Healthy Weight Calculator
Calculate the healthy weight range for your height using the standard 18.5–24.9 BMI range.
- Lower End (BMI 18.5)56.8 kg (125.3 lb)
- Upper End (BMI 24.9)76.5 kg (168.6 lb)
For your height, a healthy weight spans about 19.7 kg — anywhere in that window keeps your BMI in the normal range.
About the Healthy Weight Calculator
This calculator flips the usual BMI question around. Instead of taking your weight and height and telling you your BMI, it takes your height and works out the full span of weights — from a BMI of 18.5 up to 24.9 — that would count as the 'normal' BMI category. The result is a range, not a single target number.
BMI itself is a blunt instrument — it doesn't distinguish muscle from fat, and a bodybuilder and a sedentary person of the same height can land at very different points in this range for very different reasons. Treat the range as a population-level reference point, not a personal prescription for what you specifically should weigh.
It's a quick way to see where a 'healthy' BMI actually falls in pounds or kilograms for your own height, without doing the algebra yourself or reverse-engineering it from a BMI chart.
The height you enter is processed right in your browser and never saved or sent anywhere — there's nothing to look up later, because nothing leaves your device.
How it’s calculated
The range comes from solving the BMI formula for weight instead of BMI: weight = BMI × height(m)², run once at BMI 18.5 for the lower bound and once at BMI 24.9 for the upper bound.
Frequently asked questions
How is the healthy weight range calculated for a given height?
It plugs your height into the BMI formula twice, solving for weight at a BMI of 18.5 (the low end of normal) and again at 24.9 (the high end), which gives the full range considered normal-BMI for that height.
Does this range account for muscle mass?
No — BMI-based ranges can't distinguish muscle from fat, so a muscular person may fall above this range while carrying a healthy amount of body fat. Body composition measures are more informative than BMI alone in that case.
Is the middle of the range the ideal weight to aim for?
Not necessarily — this shows the full span the BMI system labels 'normal,' not a single optimal number. Where you personally should sit within that range depends on frame, muscle mass, and other factors this calculator doesn't measure.
Why does the range change so much between short and tall people?
Because weight scales with the square of height in the BMI formula, so even a small height difference shifts the healthy-weight window by several pounds or kilograms at each end.
