About This Calculator
Our Thanksgiving Dinner Calculator helps you plan the perfect holiday meal by calculating exactly how much food you need based on the number of adults and children attending. Simply enter your guest counts and tell us whether you want leftovers, and the calculator instantly provides precise quantities for turkey, stuffing, mashed potatoes, cranberry sauce, veggie sides, dinner rolls, pies, wine, cheese, and appetizers.
The calculator uses standard Thanksgiving dinner planning guidelines: 1 lb of bone-in turkey per adult and 1/2 lb per child, with a 30% adjustment if you want leftovers. Side dish quantities follow typical serving sizes — 1/2 cup of stuffing per adult, 3/4 cup of mashed potatoes, 1/4 cup of cranberry sauce, and 1/2 cup of veggie sides. We assume 1.5 dinner rolls per adult, one 9-inch pie per 8 adults, and half a bottle of wine per adult. Children are estimated at half the adult portion for most items.
For example, a Thanksgiving dinner for 10 adults and 3 children without leftovers requires approximately 11.5 lb of turkey, 5.75 cups of stuffing, 8.6 cups of mashed potatoes, 2 pies, 18 rolls, and 5 bottles of wine. With leftovers selected, the turkey increases to about 15 lb for extra sandwiches and soups the next day. All quantities are estimates — adjust based on your family's appetites and the number of other dishes being served.
Thanksgiving Planning Tips
Start thawing your turkey 24 hours per 4-5 lb in the refrigerator (allow 3-4 days for a 12-16 lb bird). Prep side dishes the day before to reduce oven time on Thanksgiving Day. Roast the turkey at 325°F (163°C) for 13 minutes per pound unstuffed or 15 minutes per pound stuffed. Let the turkey rest 20-30 minutes before carving. Use our Turkey Cooking Time Calculator for precise cooking times and our Turkey Size Calculator for more detailed sizing options.
