Repairing existing deck need to make risers for steps 12 steps high any tips how to measure and cut

Did the odl deck have these 12 steps? If so, use the risers of the old steps as a template for the new steps. Otherwise, your steps need to have 12" treads and a 7-1/2" rise between the steps.

to lefty: you need to be more specific when you advise a 7.5 riser. When cutting stair stringers there are formula's that have to be followed in order for stairs to acheive proper run and rise. This formula can be found on search web for stairs. TheWoodMan.

To Woodman: Lefty told him right. You replace what was there. Use the old for a template. I built at least one set of stairs every day for some job or another. I don't need any other web site to look at.

12" tread wirh 7.5" risers are good. However, if that doesn't fit your needs, you can use the formula T+2R=26 (where T is tread width & R is Riser height) to get other suitable Tread to Riser ratios.

As a rule of thumb. . .the sum of the height of a riser and the depth of a tread should equal between 17" and 18".
Best riser height is between 7" and 8". The sum of two risers and one tread should be between 24" and 25".
The width of the tread should be at least 36". Wider is better. 3'2" to 3'4" is preferred, but an outside deck stair is
best built to suit you and look like it was intended that way.
The stringers for the stair should be made from 2x12. The treads could be either 2x10 or 2x12, and the risers can be 2x6, 2x8, 1x6, or 1x8. All should be CCA.
Find the the total rise (vertical distance) and divide it by the intended riser height. Start with the 7. This is your number of risers. Disregard the fraction. To get the individual (unit) rise, divide the total rise by the number of risers. This is the height of each riser.
Using the 17" to 18" rule subtract the riser height and the remainder is your recommended tread depth.
You could predetermine where you want the steps to end and divide the number of risers into that number to calculate the tread depth.
Use a framing square and "step off" the riser and tread height on a stringer. Repeat the stepping off process. Count the correct number of steps to be cut before you cut the board to length. It is better to have an extra than to be too short.
If necessary, rip the treads to their respective widths and cut them to their approx. 3 foot lengths (if that's what
you choose). You might need to cut at least 3 full stringers to eliminate any possibility of sag in your stair treads.
When you assemble the parts the riser boards go on before the treads. On an outside stair, riser boards are optional and not necessary. Then attach the treads. Keep in mind that you can cut the tread depths wider if you want overlap.
Attaching the stringers to the deck has many variables. Your choice on methods and techniques. Your stair should have a handrail and probably spindles. The pattern should match the existing deck.
