Parameters
Height
Vertical distance between the lower floor and the upper floor.
Diameter
Diameter of the staircase.
Length
Length of the staircase.
Width
Width of the staircase.
Step number
Easystair automatically calculates the best value. Just click on the lock to change it.
Number of steps that compose the staircase.
Diameter of the column
Length of the column
Width of the column
Overlap
Part of the step covered by the top step.
The overlap improves the comfort of the staircase.
Steps thickness
Angle of the steps
Easystair automatically calculates the best value. Just click on the lock to change it.
Angle
Easystair automatically calculates the best value. Just click on the lock to change it.
Angle formed by the landing.
Landing thickness
Upper floor thickness
Blondel's law
Easystair automatically calculates the best value. Just click on the lock to change it.
G + 2H = 590 to 650mm (23.2 to 25.6")
Formula invented by the French architect François Blondel (1618-1686) checking the coherence between the step height and the going.
The ideal value is 630mm (24.8").
Walkline radius
Easystair automatically calculates the best value. Just click on the lock to change it.
Fictitious line symbolizing the user's passage.
It is used to determine the going for turning staircases.
If the stair width is less than or equal to 1m (40") then the walkline is located in the middle.
If the stair width is greater than 1m (40") then the walkline is located 500mm (20") from the inner handrail.
Angle of rotation
Angle between the 1st step and the landing.
Step number
Number of steps that compose the staircase.
Angle
Determine the slope of the staircase.
The angle should be between 20 and 50°. Its ideal value is 30°.
Step height
Vertical distance between two step nosings.
The step height should be between 150 and 200mm (6 and 8").
Its ideal value is 175mm (7").
Going
Horizontal distance between two step nosings.
The going should be between 230 and 330mm (9 and 13").
Its ideal value is 280mm (11").
Angle of the steps
Blondel's law
G + 2H = 590 to 650mm (23.2 to 25.6")
Formula invented by the French architect François Blondel (1618-1686) checking the coherence between the step height and the going.
The ideal value is 630mm (24.8").
Headroom
Distance between the landing and the walkline.
The headroom should be greater than 1900mm (75") and its ideal value is greater than or equal to 2100mm (83").
