Determining your ideal weight is an important step in maintaining good health. While there's no single "perfect" weight, various formulas and methods can help you establish a healthy weight range based on your height. This guide explains how to calculate ideal weight using different approaches and provides a practical calculator to help you estimate your target weight.

What is ideal weight?

Ideal weight refers to the weight range that is generally considered healthy for a person of a particular height. It's important to note that ideal weight is not the same as "perfect" weight, as individual body composition and health factors can vary significantly.

The concept of ideal weight is based on statistical averages and general health guidelines. It's a useful reference point, but it shouldn't be the sole determinant of whether you're healthy. Other factors like muscle mass, body fat percentage, and overall health should also be considered.

Remember that weight is just one measure of health. Focus on overall well-being, including diet, exercise, and lifestyle habits.

How to calculate ideal weight

There are several methods to calculate ideal weight, each with its own formula and assumptions. The most common approaches include:

  1. Using height-based formulas
  2. Body Mass Index (BMI) ranges
  3. Waist-to-height ratios
  4. Waist-to-hip ratios

Each method has its own advantages and limitations. The calculator on this page uses the most common height-based formulas to provide you with a range of possible ideal weights.

Common formulas for calculating ideal weight

Several formulas are commonly used to estimate ideal weight based on height. Here are three of the most popular methods:

Hamwi Formula

For men: Ideal weight = 48 kg + 1.1 kg per inch over 5 feet

For women: Ideal weight = 45.5 kg + 0.9 kg per inch over 5 feet

Men: Ideal Weight = 48 + 1.1 × (Height in inches - 60) Women: Ideal Weight = 45.5 + 0.9 × (Height in inches - 60)

Devine Formula

For men: Ideal weight = 50 kg + 2.3 kg per inch over 5 feet

For women: Ideal weight = 45.5 kg + 2.3 kg per inch over 5 feet

Men: Ideal Weight = 50 + 2.3 × (Height in inches - 60) Women: Ideal Weight = 45.5 + 2.3 × (Height in inches - 60)

Robinson Formula

For men: Ideal weight = 52 kg + 1.9 kg per inch over 5 feet

For women: Ideal weight = 49 kg + 1.7 kg per inch over 5 feet

Men: Ideal Weight = 52 + 1.9 × (Height in inches - 60) Women: Ideal Weight = 49 + 1.7 × (Height in inches - 60)

These formulas provide different estimates of ideal weight based on height. The calculator on this page uses all three formulas to give you a range of possible ideal weights.

Worked example

Let's calculate the ideal weight for a 68-inch tall (5'8") woman using all three formulas:

Formula Calculation Result (kg)
Hamwi 45.5 + 0.9 × (68 - 60) = 45.5 + 7.2 = 52.7 52.7 kg
Devine 45.5 + 2.3 × (68 - 60) = 45.5 + 16.1 = 61.6 61.6 kg
Robinson 49 + 1.7 × (68 - 60) = 49 + 11.9 = 60.9 60.9 kg

For a 68-inch tall woman, the three formulas suggest ideal weights ranging from 52.7 kg to 61.6 kg. The actual ideal weight may vary based on individual factors.

FAQ

Which formula is the most accurate for calculating ideal weight?
There is no single "most accurate" formula. Different formulas provide different estimates based on different assumptions. The best approach is to use multiple formulas and consider your individual health factors.
Can I use these formulas to determine if I'm overweight?
While these formulas can provide a general estimate of ideal weight, they shouldn't be the sole determinant of whether you're overweight. Other factors like body composition, muscle mass, and overall health should also be considered.
Are these formulas the same as BMI?
No, these formulas are different from BMI. BMI calculates body mass index based on height and weight, while these formulas estimate ideal weight based solely on height. Both have their uses but measure different aspects of health.
Can I use these formulas for children?
These formulas are generally designed for adults. For children, different growth charts and pediatric standards are typically used to assess healthy weight development.
