There is no universal agreement on weight divisions within womenâs professional boxing, but amateur weight divisions are: 1  flyweight, not more than 106 pounds (48 kg) 2  bantamweight, 112 pounds (51 kg) 3  featherweight, 119 pounds (54 kg)  lightweight, 126 pounds (57 1  kg) light welterweight, 132 pounds (60 2  kg) welterweight, 141 pounds (64  kg)
McGregor will undoubtedly be the bigger man on fight night, as he typically walks around close to 170 pounds before boiling down in the lead-up to competition. Mayweather rarely strays much higher than 150 pounds, and fought much of the latter part of his career at the 147-pound welterweight limit.
