Enter your height to see the full weight range considered healthy under the standard 18.5-24.9 BMI band — a range, not a single target number.
This calculator rearranges the standard BMI formula for weight at the two boundaries of the healthy BMI band — 18.5 and 24.9 — giving a minimum and maximum weight for your height: minWeight = 18.5 × height(m)², maxWeight = 24.9 × height(m)². It's the same underlying formula as the BMI Calculator, just solved for weight instead of solving for BMI from a known weight.
No — like BMI itself, this range is based purely on height and doesn't distinguish muscle from fat or account for frame size. A muscular person can sit above this range while carrying genuinely low body fat, and a person with a naturally smaller frame might sit at the low end while still being healthy. See the Body Fat Calculator or Ideal Weight Calculator for measures that go beyond height alone.
No. BMI-based ranges are population-level screening tools, not individualized targets — they don't account for age, sex-specific body composition, muscle mass, or frame size, and were derived from population averages rather than any one person's physiology. Treat this range as a general reference point to discuss with a healthcare professional, not a personal prescription.
The Ideal Weight Calculator uses specific medical formulas (like Devine or Robinson) to produce one single target weight for your height and sex — formulas originally developed for clinical purposes like drug dosing. This tool instead shows the full range of weights considered healthy under the standard BMI band, which is a wider, less prescriptive answer to a related but different question.
Worked example: at 170 cm (1.70 m), minWeight = 18.5 × 1.70² = 18.5 × 2.89 ≈ 53.46 kg, and maxWeight = 24.9 × 2.89 ≈ 71.96 kg — a healthy range of roughly 53.5-72.0 kg (about 117.9-158.7 lb) for that height.
