An approximate guide. Ovens and birds vary, so go by a thermometer in the thickest part of the thigh, not by the clock.

The math behind it: Turkey Size and Cooking Time

turkey weight = adults x 1 lb (1.5 lb with leftovers) + children x half as much

For 8 adults and 2 children with leftovers, buy a 14 lb turkey. Unstuffed at 325 F it roasts for about 3 hours to 3 hours 45 minutes, and it needs 4 days to thaw in the refrigerator.

Treat the times as an approximate guide. Ovens and birds differ, so the only reliable test is a thermometer: the turkey is done when the thickest part of the thigh reaches 165 F (74 C).

Common questions

How big a turkey do I need per person?

Allow 1 lb per adult, or 1.5 lb if you want leftovers, and half as much for children. Ten adults with no leftovers need a 10 lb turkey.

How long does it take to cook a turkey?

At 325 F, an unstuffed 10 lb turkey takes about 2 hours 45 minutes to 3 hours, and a 14 lb turkey about 3 hours to 3 hours 45 minutes. A stuffed bird takes 15 to 30 minutes longer.

How long does a turkey take to thaw?

In the refrigerator, allow one day for every 4 lb: 3 days for a 12 lb bird and 4 days for 14 to 16 lb. In cold water, changed every 30 minutes, allow 30 minutes per pound.
