That makes sense.

Just to clarify, hand bones are metacarpals and finger bones are phalanges. Thumb is #1, pinky is #5. So the joint between the palm and the finger is the metacarpo-phalangeal or MCP joint. All the fingers except the thumb have two interphalangeal joints, proximal and distal or PIP and DIP.

Measuring that way, I get 3-1/8" for my middle finger and 2-7/8" for the index finger on the left, about 1/8" shorter on the right. So a bit longer than your fingers but in the same ballpark!
