My intention is to put in bifold doors for a closet that previously only had curtains. It is an old house and nothing seems to be standard in size. The height of the closet is 79.5". I see almost all doors come in 80". Would that fit for this project? I have been searching for a chart that would say what size to buy based on the size of the opening but I have failed to find one. I know the doors are on a track but couldn't tell if the 80" size was the finished size (including the track in the measurement) or it was the size of the opening it fit. I would appreciate the knowledge of the forum for this bifold door newbie! Thanks!
