Important: Choose the unit shown above; do not mix feet, meters, inches or other units within a dimensional set. Simplified stepped-volume model plus a continuous base slab; actual staircase geometry can differ. This calculator is for general planning/reference only. It does not replace project-specific engineering design, applicable local codes, manufacturer data, site investigation, or qualified professional review.

How to use this calculator

What to enter

Enter or select the following as requested: Dimension unit; Number of steps; Tread depth; Rise per step; Stair width; Base slab thickness. Follow the units, valid ranges, examples, and options displayed beside each field.

What the result means

The quantity or material estimate is based on the dimensions, coverage rate, layout, and waste allowance entered. Check the units, product coverage specifications, and whether openings, overlaps, cuts, or breakage are included.
