Staircase Calculator
Plan and design your staircase with precision for your construction project
How to Use This Calculator
Basic Calculator
The basic calculator allows you to quickly design a staircase by entering just four key measurements:
- Total Rise - The vertical height from the bottom to the top of the staircase
- Total Run - The horizontal distance covered by the staircase
- Headroom - The minimum clearance above the stairs
- Step Width - The width of each step
Advanced Calculator
The advanced calculator provides additional options for more precise staircase design:
- Set minimum and maximum values for risers and treads
- Specify nosing depth and stringer dimensions
- Choose stair type (straight, L-shaped, U-shaped, or winder)
- Add a landing and select construction material
- Toggle between imperial (inches) and metric (cm) units
Understanding Results
After calculation, you'll receive detailed information about your staircase:
- Number of steps required
- Actual riser height and tread depth
- Staircase angle and total stringer length
- Material estimates (advanced calculator)
- Code compliance assessment
- Visual representation of your staircase profile
Building Code Tip
Most building codes require risers between 4-7.75 inches and treads at least 10 inches deep. The calculator will warn you if your design falls outside these parameters.
