How Big a Turkey Do I Need? Turkey Size, Thaw and Cooking Time Calculator

USDA guidance last checked October 23, 2026.

For 12 people, a whole turkey should weigh about 12 lb, or 16 lb with your leftover servings, at USDA's 1 lb per person.

1. Who is eating

USDA's rule is per person and does not split adults and kids.

Each extra serving gets the same per-person amount.

WhenWhat to do
Sun, Nov 22, 10:15 AM
Thaw
Move the frozen turkey to the refrigerator
Do it by this time. USDA: about 24 hours for every 4 to 5 pounds in a refrigerator at 40 F or below, so 3 days 4 hours to 4 days for 16 lb. Starting a little earlier is fine, back to about Sun, Nov 22, 5:15 AM: USDA says a thawed turkey can stay in the refrigerator 1 to 2 days, and this uses the 1. Keep it in its original wrapper on a tray or in a pan to catch juices.
Thu, Nov 26, 10:15 AM
Oven
Turkey into the oven at 325 F
USDA's 325 F table: 3 hours 45 minutes to 4 hours 15 minutes for 16 lb. Take the giblets out of the cavities first. On a rack in a shallow roasting pan.
Thu, Nov 26, 2:00 PM
Check
Start checking the temperature
It is done when a food thermometer reads 165 F in the innermost part of the thigh and wing and the thickest part of the breast. Do not touch bone. If it is done early, hold it at 140 F or above; USDA says holding food hot longer than 2 hours is not a good idea.
Thu, Nov 26, 2:40 PM
Rest
Out of the oven, rest 20 minutes
Only take it out once all three spots read 165 F. USDA: let it stand 20 minutes before carving.
Thu, Nov 26, 3:00 PM
Eat
Dinner
Carve and serve.
Thu, Nov 26, 4:40 PM
Fridge
Leftovers into the refrigerator by now
USDA: discard turkey, stuffing and gravy left out at room temperature longer than 2 hours (1 hour above 90 F). Cut the turkey into smaller pieces (slice the breast; legs and wings can stay whole) and refrigerate or freeze it in covered shallow containers. Use refrigerated turkey, stuffing and gravy within 3 to 4 days: by Sun, Nov 29 to Mon, Nov 30. Reheat to 165 F.

Safe when a food thermometer reads 165 F in the innermost part of the thigh and wing and the thickest part of the breast (USDA FSIS). Times are USDA's approximate 325 F times; the thermometer has the final say. Start times are rounded down to the quarter hour.

How we got this

  1. Count who is eating, kids as full people (USDA's rule is per person): 10 adults + 2 kids = 12 people
  2. USDA: allow 1 pound of turkey per person: for dinner: 12 people × 1 lb per person = 12 lb (USDA FSIS, Let's Talk Turkey); 12 people + 4 leftover servings = 16 servings; with leftovers: 16 servings × 1 lb per person = 16 lb. Each extra leftover serving gets the same amount.
  3. The plan is for one 16 lb bird, inside USDA's 325 F roasting table (it goes up to 24 lb).
  4. USDA: in the refrigerator, allow approximately 24 hours for every 4 to 5 pounds. Per pound and for this bird, that is 24 hours ÷ 5 lb = 4.8 hours per lb; 24 hours ÷ 4 lb = 6 hours per lb; 16 lb × 4.8 to 6.0 hours per lb = 76.8 to 96.0 hours (USDA FSIS, Let's Talk Turkey, USDA FSIS, Safe Thawing)
  5. USDA's 325 F table gives 3 hours 45 minutes to 4 hours 15 minutes for 16 lb unstuffed. This planner counts back the slow end from Thu, Nov 26, 2:40 PM, 20 minutes before dinner, because USDA says to let the turkey stand for 20 minutes before carving: into the oven: Thu, Nov 26, 2:40 PM − 4.25 hours = Thu, Nov 26, 10:15 AM (rounded down to the quarter hour from 10:25 AM) (USDA FSIS, Let's Talk Turkey)
  6. Count back from when it must be thawed, Thu, Nov 26, 10:15 AM. The earliest start uses the fast end plus 1 day, the short end of USDA's "1 to 2 days" a thawed turkey can remain in the refrigerator; the latest start uses the slow end: 76.8 hours + 24 hours = 100.8 hours; earliest start: Thu, Nov 26, 10:15 AM − 100.8 hours = Sun, Nov 22, 5:15 AM (rounded down to the quarter hour from 5:27 AM); latest start: Thu, Nov 26, 10:15 AM − 96 hours = Sun, Nov 22, 10:15 AM. Into the refrigerator between about Sun, Nov 22, 5:15 AM and Sun, Nov 22, 10:15 AM. (USDA FSIS, Let's Talk Turkey)

The idea behind it: USDA sizes a turkey by the pound per person and times both thawing and roasting by weight, so every number here starts from the weight. The plan then counts backward from dinner, using the slow end of each USDA range so the bird is thawed and out of the oven in time.

Enter your guests and when dinner should be on the table. The planner sizes the bird with USDA's per-person rule, then works backward: when it goes into the fridge (or cold water), when it goes into the oven, when to start checking it, and when the leftovers need to be put away.

How this is calculated

Turkey to buy = (adults + kids, or half a portion each if you choose) x 1 pound, or 1 1/4 pounds for a bird frozen pre-stuffed at the plant (USDA's per-person rule); leftover servings are added at the same rate. The timeline counts back from dinner: a 20-minute rest, then the longest time in USDA's 325 F roasting table for the weight, then the thaw at about 24 hours per 4 to 5 pounds in the refrigerator or 30 minutes per pound in cold water (USDA, Safe Thawing).

The mistake this planner is built to catch

Most turkey charts answer "how long" and leave the scheduling to you. The schedule is where Thanksgiving goes wrong: a 20-pound frozen bird needs 4 to 5 days in the refrigerator, so it has to move out of the freezer on the weekend before. The planner counts back from the minute you want to eat: a 20-minute rest, the longest roasting time in USDA's range so even a slow bird is ready, then the thaw. If the date you need has already passed, it says so and shows what still works, such as cold water or roasting from frozen.

Example: a 16-pound unstuffed frozen turkey for Thanksgiving dinner at Thu, Nov 26, 3:00 PM. It goes into the refrigerator by Sun, Nov 22, 10:15 AM, into a 325 F oven at Thu, Nov 26, 10:15 AM, and you start checking the temperature 3 hours 45 minutes later.

Thanksgiving 2026: when to start thawing, by turkey size

For dinner at 3:00 PM on Thanksgiving, an unstuffed frozen turkey roasted at 325 F, the planner gives these start times. "Into the fridge by" is the latest start for a refrigerator thaw at USDA's slower rate (24 hours per 4 pounds). Much earlier is not better: USDA says a thawed turkey keeps only 1 to 2 more days in the refrigerator. The cold water column is the backup if the bird is still frozen; cook it as soon as it thaws.

How much turkey per person

USDA's rule is 1 pound per person for a whole bird and 1 1/4 pounds for one frozen pre-stuffed at the plant. The middle column adds one leftover serving for every two guests, as an example.

GuestsWhole turkeyWith some leftoversFrozen pre-stuffed
66 lb9 lb7.5 lb

USDA gives no per-person amount for a bone-in breast or a boneless roast, so for those the planner asks for the weight on the label instead of guessing.

Thawing times

Refrigerator: about 24 hours for every 4 to 5 pounds at 40 F or below. Cold water: about 30 minutes per pound, changing the water every 30 minutes, and cook it right after.

TurkeyIn the refrigeratorIn cold water
8 lb1 day 14 hours to 2 daysabout 4 hours
12 lb2 days 9 hours to 3 daysabout 6 hours
14 lb2 days 19 hours to 3 days 12 hoursabout 7 hours

18 lb3 days 14 hours to 4 days 12 hoursabout 9 hours
20 lb4 days to 5 daysabout 10 hours
24 lb4 days 19 hours to 6 daysabout 12 hours

Roasting times at 325 F

USDA says to set the oven no lower than 325 F and publishes times only for 325 F. Times are for a fully thawed or fresh bird; from frozen, add at least 50 percent.

Two USDA pages differ slightly on a stuffed 6 to 8 pound breast (2 1/2 to 3 1/2 hours on one, 3 to 3 1/2 on the other); the table uses the wider span. Weights on a row edge, such as exactly 12 pounds, get the span of both rows. Above 24 pounds USDA lists no time at all.

Frying, grilling or smoking instead? What USDA says

The planner times oven roasting only, using USDA's 325 F table. USDA publishes rough per-pound times for other methods, with tighter limits; all of them need a fully thawed, unstuffed bird, and USDA says not to smoke, grill, deep fry or microwave a frozen turkey (USDA, Alternate Routes to the Table).

MethodUSDA timeLimits USDA sets
Deep fat frying3 to 5 minutes per poundTurkey 12 pounds or less; oil at 350 F; outdoors, never left unattended
Covered gas or charcoal grill15 to 18 minutes per poundAir in the grill held at 225 to 300 F, drip pan with water underneath
Smoker20 to 30 minutes per poundSmoker held at 225 to 300 F; a charcoal smoker needs more charcoal every 1 to 2 hours
Microwave9 to 10 minutes per pound at medium (50%) powerA 12 to 14 pound turkey is the largest most microwaves hold; use an oven cooking bag and rotate it

USDA says grill and smoker times depend on the bird's size and shape, the heat and the outside air, so these are estimates; always use a food thermometer. The finish line does not change: 165 F in the thigh, wing and breast. Note the frying limit: a 16-pound bird from the table above is too big for USDA's 12-pound frying rule.

Done means 165 F in three places

Push a food thermometer into the innermost part of the thigh, the innermost part of the wing and the thickest part of the breast, away from bone. All three need 165 F. If the bird is done before dinner, keep it at 140 F or above; USDA says holding food hot for more than 2 hours is not a good idea. Then let it stand 20 minutes before carving.

Questions people ask

How big of a turkey do I need?

USDA says to allow 1 pound of turkey per person for a fresh or frozen whole bird, and 1 1/4 pounds per person for a turkey that was frozen pre-stuffed at the plant. So 12 people need about a 12-pound bird. That pound is bone-in weight, and it does not include leftovers: add a serving for each extra plate you want afterward. The calculator does that and shows both numbers.

How long does a turkey take to thaw in the refrigerator?

About 24 hours for every 4 to 5 pounds in a refrigerator at 40 F or below, per USDA. A 16-pound bird needs about 3 to 4 days, and a 20-pound bird 4 to 5. After it thaws it can stay in the fridge 1 to 2 more days, so starting a little early is fine; starting late is the usual Thanksgiving problem.

How do I thaw a turkey in cold water?

Keep it in a leak-proof wrapper, put it completely under cold tap water, and change the water every 30 minutes. USDA allows about 30 minutes per pound, so a 14-pound turkey takes about 7 hours and 13 water changes. Cook it as soon as it is thawed. USDA's three safe ways to thaw are the refrigerator, cold water and the microwave; never thaw it on the counter.

Can I cook a turkey that is still frozen?

Yes. USDA says it is safe to cook a turkey from the frozen state; it takes at least 50 percent longer than a thawed bird. Take the giblet packages out with tongs once they loosen during cooking. You cannot stuff a frozen bird, so cook the stuffing in a casserole.

How long do I cook a turkey at 325 F?

USDA's 325 F timetable runs from 2 3/4 to 3 hours for an 8 to 12 pound unstuffed turkey up to 4 1/2 to 5 hours for 20 to 24 pounds. Stuffed birds take longer, up to 5 1/4 hours. The times are approximate: it is done when the thermometer says so, not when the timer goes off.

What temperature is a turkey done?

165 F, measured with a food thermometer in the innermost part of the thigh and wing and the thickest part of the breast, without touching bone. A pop-up timer is not enough on its own, per USDA. If the bird is stuffed, the center of the stuffing must also reach 165 F.

Should I stuff the turkey?

USDA does not recommend it: stuffing inside the bird takes longer to reach a safe temperature and can carry bacteria even when the meat is done. If you do, cook any raw meat or shellfish for it first, mix wet and dry ingredients just before stuffing, stuff loosely (about 3/4 cup per pound), and roast it right away. Never stuff it the night before. The center of the stuffing must reach 165 F, and it stays in the bird until it does.

How long are turkey leftovers good?

Get them into the refrigerator within 2 hours (1 hour if it is above 90 F), cut into smaller pieces in shallow covered containers. USDA says to use refrigerated turkey, stuffing and gravy within 3 to 4 days, or freeze them. Reheat to 165 F.
