Suggestion/observation of arm span in boxing...

[imaioral]

Good evening guys...

I was wondering one day of these about the arm span measuring in boxing and today decided to write down. Getting the boxrec descriptions of arm's reach, I was thinking if the way boxers do to measure are wrong (as follows the picture example below) because if you think a little you use the gloves closed (of course ) and as soon as you measure your arm span with the hands closed (like if you were using gloves) the measure drops from 15 to 30 or more centimeters in comparison of them opened (you don't touch the opponent with the fingertips). I have 1.83 and 1.96 of arm span (based on boxrec description) and with the hands closed it drops to 1.80.

(Supposition): Is the common arm span measure in this case based on hand closed + thickness of wrap + gloves (or thickness of the gloves)? Looks like stupid but, what is the real explanation for this?

What do you think? Because if I'm right there must be a change in the way they measure boxers reach...

Thanks for all the attention!

REACH HAS ALWAYS BEEN MEASURED FROM MIDDLE OF BACK OR SPIN TO FINGER TIPS TIMES 2 WOULD GIVE YOU TOTAL REACH.
ACTUALLY SOME BOXERS SNAP THEIR JAB WITH OPEN HANDS SUCH AS DID BOB FOSTER AND ALI PLUS SOME OTHERS BUT THEIR MOST EFFECTIVE JAB WAS WITH CLOSED HANDS.

Fingertip to fingertip is used as it is an easily and accurately measured and gives a good standard approximation of reach. Other factors such as the length of the fingers and breadth of shoulders unnecessarily complicate the measurement.
