Ideal Weight Formulas

Peterson formula (2016)

(2.2 × target BMI) + (3.5 × target BMI × (height [m] - 1.5))

By default, our calculator uses 21.75 as the target BMI.

This formula is independent of the gender.

Robinson Formula (1983)

  • For men: 52 kg + 1.9 kg per inch over 5 feet
  • For women: 49 kg + 1.7 kg per inch over 5 feet

Miller Formula (1983)

  • For men: 56.2 kg + 1.41 kg per inch over 5 feet
  • For women: 53.1 kg + 1.36 kg per inch over 5 feet

Devine Formula (1974)

  • For men: 50.0 kg + 2.3 kg per inch over 5 feet
  • For women: 45.5 kg + 2.3 kg per inch over 5 feet

Hamwi Formula (1964)

  • For men: 48.0 kg + 2.7 kg per inch over 5 feet
  • For women: 45.5 kg + 2.2 kg per inch over 5 feet

Lorentz Formula (1929)

  • For men: (height [cm] - 100) - (height [cm] - 150)/4
  • For women: (height [cm] - 100) - (height [cm] - 150)/2

Broca Formula (1871)

height [cm] - 100

This formula is independent of the gender.

Calculating Ideal Weight with Examples

Let's calculate the ideal weight for a 30-year-old woman using different formulas:

Height: 5 feet 6 inches (approximately 1.68 meters)

Peterson formula:

(2.2 × target BMI) + (3.5 × target BMI × (height [m] - 1.5)) = (2.2 × 21.75) + (3.5 × 21.75 × (1.68 - 1.5)) ≈ 62 kg

Robinson Formula:

49 kg + 1.7 kg per inch over 5 feet = 49 kg + 1.7 kg × 6 ≈ 59.2 kg

Miller Formula:

53.1 kg + 1.36 kg per inch over 5 feet = 53.1 kg + 1.36 × 6 ≈ 61.2 kg

Hamwi Formula:

45.5 kg + 2.2 kg per inch over 5 feet = 45.5 kg + 2.2 × 6 ≈ 58.7 kg

Devine Formula:

45.5 kg + 2.3 kg per inch over 5 feet = 45.5 kg + 2.3 × 6 ≈ 59.3 kg

Broca Formula:

height [cm] - 100 = 168 cm - 100 = 68 kg

Lorentz Formula:

(height [cm] - 100) - (height [cm] - 150)/2 = (168 cm - 100) - (168 cm - 150)/2 = 68 - 9 = 59 kg

FAQ

✅ What exactly is an "ideal weight?"

n ideal weight refers to a range considered healthiest for your height and body type based on calculations and statistical data. It's meant as a general guideline for weights associated with lower risks of weight-related health issues.

✅ How does the ideal weight calculator work?

Most ideal weight calculators use formulas that factor in your height, age, gender, and sometimes your wrist measurement or body frame size. They then spit out a recommended target weight range that statisticians have determined may reduce your health risks.

✅ Is there one universal ideal weight for everyone?

Not at all! Ideal weight ranges can vary substantially from person to person based on biological sex, age, muscularity, bone density, body type and more. That's why it's an estimate rather than a one-size-fits-all number.

✅ My ideal weight seems too low/high - is the calculator wrong?

It's possible the calculator may overcorrect or undercorrect for your specific body composition and build. These tools are based on broad population data, so individual factors like muscle mass can throw the estimates off. Use your result as one general data point.

✅ I'm muscular - will that affect my ideal weight?

Yes, having higher muscle mass means you'll likely want to aim for the higher end of your ideal range or potentially beyond it. Muscle tissue is denser than fat, so very fit people can be heavier yet still healthy.

✅ Does my frame size matter for ideal weight?

Some ideal weight calculations do account for different body frame sizes - whether you have smaller or larger bone structure and overall build. Having accurate measurements like your wrist circumference can improve the estimate.

✅ Is ideal weight the same as a healthy BMI range?

Not exactly. BMI (body mass index) and ideal weight are similar concepts that consider height and weight, but the calculations differ slightly. BMI has defined thresholds, while ideal weight allows for a range.

✅ I'm pregnant - should I use the ideal weight calculator?

No, most ideal weight calculations won't provide accurate targets if you're expecting. During pregnancy, recommended weight gain guidelines are based on factors like your pre-pregnancy BMI and stage of pregnancy.

✅ My goal is weight loss - will the ideal calculator give me a target?

While calculating your ideal weight can provide a general benchmark, most experts recommend setting more modest initial weight loss goals of 5-10% of your body weight if needed for health reasons.

✅ Does age play a role in ideal weight?

Yes, ideal weight calculations do factor in age to a degree. As we get older, muscle mass tends to decrease while fat mass increases, even if overall weight stays stable. Ideal ranges may shift accordingly.

✅ Is striving for an ideal weight actually...ideal?

Not necessarily! An ideal weight is just one metric that doesn't tell the whole story. Overall health markers like bloodwork, energy levels, and how you feel are also crucial. Don't obsess over hitting a number - focus on sustainable lifestyle habits.

The ideal weight calculator can serve as a helpful reference point as you pursue a healthier lifestyle. But don't get fixated on its results. True "ideal" health requires a holistic look at nutrition, fitness, mental health and so much more beyond just the number on the scale.
