The **waist to height ratio (WHtR) calculator** is a **valuable tool** used to assess an individual’s **body composition** and potential **health risks**.

WHtR is considered by many **health professionals** to be a more accurate predictor of health risks than **Body Mass Index (BMI)**. It takes into account the fact that **abdominal fat**, often referred to as “**visceral fat**,” is more detrimental to health than fat stored in other parts of the body.

## Waist to Height Ratio Calculator

Height (cm) | Waist (cm) | WHtR | Classification | Imperial Conversion |
---|---|---|---|---|

170 | 68 | 0.400 | Healthy | H: 66.9″, W: 26.8″ |

165 | 86 | 0.521 | Overweight | H: 65.0″, W: 33.9″ |

180 | 90 | 0.500 | Overweight | H: 70.9″, W: 35.4″ |

155 | 62 | 0.400 | Healthy | H: 61.0″, W: 24.4″ |

175 | 105 | 0.600 | Obese | H: 68.9″, W: 41.3″ |

**Conversion equation**:

- cm to inches: divide by 2.54
- inches to cm: multiply by 2.54

## Waist to Height Ratio Chart

WHtR Range | Classification |
---|---|

< 0.4 | Underweight |

0.4 – 0.49 | Healthy |

0.5 – 0.59 | Overweight |

≥ 0.6 | Obese |

## Waist to Height Ratio Formula

The formula for calculating WHtR is straightforward:

**WHtR = Waist Circumference / Height**

Both measurements should be in the same unit (typically centimeters or inches).

For instance:

- If an individual has a waist circumference of
32 inchesand a height of70 inches, their WHtR would be: 32 / 70 ≈0.457- Using metric units, if someone has a waist circumference of
80 cmand a height of170 cm, their WHtR would be: 80 / 170 ≈0.471

## What is a healthy waist-to-height ratio?

A

healthy WHtRgenerally falls between0.4 and 0.49. This range is associated with lower risks ofobesity-related health issuessuch ascardiovascular diseases,type 2 diabetes, and certaincancers.

Individuals with a WHtR below **0.4** may be underweight, which can also pose health risks. Those with a ratio of **0.5 or above** are typically categorized as overweight or obese, with increasing health risks as the ratio increases.

### What is the ideal waist to height ratio for women?

For **women**, an ideal WHtR is often considered to be **around 0.42 to 0.48**. This takes into account typical differences in **body composition** between men and women, with women generally having a higher percentage of body fat.

While the healthy range (0.4 – 0.49) applies to both men and women, some research suggests slight variations based on **gender** and **age**.

## How do you calculate waist-to-height?

Calculating your WHtR involves three simple steps:

**Measure your waist circumference**:

- Use a
**flexible tape measure**. - Place it around your bare abdomen, just above your
**hipbones**. - Ensure the tape is snug but not compressing your skin.
- Take the measurement after exhaling normally.

**Measure your height**:

- Stand against a flat surface without shoes.
- Use a
**stadiometer**or mark your height on the wall and measure.

**Divide waist measurement by height**:

- Ensure both measurements are in the same unit (inches or centimeters).
- Use a calculator for precise results.
- For example, if your waist is
**81 cm**and your height is**165 cm**: WHtR = 81 / 165 ≈**0.491**
