Free Stair Calculator
"A Stair Calculator is an online tool used to compute key stair dimensions like number of steps, riser height, tread (run) depth, stringer length and stair angle based on the total vertical height between floors — making safe and comfortable stair design fast and accurate"
📌 What a Stair Calculator Is?
A stair calculator is an online tool that helps you figure out the main measurements needed to design or build a staircase. It removes the guesswork so you get safe, comfortable, and correct stair dimensions.
📏 Key Things It Calculates
When you enter basic measurements like the total rise (vertical height from lower to upper floor) and sometimes the run (horizontal distance), the tool can calculate:
Rise per step (vertical height of each step)
Run or tread depth (horizontal part you step on)
Number of steps needed
Stringer length (structural support board length)
Stair angle (how steep the stairs are)
These are essential to make stairs that are comfortable, safe, and meet building code criteria.
🛠️ How It Works
You enter values like total rise and either the run per step or the total run.
The calculator applies basic geometry and building standards — for example, splitting the total rise evenly and using formulas to find lengths and angles.
Some versions let you choose number of steps or rise height manually if you prefer a specific design.
📐 Why It’s Useful
Saves time by doing complex math for you
Helps avoid mistakes that can make stairs unsafe or uncomfortable
Ideal for builders, architects, DIYers, and renovation projects
Gives code-based suggestions so stairs comply with safety standards like proper step height and tread width
