I am going to be installing a set of steps from my porch to my patio. I took measurements from the one on the back side and I see the steps are 6 1/2" high. I would like to build the new one at the maximum of 5" to better accomodate my family. Is this even possible? How do I figure the length of the frame? The deck is 33 1/4" high.

It's simple math though, the stinger is the hypotenuse of the right angle triangle and the square of the hypotenuse equals the sum of the square of the opposite two sides.

When you get your total rise though make sure you are measuring from finish to finish, not to framing.

If you are going to make the step rise lower you typically need to compensate with a longer tread to make it comfortable.

Here a 3 basic rules carpenters use when designing stairs. You can use any one of these that you prefer to come up with the tread width & riser

height for a comfortable set, and of course always check your local codes.

1. The sum of two risers and one tread should be 24 to 25 inches.

2. The sum of one riser and one tread should be equal to 17 to 18 inches.

3.The height of the riser times the width of the tread should equal between 70 and 75 inches.

Never make a tread below 9 inches.
