Baby's size

This is my first child. I'm nervous about having a giant because well my husband is 6'5 and 280lbs. His side of the family does not have tiny babies, infact he was 10.5 lbs and all of his nieces and nephew are like 8lbs or bigger when born. My side so far is only my half brother and half sister their babies haven't been tiny either. Not to mention I was a big baby but I was 2 weeks late(9.5lbs). Im only 5'4 and I'm heavy but that's cuz I haven't tried to work out In a few years. I'm just curious if parents size and nieces and nephews show any indication about what size the baby will be?
