Looking for a fast, accurate, and globally useful Ideal Weight Calculator (IBW + Healthy Weight Range)? You’re in the right place. This page explains exactly how our Ideal Weight Calculator (IBW + Healthy Weight Range) works, why it’s different, and how you can use it to make informed, health-positive choices. We combine the most widely used IBW equations (Devine, Robinson, Miller, and Hamwi) with a Healthy Weight Range based on BMI so you can see both a single reference number and a practical range for your height — in kg and lb, with instant switching.
Ideal Weight Calculator (IBW) + Healthy Weight Range
Get IBW by Devine, Robinson, Miller, Hamwi and your healthy weight range by BMI — in kg and lb.
This tool is for adults (20–65). Not medical advice.
| Formula | IBW | Alt unit |
|---|---|---|
| Devine | — | — |
| Robinson | — | — |
| Miller | — | — |
| Hamwi | — | — |
For heights < 5′0″, these linear formulas extrapolate; use clinical judgment.
How we calculate
- IBW: Devine, Robinson, Miller, Hamwi (kg), then shown in your chosen unit. Median IBW is the central value across formulas.
- Healthy range: weights mapping to the selected BMI “healthy” band for your height.
Not for children, pregnant people, athletes with very high muscle mass, or adults over ~65 (different targets may apply). For personal advice, consult a clinician.
Quick start: Enter height, select sex, choose output units (kg/lb), pick the BMI scheme (WHO Global or WHO Asian), and hit Calculate. You’ll get IBW by four formulas, a median IBW, and your Healthy Weight Range customized to your population choice.
Why an “Ideal Weight Calculator (IBW + Healthy Weight Range)” still matters today
The concept of “ideal weight” is often misunderstood. People search for a single perfect number, but health is better reflected by ranges and context. Our Ideal Weight Calculator (IBW + Healthy Weight Range) shows:
- Multiple IBW equations: Devine, Robinson, Miller, and Hamwi. You’ll see that the ideal weight for a given height varies a bit depending on the historical equation.
- Median IBW: a balanced, central reference that avoids overreliance on a single formula.
- Healthy Weight Range: a target interval derived from BMI for your height — helpful for real-world planning and goal-setting.
This dual approach is why users, clinicians, and coaches love an Ideal Weight Calculator (IBW + Healthy Weight Range): you get both a research-based reference weight and a flexible range that acknowledges human diversity.
What our Ideal Weight Calculator (IBW + Healthy Weight Range) computes
- IBW (Ideal Body Weight) via four formulas
- Devine (commonly used for medical dosing)
- Robinson
- Miller
- Hamwi
- Median IBW across the four formulas (a sensible center point).
- Healthy Weight Range from BMI bands for your height, in kg or lb, using:
- WHO Global “healthy” band of 18.5–24.9, or
- WHO Asian option using a narrower upper cutoff of 22.9 to reflect different risk profiles in many Asian populations.
Our Ideal Weight Calculator (IBW + Healthy Weight Range) is tuned for adults (approximately 20–65 years). It’s not designed for children, pregnancy, or older adults with special considerations. Highly muscular athletes can also fall outside typical weight-for-height expectations.
How to use the Ideal Weight Calculator (IBW + Healthy Weight Range) effectively
- Enter your height — in cm or ft + in.
- Select sex — several IBW formulas include sex-specific constants.
- Pick output units — kg or lb, switch anytime.
- Choose BMI scheme — WHO Global or WHO Asian (18.5–22.9).
- Tap Calculate — the Ideal Weight Calculator (IBW + Healthy Weight Range) returns all four IBW values, the Median IBW, and the Healthy Weight Range.
Pro tip: Use the Healthy Weight Range to set realistic goals. The Median IBW is a crisp reference, but ranges support day-to-day planning and account for body composition differences.
What each IBW formula represents (in brief)
- Devine (1970s): Very common in hospital and pharmacy settings for medication dosing; built on linear inches over 5 feet.
- Robinson & Miller (1980s): Alternative IBW derivations, often landing a bit higher or lower than Devine.
- Hamwi (1960s): An earlier linear model frequently cited in dietetics.
Because these formulas come from different eras and reference populations, the Ideal Weight Calculator (IBW + Healthy Weight Range) is designed to show them all transparently. The median IBW gives you an immediate, understandable middle number.
When to switch to WHO Asian “Healthy Weight Range”
The WHO Asian option recognizes that some populations show metabolic risks at lower BMI values. If you’re in India, much of South Asia, East Asia, or Southeast Asia, you might select the WHO Asian setting in the Ideal Weight Calculator (IBW + Healthy Weight Range) to see a narrower upper bound (22.9). This helps align your range with regional clinical guidance and public-health practice.
Ideal weight vs. healthy weight: which should you follow?
Use both perspectives:
- IBW is a traditional, height-based reference used in clinical workflows. It’s useful as a single point when one is required (e.g., certain medication calculations in clinical environments).
- Healthy Weight Range (from BMI) is a practical, behavior-friendly range for general health goals. It factors in the idea that any one number is an estimate, not a command.
Our Ideal Weight Calculator (IBW + Healthy Weight Range) brings these together so you don’t have to choose.
Examples: reading your results
Suppose someone 170 cm tall selects WHO Global:
- They might see IBW values around the mid-60s kg (exact numbers vary by formula).
- The Healthy Weight Range might span from roughly the mid-50s to low-70s kg (again, exact numbers depend on the BMI band and your height).
This shows why the Ideal Weight Calculator (IBW + Healthy Weight Range) is helpful: you get a clean IBW reference and a range that reflects normal human variation.
Limitations of IBW and BMI (and what to do instead)
- Not body-fat direct: IBW and BMI cannot differentiate fat vs muscle.
- Athletes & bodybuilders: You may “read high” on BMI but be healthy; consider waist-to-height ratio and clinical evaluation.
- Children/teens: Use age- and sex-specific growth charts instead of adult IBW/BMI.
- Pregnancy: Weight targets follow different guidance; consult your clinician.
- Older adults: Nutritional risk can occur at different cutoffs; seek a personalized plan.
