Inputs

Units cm/kg or ft/lbs
Model / Sex (for formulas) for "no input" averaged
Height in cm
Age Years

Results

Consensus Range (from multiple formulas)

Body Frame: —
Tip: Use the consensus range as a target corridor. A single number is rarely "perfect" – ranges are more practical.

BMI & Healthy Weight Range (BMI 18.5–24.9)

BMI Status: —
UnderNormalOverObesity
Note: BMI is a rough guideline. With high muscle mass, it can appear "too high" even if body fat percentage is low.

Understanding Ideal Weight: More than a Number

The term "Ideal Weight" sounds like a perfect target number – in practice, it is rather a useful orientation value. A good Ideal Weight Calculator therefore provides you not just with a single number, but a range. That's exactly what this Online Ideal Weight Calculator does: It calculates your ideal weight using several known methods (e.g., Devine, Robinson, Miller, Hamwi, Lorentz, Broca, and Creff) and shows a Consensus Range. This allows you to realistically assess which weight fits your height – without getting stuck on a number.

Why are there multiple ideal weight formulas?

Many formulas were originally developed to determine rough reference values. They mainly use height and a sex-related model because these data are readily available. At the same time, people differ greatly: Muscle mass, fat distribution, bone structure, and training status vary. Therefore, different approaches lead to slightly different results. Comparison is helpful: If several methods land in a similar area, that is usually a stable frame of reference.

Ideal Weight, Normal Weight, and BMI – what is the difference?

The Body Mass Index (BMI) relates weight and height (kg/m²). It describes a range that is statistically often associated with a lower health risk. This calculator complements the classic BMI Calculator by additionally evaluating multiple ideal weight formulas and outputting the healthy BMI range (18.5–24.9) as a weight range. Important: An athletic person can have significantly less body fat at the same BMI as someone with little muscle – BMI and ideal weight are therefore orientation, not absolute truth.

Body Frame & Wrist: A Plus in Individuality

Common question: "I have a broad bone structure – does the ideal weight fit then?" That's why the calculator offers a Body Frame Option. If you enter your wrist circumference, it can automatically roughly classify the frame structure (slim/normal/broad). This mainly flows into the Creff Formula. For athletes, however: Circumference measurements, body fat estimates, or performance values can be more meaningful than any standard formula.

How to use the Ideal Weight Calculator optimally

  • Choose the units (cm/kg or ft/lbs) and enter your height.
  • Optional: Enter your current weight – then you see BMI, classification, and the difference to the target range.
  • Age and (optional) wrist help to interpret the results better.
  • Set a Target BMI (e.g., 22 as "middle" of the normal range) and get a concrete target weight.

How accurate is the result?

Ideal weight is not a medical limit, but an approximation. Factors like pregnancy, growth, illnesses, medication, or exceptionally high muscle mass are not fully reflected. Use the values as a starting point and focus on sustainable habits: regular exercise (strength + endurance), sufficient protein, plenty of vegetables/fiber-rich foods, sleep, and stress management. If you have health conditions or want to lose/gain weight significantly, professional guidance (doctor or nutritional counseling) is sensible.

FAQ about Calculating Ideal Weight

What is a "healthy weight"?
A healthy weight usually lies in a range, not at a single number. The calculator therefore shows both a consensus range from multiple formulas and the weight range that fits BMI 18.5–24.9. Both are orientation aids, not a diagnosis.
Which ideal weight formula is the best?
There is no single best formula. Devine, Robinson, Miller, and Hamwi often provide similar results and are widely used. Lorentz and Broca are simpler, while Creff additionally considers age and body frame. Most useful is usually the comparison and the derived consensus.
Why does ideal weight differ by sex?
Many formulas use different starting values because average body composition and fat distribution differ. This is a statistical approximation. If you choose "no input", the calculator averages male and female reference values and shows you a more neutral orientation range.
Is BMI meaningful for athletes?
With high muscle mass, BMI can appear "too high" even though body fat percentage is low. In such cases, waist-to-height ratio (WHtR), circumference measurements, or body fat measurements are often more helpful. Use the calculator primarily for the formula comparison then.
Can I use the calculator for children or teenagers?
For children and teenagers, age- and sex-specific percentiles apply instead of adult BMI limits. This ideal weight calculator is therefore intended for adults. For young people, pediatric reference values and medical assessment are better suited.
How fast should one lose or gain weight?
Sustainable changes are usually better than crash diets. Often a moderate pace is recommended (e.g., a few hundred grams per week), adapted to starting situation, health, and daily life. In case of illnesses or extreme starting values, professional guidance is important.
How do I reach my target weight sustainably?
Rely on routines instead of perfection: more daily movement, 2–3 strength training sessions per week, sufficient protein, a good portion of vegetables per meal and a realistic calorie goal. Small steps that you actually maintain lead to the healthy target range in the long run.
