fWHR (Facial Width-to-Height Ratio) Calculator
Our ai fWHR calculator take bizygomatic width (measured in mm or inches), and upper facial height, then divides width by height to accurately compute fWHR.
For example, if someone’s bizygomatic width measures 145mm and their upper facial height is 75mm, their fWHR calculation would yield 1.93 (145/75 = 1.93), indicating a relatively wider facial structure.
fWHR Chart
| Type | fWHR Range | Description | Example Calculation |
|---|---|---|---|
| Narrow Face | 1.5 – 1.7 | Narrow facial structure | Width: 130mm, Height: 85mm → fWHR = 130 ÷ 85 = 1.53 |
| Average Face | 1.8 – 2.0 | Balanced width and height | Width: 150mm, Height: 80mm → fWHR = 150 ÷ 80 = 1.88 |
| Wide Face | 2.1 – 2.3 | Wider than average face | Width: 170mm, Height: 75mm → fWHR = 170 ÷ 75 = 2.27 |
| Extremely Wide | 2.4 and above | Extremely broad facial width | Width: 200mm, Height: 80mm → fWHR = 200 ÷ 80 = 2.50 |
fWHR Formula
The equation for determining facial width-to-height ratio follows:
fWHR = Bizygomatic Width / Upper Facial HeightExample Calculation
- Bizygomatic Width: 138mm
- Upper Facial Height: 78mm
- Final Ratio: 138/78 = 1.77
This measurement protocol ensures consistent results across different facial assessments and research studies.
How to Calculate Facial Ratio?
- Measure Bizygomatic Width:
- Identify the prominent cheekbone points
- Calculate the horizontal span
- Maintain parallel alignment
- Measure Upper Facial Height:
- Locate the midpoint of upper lip
- Find the highest point of mid-brow
- Measure the vertical distance
- Compute Final Ratio:
- Apply the division formula
Practical Example:
Bizygomatic width = 140mm Upper facial height = 80mm Final fWHR = 140/80 = 1.75Different Facial Ratios

What is fWHR?
The facial width-to-height ratio is biometric measurement in modern research. This anthropometric indicator reflects facial development patterns influenced by hormonal factors and genetic expression. Scientific studies have explored connections between fWHR measurements and various behavioral traits.
