How to calculate a ladder on a stringer online?

It is possible to make exact calculation with a stair stringer calculator. We will try to visually go through the whole process.

Measure and enter the main dimensions of the structure – the parameters of the stairway, measure the distances between the levels of the clean floor of the second and first floor. Then fill in data on stair steps, stringer and step.

As a result you receive 3D model of the ladder designed according to your parameters, the final calculation data on a ladder design, which includes an angle of slope of the ladder, number of steps, height and width of each step of a straight wooden ladder. The ladder calculation program will draw four detailed drawings of a straight ladder on stringers:

  • side view of the ladder
  • top view of the stairs
  • straddle draw
  • stair drawing
