Yes, ear size can increase, primarily in length, as people age.
How Does Ear Size Change Over Time?
Research indicates that our ears don't just stop growing when we reach adulthood. Instead, they continue to elongate, albeit very slowly.
Ear Length Growth
A study examined ear length changes in adults between 30 and 93 years old. The results demonstrated a consistent increase in ear length with age [1].
- Average Growth Rate: The study calculated that, on average, ear length increases by approximately 0.22 mm per year [1].
- Consistent Growth: This growth appears to occur consistently throughout adulthood, not just during specific periods.
- Age Range: The study included both male and female participants, ranging from 30 to 93 years of age.
Factors Influencing Ear Size Increase
While the primary factor is age, it’s helpful to consider that:
- Individual Variation: The study indicated an average increase, meaning that some individuals will experience slightly more or less growth than others.
- No Significant Gender Difference: The study was not specifically focused on gender and didn't report any significant differences between men and women.
Practical Insights
Although the average growth of 0.22 mm per year might seem small, it accumulates over a lifetime, particularly into later adulthood. This means the ears are one of those body parts that continue to grow with time.
