Some leftovers: 1.25 lbs. Generous leftovers: 1.5 lbs. For 12 guests wanting leftovers: 15–18 lb turkey.
In the fridge: 24 hours per 4–5 lbs. A 15 lb turkey needs 3–4 days. Cold water method: 30 min per pound, changing water every 30 min. Never thaw at room temperature.
At 325°F: 12–14 lb = 3–3.75 hours; 14–18 lb = 3.75–4.25 hours; 18–20 lb = 4.25–4.5 hours; 20–24 lb = 4.5–5 hours. Always use a meat thermometer — 165°F in the thickest part of the thigh.
One 9" pie serves 8. For 12 guests, make 2 pies (offer variety: pumpkin + pecan or apple). For 20+ guests, make 3 pies.
Not recommended for best quality. You can, however: prep the turkey (dry brine, season) the night before; make stuffing, cranberry sauce, and pie the day before; prep vegetables the morning of.
Maximum turkey size for a standard 30" oven is about 24 lbs. For very large groups (20+), consider two smaller turkeys (12–14 lbs each) — they cook faster and more evenly.
