Ideal weight at 6 ft 0 in, female
Three formulas give three answers, and the gap between them is your range. Here they are for a woman standing 6 ft 0 in.
How it works
For males, Devine is 50 kg plus 2.3 kg per inch over 60. For females, it is 45.5 kg plus 2.3 kg per inch. Robinson and Miller use their own bases and steps. The page runs all three. This female page uses 12 inches over the 60 inch base, at 6 ft 0 in.
Worked example
Start with the height. 6 ft 0 in is 12 inches over 60. For a woman, 45.5 + 2.3 × 12 = 73.1 kg is the Devine result. 49 + 1.7 × 12 = 69.4 kg is the Robinson result. 53.1 + 1.36 × 12 = 69.42 kg is the Miller result. Those are 161 lb, 153 lb and 153 lb. The range is 153 to 161 lb.
Common questions
What if I am under 5 feet tall?
The formulas were written for heights of 5 feet and over. Below that the calculator uses the base weight. Treat the result as rough. For a woman at 6 ft 0 in the formulas add 12 inches above the 60 inch base.
How does this compare with BMI?
A healthy BMI range also gives a weight range for your height. The two often overlap but they are not the same, because BMI ignores sex while these formulas use it. For a woman at 6 ft 0 in a healthy BMI is 136 to 184 lb, against 153 to 161 lb here.
Which ideal weight formula is best?
None is better than the others. They were built for different purposes. Showing all three as a range is more honest than picking one. For a woman at 6 ft 0 in the three results are 161 lb, 153 lb and 153 lb.
Why do the formulas give different answers?
Each uses its own base weight and its own amount per inch. The gap grows as height moves away from 5 feet. For a woman at 6 ft 0 in the gap between the lowest and highest is 8 lb.
Do these formulas account for muscle or frame size?
No. They use only height and sex. Someone with a large frame or a lot of muscle can be healthy well above the range. For a woman at 6 ft 0 in the range of 153 to 161 lb is a starting point, not a limit.
