At 135kg the BMI is 44.1 at 175cm and 33.8 at two metres. The populations that set the BMI thresholds in the twentieth century contained relatively few people at this weight, which means the relationship between the number and any specific outcome is less firmly established here than in the middle of the distribution...

FULL SUMMARY
WHO BMI CATEGORIES
The weight is already set to 135kg, which is about 298 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 135kg the healthy band runs 233 to 270cm, 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 135kg — about 298 pounds — the BMI is undetermined until a height is supplied. At 150cm it is 60.0, at 175cm 44.1, and at 200cm 33.8: a spread of 26.3 points from one unchanged weight, which is wider than the entire healthy band. Inverting the formula gives what a weight can determine: 135kg sits inside the healthy BMI band for heights between 233cm and 270cm, a window 37cm wide, or roughly 7ft 8in to 8ft 10in. On the WHO 2004 cut-offs for South and East Asian populations the shortest suitable height rises to 243cm, 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 |
