What is Healthy Weight Calculator?
The Healthy Weight Calculator defines the lower and upper bounds of adult body weight that correspond to a normal BMI (18.5 to 24.9 kg/m²), which is statistically associated with lowest cardiovascular morbidity.
How to Use This Calculator
- Enter your height in feet and inches.
- The calculator derives the minimum, maximum, and median target weights.
- Compare against your current scale weight to establish sustainable milestones.
The Mathematical Formula & Variables
Min Weight = 18.5 * Height^2 / 703; Max Weight = 24.9 * Height^2 / 703
Variables Definition
| Symbol / Variable | Name | Description |
|---|---|---|
18.5 |
Lower WHO Cutoff | Minimum threshold for adequate adipose/lean reserve. |
24.9 |
Upper WHO Cutoff | Threshold above which overweight risks increase. |
Step-by-Step Worked Example
Scenario: Adult standing 5 ft 10 in (70 inches tall).
- 70 inches squared = 4,900.
- Minimum healthy weight = (18.5 * 4,900) / 703 = 128.9 lbs.
- Maximum healthy weight = (24.9 * 4,900) / 703 = 173.6 lbs.
Result: Healthy Range: 129 to 174 lbs
Frequently Asked Questions
What if I am muscular and weigh more than the maximum?
Athletes with high skeletal muscle mass can safely exceed the upper BMI limit because lean muscle tissue does not confer the cardiovascular risks of excess visceral adiposity.
