How do you measure a curved staircase?
Beside this, how much space is needed for a curved staircase?
3'6” translates to 42 total inches in diameter and therefore the MINIMUM opening size that you need MUST be 44 inches x 44 inches (44”x44”). You need at least 44”x44” opening because you'll need two extra inches for your fingers to travel along the handrail as you walk up and down the stairs.

In this way, how do you measure a spiral staircase handrail?
The length of a spiral staircase's helical handrail can be calculated by the diameter and height of the staircase.
- Measure the radius of the spiral staircase using your tape measure.
- Measure the height of the staircase using the same units as you used for the radius.
- Use the formula:
How much does a curved staircase cost?
A curved stair is the most expensive stair shape. Typically curved staircases start at about $8,000* and go well over $100,000 due to custom materials, styles and more complex engineering.
