Healthy weight calculator
Turn height into a healthy-weight range using the standard adult BMI band.
What this calculator covers
Use this calculator to translate a single height into the body-weight range that matches the common adult BMI reference interval of 18.5 to 24.9. The math is simple, but keeping the squared-height step visible makes the result easier to audit.
A healthy-weight range is only a screening shortcut. It does not account for frame size, body composition, or athletic build, so it works best as a rough planning reference rather than a full picture of health.
Frequently asked questions
- How is a healthy-weight range calculated from height?
- The range is derived by solving the standard BMI equation in reverse: weight equals BMI multiplied by height in meters squared. Using the commonly cited adult BMI interval produces a lower and upper weight for any given height.
- Why do the lower and upper bounds feel far apart for tall people?
- Because weight scales with height squared, a small difference in height translates to a wider absolute weight range. A person who is 6 feet tall has a larger healthy-weight window in pounds than someone who is 5 feet tall.
- Does this apply to children or teenagers?
- No. The adult BMI reference interval used here is not appropriate for people under 18, who have different body-composition norms. Pediatric weight assessments use age- and sex-specific growth charts.
- Should I use this result as a weight-loss target?
- The range is a broad population-level screening tool, not a personal health prescription. A doctor or registered dietitian can give guidance that accounts for your individual body composition, health history, and goals.

Primary result
56.7-76.3 kg
At 175.0 cm, the standard adult BMI band of 18.5 to 24.9 maps to a healthy-weight range of 56.7-76.3 kg.
- Height used
- 1.750 m
- Healthy range (kg)
- 56.7-76.3 kg
- Healthy range (lb)
- 125.0-168.2 lb
- BMI band used
- 18.5 to 24.9
Step-by-step solution
- 1.Convert height to meters and square it: 1.750 x 1.750 = 3.0625.
- 2.Multiply the squared height by the BMI floor and ceiling: 18.5 and 24.9.
- 3.Read the resulting healthy range as 56.7-76.3 kg or 125.0-168.2 lb.
Walkthrough
Visual walkthrough
Healthy-weight range calculators reverse the BMI equation so a fixed height can be turned into a lower and upper body-weight band.
01
Square the height
1.750^2 = 3.0625
BMI scales weight against height squared, so that same height factor is used for both ends of the range.
02
Apply the BMI boundaries
18.5 to 24.9
The lower bound uses BMI 18.5 and the upper bound uses BMI 24.9, the usual adult healthy-weight reference interval.
03
Read the target band
Both metric and imperial views are shown so the result can be checked against the units you track.
