The Kruckenberg Ear Index


Some time ago we had a dinner discussion that got onto the topic of ear sizes. Heidi made some statement about ears being full size early on, or never stopping growing, or some interesting piece of ear trivia that got us talking about ears. This led to a cursory review of each family members ears, which quickly led to a more scientific approach to determining how each members ears measured up.


The scientific data gathering included taking a napkin around the table, holding the napkin up to each person's ear and marking the distance from the ear lobe to the top of the ear. The results were predictable, with one surprise in that Heidi had the longest ears of all. I find it interesting the relatively small difference between a 2-year old ear and that of an adult. 3/8" is all that 35 years will add to Saul's ears.

At the time we didn't consider measuring ear protrusion, or the distance an ear sticks out to the side of one's head. Based on informal research, Saul easily takes the cake, although it might be a proportional thing where at a young age the ear appears to stick out more.

Anyhow, supposing this to be interesting research history for us sometime down the road, and on the off chance our results might be interesting to someone else, I'm posting the visual results.
