To measure stair stringers start by dividing the height by the approximate rise to determine the total number of steps and then take the difference to find the exact rise of each step.
Find the total rise of the stair the first measurement to determine is the distance between the top and bottom of the stairs.
To find the height extend a level out across the upper edge of the entry point and stretch a tape measure from the bottom of the board to the ground.
But don t just measure up from below the top landing point.
In addition we will show you how the stair stringer calculator works out the rise run angle and stringer length allowing you to plan the layout of your intended staircase effectively.
Either follow these calculations through or simply use the calculator to get your diy project off to a breeze.
Instead level over approximately to where the bottom of the stair will land step 1 in the illustration above the vertical distance between the bottom and top of the stair opening is distance x which in.
