Count on 1.5 pounds when deciding how much turkey per person to buy
Plan 1.5 pounds of whole turkey per guest, or 2 for leftovers. Here's the bird size for 4 to 16 people, USDA fridge and cold water thaw times, roasting times at 325°F, and what the extra half pound costs.

Buy 1.5 pounds of whole turkey for every guest and you'll feed the table with a little to spare. That's the rule Food Network gives for how much turkey per person, and it holds up because a raw bird is a lot of bone, skin and drippings that never reach a plate.
Thanksgiving falls on November 26 this year, so the clock is already running. Getting the size right is only half the job. A frozen 20 pound bird needs 4 to 5 days in the fridge to thaw, which means the buying decision and the thawing plan have to happen together.
How much turkey per person you should actually buy
Weight on the label is raw, bone-in weight. At 1.5 pounds per guest, that's about 680 grams of whole bird per person, and only a portion of it ends up as sliced meat. If you think in metric, our grams to ounces converter makes the label math quick.
The 1.5 pound rule for most tables
Food Network's example is a good gut check: 8 guests need at least 12 pounds, so a 14 pound turkey is the safer pick. Rounding up to the next bird size costs a few dollars and saves you from carving thin slices to stretch it.
When 2 pounds makes sense
Some chefs plan 2 pounds per person in case your guests all want white meat, or all want dark. For 10 people that's a 20 pound turkey. Food Network calls 2 pounds the most you'll ever need, since everyone also loads up on sides.

How big of a turkey do I need for my guest count?
Here's the math worked out so you don't have to do it in the store aisle. The middle column is the standard rule and the right column covers leftovers. Pick the bird that meets or beats your number.
| Guests | Standard | With Leftovers |
|---|---|---|
| 4 | 6 lb | 8 lb |
| 6 | 9 lb | 12 lb |
| 8 | 12 lb | 16 lb |
| 10 | 15 lb | 20 lb |
| 12 | 18 lb | 24 lb |
| 16 | 24 lb | 32 lb |
Once you pass about 24 pounds, look at two birds. Food Network suggests two smaller turkeys over one huge one for big gatherings, and the USDA thawing and roasting charts stop at 24 pounds anyway. Two 12 pound birds also thaw in 1 to 3 days each instead of a week.

How long to thaw a turkey without blowing your schedule
The USDA rule is about 24 hours in the fridge for every 4 to 5 pounds, with the fridge at 40°F or colder. That's the safest method and the slowest. The tables below come from the UGA Extension guide, which follows the USDA numbers.
How long to thaw turkey in fridge, by weight
A thawed turkey can sit in the fridge for another 1 to 2 days before you cook it, so starting early is low risk. Count back from November 26: a 24 pound bird should go in the fridge by Friday, November 20, and a 16 pound bird by Sunday, November 22.
Cold water thawing when you're behind
Forgot to move it? Keep the turkey in a leak-proof bag, submerge it in cold tap water, and change the water every 30 minutes. Plan on roughly 30 minutes per pound, and cook it right away once it's done.
A 20 pound turkey takes 4 to 5 days to thaw in the fridge but only 8 to 10 hours in cold water. The catch is you're changing that water every half hour.

Turkey cooking time per pound at 325°F
Roasting time scales with weight, but not in a straight line. A 12 pound bird takes about 3 hours unstuffed at 325°F, while a 24 pound one needs closer to 5. These are the UGA Extension estimates for an unstuffed whole turkey.
Times are a starting point, not a finish line. The bird is done at 165°F, checked in the thickest part of the breast, the innermost thigh and the wing joint. Let it rest 20 minutes before carving. If you brined it, our salt guide for turkey brine covers the weights.
What the extra half pound per person costs
The American Farm Bureau priced a 16 pound frozen turkey at $21.50 in its 2025 survey, which works out to $1.34 a pound and was 16.3% cheaper than the year before, according to The Provisioner. Your store will differ, but it's a useful yardstick.
At that price, a 15 pound bird for 10 guests runs about $20.10, or roughly $2 a head. Bumping up to 20 pounds for leftovers adds about $6.70. That's cheap insurance, and Friday's sandwiches are basically free.
At $1.34 a pound, going from 1.5 to 2 pounds per guest adds about 67 cents per person. Running short on turkey costs a lot more in stress.
Where people overspend is the giant bird. A 28 pound turkey for 14 guests is more than the 2 pound ceiling, and it's past the USDA charts for thawing and roasting. Two 14 pound birds are easier to fit in the fridge and cook more evenly.

Turkey size per person and other last-minute questions
How many pounds of turkey per person for a boneless roast?
About 8 ounces per guest, since there's no bone to subtract. That's roughly 227 grams of raw meat per person, so a 3 pound boneless roast covers 6 people.
What size turkey do I need for 4 people?
By the 1.5 pound rule you need 6 pounds, or 8 if you want leftovers. If the smallest whole bird at your store is much bigger, a bone-in breast in the 4 to 8 pound range is a sensible swap, and the USDA chart roasts it in 1½ to 3¼ hours.
How long to defrost turkey if it's still frozen Thursday morning?
Cold water is your only real option, at about 30 minutes per pound. A 12 pound turkey needs around 6 hours of water changes before it can even go in the oven, so an early dinner may become a late one.
