Spike's Calculators

The Simple Stairs Calculator is an easy-to-use tool for builders, architects, and DIY enthusiasts to calculate essential measurements for staircases. It provides accurate calculations for riser height, number of treads, total run, and stair angle. Whether designing a new staircase or renovating an existing one, this tool ensures your measurements are precise and easy to follow.

- Floor-to-Floor Height Input: Enter the height from the bottom to the top floor in inches.
- Tread Depth Input: Specify the depth of each stair tread in inches.
- Denominator Selection: Choose the denominator for fractional calculations (1/16, 1/8, 1/4, 1/2, custom).
- Results: Instantly obtain the number of risers, riser height (both decimal and fractional), number of treads, total run, and stair angle.

- enter the height from the bottom to the top floor in inches (e.g., 120 3/4)
- specify the depth of each tread in inches (e.g., 10)
- choose the desired denominator for fractional calculations(a useable fraction)
