Healthy Weight for Height Calculator
Find the healthy weight range for your height from the WHO healthy BMI band (18.5–24.9), with a midpoint target and the weight thresholds for every BMI category.
Rather than a single “perfect” number, a healthy weight is best thought of as a range. This healthy body weight calculator turns the World Health Organization’s healthy BMI band (18.5 to 24.9) into concrete weights for your height, then adds a midpoint target and the weight at every BMI category boundary. Enter your height in centimeters or feet and inches — the calculator converts automatically and shows results in kilograms or pounds.
Your healthy range
The main result is the span of weights that keep your BMI in the healthy band for your height. The midpoint target sits in the middle of that range (a BMI of about 21.7) — a sensible single figure to aim for if you want one, while the range gives you room for a normal, healthy build.
The full BMI-category table
Under the range, the calculator lists the weight thresholds for each BMI category at your height — underweight, healthy, overweight, and obese. Seeing the actual weights (not just BMI numbers) makes it easy to know exactly where the boundaries fall for you.
Range vs single target
If you’d rather compare classic single-number formulas, the ideal body weight calculator runs Devine, Robinson, Miller, Hamwi, and the modern Peterson equation side by side. This tool takes the complementary approach — a BMI-based band — which many people find more realistic, since healthy people come in a range of weights for any given height. To see where your current weight lands on that band, the BMI calculator plots it directly. And if you land above the range, the healthy weight loss calculator sets a realistic pace for getting back into it.
What a healthy weight doesn’t capture
BMI-based ranges use only height and weight, so they can’t tell muscle from fat. A muscular athlete may read as “overweight” while being lean and healthy, and an older adult with low muscle may read as “healthy” while carrying excess fat. Use the range as a starting point and combine it with body fat percentage and waist-to-hip ratio for the complete picture.
Frequently asked questions
What is a healthy weight for my height?
A healthy weight is a range, not a single number. It's defined here as the weights that put you in the WHO healthy BMI band of 18.5 to 24.9 for your height. Taller people have a wider range; the calculator shows both the lower and upper healthy weight and a midpoint target.
How do I calculate a healthy weight?
Multiply your height in meters by itself, then multiply by 18.5 for the lower bound and 24.9 for the upper bound. For 175 cm (5 ft 9 in), that's 18.5 × 1.75² ≈ 56.7 kg and 24.9 × 1.75² ≈ 76.3 kg — roughly 125 to 168 lb. The calculator does this for you in kilograms or pounds.
How is this different from an ideal weight calculator?
The ideal weight calculator compares several historical formulas (Devine, Robinson, Miller, Hamwi, Peterson) that each give a single target figure. This healthy weight calculator instead gives the full BMI-based range plus the weight at every category boundary, which is often more practical because it accommodates different builds.
Does a healthy weight depend on age or sex?
The WHO healthy BMI band (18.5–24.9) is the same for adult men and women and doesn't change with age, so this calculator uses height alone. Body composition does differ by sex and age, so pair the range with body fat percentage for a fuller picture. For children and teens, use the child BMI percentile calculator instead.
I'm very muscular — the range says I'm overweight. Is that right?
BMI-based ranges don't distinguish muscle from fat, so athletes and very muscular people can sit above the 'healthy' range while being perfectly healthy. If that's you, a body fat percentage or waist measurement is a better guide than the scale.
