You've measured your face length and the ruler reads 18 centimeters. Now you're wondering: Is my face small? Is it average? In the world of facial aesthetics, numbers can be deceiving without context. Let's break down what 18 cm really means scientifically.
The Verdict: Is 18 cm Small?
Quick Answer
No, 18 cm is not a small face. Statistically, 18-19 cm is considered the global average face length for adult women and lies just below the average for adult men.
Face size is relative. An 18 cm face might look "small" on a person who is 6'4" (193 cm) tall, but "long" on someone who is 5'2" (157 cm). It's all about proportionality to your body frame.
Global Average Face Sizes
To understand where you fit in, let's look at the scientific data regarding morphological face height (measured from the nasion/root of nose to the gnathion/chin) and physiognomic face height (hairline to chin).
| Gender | Average Length (Hairline to Chin) | Classification of 18 cm |
|---|---|---|
| Female | 17.0 cm - 18.5 cm | Average to Slightly Long |
| Male | 18.5 cm - 20.0 cm | Slightly Small / Compact |
How to Measure Correctly
Many people get "small face anxiety" simply because they measure incorrectly.
The Standard Method
- Find your Trichion (the midpoint of your hairline). If you have a receding hairline, estimate where it naturally started.
- Find your Menton (the lowest point of your chin).
- Measure the straight vertical distance between these two points.
Tip: Use a rigid ruler, not a flexible tape measure aimed over your nose, which adds length.
Why Width Matters More Than Length
A raw number like "18 cm" tells you nothing about your face shape. The crucial metric is your Facial Index (Length divided by Width).
- 18 cm Length + 12 cm Width: You likely have an Oblong or Oval shape. Your face will appear long and elegant.
- 18 cm Length + 16 cm Width: You likely have a Round or Square shape. Your face will appear compact and strong.
