How much turkey per person?
The USDA's Food Safety and Inspection Service (FSIS) plans on about 1 pound of whole turkey per person. That sounds like a lot, but a whole bird is part bone, so 1 pound raw gives a normal plate of meat. Cooperative Extension services suggest going up to 1½ pounds per person for hearty eaters or if you want leftovers, and down to about ¾ pound if you don't. A boneless breast has no bone to lose, so about ½ pound per person is enough.
| Appetite | Whole turkey | Boneless breast |
|---|---|---|
| Light, no leftovers | ¾ lb per person | ⅜ lb per person |
| Standard | 1 lb per person | ½ lb per person |
| Hearty or leftovers | 1½ lb per person | ¾ lb per person |
The whole-turkey figures and the standard boneless figure come from FSIS and Extension guidance. The light and hearty boneless figures are Calcist's, scaled by the same ratio.
How it's calculated
Fridge thawing = 1 day per 4 lb, rounded up (FSIS: 24 hours per 4 to 5 lb)
Start thawing = serving day − thawing days
Cold-water thawing = 30 minutes per lb
Roast time at 325°F = FSIS table for that weight
Calcist uses 1 day per 4 pounds, the slower end of the FSIS range, so the turkey is ready in time. If you need more than 24 pounds, it suggests two smaller birds, because the USDA roasting table stops at 24 pounds. The oven time works back from dinner using the longest roast time for the weight plus a 20-minute rest.
Worked example
You're feeding 12 people for Thanksgiving on Thursday, November 26, 2026, and you want leftovers. 12 × 1½ lb = 18 lb. At 1 day per 4 lb, 18 ÷ 4 = 4.5, rounded up to 5 days, so move the turkey to the fridge by Saturday, November 21. In cold water it would take 18 × 30 minutes = 9 hours. An unstuffed 18 lb bird roasts in 3¾ to 4¼ hours at 325°F. For dinner at 3:00 PM, it goes in by 10:25 AM: 4¼ hours plus a 20-minute rest.
USDA thawing times
| Turkey weight | In the refrigerator | In cold water |
|---|---|---|
| 4 to 12 lb | 1 to 3 days | 2 to 6 hours |
| 12 to 16 lb | 3 to 4 days | 6 to 8 hours |
| 16 to 20 lb | 4 to 5 days | 8 to 10 hours |
| 20 to 24 lb | 5 to 6 days | 10 to 12 hours |
Thaw in the refrigerator at 40°F or below. A turkey thawed in the fridge keeps 1 to 2 days, so starting a day early is fine, and it can be refrozen. For cold water, keep the bird in its wrapper, submerged, and change the water every 30 minutes. Cook it right after thawing.
USDA roasting times at 325°F
| Turkey weight | Unstuffed | Stuffed |
|---|---|---|
| 8 to 12 lb | 2¾ to 3 hours | 3 to 3½ hours |
| 12 to 14 lb | 3 to 3¾ hours | 3½ to 4 hours |
| 14 to 18 lb | 3¾ to 4¼ hours | 4 to 4¼ hours |
| 18 to 20 lb | 4¼ to 4½ hours | 4¼ to 4¾ hours |
| 20 to 24 lb | 4½ to 5 hours | 4¾ to 5¼ hours |
These times are for a fully thawed turkey. A turkey is done when a food thermometer reads 165°F in the innermost part of the thigh, the innermost part of the wing and the thickest part of the breast. Stuffing must also reach 165°F in its center. A pop-up timer isn't enough on its own. Let the turkey rest about 20 minutes before carving.
After dinner
Refrigerate leftovers within 2 hours. Cooked turkey keeps 3 to 4 days in the fridge. Reheat leftovers to 165°F, or until hot and steaming.
Limitations
- Ovens vary, and so do birds. Roasting times are a guide; the thermometer decides.
- FSIS gives whole-turkey roasting times from 8 to 24 pounds. Outside that range, and for boneless breasts and roasts, follow the package and check the temperature.
- Frozen pre-stuffed turkeys should be cooked from frozen, following the package. FSIS suggests about 1¼ pounds per person for them.
- If you're serving a second main dish, such as ham, you can plan on the smaller amount.
