About this calculator
This ideal weight calculator uses the Devine formula, widely employed in the medical field to estimate ideal body weight based on height and sex. The formula was originally developed for drug dosage calculations but is now used as a general reference for healthy weight. It considers that the ideal weight for men is 50 kg for the first 152.4 cm of height, adding 2.3 kg for each additional inch. For women, the starting value is 45.5 kg, with the same increment per extra inch.
To use the tool, simply enter your height in centimeters and select your sex. The calculation automatically converts height to inches and applies the Devine formula. The result is displayed in kilograms, rounded to one decimal place. It is important to remember that ideal weight is an estimate and does not consider factors such as body composition, muscle mass, or bone density. Therefore, consult a healthcare professional for an individualized assessment.
This calculator is useful for people who want a quick reference for healthy weight, especially in clinical or nutritional monitoring contexts. It can also be used by healthcare professionals as a starting point for medication dosage calculations. However, it does not replace a complete medical evaluation. Remember that ideal weight varies from person to person, and other methods such as BMI or bioimpedance can provide complementary information.
Cautions: the Devine formula was created for a specific population and may not be accurate for all ethnic groups or for athletes with high muscle mass. Additionally, it does not account for age or body fat distribution. Use the result as a reference, not as an absolute goal. Always prioritize healthy habits and overall well-being over isolated numbers.
Frequently asked questions
Is the ideal weight calculated the same for all ages?
No. The Devine formula does not consider age, so it may not be suitable for children, elderly, or pregnant women. Consult a professional for specific assessment.
Can I use this ideal weight as a weight loss goal?
The result is a reference, not a mandatory goal. Healthy weight depends on many factors. Before setting goals, talk to a nutritionist or doctor.
Does the formula work for athletes or very muscular people?
It is not ideal. The formula does not distinguish muscle from fat, potentially underestimating ideal weight for athletes. Methods like bioimpedance are more accurate.
What is the difference between the Devine formula and BMI?
BMI uses only weight and height, without considering sex. The Devine formula differentiates men and women and is often used clinically for drug dosing.
Why does the calculator ask for sex?
The Devine formula has different starting values for men (50 kg) and women (45.5 kg). Sex directly influences the result.
