My dad has two very small pinkies and so does my sister. I, on the other hand (pun intended), have one regular pinky and one short pinky. My left pinky from base to tip is 2.5" The right one is only a little over 2" From the heel of my hand to the tip of the pinky on the left is 5.5". Right is 4.75".

There's my weird measurement posting for your reading pleasure.
