What is Ideal Weight Calculator?

The Ideal Weight Calculator compiles the four most widely referenced medical equations used by pharmacologists and clinicians (Devine, Robinson, Miller, and Hamwi) to estimate baseline optimal body mass.

How to Use This Calculator

  1. Choose biological sex.
  2. Specify your height in feet and inches.
  3. Select your wrist skeletal frame size.
  4. Compare medical ideal weights with the WHO healthy BMI corridor.

The Mathematical Formula & Variables

Men: 50 kg + 2.3 kg per inch over 5 ft; Women: 45.5 kg + 2.3 kg per inch over 5 ft

Variables Definition

Symbol / Variable Name Description
Base Height 60 inches (5 feet) Standardized clinical reference height.

Step-by-Step Worked Example

Scenario: Male standing 5 ft 10 in tall (10 inches over 5 ft).

  1. Base weight = 50 kg.
  2. Additional inches: 10 * 2.3 kg = 23 kg.
  3. Ideal weight = 50 + 23 = 73 kg (160.9 lbs).

Result: Ideal Weight = 160.9 lbs

Frequently Asked Questions

Is ideal body weight the same for everyone of the same height?

No. Bone density, muscle development, and genetic frame size account for significant natural healthy variance of +/- 10% to 15%.
