Spiral Staircase Height & Riser (Step) Height

Paragon spiral stairs offers several base models that are adjustable height spiral stairs as indicated in the heights (will fit). This is helpful when final finished floor-to-floor height has yet to be set and or if the final floor-to-floor measurements are still undetermined.

Adjustable Height

Adjustable Height means that you can set the riser heights when you receive the stair. Therefore, if you originally calculate your floor-to-floor height to be 100 inches and then later re-calculate and learn that the actual height in two inches bigger, do not worry because Paragon stairs have adjustable risers.

The correct number of treads on your spiral stair are predetermined based on the anticipated height of your project. In order to determine how many treads your stair will have take your finished floor to floor height and divide it by the maximum rise height of 9.5.

Keep in mind the straight stair riser height and spiral stair risers height is different. Most straight stairs have a typical riser height between 7” – 7.5” whereas spiral stair riser height has a maximum riser height of 9.5”. The reason for this is that as all the treads are set to a near 30 degree angle.

Example: if your finished floor-to-floor height is 12 feet, that translates to 144 inches. 144 inches / the maximum spiral stair riser height of 9.5 inches = 15 treads

Spiral staircases bring a certain charm and elegance to any home, but what about the height of the steps? Maximum staircase riser heights are set for safety reasons, so knowing the specs of your staircase is important. At Paragon Stairs, we understand that you may need more flexibility when it comes to stairs height. That’s why we have adjustable staircases that fit within regulations.

The maximum height step permitted for most spiral staircases is 9.5 inches and there must be a minimum of 6 inches between each tread riser. This means that if you’re looking to build a staircase that has an overall height of 12 feet, the total number of steps required is 15 since 12 divided by the maximum rise height (9.5) is 15.

No matter the height of a riser, Paragon stairs has adjustable risers that meet safety requirements yet still fit within your needs. This means if you’ve already calculated the floor-to-floor measurements and find out later that it was two inches taller than expected, you’ll still be able to adjust the riser height of your stairs. Unlike traditional stairs, an adjustable staircase takes the headache out of staircase height problems.

At Paragon Stairs, we’re dedicated to providing adjustable spiral staircases that fit all types of homes. We understand that spiral staircases are designed for safety as well as aesthetics and our adjustable risers allow you to have both in one package. So, if you’re looking for a staircase with adjustable height steps, Paragon Stairs is your best option. With our aesthetically pleasing adjustable risers that adhere to safety regulations, you can have the spiral staircase of your dreams without worry!
