What Is the Turkey Size Calculator?
The Turkey Size Calculator helps you decide how big a turkey to buy for a holiday meal such as Thanksgiving or Christmas. Buying too small leaves guests hungry; buying too large wastes money and fridge space. By entering the number of people you are serving, the tool instantly recommends a turkey weight in both pounds and kilograms.
How to Use It
Enter the number of guests you expect at your table. The default allowance is 1.25 pounds of turkey per person, which accounts for bone weight and leaves a little extra for leftovers. If you want bigger portions or plenty of next-day sandwiches, raise the pounds-per-guest value to 1.5; for a lighter meal lower it toward 1.0. Press calculate to see the suggested whole-bird weight.
The Formula Explained
The calculation is simple multiplication: $$\text{Turkey Weight} = \text{Guests} \times \text{Pounds per Guest}$$ The standard 1.25 lb-per-person figure is a catering rule of thumb that balances generous servings with realistic leftovers. The result is also converted to kilograms by multiplying pounds by \(0.45359237\).
Worked Example
Suppose you are hosting 12 guests at the default 1.25 lb each. The math is $$12 \times 1.25 = 15 \text{ lb}.$$ That equals about \(15 \times 0.45359237 \approx 6.8\) kg. So you should look for a turkey weighing roughly 15 pounds.
FAQ
How much turkey per person should I buy? Around 1 to 1.25 pounds per guest for a whole bird; bump it to 1.5 lb if you love leftovers.
Does this include children? Children eat less, so you can count two small children as one adult guest if you like.
What if my turkey is boneless? For boneless turkey breast, use about 0.5–0.75 lb per person since there is no bone weight.
