Our Stair Case Calculator estimates the volume and materials required for the given staircase details. On this calculator page, you can also calculate stair rise and tread and stair angle

This calculator gives you,

Waist slab (ft) = (√(Riser)2 + (Tread)2)

Number of Riser = Height of stair/Riser

Number of Treads = Length of stair/Riser

Volume of 1 step = 0.5 x Riser x Tread x Width of stair

Volume of Total step = Volume of 1 step x No of riser

Length of Waist Slab = (Number of riser x Tread)

Height of Waist Slab

Slant Height of waist slab = (√(Length of waist slab)2 + (Height of waist slab)2)

Volume of Waist slab = Width of stair x Thickness of Waist Slab X Slant Height

Total volume of stair (cft) = Volume of total step + Volume of waist slab

Total volume of stair (cum) = (Volume of total step + Volume of waist slab)/35.315

Dry volume of Stair in Cum  = Volume of stair x 1.524

Dry volume of Stair in cft = (Volume of stair x 35.315)

Cement Volume = (Dry volume x Cement)/sum of ratio)

Cement in kgs = (cement volume x 1440)

No of Cement Bags = (Cement Volume/0.035)

Sand Volume in cum= (Dry volume x Sand)/sum of ratio)

Sand Volume in cft = ((Dry volume x Sand)/sum of ratio)) x 35.313

Sand in Kgs = (Sand Volume x 1550)

Sand in Ton = (Sand Volume x 1550)/1000

Aggregate Volume In cum = (Dry volume x Aggregate)/sum of ratio)

Aggregate Volume In cft = (Dry volume x Aggregate)/sum of ratio) x 35.313

Aggregate In Kgs = (Aggregate Volume x 1350)

Aggregate In Ton = (Aggregate Volume x 1350)/1000

Terminology (Terms) of staircase calculator

GENERAL GUIDELINES:

1. The respective tread and riser dimensions for all the parallel steps should be the same on the consecutive floor of a building.

2. The minimum vertical headroom above any step should be 2 m.

3. Commonly, the number of risers in a flight should be restricted to twelve.

4. The minimum width of stairs should be 850 mm, though it is desirable to have a width between 1.1 to 1.6 m. Large stair widths should be provided in a public buildings, cinema halls, etc.

5. Staircase angle of inclinations should not more than 40 degrees horizontal.
