STAIR LAYOUT EXAMPLES STAIR LAYOUT DEFINIT IONS Rise: The “floor-to-floor” or “landing-to-landing” rise is the actual vertical rise required for building a stairway after the finish flooring has been in- stalled. Run: The run of a stairway is the amount of horizontal space required. The total run of a stairway is equal to the width of each tread multiplied by the number of treads. - Page 86 Number of Risers: The number of risers includes both the first and the last riser of the stairway. Riser Overage or Underage: The riser overage or underage is the dif- ference between the “floor-to-floor” rise and the total height of all of the risers.

Stairs — Given Floor-to-Floor Rise You’re building a stairway with a total rise of 9 feet 11 inches. Your de- sired riser height is 7-1/2 inches and desired tread width is 10 inches. Find the riser height; number of risers; riser underage/overage; tread width;... -
Page 88: Stairs - Given Rise And Run
Stairs — Given Rise and Run You need to build a stairway with a floor-to-floor height of 10 feet 1 inch, a run of 15 feet 5 inches, and a nominal desired riser height of 7- 1/2 inches (default). Find all stair values. Keystroke 1. -
Page 89: Stair Risers Only - Custom Height
Stair Risers Only — Custom Height You’re building an access stairway for a client who can’t handle con- ventional-height stairs. If the total rise is 3 feet 9 inches and your de- sired riser height is approximately 5-1/2 inches, find the actual riser height, number of risers and underage or overage remaining. -
