1. What is a Staircase Length Calculator with Steps?

Definition: This calculator estimates the total horizontal length (run) of a staircase based on the run per step and the number of steps.

Purpose: It helps architects, builders, and DIYers determine the space required for staircases in construction projects.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( L_t \) — Total length of staircase (meters)
• \( R \) — Run per step (meters)
• \( N \) — Number of steps (dimensionless)

Explanation: The run per step is multiplied by the number of steps to calculate the total horizontal projection of the staircase.

3. Importance of Staircase Length Calculation

Details: Proper staircase length estimation ensures compliance with building codes, comfortable stair dimensions, and efficient space planning.

4. Using the Calculator

Tips: Enter the run per step in meters (typical range 0.25-0.3m) and the number of steps (must be ≥1). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the standard run per step?
A: Building codes typically require 0.25-0.3m per step, with 0.28m being a common comfortable dimension.

Q2: Does this include the landing?
A: No, this calculates only the running length of the steps. Add landing dimensions separately.

Q3: How does riser height affect this calculation?
A: Riser height doesn't affect the total run length, but it determines the vertical dimension of the staircase.

Q4: What's the relationship between run and riser?
A: The sum of riser and run should be between 0.4-0.45m for comfortable stairs (2×riser + run ≈ 0.6m).

Q5: How do I account for winders or curved stairs?
A: This calculator is for straight runs only. Curved stairs require more complex calculations.
