Macrotia refers to the excessive enlargement of the external ear, affecting both its vertical height and width. On average, the vertical height of a female ear is 5.9 cm, and for a male ear, it is 6.2 cm. Ears measuring over 6.5 cm may appear disproportionately large compared to the face and head. Several factors—including age, sex, height, and head size—influence how large or prominent the ears appear. For many people, overly large ears can become a source of concern, drawing unwanted attention and affecting overall facial balance.
