Each sanctioning body publishes its ratings on its own schedule, so the columns above are dated separately. Where a body leaves a position vacant, and the IBF routinely does at ranks 1 and 2 pending an eliminator, that is shown rather than hidden.

Minimumweight division limit

The minimumweight limit is 105lb, which is 7 stone 7lb or 47.63kg. A fighter must make this weight at the official weigh-in, normally held the day before the bout. Missing it forfeits the right to win a title in the division, though the fight itself usually still goes ahead.
