When measuring a box Retread the length of the tread is determined by the width of your staircase. Tread depth varies depending on the space the staircase is in. If the staircase doesn't have much space to go from the first floor to the second floor the tread depth will be smaller. Our standard tread depth is 11.5 inches. The smallest allowable tread depth is typically 10 inches, check your local building codes to confirm.
