Nosing â An edge part of the tread that protrudes over the riser beneath. If it is present, this means that, measured horizontally, the total ârunâ length of the stairs is not simply the sum of the tread lengths, as the treads actually overlap each other slightly.
All of our treads are 11 1/2â³ wide and 1 thick. All of our treads allow for a 1 1/2â³ overhang over the riser. This overhang allows for a 3/4â³ cove underneath the overhang. The size of your tread is the full coverage of the ârunâ from the wall or edge of the riser to the outside edge of the riser on the other side.
