Based on 1.25 lbs per person (some leftovers), cooked at 325°F unstuffed, thawed in the fridge (24 hours per 5 lbs).

How It Works

The standard rule is 1 to 1.5 pounds of whole turkey per person. That accounts for the bone, carcass, and cooking shrinkage — roughly 35% of the raw weight. If you want leftovers for sandwiches and soup, go with 1.5 lbs per person. For a tight calculation with no waste, 1 lb per person works.

  1. Enter the number of guests at your table.
  2. Pick your leftover preference — this adjusts the per-person weight from 1.0 to 1.5 lbs.
  3. The calculator shows the turkey size to buy, fridge thaw time (24 hours per 5 lbs), and estimated cook time at 325°F.

For groups over 15 people, consider buying two smaller turkeys (12-14 lbs each) instead of one large bird. Two turkeys cook faster, fit in a standard oven, and give you more drumsticks.

Thaw Time Chart

Always thaw turkey in the fridge at 40°F or below. The cold water method (submerged, changing water every 30 minutes) is faster but requires more attention. Never thaw on the counter — the outer layers reach the danger zone (40-140°F) long before the center thaws.

Cooking Temperature Guide

Roast at 325°F (163°C) for even cooking. Some cooks start at 450°F for 30 minutes to crisp the skin, then drop to 325°F for the rest. Either way, the turkey is done when a thermometer inserted into the thickest part of the thigh reads 165°F (74°C). The breast will also read 165°F, but check the thigh — it is thicker and takes longer.

FAQ

How many pounds of turkey per person?

Plan for 1.25 lbs per person as a baseline. That gives each guest about 6-8 oz of cooked meat plus enough for a round of leftover sandwiches. Go to 1.5 lbs per person if your crowd loves seconds or you want leftovers for turkey soup.

Can I cook a frozen turkey without thawing?

Yes — the USDA says it is safe. Cooking from frozen takes about 50% longer than a thawed turkey. A 12 lb frozen turkey takes about 4.5-5 hours at 325°F. You cannot brine or season the cavity, so flavor will be milder. Remove the giblet bag once the turkey thaws enough during roasting.

Should I stuff the turkey?

A stuffed turkey takes about 15-30 minutes longer per pound than an unstuffed one. The stuffing must also reach 165°F in the center, which often means overcooking the breast. For food safety and juicier meat, most experts recommend cooking the dressing separately in a baking dish.

What if my turkey is too big for the oven?

Standard home ovens fit turkeys up to about 24-26 lbs. If you need more than 24 lbs, buy two smaller birds. Two 14 lb turkeys fit side by side and cook faster than one 28 lb bird. You also get four drumsticks instead of two.
