Oh. five-and-a-half feet. Two feet either side, 18" for the walkway.

The Americans With Disabilities act may mandate a 36" walkway... Of course
there is lighting to consider. And fire walls.


I use a walkin closet as a dressing room as well. Often two people at once.
I prefer a 3 foot walkway in closets. 5 foot depth for hanging on one side.
80 inches deep for hanging on both sides. 4 foot walkway in storage rooms.
For storage 8 feet works well with cupboards on both sides. 6 feet for one
side.
