What is Ideal Weight Calculator?
The Ideal Weight Calculator is a free health tool designed to estimate a person's healthy body weight based on height, gender, and age. Maintaining a healthy weight reduces the risk of serious health conditions such as cardiovascular disease, type 2 diabetes, and high blood pressure. This calculator uses recognized medical equations including the Devine, Robinson, and Miller formulas to provide a realistic target weight range for adults.
Formula
Devine Formula:
Male: 50.0 kg + 2.3 kg per inch over 5 feet
Female: 45.5 kg + 2.3 kg per inch over 5 feet
Benefits of Using Ideal Weight Calculator
Clinical Standards - Uses formulas trusted by doctors and medical professionals.
Personalized Targets - Tailored based on height, gender, and biological parameters.
Health Screening - Helps identify if you are underweight, normal, or overweight.
