Normal adult ear size varies, but studies provide average measurements.
According to Quatela's study, the average adult ear length falls within the range of 55 to 65 mm. Brucker et al10 obtained a mean Total Ear Height (TEH) of 6.30 cm (63 mm) in their morphometric study. The Quatela study further breaks down average ear lengths by sex:
- Males: 62.4 mm
- Females: 58.4 mm
Here's a table summarizing the typical ear sizes:
| Measurement | Size (mm) | Size (cm) |
|---|---|---|
| Average Ear Length (Overall) | 55-65 | 5.5-6.5 |
| Average Male Ear Length | 62.4 | 6.24 |
| Average Female Ear Length | 58.4 | 5.84 |
Therefore, a "normal" adult ear typically measures between approximately 5.5 cm and 6.5 cm in length, with slight variations between males and females.
