Calculate Healthy Weight
What Does "Healthy Weight" Actually Mean?
"Healthy weight" isn't a single number — it's a range. For any given height, there's a span of roughly 15–20 kg where your risk of weight-related disease is lowest. This calculator finds that range using the WHO BMI standard of 18.5–24.9.
But here's the important caveat: a number on a scale doesn't tell the full story. A 90 kg rugby player with 12% body fat and a 90 kg sedentary person with 35% body fat have the same weight but very different health profiles. BMI-based "healthy weight" is a useful screening tool, not a definitive diagnosis.
Use this calculator as a starting point. Combine it with waist circumference, body fat percentage, and how you actually feel and perform for a more complete picture.
Healthy Weight Ranges by Height
| Height | Healthy Range (kg) | Healthy Range (lbs) | Midpoint |
|---|---|---|---|
| 155 cm / 5'1" | 44–60 kg | 98–132 lbs | 52 kg / 115 lbs |
| 163 cm / 5'4" | 49–66 kg | 108–146 lbs | 58 kg / 127 lbs |
| 170 cm / 5'7" | 53–72 kg | 118–159 lbs | 63 kg / 138 lbs |
| 178 cm / 5'10" | 59–79 kg | 129–174 lbs | 69 kg / 152 lbs |
| 183 cm / 6'0" | 62–83 kg | 137–184 lbs | 73 kg / 160 lbs |
| 190 cm / 6'3" | 67–90 kg | 147–198 lbs | 78 kg / 173 lbs |
What this means for you: Notice how wide the range is — for someone 170 cm tall, the healthy range spans nearly 20 kg. Where you fall within that range depends on muscle mass, frame size, and genetics. Someone with a large frame and good muscle mass will naturally sit near the top. Don't fixate on the midpoint.
When BMI Gets It Wrong
Athletes and Muscular People
BMI doesn't distinguish muscle from fat. A muscular person with low body fat can register as "overweight" by BMI standards. If you strength train regularly, check your body fat percentage instead — it's a better measure.
Older Adults
Some research suggests a BMI of 23–27 may be optimal for adults over 65. Carrying slightly more weight provides reserves during illness and may protect against frailty. The standard 18.5–24.9 range may be too restrictive for this group.
Different Ethnicities
WHO BMI thresholds were developed primarily from European populations. South Asian, Chinese, and Japanese populations may have higher health risks at lower BMIs. Some countries use adjusted thresholds (e.g., overweight at BMI 23 instead of 25).
"Skinny Fat" Individuals
A person with a normal BMI but high body fat and low muscle mass (sometimes called "normal weight obesity") has elevated metabolic risk despite looking thin. BMI misses this entirely. Check your waist-to-hip ratio for a better picture.
Better Metrics to Use Alongside BMI
| Metric | What It Measures | Healthy Range |
|---|---|---|
| Waist circumference | Abdominal fat (visceral fat risk) | Men: under 94 cm / Women: under 80 cm |
| Waist-to-hip ratio | Fat distribution pattern | Men: under 0.90 / Women: under 0.85 |
| Body fat percentage | Total fat vs lean mass | Men: 10-20% / Women: 18-28% |
| Blood pressure | Cardiovascular health | Under 120/80 mmHg |
No single number tells the full story. A healthy weight on the scale plus a healthy waist circumference is a much stronger indicator than either alone. If your BMI is borderline, check your waist measurement — it's a better predictor of heart disease and diabetes risk.
