Stair Calculator: Terminology To Build Stairs, Distinguishing Between Stringer And Tread, And Calculating The Number Of Steps

What is the Common Terminology for Building Stairs?, a trusted online resource for various calculations, offers a comprehensive Stair Calculator. This powerful tool allows you to calculate and understand key objectives and terminology associated with stairs. By utilizing the Stair Calculator from, you can accurately determine the parameters and make informed decisions regarding stair design and construction. Let's delve into the details and explore the fascinating world of stair calculations.

Stringer-It is the Structural part of the stairs. It is the place on which steps are mounted.
Tread- The horizontal portion of the steps on which a person steps.
Riser- Between the two consecutive treads. It is the vertical portion of the stairs.
Angle/Inclination: It is the inclined portion of the stair.
Landing: It is the portion of the stairs that connects two steps.
Nosing-It is a part of the stair tread that hangs on the riser.
Flush Mount-The last Tread is beneath the floor level. It is the same height as the floor level.
Handrail: It is the railing that runs along the stairs. It is present to avoid falling through stairs.
Width-It is measured from the edge of the stair to the other edge of the Tread.

These are the parameters concerning the Terminology and its building code. The building code differs from region, but there is a minimum criterion. Depending on that, the StairCase is Calculated.

Difference between Stringer and Tread

Staircase Construction comes with various factors. The type of staircase, material, and components that will be used. Let's understand the basic Stringer.

It is a vertical supporting board. The structural member runs on each side or in the center of the stair. Now the stringer treads and risers are fixed. There are various types of materials used to make different types of stringers.
The Stringers are formed using steel, wood, and aluminum. Now they have pros and cons. It could be constructed in a residential or commercial space, depending on the need and place.

The Tread is the horizontal portion of the staircase. It is the portion on which a person steps foot. It is the integral portion of the stair. Hence the Tread is Below the riser of the Stringer.

How to Calculate the Steps while Constructing Staircase?

Calculate the Stair Stringer, the rise, and the run. The second and most important factor after this is the number of stairs. Understanding the number of steps constructed to build a staircase is crucial.

Most of the time, the calculation of the steps needs to be corrected. It is unclear if one looks at the stairs with the standard mount. The calculation can be done separately with a flush mount. Here is a rather simple and easy way to calculate the steps.

There are two types of staircases. One is flush, and the other is a standard mount.
Regardless of the type of Stringer, count the number of steps one takes while climbing instead of sliding.

Hence this makes it easy to count the number of steps needed to construct the stairs. Civil Engineers use this technique to calculate the required steps and begin construction using building codes and Terminology.


The Stair Calculator needs the Terminology and building codes. It is needed to build a staircase. Calculating the number of steps and parameters is included in constructing a staircase.
