Introduktion
Stairs Calculator — Steps, riser and run from total rise. Enter Total rise (cm), Target riser height (cm), Tread depth (cm) to get an instant, accurate result.
Formel
Steps = ceil(total rise / target riser height). Actual riser = total rise / steps. Total run = (steps − 1) × tread depth.
Steg för steg
- Enter the Total rise (cm).
- Enter the Target riser height (cm).
- Enter the Tread depth (cm).
- Click Calculate to see your result instantly.
Verkligt exempel
Example: With Total rise (cm) = 270, Target riser height (cm) = 18, Tread depth (cm) = 28, the Stairs Calculator gives Steps: 15, Actual Riser: 18, Total Run: 392.
Vanliga Frågor
Why is the actual riser different from my target?
Since the number of steps must be a whole number, the riser height is recalculated to divide the total rise evenly.
What is "total run"?
The total horizontal distance the staircase occupies, based on tread depth and the number of steps.
What inputs does the Stairs Calculator need?
You'll need to provide: Total rise (cm), Target riser height (cm), Tread depth (cm). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Stairs Calculator?
The Stairs Calculator applies the formula exactly as calculated — Steps = ceil(total rise / target riser height). Actual riser = total rise / steps. Total run = (steps − 1) × tread depth. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Stairs Calculator free to use?
Yes, the Stairs Calculator is completely free, requires no signup, and runs instantly in your browser.
Om Trappkalkylator
The Stairs Calculator uses a real, verifiable formula — Steps = ceil(total rise / target riser height). Actual riser = total rise / steps. Total run = (steps − 1) × tread depth. — so results are accurate every time, not an approximation.
