Healthy Weight (Goal) Calculator
See the weight range that corresponds to a healthy BMI for your height, and compare it with your current weight to set a rough goal. This is based on adult BMI categories.
| Height | ftin or cm |
| Current weight | |
| Target BMI | (healthy range 18.5–24.9) |
Result
Your healthy weight range will appear here.
Formulas
- BMI = weight (kg) / height (m)²
- Weight for a given BMI = BMI × height (m)²
- Healthy BMI range (adults): 18.5 to 24.9 (World Health Organization categories)
BMI is a simple screening measure and does not account for muscle mass, body composition, age, sex, or ethnicity. It may not be appropriate for children, teens, pregnant people, or athletes. Healthy weight is individual — use this as a rough guide and talk with a health professional for personal advice.
How it works
This estimates a healthy weight range for your height using Body Mass Index (BMI) categories for adults, and can compare with a goal weight.
Formula
- BMI = weight(kg) / height(m)² (or 703 × lb / in²).
- Common adult “healthy weight” BMI range: 18.5–24.9. Healthy weight range = BMI range × height².
Worked example
At 170 cm, BMI 18.5–24.9 corresponds to about 53.5–72.0 kg.
Assumptions
- BMI is a screening measure and doesn’t account for muscle mass, body composition, age, sex, or health conditions. It may not be appropriate for everyone (including children/teens without age-specific charts, pregnancy, or some athletes).
