I always thought that you just measured across your palm from base of index finger to base of little finger and the distance in cm is your glove size. Seems straightforward to me…How about BMW Motorrad gloves - sized 6 through 12.
WTF does that mean in the real world???
The main thing about sizing is consistency. You’ll never get it between manufacturers but I always know that if I buy a BMW item in regular size 52, it will be exactly the same as another similar item of regular size 52 whether it’s jackets or trousers.
Almost same worth.
