About the Healthy Weight Calculator
This calculator converts your height into the weight range that corresponds to a normal BMI. Expressing it as a range rather than a single figure is the point — healthy weight spans a genuinely wide band, and anywhere within it is unremarkable.
The formula
Range = 18.5 · height (m)² to 24.9 · height (m)²The lower and upper bounds of the normal BMI category are applied to your height, giving the weight interval that falls inside it.
How to use this calculator
- 1Enter your Height (cm). The field starts at
175, which you can overwrite. - 2Read the result straight away — it recalculates as you type, so there is no button to press. Use Share to copy a link that reopens the page with your exact numbers filled in.
Worked example
| Input | Value |
|---|---|
| Height (cm) | 175 |
Result
Healthy Weight Range:
56.7 kg – 76.3 kg
(124.9 lbs – 168.1 lbs)
Based on BMI 18.5–24.9
Those are the values the page loads with, so you can reproduce this result yourself and then change one field at a time to see what drives the outcome.
Understanding your result
The range is wide by design. For someone 175 cm tall it runs from about 57 to 76 kilograms — nearly 20 kilograms of legitimate variation, reflecting differences in frame size, muscle mass, and build. Anyone claiming a single correct weight for a given height is overstating what the evidence supports.
Where you sit within the band matters less than what your body is composed of and how fit you are. Someone at the top of the range with substantial muscle and good cardiovascular fitness is in better health than someone at the bottom who is sedentary. Blood pressure, blood glucose, lipids, and fitness are the measures that predict outcomes.
Things worth knowing
- Weight fluctuates 1 to 2 kg day to day from hydration, food volume, and hormones. Weekly averages are more meaningful.
- Lower BMI thresholds apply for people of Asian descent, where risk rises from around 23.
- Being at the top of the range with high muscle mass is not the same as being at the top with high body fat.
- Waist circumference adds information BMI cannot capture, particularly about abdominal fat.
- For most people, improving fitness and diet quality produces more health benefit than moving within the range.
Frequently asked questions
What weight should I be for my height?+
A range rather than a number. For 175 cm, roughly 57 to 76 kg falls inside the normal BMI band. Where you sit within it depends on frame size and muscle mass.
Why is the healthy range so wide?+
Because body composition varies enormously at the same height. A 20 kg spread reflects genuine differences in skeletal frame, muscle mass, and build, all of which are compatible with good health.
Should I aim for the middle of the range?+
Not necessarily. There is no evidence that the midpoint is healthier than the edges. Body composition, fitness, and metabolic markers matter far more than your position within the band.
What if I am just outside the range?+
Slightly outside is not in itself alarming, especially if you are muscular or have a large frame. Look at waist circumference, blood pressure, and blood markers, and discuss any concerns with a doctor.
