Calculating Your Healthy Weight Range
Discover your healthy weight range based on height. Learn how to calculate standard targets and set realistic goals.
A healthy weight range is defined as the span of body weights that corresponds to a normal BMI score (between 18.5 and 24.9) for a given height. Setting weight goals within this range helps minimize the risk of weight-related health conditions.
Formula & Math Principles
We calculate the lower and upper bounds of a healthy weight by rearranging the BMI equation:
How to Calculate (Step-by-Step)
To determine your healthy weight range:
- Measure your height in meters (e.g., 1.70 m) and square the value: (1.70)² = 2.89.
- Multiply by 18.5 to find your minimum healthy weight: 18.5 * 2.89 = 53.5 kg.
- Multiply by 24.9 to find your maximum healthy weight: 24.9 * 2.89 = 72.0 kg.
- Your healthy weight range is 53.5 kg to 72.0 kg (118 lbs to 159 lbs).
Practical Examples & Scenarios
Weight Range for 5'6" Height
Calculating the healthy weight range for an individual standing 5 feet 6 inches (1.68 m) tall.
Squaring the height (1.68)² yields 2.8224. Multiplying by the limits gives a healthy range of 115 to 155 pounds.
Healthy Weight Ranges by Height
| Height | Minimum Weight (BMI 18.5) | Maximum Weight (BMI 24.9) | Ideal Target (Devine) |
|---|---|---|---|
| 5'2" (1.57 m) | 101 lbs (45.8 kg) | 135 lbs (61.2 kg) | 112 lbs (50.8 kg) |
| 5'5" (1.65 m) | 111 lbs (50.3 kg) | 149 lbs (67.6 kg) | 128 lbs (58.1 kg) |
| 5'8" (1.73 m) | 122 lbs (55.3 kg) | 164 lbs (74.4 kg) | 145 lbs (65.8 kg) |
| 5'11" (1.80 m) | 132 lbs (59.9 kg) | 178 lbs (80.7 kg) | 163 lbs (73.9 kg) |
| 6'2" (1.88 m) | 144 lbs (65.3 kg) | 194 lbs (88.0 kg) | 180 lbs (81.6 kg) |
Common Pitfalls & Mistakes
- Striving for the minimum healthy weight limit without considering bone density and frame size.
- Setting unrealistic targets that do not account for muscle mass and body composition.
Frequently Asked Questions
How do I determine my body frame size?
Measure the circumference of your wrist relative to your height to classify your frame as small, medium, or large.
Can a healthy weight range change with age?
Yes. As muscle density naturally decreases with age, target ranges are often adjusted upward for older adults.
Conclusion
Use the calculated range as a guide for healthy living, and consult with professionals to establish custom goals.
