A height weight calculator is an efficient tool that calculates the ideal weight in relation to the height of an individual. This can examine whether a person is underweight, overweight or has a healthy weight, according to their height. Supplementary versions, such as the age and height weight calculator and the height to weight ratio calculator, help determine age-specific and gender-specific body weight, respectively, for both males and females.

Formulas for finding the ideal weight
To find your ideal weight using a height and weight calculator, you can use several formulas:
Body Mass Index (BMI): This common formula calculates weight in relation to height. Ideal BMI ranges from 18.5 to 24.9. Formula: BMI = weight (kg) / height (m²).
Devine formula: Often used for medical dosing, this calculates ideal body weight (IBW). For men: IBW (kg) = 50 + 2.3 x (height (in) - 60). For women: IBW (kg) = 45.5 + 2.3 x (height (in) - 60).
Hamwi formula: Provides a quick estimate of ideal body weight. For men: IBW (kg) = 48 + 2.7 x (height (cm) - 152). For women: IBW (kg) = 45.5 + 2.2 x (height (cm) - 152).
Broca index: A simpler formula, particularly for Europeans. Ideal weight (kg) = height (cm) - 100.
Using a height and weight calculator simplifies these calculations, providing personalised ideal weight recommendations based on your inputs.
How does the height weight calculator work?
A height weight calculator uses different scientific formulas to calculate your ideal weight. Two prominent methods include the Body Mass Index (BMI) and the Hamwi Formulas. The height-weight calculator works by taking into account several factors:
- Height: The primary input, as the ideal weight is directly related to how tall a person is.
- Age: Some calculators factor in age to account for changes in body composition over time.
- Gender: Men and women typically have different body compositions, so gender is an important factor.
- Body frame size: Some calculators include the option to input body frame size to refine the ideal weight range further.
