Understanding Your Healthy Weight Range

Rather than a single target number, this calculator gives you a range — every weight between the low and high end of the WHO healthy BMI band (18.5-25) is considered a healthy weight for your height.

Height-Based Only

This range depends only on height — it doesn't factor in age, sex, or frame size, which is why it's presented as a range rather than a single number.

A Range, Not a Target

Any weight within the range is considered healthy by BMI standards — there's no need to aim for the exact midpoint.

Complements Formula-Based Tools

Use this alongside our Ideal Weight Calculator for a formula-based single number, or our BMI Calculator to see where your current weight falls.

Same BMI Blind Spots

Because it's BMI-derived, this range shares BMI's limitations — it can't distinguish muscle mass from fat mass.

How the Range Is Calculated

\[ \text{Weight Range} = 18.5 \times h^2 \; \text{to} \; 25 \times h^2 \]

Where h is height in meters. This is simply the BMI formula solved for weight at the two boundaries of the WHO healthy BMI range.

Important Limitations

No age or sex adjustment: Unlike formula-based ideal weight calculators, this range is purely height-derived.
Doesn't account for muscle mass: Very muscular individuals may fall outside this range while being perfectly healthy.
A screening tool, not a diagnosis: Like BMI itself, this range is a population-level guideline, not an individual health verdict.

Key Takeaways

It's a range, not a number. Any weight within the healthy BMI band is a reasonable target.
Height is the only input. This makes it simple, but also means it can't personalize for body composition.
Pair it with other tools. Combine with BMI or body fat percentage for a fuller picture.
Consult a professional. This range is a population-level guideline — your doctor can help set a personal target that accounts for muscle mass, frame size, and health history.
