How to Know the Ideal Weight for your Age and Height

There are many ways you can discover the ideal weight for your age and height. Here are some of the common and recommended methods:

Body Mass Index (BMI)

A tool that measures your weight in relation to your height, and usually returns a single number. Below is a summary ofthe various categories of BMI result.

  • BMI less than 18.5 = Underweight.
  • BMI between 18.5 and 24.9 = Ideal weight.
  • BMI between 25 and 29.9 = Overweight.
  • BMI over 30 = Obesity.

Waist-to-Hip Ratio (WHR)

Here, your waist size is compared with that of your hip.

To calculate your WHR, take a measurement of the narrowest part of your waist, usually a bit above the belly button. Also measure the width of your hip at the widest part. Then divide the first result (narrowest hip part) by the second result (widest hip part).

A high WHR implies that you have higher levels of visceral fat (the fat that surrounds several major organs in the abdominal cavity). A person with a high WHR has a higher risk of developing Cardio Vascular Diseases (CVD), heart attack and type 2 diabetes.

Below are the average values for WHRs and their health risk level for both male and female:

  • Low Health Risk: Below 0.9, for males. Below 0.8, for females.
  • Moderate Health Risk: Between 0.9 and 0.99, for males. Between 0.8 and 0.89, for females.
  • High Health Risk: Over 1.0, for males. Over 0.9, for females.

Waist-to-Height Ratio (WtHR)

Here, your weight is calculated by comparing your waist size to your height.

To calculate your WtHR, measure your waist size. Also measure your height. Then divide your waist size by your height size. You have a moderate weight if your WHR is not above 0.5.

A person with high WtHR (above 0.5) has a higher risk of diabetes, heart disease and overall mortality.

Body Fat Percentage

To calculate your body fat percentage, divide the weight of your body fat (includes both essential and stored fat) by your total body weight.

The most common way to measure body fat percentage is to use a skinfold measurement, in which special calipers are used to pinch the skin. The tissues on the chest for males or upper arms for females, abdomen and thigh are measured by a health professional.

There are other ways of measuring the body fat percentage, which include:

  • Dual-energy x-ray absorptiometry
  • Hydro-static body fat measurement
  • Bio-electrical impedance analysis
  • Air densitometry method, etc.

Calculating your body fat percentage is one of the recommended ways to estimate your body fitness level because it reflects your body composition.

Although everybody needs essential fat to survive, it becomes a health risk when it in excess in your body. Excessive fat proportion in the body is linked to high risk of high blood pressure, diabetes, stroke and heart disease.
