BMI Calculator (Nepal)

Calculate your Body Mass Index using WHO classification. Find your ideal weight range based on your height. Inputs in metric or imperial.

Your measurements

Height

Weight

Gender (for context)

BMI thresholds are the same for both genders, but body composition differs. Women typically have higher healthy body-fat percentages than men.

Your BMI

22.5

Normal

Healthy weight range.

Ideal weight range

53.5 – 72.0 kg

For your height (170 cm), this is the BMI 18.5–24.9 range.

WHO BMI Classification

Category	BMI Range	Description
Underweight	< 18.5	May indicate undernutrition. Common in Nepal — check protein intake.
Normal	18.5 – 25	Healthy weight range.
Overweight	25 – 30	Increased risk of cardiovascular issues.
Obese class I	30 – 35	Higher health risks. Consult a doctor.
Obese class II	35 – 40	Significant health risks.
Obese class III	≥ 40	Severe risks. Medical consultation recommended.

Context for Nepal: According to the Nepal Demographic and Health Survey, roughly 17% of Nepali women and 12% of men are underweight (BMI < 18.5), while about 22% of women and 17% of men are overweight or obese. Urban populations (Kathmandu, Pokhara, Birgunj) skew toward overweight; rural populations skew toward underweight. BMI is a screening tool — for body composition or athletic build, waist-to-hip ratio and body-fat percentage are better measures.

Frequently Asked

How is BMI calculated?

BMI = weight (kg) ÷ height² (m²). So someone 170cm (1.7m) tall weighing 65kg has BMI = 65 / (1.7 × 1.7) = 22.5, which is in the normal range. The formula is the same worldwide.

Is BMI accurate for Nepali / South Asian body types?

The WHO has noted that South Asian populations may face elevated cardiovascular risk at lower BMI than European populations. Some doctors use 23 (instead of 25) as the overweight threshold for South Asians. For a quick screening, the standard scale above is fine; for individual diagnosis, talk to a doctor about your specific risk factors.

What's the BMI difference between men and women?

The BMI thresholds are the same, but body composition differs: women naturally have ~5-10% more body fat than men at the same BMI. So a man with BMI 24 and a woman with BMI 24 typically have different fat-to-muscle ratios.

Does BMI work for athletes or bodybuilders?

Not well — muscle is denser than fat, so a fit athlete can have a high BMI without being unhealthy. If you lift weights or have a muscular build, ignore BMI and use body-fat percentage instead.

What about children and elderly?

This calculator is for adults (18-65). Children use age-and-sex-specific BMI percentile charts (different from adult BMI). The elderly may need adjusted thresholds since healthy weight ranges shift with age — consult your doctor.
