I hesitate to contribute to this discussion but my third and fourth finger lengths are below average accd to that chart. My palm is smaller than my brother’s.
Google tells me a small hand is less than 8.5 inches spanning from thumb to pinky, and less than 6 inches spanning from index to pinky. Mine is 7.5 and 5.5, respectively. NASA says I have a smaller than average hand size for females, based on their measurement from top of middle finger to the bottom of palm being an average of 6.8 inches, I come in a quarter inch shorter than that at 6.5. But my palm WIDTH in on par with them at 3-ish inches (or less depending on the part of the palm I measure).
