Ideal weight at 4 ft 11 in, female
Three formulas give three answers, and the gap between them is your range. Here they are for a woman standing 4 ft 11 in.
How it works
Every method starts from a base weight at 60 inches and adds kilograms for each extra inch. The bases and the steps differ by sex and by formula. You get three estimates and a range. Below 60 inches the Miller base of 53.1 kg is the whole answer.
Worked example
Take a woman who is 4 ft 11 in tall. That is 1 inch under 60. Each formula adds 0. Devine: 45.5 + 2.3 × 0 = 45.5 kg, or 100 lb. Robinson: 49 + 1.7 × 0 = 49 kg, or 108 lb. Miller: 53.1 + 1.36 × 0 = 53.1 kg, or 117 lb. The range is 100 to 117 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 4 ft 11 in the three results are 100 lb, 108 lb and 117 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 4 ft 11 in the gap between the lowest and highest is 17 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 4 ft 11 in the range of 100 to 117 lb is a starting point, not a limit.
Is 100 to 117 lb a target I must hit?
No. It is a starting reference for a woman at 4 ft 11 in. Your doctor can tell you what weight suits your own health. For a woman at 4 ft 11 in the range spans 17 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 4 ft 11 in the height is under 60 inches. The formulas use their base weights.
