Ideal weight at 5 ft 1 in, female
Enter your height and sex to see three classic estimates of a healthy weight. The example below is a woman at 5 ft 1 in.
How it works
The three formulas differ only in their numbers. Each adds a set number of kilograms per inch above 60 inches to a base weight for your sex. The range runs from the lowest result to the highest. For a woman at 5 ft 1 in the Miller step is 1.36 kg per inch.
Worked example
Subtract 60 from the height. 5 ft 1 in gives 1 inches. Now use the female numbers. Devine: 45.5 + 2.3 × 1 = 47.8 kg. Robinson: 49 + 1.7 × 1 = 50.7 kg. Miller: 53.1 + 1.36 × 1 = 54.46 kg. In pounds that is 105 lb, 112 lb and 120 lb. The range is 105 to 120 lb.
Common questions
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 5 ft 1 in the three results are 105 lb, 112 lb and 120 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 5 ft 1 in the gap between the lowest and highest is 15 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 5 ft 1 in the range of 105 to 120 lb is a starting point, not a limit.
Is 105 to 120 lb a target I must hit?
No. It is a starting reference for a woman at 5 ft 1 in. Your doctor can tell you what weight suits your own health. For a woman at 5 ft 1 in the range spans 15 lb.
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 5 ft 1 in the formulas add 1 inches above the 60 inch base.
