At 75kg the healthy heights run from 174 to 201cm. That upper bound has just crossed two metres, which is worth noting: above 75kg, the tallest height at which this weight still counts as healthy exceeds the height of almost anyone. In practical terms the band stops being bounded above by anything a person is likely t..

FULL SUMMARY
WHO BMI CATEGORIES
The weight is already set to 75kg, which is about 165 pounds. Enter your height and the BMI follows — until you do, the figure is undetermined.
Both unit systems are seeded, so switching between kilograms and pounds keeps the same weight rather than reverting to a default.
Read the band of heights rather than any single BMI. At 75kg the healthy band runs 174 to 201cm, and that band is what a weight actually determines.
A reading near a category boundary should be read as near a boundary. Most people vary by one to two kilograms across a day from food and fluid alone.
At 75kg — about 165 pounds — the BMI is undetermined until a height is supplied. At 150cm it is 33.3, at 175cm 24.5, and at 200cm 18.8: a spread of 14.6 points from one unchanged weight, which is wider than the entire healthy band. Inverting the formula gives what a weight can determine: 75kg sits inside the healthy BMI band for heights between 174cm and 201cm, a window 27cm wide, or roughly 5ft 8in to 6ft 7in. On the WHO 2004 cut-offs for South and East Asian populations the shortest suitable height rises to 181cm, because those thresholds lower the top of the BMI band while leaving 18.5 in place.
FORMULA REFERENCE TABLE
| Name | Formula | Description |
|---|---|---|
| BMI (Metric) | BMI = weight(kg) / height(m)² | Divide weight in kg by height in metres squared |
| BMI (Imperial) | BMI = 703 × weight(lbs) / height(in)² | Multiply weight in pounds by 703, divide by height in inches squared |
| Height in metres | h(m) = h(cm) / 100 | Convert centimetres to metres before squaring |
| BMI Prime | BMI Prime = BMI / 25 | Ratio of BMI to upper limit of normal (25). Values >1.00 indicate overweight |
| Ponderal Index | PI = weight(kg) / height(m)³ | More accurate than BMI for very tall or short individuals. Normal: 11–15 kg/m³ |
| Healthy weight | w = BMI × height(m)² | Rearranged BMI formula: weight(kg) for any target BMI at your height |
