Fact: Muscle weighs more than fat.
If your char is going to be a professional hockey player, they're going to weigh a lot more than someone who leads a less active lifestyle.
For the following heights, the weight range is as follows:
5'0": 102-128 lbs.
If your char has a heavier build (like Tanya and Grin) then it is permissible to go above the weight range. However, going lower is a sign of being underweight and possibly malnourished.
5'1": 106-132 lbs.
5'2": 109-136 lbs.
5'3": 113-141 lbs.
5'4": 116-145 lbs.
5'5": 120-150 lbs.
5'6": 124-155 lbs.
5'7": 127-159 lbs.
5'8": 131-164 lbs.
5'9": 135-169 lbs.
5'10": 139-174 lbs.
5'11": 143-179 lbs.
6'0": 147-184 lbs.
6'1": 151-189 lbs.
6'2": 155-194 lbs.
6'3": 160-200 lbs.
