Stair Calculator
Stair’s construction is a painstaking task because it requires accurate calculations to guarantee structural integrity and safety. To assure perfection in the construction of stairs, François Blondel, a French architect, invented the Blondel formula. This formula is considered a goldmine amongst architects. It guarantees a pleasant stride to most people by performing calculations according to the following equation:
2 Riser + 1 Tread = 25 inches (63-65 cm)
François Blondel also created a 1-Riser variation of the Blondel formula to handle diverse use cases. The following expression describes the detail of that formula:
1 Riser + 1 Tread = 18 inches (46 cm)
These formulae serve as the foundation for any effective stair building project. They are also necessary to assess a staircase’s aesthetic and practical characteristics.
Apart from the Blondel formula, the concept of stairs construction involves various other terminologies. Therefore, before beginning the stairs calculation, one should be familiar with those terminologies. Here is a quick rundown of the various terms used in the building of staircases:
Guard or guardrails are vertical or horizontal obstacles put along the open sides of ramps or stairs in order to avoid falls. They are essential for staircases that are situated at high altitudes or in places where there is a chance of falling.
Handrails are rails that are positioned along the sides of a staircase to offer people support and direction. They are necessary for safety, especially when using stairs with several risers.
The part of the stair that you walk on when going up or down is called the run or tread. To offer varying degrees of comfort and safety, tread depth can be adjusted. However, a typical tread depth is between 10 and 11 inches.
The vertical space above the stairs, measured from the tread to the ceiling or any higher obstruction, is known as headroom. Enough space must be considered while building headroom to prevent people from running the risk of knocking their heads on the steps.
Nosing is the part of the tread that curves round and goes past the riser. They improve the aesthetic appeal and increase safety of stairs by reducing the risk of tripping.
Rise or riser refers to the vertical element that separates each tread. In order to ensure both comfort and safety while using the stairs, it is essential to consider a constant riser height.
The width of the stairwell includes the breadth of treads and guardrails or handrails. In order to guarantee user safety, the rulebook specifies setting minimum stair width. But it can vary depending on the expected amount of traffic and the planned purpose of the steps.
A structural element that holds up the treads and risers is known as stringer. They are essential in giving the staircase stability and support. They can be placed in the stairs or left exposed.
The computation of staircases can be overwhelming for beginners, especially when there is a lot to consider at once. But our stairs calculator is here to save the day. The tool features a basic and advanced version to cater to the requirements of both beginners and professionals. Here is the step-by-step guide to using this stair calculator:
Get started by entering dimensions, like total rise and run.
Select whether your staircase has ‘fixed rise (step height)’ or ‘fixed number of steps.’
Alternatively, enter the rise (step height) or number of steps.
Choose whether your staircase has tread or not.
Select whether your stair has headroom restriction or not.
Select an option between ‘Standard stringer mount’ and ‘Flush stringer mount.’
Finally, hit the ‘Calculate’ button to instantly receive detailed calculations.
