About Weight For Height Chart Calculator

A weight-for-height chart is just the healthy BMI band converted back into kilograms: multiply 18.5 and 24.9 by height in metres squared. At 1.70 m that gives 53.5 to 72.0 kg, so 78 kg sits about 6 kg above the range. The band is deliberately wide because healthy weight depends on build as well as height.

Formulas

Healthy weight range

weight = BMI x height(m)^2, for BMI 18.5 to 24.9

Current BMI

BMI = weight / height(m)^2

Worked example

With the default values below, Weight For Height Chart Calculator returns Bottom Of The Healthy Range of 53.5. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • These figures are population-average estimates, not a medical assessment or diagnosis. Body composition equations carry errors of several percentage points, and healthy ranges vary with age, ethnicity, muscularity and medical history. Discuss weight or body composition goals with a qualified clinician or dietitian.
  • This is an estimate for general information and not professional medical advice. See the full disclaimer for the limits that apply to this kind of calculator.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Why is the range so wide?

Because a 6.4 point BMI span covers real variation in muscle mass and frame. Being at either end can be perfectly healthy.

Do athletes fit these charts?

Often not. Muscular athletes routinely exceed the top of the range with low body fat, which is a limitation of the BMI band rather than a health problem.
