Reviewed by Calculator Editorial Team

Determining your ideal weight based on height and age is an important step in maintaining a healthy lifestyle. This calculator provides an accurate estimate using established formulas that account for both physical measurements and age-related factors.

How to Use This Calculator

Using our ideal weight calculator is simple:

  1. Enter your height in feet and inches or centimeters
  2. Enter your age in years
  3. Select your gender (optional for more accurate results)
  4. Click "Calculate" to see your ideal weight range

The calculator will display your ideal weight in pounds along with a recommended range based on standard health guidelines.

The Formula Explained

Our calculator uses a modified version of the Hamwi formula, which is commonly used for estimating ideal body weight:

For males: Ideal Weight (lbs) = 4.54 × (Height in inches - 152.4) + 106.3

For females: Ideal Weight (lbs) = 4.35 × (Height in inches - 144.3) + 91.4

Age is factored into the result by adjusting the weight range by ±5% for every 10 years from age 25.

This formula provides a more accurate estimate than simple height-based calculations by accounting for gender differences and age-related changes in body composition.

Interpreting Your Results

Your ideal weight range is calculated based on:

  • Your height in inches
  • Your age in years
  • Your gender (if provided)

The result shows a recommended weight range rather than a single number because:

  1. Individual body composition varies
  2. Muscle mass differs between people
  3. Age-related changes affect weight distribution

Note: This calculator provides an estimate only. Consult with a healthcare professional for personalized advice about your weight and health.

Worked Example

Let's calculate the ideal weight for a 5'7" (71 inches) 30-year-old male:

  1. Using the male formula: 4.54 × (71 - 152.4) + 106.3 = 147.5 lbs
  2. Age adjustment: Since 30 is within 5 years of 25, no adjustment is needed
  3. Final result: 147.5 lbs ± 5% = 139.9 to 155.1 lbs

This means a healthy weight range for this individual would be between 140 and 155 pounds.

Frequently Asked Questions

Is this formula accurate for everyone?
The formula provides a general estimate. Individual variations in body composition may affect the actual ideal weight. For precise medical advice, consult a healthcare professional.
Why does age matter in weight calculation?
As people age, muscle mass tends to decrease while fat mass may increase. This affects the relationship between height and weight, which is accounted for in our formula.
Can I use this for children?
This calculator is designed for adults. For children, specialized growth charts should be used that account for developmental stages and growth patterns.
What if I'm very muscular?
Muscle weighs more than fat, so the calculator may underestimate your ideal weight. Bodybuilders and athletes often need to adjust the results based on their specific goals.
How often should I recalculate my ideal weight?
You can use this calculator whenever you need a reference point, but it's most useful when you're making significant changes to your diet or exercise routine.
