Concrete Stairs Volume Calculator
Your measurements : number of risers, riser height, tread depth. Your estimate : volume, litres, cubic feet.
How the calculation works
Concrete Stairs Volume Calculator
Width × Tread depth × Riser height × n(n + 1) / 2 × (1 + Waste allowance / 100); n = Number of risersBefore you order
- Use the coverage, yield and dimensions printed on your product. Waste allowance is adjustable; real cuts and site conditions may change the order.
- Solid steps filled down to ground level. This is not the volume of a suspended stair slab.
- Planning estimate only. This is not a structural design, a safety approval or a local code check.
