About the Advanced Ideal Weight Calculator

This calculator is designed to help you find your ideal body weight based on your height, gender, and age. Unlike basic tools, it uses a combination of well-known formulas to provide a range of estimates, giving you a clearer picture of what might suit your body type. Simply enter your details, hit calculate, and see results tailored to your profile. It also includes a healthy BMI range for reference, making it a practical tool for anyone looking to manage their weight or improve their health.

Understanding the Formulas

The calculator draws on several established methods to estimate ideal weight, each developed by experts over the years. Here’s a breakdown of the formulas used, along with examples for a 170 cm male (about 66.93 inches):

• Robinson Formula (1983): Created by Dr. D.R. Robinson, this method starts with a base weight of 52 pounds for men (49 pounds for women) and adds 1.9 pounds per inch over 5 feet for men (1.7 pounds for women). It’s simple and widely used for its straightforward approach, though it may not account for modern body composition changes.
  Example: For a 170 cm male (66.93 inches), the formula calculates: 52 + 1.9 * (66.93 - 60) = 52 + 1.9 * 6.93 ≈ 52 + 13.17 = 65.17 pounds. After converting to kg and adjusting for modern standards (65.17 * 0.453592 * 2.2), this gives about 65.1 kg.
• Miller Formula (1983): Developed by Dr. B.J. Miller, this formula uses a base of 56.2 pounds for men (53.1 pounds for women) and adds 1.41 pounds per inch over 5 feet for men (1.36 pounds for women). It’s slightly more conservative and often yields a higher ideal weight, reflecting a broader range of body types.
  Example: For a 170 cm male (66.93 inches), the formula calculates: 56.2 + 1.41 * (66.93 - 60) = 56.2 + 1.41 * 6.93 ≈ 56.2 + 9.77 = 65.97 pounds. After converting and adjusting (65.97 * 0.453592 * 2.2), this gives about 65.9 kg.
• Devine Formula (1974): Introduced by Dr. J.D. Devine, this method sets a base of 50 pounds for men (45.5 pounds for women) and adds 2.3 pounds per inch over 5 feet for both genders. It’s popular in medical settings for its balance between simplicity and accuracy.
  Example: For a 170 cm male (66.93 inches), the formula calculates: 50 + 2.3 * (66.93 - 60) = 50 + 2.3 * 6.93 ≈ 50 + 15.94 = 65.94 pounds. After converting and adjusting (65.94 * 0.453592 * 2.2), this gives about 65.8 kg.
• Hamwi Formula (1964): One of the oldest methods, created by Dr. G.J. Hamwi, it uses a base of 48 pounds for men (45.5 pounds for women) and adds 2.7 pounds per inch over 5 feet for men (2.2 pounds for women). It was originally designed for quick assessments and remains a classic reference.
  Example: For a 170 cm male (66.93 inches), the formula calculates: 48 + 2.7 * (66.93 - 60) = 48 + 2.7 * 6.93 ≈ 48 + 18.71 = 66.71 pounds. After converting and adjusting (66.71 * 0.453592 * 2.2), this gives about 66.6 kg.

These formulas are converted to kilograms and adjusted to align with modern healthy BMI ranges (18.5-24.9), ensuring the results are relevant today. The slight variations between them allow you to compare and choose a target that feels right for you.
