Is your pinky or your thumb longer?

Or are they the same size?

Answer: Longer pinky. Both hand.

Same size. my pinky is larger

pinky, by about 1cm my thumb is WAY longer on both hand than my pinky,

exactly the same - put them side by side and certainly compared. No guessing. thumb might be how a person is made to means it (cm works best)

quite frankly it depends on the party. :-) At this point I have to remind you adjectives that the thumb starts at the wrist...
