Twice the Rise plus the Going (2R + G) should be between 550mm and 700mm To continue with the previous example let’s select a low going of 220mm. RISER: – It is a vertical portion of a step providing support to the tread. Calculation example for real-world stair risers: Total rise measured R = 75" First calculation: Rise in inches divided by 7-inches. 5 1/4 LINEAL LAND TRD SQ EDGE. Method 2 : The walkline is located half-way along the stair width Method 3 : The walkline is located 2/3 of the way along the stair width, measured towards the inner handrail Method 4 : The walkline is located 50cm (20") from the outer handrail STEP: – It is a portion of the stair which provides upward or downloads movement.A stair is composed of a set of steps. This gives us 2 x 150mm + 220mm = 520mm.
