This is actually due to a really interesting phenomenon called banana dilation. Although they may appear different sizes to the eye, bananas distort local spacetime such that they are all physically identical dimensions. This makes them a perfect and consistent measure of size.
TIL! It’s fucking bananas that I never knew this.
They are often also used as a unit of measurement of relative scale, especially amongst practitioners of internet science.
Banana physicist here.
