Millwork is manufactured in a planing and molding mill, while moldings are performed on site.

Question 12

How do you calculate risers and tread?

Answer 12

(Total rise in inches)
Number of risers: total rise/single stair tread depth (round up)
(Riser height)
Number of treads: number of risers subtracted by 1
Tread depth: (given) 2R+T=25” (use the riser night in inches to get the tread in inches)
