How to Use the Healthy Weight Range Calculator

Enter your height and this tool calculates the healthy weight range for that height, based on the standard BMI (Body Mass Index) range of 18.5-24.9 that health organizations classify as "normal weight." Instead of giving a single target number, it shows the full span of weights that fall inside the healthy BMI band for your exact height.

Min Weight (kg) = 18.5 × Height(m)²   |   Max Weight (kg) = 24.9 × Height(m)²

Example

A person who is 170 cm (1.70 m) tall has a healthy weight range of 18.5 × 1.70² = 53.5 kg up to 24.9 × 1.70² = 72.0 kg — roughly 118 lb to 159 lb. Any weight within that range corresponds to a BMI between 18.5 and 24.9.

Common Use Cases

  • Getting a realistic target weight range to aim for, rather than a single rigid number.
  • Checking whether a current or goal weight falls within the standard healthy BMI band.
  • Setting a sensible weight-loss or weight-gain target range with a doctor or trainer.

FAQs

  • How is this different from the Ideal Weight Calculator? The Ideal Weight Calculator uses clinical single-point formulas — Devine, Robinson, and Miller — that each output one specific number based on height and gender, originally developed for medication dosing. This Healthy Weight Range Calculator instead uses the standard BMI classification bands (18.5-24.9 = normal weight) to show a full RANGE of healthy weights for a given height, without factoring in gender at all. They're two different, independently valid methods, and it's normal for their numbers not to match exactly.
  • Why is there a range instead of one target number? Healthy body weight naturally varies by frame size, muscle mass, and build — a single number can't capture that. The BMI-based range gives a wider, more forgiving target band that reflects the reality that many different weights are considered healthy for the same height.
  • Does this account for muscle mass or body composition? No — like all BMI-based methods, this calculator only uses height, so it can't distinguish muscle from fat. A muscular, athletic person may fall above this range while still being lean and healthy, and BMI-based ranges should be treated as a general population guideline rather than a precise individual assessment.
