This means that a handrails height is measured from the top of the stair treads or horizontal stepping members. Step 2 Measure the overall length.
Most building codes require handrails for exterior stairs to be between 34 inches and 38 inches above the stair nosings.
How to measure for exterior stair railing. Of the rail and the single hole for the foot block faces down. Using a tape measure make measurements of the total height of the space you want to make stairs from the bottom to the top. Clamp the bottom rail to the post then measure the length of the footblock.
Once the angle has been cut on the top of the lower post measure on the front of the post the distance between the lower Ref. The overall height is the distance from the floor or landing at the top of the set of stairs to the floorlanding at the bottom of the set of stairs. The parameters asked should be entered in mm or items where it is applicable.
The proper way to measure the staircase railing height is to start from the end of the stair nosing and continue measuring upward to the railings top. The appropriate staircase railing height ranges from 34 to 38 inches. Trim and handrails may not encroach into this minimum width by more than 3 12 inches.
Point to the angle cut shown as 28 78 in diagram C. Ensure the pickets are centered between the posts and mark the rail angle. The basic parameter to measure how the entryway is convenient is the calculation done by the formula based on a human step size.
The final measurement to acquire is. Private stairways shall be a minimum of thirty-six inches wide. 5 Easy Steps For Measuring Step 1 Measure the overall height.
Measure the height or rise of the space you want to make stairs. But we point out that in general the minimum recommended stair width is between 34 and 36 Across the width of the tread. Overall length is determined by measuring the horizontal distance from the edge of the nosing on the first tread at the bottom of the staircase to the edge of the nosing on the floorlanding at the top of the staircase.
To determine the length of the footblock place the footblock next to the rail on the step that the footblock falls on. To determine the position of the upper 2×4 rail on the upper 4×4 post transfer that same measurement to the upper post as shown in the diagrams. Calculating the length of your stair railing actually is actually based on a fundamental relationship in geometry called the Pythagorean Theorem which basically states in terms of railing that the squared length of your stair railing is equal to the squared rise of your stairs the squared run of your stairs or A2 B2 C2.
The stair nose serves as the exterior projection of the stair tread. Steps rise and run for stairs.
