What is ideal body weight?

Ideal body weight is an estimated healthy weight range based on your height, gender, and body composition.

It is not an exact number, but a scientifically based guideline used in medical and fitness contexts.

💡 This calculator gives a realistic healthy range instead of a single misleading number.

How ideal weight is calculated

We use the Devine formula, a widely used medical equation, to estimate your ideal body weight based on height and gender.

📏

Height-based

Your height is the main factor in calculating healthy weight.

⚖️

Gender adjusted

Men and women have different body composition averages.

📊

Range based

We show a healthy range, not a single unrealistic number.

Medical formula used

Male formula (Devine):

50 + 2.3 × (height_in_inches − 60)

Female formula (Devine):

45.5 + 2.3 × (height_in_inches − 60)

This formula is widely used in medical dosing and clinical nutrition to estimate healthy body weight ranges.

Note: This is an estimate. Muscle mass, bone structure, and body fat can significantly affect your real ideal weight.

What is a healthy weight for my height?

Your ideal weight depends on more than height alone, including muscle mass and body composition.

That’s why a range is more accurate than a single number.
