The **FWHR Calculator** (Facial Width to Height Ratio) is designed to measure the ratio between an individual’s facial width and height.

This tool provides a quick way to calculate FWHR for basic measurements or apply adjustment factors in the advanced mode, which can be useful in anthropometric research, psychology, and personal studies

### Input Field Guide

Below is a guide for each input field, including its purpose and an example value for clear understanding:

**Input Field** |
**Purpose and Usage** |
**Example** |

**Facial Width (in)** |
Enter the **Facial Width** in inches. This measurement is from one cheekbone to the other. |
**5.00** |

**Facial Height (in)** |
Input the **Facial Height** in inches, measured from the brow to the upper lip. |
**7.00** |

**Facial Width to Height Ratio (FWHR)** |
This field displays the calculated FWHR, determined by dividing width by height. It’s readonly. |
**Result** |

**Advanced Mode Input Field Guide**

For cases requiring an adjustment factor to modify the facial width and height, the advanced calculator includes additional fields:

**Input Field** |
**Purpose and Usage** |
**Example** |

**Adjusted Facial Width (in)** |
Enter the **Adjusted Facial Width** in inches. This value adjusts the width before calculating the FWHR. |
**5.20** |

**Adjusted Facial Height (in)** |
Provide the **Adjusted Facial Height** in inches. This value adjusts the height before calculating the FWHR. |
**7.30** |

**Adjustment Factor (%)** |
Specify the **Adjustment Factor** in percentage. This percentage modifies both width and height values. |
**10** |

**Adjusted FWHR** |
Displays the calculated adjusted FWHR after applying the adjustment factor to width and height. This field is readonly. |
**Result** |

### Step-by-Step Calculation Examples

The tables below illustrate example calculations in both the basic and advanced modes:

**Basic Calculator Example**

**Step** |
**Calculation** |
**Result** |

**Facial Width (in)** |
**5.00** |
5.00 |

**Facial Height (in)** |
**7.00** |
7.00 |

**FWHR** |
$\frac{5.00}{7.00} = 0.71$ |
**0.71** |

**Advanced Calculator Example**

**Step** |
**Calculation** |
**Result** |

**Adjusted Facial Width (in)** |
**5.00 × (1 + 10/100)** = 5.50 |
5.50 |

**Adjusted Facial Height (in)** |
**7.00 × (1 + 10/100)** = 7.70 |
7.70 |

**Adjusted FWHR** |
$\frac{5.50}{7.70} = 0.71$ |
**0.71** |

Using the **Calculate** button after entering values in the respective fields provides the FWHR. Pressing **Reset** clears all inputs for fresh entries.
