Enter the height of your deck, tread depth, and riser height into the calculator to determine the total number of stairs needed.
Deck Stair Calculation Formula
The following formula is used to calculate the total number of stairs needed for your deck.
Total Stairs = Ceiling(Deck Height / Riser Height)
Variables:
- Total Stairs is the total number of stairs needed
- Deck Height is the height of the deck from the ground (inches)
- Riser Height is the height of each stair riser (inches)
To calculate the total number of stairs, divide the deck height by the riser height and round up to the nearest whole number.
What is Deck Stair Calculation?
Deck stair calculation refers to the process of determining the number of stairs required to reach a certain deck height from the ground. This involves understanding the dimensions of the treads and risers, as well as the overall height of the deck. Proper deck stair calculation ensures safe and comfortable stairs.
How to Calculate Deck Stairs?
The following steps outline how to calculate the deck stairs using the given formula.
- First, determine the height of your deck from the ground.
- Next, determine the depth of each tread and the height of each riser.
- Use the formula from above: Total Stairs = Ceiling(Deck Height / Riser Height).
- Finally, calculate the total number of stairs by plugging in the values.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem:
Use the following variables as an example problem to test your knowledge.
Deck Height = 96 inches
Tread Depth = 10 inches
Riser Height = 8 inches
FAQ
1. What is a riser height?
The riser height is the vertical height of each stair step.
2. How is tread depth different from riser height?
Tread depth is the horizontal depth of each stair step, while riser height is the vertical height.
3. How often should I use the deck stair calculator?
It’s helpful to use the deck stair calculator whenever you’re planning a new deck or renovating an existing one.
4. Can this calculator be used for different types of stairs?
Yes, you can adjust the tread depth and riser height fields to match the specifications of any stairs to calculate the total number of stairs accordingly.
5. Is the calculator accurate?
The calculator provides an estimate of the total number of stairs needed based on the inputs provided. For exact figures, it’s best to consult a professional.
