Ideal Weight Calculator
Ideal Weight Calculator
Explore a height-based adult BMI reference range and a separate historical Devine formula estimate. Neither is a personalized ideal weight.
Important: A single “ideal weight” cannot be determined from height alone. BMI does not measure body fat distribution, muscle mass or individual health. Devine was developed for historical clinical dosing calculations and should not be used here to set medication doses. CDC adult BMI · NICE thresholds · Devine formula context.
Ideal Weight Calculator FAQs
1. What is an Ideal Weight Calculator?
An Ideal Weight Calculator estimates a reference weight range based on your height and established adult BMI categories. Some calculators also use formulas such as Devine, which considers height and a sex-based coefficient. These results are estimates, not a personalized ideal weight or a diagnosis of health.
2. What is the ideal weight for a 170 cm male?
For an adult male who is 170 cm tall, the standard BMI-based healthy weight range is approximately 53.5–72.3 kg. The Devine formula gives a separate clinical reference estimate of about 65.9 kg. Neither result identifies a single perfect weight, as body composition and individual health factors also matter.
3. What is the ideal weight for a 160 cm female?
For an adult female who is 160 cm tall, the standard BMI-based healthy weight range is approximately 47.4–64.0 kg. This range is calculated using BMI values from 18.5 to below 25. The actual weight appropriate for an individual may differ depending on muscle mass, health conditions and other factors.
4. Why does sex matter in some ideal weight calculations?
Standard adult BMI-based weight ranges depend on height and do not use sex. However, formulas such as Devine use different male and female coefficients. These formulas provide mathematical reference estimates and should not be interpreted as exact personal weight targets.
5. Are ideal weight ranges different for Indian and South Asian adults?
Some guidelines recommend lower BMI thresholds for South Asian adults because certain cardiometabolic risks can occur at lower BMI levels. NICE uses a BMI of 23 to below 27.5 for overweight and 27.5 or above for obesity in these populations. The calculator’s lower-threshold option provides additional context, not a personalized weight prescription.
6. Is the Devine formula the same as a healthy BMI weight range?
No. The Devine formula produces a single clinical reference weight estimate and has historically been used in medication-dosing calculations. A BMI-based range calculates weights corresponding to selected BMI boundaries. Neither method directly measures body fat or determines an individual’s optimal weight.
7. Is ideal weight the same for everyone, and how accurate is the calculator?
No. People of the same height can have different muscle mass, body composition and health needs. An Ideal Weight Calculator is a general screening and educational tool rather than an exact measurement of healthy body weight. Its adult estimates should not be used as standard targets for children, teenagers or during pregnancy. A healthcare professional can provide more individualized guidance when needed.
