Wondering what a healthy weight looks like for your height? Our ideal weight calculator gives you an instant estimate using trusted medical formulas, no guesswork, no sign-up. We built it to help you set realistic, personalised goals rather than chase a random number.
How We Calculate Your Healthy Weight Range
We run your height, age, and gender through four well-established formulas, Devine, Robinson, Miller, and Hamwi, plus the WHO’s healthy BMI range. Comparing them side by side gives you a fuller picture than any single number can.
Formula | Best For |
Devine | Most widely used clinically |
Robinson | Refined estimate for adults |
Miller | Conservative range |
Hamwi | Quick, simple calculation |
BMI Range (18.5–25) | Broad healthy weight band |
Why One Formula Isn’t Enough
No single formula fits every body. That’s why we show you results from multiple methods together, so you get a realistic weight range instead of one rigid target that ignores your frame and build.
Factors That Shape Your Ideal Body Weight
Your ideal weight isn’t just about height. Age, gender, and body frame size all play a role, muscle mass, bone density, and metabolism shift over the years, and two people of the same height can healthily land at different weights.
We factor these variables in so your result feels personal, not generic. If you’re also curious about how your frame relates to your metabolism, our BMR calculator can show how many calories your body burns at rest, adding useful context to your number.
It’s A Range, Not A Rule
Think of your result as a healthy weight window, not a strict target. Athletes and highly muscular individuals often sit outside standard ranges while remaining perfectly healthy; that’s a limitation worth keeping in mind.
Pair It With Your BMI And Body Composition
An ideal weight number means more alongside other markers. Check your BMI calculator result for a quick health-range snapshot, or use our body fat calculator to see how much of your weight is lean mass versus fat, a fuller view than weight alone can offer.
We always recommend reading your ideal weight result together with these other metrics rather than in isolation.
Turn Your Result Into A Plan With Free Ideal Weight Calculator
Once you know your target range, the next step is action. Our TDEE calculator helps you figure out your daily calorie needs to reach it, while our macro calculator breaks that down into protein, carbs, and fat.
We designed these tools to work together, so you’re never left with a number and no next step.
Frequently Asked Questions
What is a good ideal weight for my height?
A good ideal weight range comes from averaging the Devine, Robinson, Miller, and Hamwi formulas for a given height and gender. The calculator above returns that exact range in seconds.
Is BMI the same as ideal weight?
No. BMI divides current weight by height squared. Ideal weight formulas calculate a target range from height and gender alone, without using current weight at all.
Does ideal weight change with age?
Rarely, past the growth years. Height stops increasing around 15 for girls and 17 for boys, and ideal weight formulas depend entirely on height after that point.
How accurate are ideal weight formulas?
They give a solid general estimate, not a lab-grade number. Body frame size, muscle mass, and fat distribution all shift the real healthy number for any one person.
Is ideal weight different for men and women?
Yes. Every formula above uses a lower starting kilogram value and a different per-inch increment for women compared to men, even at the exact same height
