Information

A single-flight straight staircase with a solid diagonal structure accentuates the height of the room and provides ample space even in a house with small dimensions. The stylish appearance of the staircase is enhanced by long railing rods that rise like strings up to the opening, attached to the ceiling of the first floor.

A single-flight staircase to the second floor takes up minimal space when one side is placed flush against the wall. The bottom step and landing form a unique inviting area, allowing the start of the single-flight staircase to be placed even in corners with solid walls.

An excellent online calculator for calculating a straight staircase to the second floor will help you not only determine the convenience of the staircase but also provide detailed information on the manufacture of the stringers and steps. With the obtained data, you can easily make the structural elements of the staircase from wood or metal and assemble it without resorting to the services of expensive carpenters.

Features of this calculator:

The interactive system of this script is primarily aimed at helping you choose the structural solution for such an important part of your home decor as the staircase.

This calculation program implements the following tasks for you:

  • Helps you assess the convenience of the staircase
  • Helps determine the dimensions of the opening in the floor
  • Calculates the optimal angle of inclination necessary for walking
  • Helps determine the required amount of materials and their overall dimensions needed for your project
  • Compiles the necessary minimum drawings for production and installation

 Data for determining the convenience of a straight staircase:

To use this online single-flight straight staircase calculator, you do not need special knowledge. It is enough to remember the basic rules and rely on them during the calculation.

  • The optimal angle of inclination of the staircase (stringers) is between 30 and 40 degrees. At other values, the comfort of use when moving between floors is significantly reduced. In turn, this can lead to a decrease in safety and speed of movement.
  • The width of the step, optimal for human walking, ranges from 27-32 cm. If for some reason it is not possible to maintain this width, try adjusting it by overhanging the edge of the step. Keep in mind that the maximum overhang of the step should not exceed 5 cm.
  • Also, do not forget about such a parameter as the "average step length." According to this basic criterion, the convenience of the future staircase is calculated. The sum of the width of two steps and the sum of two riser heights should equal the average step length of a person and should not exceed 63 cm.

Necessary initial data.

To get the most accurate calculation of a single-flight straight staircase, you first need to determine several initial parameters. You need to know the exact height of the floor, the width of the staircase flight, its allowable length (the space you can allocate for the staircase in the overall interior of the room), and the junction point with the floor. You may need to calculate several options before deciding on the most suitable one.

This calculator is easy to use and is provided to you completely free of charge. Try, experiment, and get ready-made drawings for the stair flight in your private home.
