# Ideal Weight Calculator

See a range from the Devine, Robinson, Miller and Hamwi formulas. There is no single ideal weight.

## Input data

- **Formula profile** - type: choice; default: female; options: Female, Male
- **Height (cm)** - type: number; default: 170; min: 120; max: 250; step: 0.1

## How it works

Each formula starts from a reference weight at 5 feet and adds an amount per inch above it.

> This estimate is educational and is not medical advice.

## Quick examples

- **Female, 170 cm** - Formula profile: female, Height (cm): 170
- **Male, 180 cm** - Formula profile: male, Height (cm): 180
- **Female, 160 cm** - Formula profile: female, Height (cm): 160

## Understanding your result

The displayed interval combines four historical height-based formulas. It is a comparison range rather than a personal target and does not reflect body composition or individual health.
