They are the height it needs to be in order to make the desired number of treads connect the low and high points. That being said, Stair risers should be no more than 8" and treads should be no less than 11". Once your risers start being taller than your tread is long, you are building a ladder, not a stair. If you start at 8" for a riser and 11" as a tread, By shrinking the riser and adjusting the treads to fit you can get the steps to work out so that one consistent riser height can be achieved. One that will be in the 6-8" range. If you use risers that are less than 6", you should lengthen the treads. Example problem--
Lower floor is 6 feet lower than the higher floor. Keep in mind you always have 1 more riser than tread.
6'-0"= 72"
You can make 18 each 4" risers (72"H /4"R=18 risers) and have a run of 34 feet using 24" treads.
or
you can make 12 each 6" risers and have a run of 11 feet using 12" treads.
or
you can make 9 each 8" risers and have a run of 7'-4" or 88" using 11" treads.
You will always have at least one "given"-the height you need to traverse. From there it is just division and multiplication based on the 8" maximum riser and the 11" minimum tread.

To install stair risers effectively and securely, follow these steps: Measure and cut the riser to fit the height of the stair. Apply construction adhesive to the back of the riser. Place the riser against the stair tread and secure it with finishing nails or screws. Repeat for each stair riser, ensuring they are all level and securely attached. Finish by caulking any gaps and painting or staining the risers for a polished look.

To install risers on stairs effectively, follow these steps: Measure the height and width of each stair riser. Cut the riser material to the appropriate size. Apply construction adhesive to the back of the riser. Press the riser firmly against the stair tread. Secure the riser in place with finishing nails or screws. Repeat the process for each stair riser. Allow the adhesive to dry completely before using the stairs.
