Do Your Ears and Nose Really Keep Growing?

You’ve probably heard the old joke — “the ears and nose are the only parts that keep growing until you die.” Turns out, there’s more truth to it than you’d think.

While most of the body’s growth slows and eventually stops after puberty, the ears and nose appear to break the rules. They don’t actually grow in the same way they did during childhood, but they do change shape and size over time — giving the illusion of continuous growth.

The real reason lies in the structure of these features. Unlike bones, which stop lengthening in adulthood, the nose and ears are made mostly of cartilage and soft tissue. As we age, the collagen and elastin in these tissues weaken, and gravity takes its toll. The cartilage continues to grow slowly, but more importantly, the skin and supporting structures lose elasticity. This causes the ears to stretch and the nose to sag, making both appear larger and more prominent with age.

It’s not a dramatic increase — just a subtle, gradual change over decades. Studies have shown that ear length increases by about 0.22 millimeters per year on average, which adds up over a lifetime. The same principle applies to the nose, where cartilage continues to expand, especially at the tip and sides.

So, while your limbs and torso may stop growing in your late teens, your nose and ears quietly march on. They’re not really “growing” like they did when you were a kid — but they’re definitely changing. In a way, they’re the only parts of you that never truly settle down.
