Measuring for spiral stairs can be a tricky job, especially if you have never done it before. This project is a good one for anyone who is moving into a new home or remodeling their current home. Here are a few materials you will need, along with some steps that can help guide you through the process of measuring for your own spiral staircase.

Step 1 - Measure Width and Depth

Begin by measuring both the width and the depth of the opening for your spiral staircase. You can purchase spiral staircases in kits, so that you can round to the nearest size and accommodate the space. You must to consider how many times you want the staircase to wind when you are measuring. That will affect both the width and depth of the stairs.

Step 2 - Measure Floor Height

You will need to measure the actual height. Here you have to measure the floor to floor height so that you will be able to plan out how often to turn the spiral, as well as how high the stairs will be. Measuring the total space also helps determine how staggered the steps will need to be, as well as how far apart in height. Remember that while you are measuring, you need to write down the measurements as you go. Take each measurement several times for the most accurate measurement. Accuracy now prevents problems later.

It is best to check at a different spots, as the area may be uneven at some points. Unevenness is typical when you are measuring for windows, but it is also common for stairways and walls to match unevenly, especially in older homes. Even if you measure 3 times at different spots and find that the measurements are the same, you will have at least measured a few times to ensure that you are accurate.

Step 3 - Consider Your Materials

Keep in mind while measuring what kind of stairs you will be installing. While they are spiral, you also want to consider where they are going and what type of material they will be made of. If your stairs are going to be outside, you will need to decide how they will be attached and plan the temperature change. Some materials will expand and shrink in the weather. Different materials will be attached in different ways, so measuring will have to take into account the type of fittings and attachments that will secure the stairs.

Once you are finished, you can consult with a professional to install your stairwell. Be sure that as you go along you make adjustments to height when necessary.
