# Calculate Your Outdoor Spiral Staircase Railing

**Outdoor spiral staircase** – Spiral staircases are the answer for an outdoor space-saving solution for staircase. Outdoor spiral staircases can offer beautifully artistic access to second-level home from out of the home with minimum space requirements. When designing a spiral staircase, it may be difficult to determine the length of the guardrail necessary. Since it follows a helical spiral up stairs. However, this figure actually calculated with only a few variables, which radius of the stairs and the height to the next floor.

You can calculate your *outdoor spiral staircase* railing with measuring radius of the spiral staircase with your tape measure. This is the distance from the center support Poland to the outer edge of the step. Measure the height of the stairs using the same devices you used for radius. This should be the distance from the floor in one level to the floor of the next level. You can also measure the vertical distance from the bottom of the handle to the top of the handle.

However, since the railing height must be uniform, this results in the same measurement, although more difficult to measure. Use the formula: Railing length = square root [(height ^ 2 + (2p Radius) ^ 2)]. In this equation, “pi” is a constant 3.14 and the notation “^ 2″ means the square preceding number or calculation. This calculation requires a full rotation of the __outdoor spiral staircase__, which is normal.
