About this tool
Set a weight goal but not sure which number actually suits your body? This ideal weight and body fat tool shows you the healthy weight range for your height, plus an estimate of your body fat percentage from a few simple tape measurements you can take at home.
It is easy to use. Just enter your sex and height to see your healthy weight range, and if you want a body fat figure too, measure your waist, neck and hips (hip for women) with a tape, then type the numbers in. The tool estimates everything instantly, giving you a full picture from both angles:
- Your ideal weight range shows roughly where your weight should sit
- Your approximate body fat percentage shows how much of your body is fat
When you line these up against your current weight, you can set a realistic goal and plan your eating and exercise more precisely. It works well alongside our BMI and calorie calculators for a well-rounded view of your health.
This tool is free with no sign-up and runs entirely in your browser, so your measurements are never stored or sent anywhere. Keep in mind, though, that the ideal weight and body fat figures are estimates meant to help you set goals, not medical advice. If you want an accurate body composition assessment or have any health concerns, a doctor or nutrition professional can give you the guidance that fits you best.

Frequently asked questions
- What is ideal weight based on?
- It is based mainly on your height and sex, using popular reference formulas. The result is a healthy range rather than a single exact number, since everyone's body frame is different.
- How accurate is body fat from tape measurements?
- The tape-measure method is a convenient way to get a good estimate, though it is not as precise as specialist tools used in clinics. Measure with the tape snug against your body for the closest result.
- Are ideal weight and a healthy weight the same thing?
- They are close, but ideal weight is a formula-based target, while your own healthy weight also depends on your muscle and fat. It is best read alongside your BMI and body fat percentage.
- Is this tool free?
- Yes, it is free with no sign-up. Everything is calculated in your browser and your measurements are never stored.
- Can the results replace advice from a doctor?
- No. The results are an estimate to help you set a goal, not medical advice. For a detailed health assessment, please consult a doctor or qualified professional.
