Perfect for fitness goal setting, weight loss targets, and health assessments. Includes BMI-based recommendations and ideal weight ranges.
We only need your height to show the ideal range. Add your weight to see where you stand.

How the range is derived
BMI is a screening tool, not a diagnosis.
What is Ideal Weight?
A healthy range based on height, not a single number
Ideal weight is a healthy range, not a single number. It balances your height, body structure, and how you feel day to day. Most screening tools use the BMI healthy band (18.5–24.9) to outline this range.
Different bodies distribute weight differently. The range simply frames where health risks tend to be lower for most adults.
How is Ideal Weight Calculated?
BMI-based formula with multiple comparison methods
We map the accepted BMI range of 18.5–24.9 onto your height. Height can be in centimeters or feet+inches, and the result can be shown in kilograms or pounds.
Advanced tabs also show Devine, Hamwi, Robinson, and Miller formulas so you can compare common methods alongside BMI.

Ideal Weight vs BMI
How ideal weight relates to the BMI healthy band
Ideal weight converts BMI's healthy band into kilograms or pounds. BMI is quick to compute and works well at population level, but it does not account for muscle, bone density, or fat distribution.
- Ideal weight is a range framed by BMI.
- Use it as a starting point; body composition adds nuance.
- Metric and imperial units both supported for clarity.
Ideal Weight Limitations
Important caveats about muscle, age, and ethnicity
Useful guardrails, but not medical advice:
- •Muscle vs fat: athletes can appear “over” despite healthy body fat.
- •Elderly: lower muscle mass can distort the picture.
- •Ethnic variation: health risks can shift at the same BMI.
- •Frame size and body composition add context.
Treat the range as a gentle guide. For medical questions, consult a professional who can factor in labs, history, and goals.
