How We Calculate
This calculator uses medically reviewed formulas verified by our team. All calculations are performed instantly in your browser using JavaScript — no data is sent to any server.
We use WHO-recommended formulas and medical standards for health calculations. Results are estimates, not medical advice — always consult a doctor for health decisions.
When to Use This Calculator
Use the healthy weight calculator to establish a realistic target weight for your height before starting a diet or fitness programme, or to check where you currently stand. In India, where the Asia-Pacific cutoffs are widely used, seeing both ranges in one place is genuinely useful: someone who is 'normal' by WHO may already be past the recommended limit by Indian standards, and this tool makes that visible. The optional weight input turns the range into a personal report — your BMI and exactly how many kilograms above or below the band you are — which makes goal setting concrete for weight loss or gain. Doctors and dietitians frequently start consultations with exactly these numbers, so arriving with them already calculated saves time.
How to Use This Calculator
- Step 1: Enter your height in centimetres.
- Step 2: Optionally enter your current weight to see your BMI and position in the range.
- Step 3: Read the WHO healthy weight range (BMI 18.5–24.9).
- Step 4: Compare it with the Asia-Pacific range, which uses a lower upper limit for Indian adults.
Worked Example
For a height of 170 cm, the WHO range runs from 53.5 kg to 72.0 kg, the product of BMI 18.5 and 24.9 with the height squared. The Asia-Pacific scale, which caps at BMI 22.9 for South Asians, shows a tighter range ending at 66.2 kg. If that person weighs 82 kg, the calculator reports a BMI of 28.4, about 10 kg above the WHO upper limit and 15.8 kg above the Asia-Pacific ceiling. At 60 kg and 165 cm, the BMI is 22 — comfortably inside both ranges. Every number is direct BMI arithmetic from the height entered.
Tips and Common Mistakes
- •Tip 1: Weigh yourself in the morning, after visiting the toilet and before breakfast, for consistent comparisons.
- •Tip 2: If you are muscular, take the range with a pinch of salt and look at body fat percentage instead.
- •Tip 3: Treat the range as a target zone — aiming for the middle is generally more sustainable than chasing either extreme.
- ✗Mistake 1: Believing any weight inside the range is automatically healthy — lifestyle, muscle and fat distribution still matter.
- ✗Mistake 2: Ignoring the Asia-Pacific scale if you are of South Asian descent, since the WHO range can understate risk.
Frequently Asked Questions
How is a healthy weight determined?
It is usually defined by BMI — weight divided by height squared. The WHO range of 18.5–24.9 corresponds to a specific weight band for each height; for 170 cm that is about 53.5–72 kg.
Why is there a separate Asia-Pacific range?
People of South Asian origin carry more body fat at the same BMI, so experts often use a lower overweight cutoff (BMI 23) in India. The calculator shows both ranges so you can compare.
Is the lower end of the range always safe?
Not necessarily. Very low body weight carries its own health risks, and the healthy band assumes a normal frame and muscle level. Extremes in either direction should be discussed with a doctor.
I'm muscular — does this range still apply to me?
BMI cannot tell muscle from fat, so a muscular person can show a BMI above 25 while carrying little fat. The range is a screening tool; body fat percentage tells a fuller story.
How should I use the 'current weight' input?
Adding your weight lets the calculator show your BMI and how many kilograms above (or below) the healthy range you are. That gives a concrete, personal target without needing extra inputs.
