A deck with a 36-inch rise using 7-inch risers and 10-inch treads requires 6 steps.
How to use this tool
- Enter the total vertical rise (floor-to-floor height) in inches.
- Enter your target rise per step (7 to 7.75 inches per code).
- Enter the desired tread run (10+ inches per code).
- The calculator returns exact step count, actual rise, and total horizontal run.
Calculate the number of steps needed to reach a standard 3-foot-high deck, one of the most common deck heights for residential homes.
Frequently asked questions
- How do I calculate stair rise and run?
- Divide the total vertical rise by your target rise per step to get the number of steps (round to nearest whole number). Then recalculate: actual rise = total rise ÷ steps.
- What is the code for stair rise and run?
- IRC building code requires a maximum rise of 7-3/4 inches and minimum run (tread depth) of 10 inches per step. Check local codes as they may vary.
