Well, no customary measurements because it wouldn't fit between the pins and it only goes to 1inch, which 15pins is longer than that.
So, from the cheap chi-com one with meteric sizes:
from the outside of pins 1 to 15 is 35.92mm
from the inside of pins 1-15 is 34.01mm (basiclly full length, less the size of two pins)
from the outside of pins 1-2 is 3.48mm
from the inside of pins 1-2 is 1.48mm (the space between two pins)
the width of pin 1 was .98mm (pin 15 was a little smaller, but it had a nick on it)
Please let me know what measurements you have. Thanks.
