Calculate your ideal weight at home with simple tools and formulas
What is Ideal Weight?
Ideal weight is the healthy range of weight that is considered normal for a person's height, age, and gender. Unlike BMI, which is a general measure of body mass, ideal weight calculators use specific formulas to estimate the most suitable weight for you.
According to the World Health Organization (WHO), maintaining an ideal weight reduces the risk of heart disease, diabetes, and other lifestyle-related illnesses.
Why Calculate Ideal Weight at Home?
You should calculate your ideal weight at home because:
- It sets realistic fitness goals.
- It helps avoid being underweight or overweight.
- It prevents health issues caused by poor weight management.
- It is quick, free, and accurate using online tools.
The CDC recommends calculating weight based on age, height, and body structure to achieve better health outcomes.
Tools to Calculate Ideal Weight at Home
To calculate your ideal weight, you need:
- Accurate height measurement.
- Gender and age information.
- Access to formulas like Devine or Robinson.
- Free online calculators such as the Nutrifitcalc Ideal Weight Calculator.
Ideal Weight Calculator Formulas
There are several formulas used by experts to estimate ideal weight.
Devine Formula
Male: 50 kg + 2.3 kg per inch over 5 ft.
Female: 45.5 kg + 2.3 kg per inch over 5 ft.
Robinson Formula
Male: 52 kg + 1.9 kg per inch over 5 ft.
Female: 49 kg + 1.7 kg per inch over 5 ft.
Hamwi Formula
Male: 48.0 kg + 2.7 kg per inch over 5 ft.
Female: 45.5 kg + 2.2 kg per inch over 5 ft.
Example (Male, 175 cm):
- Height = 175 cm (5 ft 9 in) → 9 in over 5 ft.
- Devine Formula = 50 + (2.3 × 9) = 70.7 kg
Example (Female, 165 cm):
- Height = 165 cm (5 ft 5 in) → 5 in over 5 ft.
- Devine Formula = 45.5 + (2.3 × 5) = 57 kg
The NIH confirms these formulas are standard for clinical weight assessments.
