CalcVitalsHealthy Weight Range Calculator
Your healthy weight range is the weights that put your BMI between 18.5 and 24.9. At 175 cm that range is 56.7 to 76.3 kg — a wide band, because healthy bodies at one height come in many shapes.
How it works
Most weight charts are really this one idea drawn as a table: for each height, the weights whose BMI falls in the World Health Organization's healthy band, 18.5 to 24.9. This page simply does the arithmetic for your exact height instead of making you interpolate between rows of someone else's chart.
Notice how wide the band is — about 20 kg at average heights. That width is honest. Within it you will find marathon runners and rugby players, narrow frames and broad ones, all at weights their doctors are content with. Where you sit best inside the range depends on your build, your muscle mass and your metabolic health, none of which a height chart can see.
The thresholds above the range are worth knowing too: overweight begins at a BMI of 25 and obesity at 30, and those two lines, in kilograms for your height, are printed with your result. If you are near a boundary, the waist-to-height ratio on this site is a good second opinion, because it responds to the abdominal fat that drives most of the risk.
The method
Range = 18.5 × height(m)² to 24.9 × height(m)², the WHO healthy BMI band converted to kilograms. Overweight and obesity thresholds use BMI 25 and 30 the same way. Intended for adults; children use growth percentiles instead.
Frequently asked questions
Why is the healthy range so wide?
Because it has to cover every healthy body at that height — different frames, muscle mass and proportions. Twenty kilograms of legitimate variation is normal, and it is why a single 'ideal weight' figure is less useful than the band.
I'm above the range but muscular. Should I worry?
BMI-based ranges cannot distinguish muscle from fat, so a muscular build can sit above the band with healthy body composition. A body fat or waist measurement gives the clearer picture in that case.
Does the range change with age?
The official band does not, though some researchers argue a slightly higher range suits older adults. For personal guidance past 65, a clinician's view beats any chart.
