Ideal Weight Calculator
Find your healthy target weight based on height, sex, and body frame — using four established medical formulas.
Your Ideal Weight
Where you sit in the healthy range
Weight at key BMI points
Based on WHO healthy BMI range (18.5–24.9). Frame size shifts the target range: small frame BMI 19–23, medium BMI 20–24.9, large BMI 21.5–26. The midpoint of your range is shown as your ideal weight.
How is ideal weight calculated?
This calculator uses the WHO healthy BMI range (18.5–24.9) as its foundation — the most widely validated standard for healthy weight in adults. Rather than a single number, it gives you a range based on your height and frame size.
Body frame size matters: people with larger bone structures naturally carry more weight at a healthy body composition. A large-framed person's ideal range extends slightly higher (BMI up to 26), while a small-framed person's sits lower (BMI 19–23).
No formula gives a perfect answer. Muscle mass, age, and fitness level all affect what a healthy weight looks like for you personally. Use this range as a guide alongside your BMI and body fat percentage.
