How To Measure Stairs: A Comprehensive Guide

If you’re planning to install new stairs or replace existing ones, it’s important to know how to measure stairs correctly. Measuring stairs may seem like a daunting task, but it’s actually quite simple if you follow the right steps.

Step 1: Measure the Total Height of the Stairs

The first step in measuring stairs is to determine the total height of the stairs. This is the vertical distance from the floor to the top of the upper floor or landing. To measure the total height, use a measuring tape and measure from the floor to the top of the upper floor or landing. Make sure to measure at the highest point of the stairs.

Step 2: Measure the Total Width of the Stairs

The next step is to measure the total width of the stairs. This is the horizontal distance from one side of the stairs to the other. To measure the total width, use a measuring tape and measure from one side of the stairs to the other. Make sure to measure at the widest point of the stairs.

Step 3: Measure the Tread Depth

The tread depth is the horizontal distance from the front edge to the back edge of each step. To measure the tread depth, use a measuring tape and measure from the front edge of one step to the back edge of the same step. Repeat this process for each step and record the measurements.

Step 4: Measure the Riser Height

The riser height is the vertical distance from the top of one step to the top of the next step. To measure the riser height, use a measuring tape and measure from the top of one step to the top of the next step. Repeat this process for each step and record the measurements.

Step 5: Count the Number of Steps

Counting the number of steps is important in determining the total length of the stairs. To count the number of steps, simply count the number of individual steps from the bottom of the stairs to the top.

Step 6: Calculate the Total Length of the Stairs

To calculate the total length of the stairs, multiply the total number of steps by the tread depth. This will give you the total horizontal distance covered by the stairs.

Step 7: Determine the Staircase Type

There are several different types of staircases, including straight, L-shaped, U-shaped, and spiral. Determining the type of staircase you have will help you determine the best way to measure it.

Step 8: Measure a Straight Staircase

For a straight staircase, simply follow the steps outlined in steps 1-6 to measure the total height, width, tread depth, riser height, number of steps, and total length.

Step 9: Measure an L-Shaped Staircase

For an L-shaped staircase, you’ll need to measure each section of the stairs separately. Follow the steps outlined in steps 1-6 for each section of the stairs and add the measurements together to get the total measurements.

Step 10: Measure a U-Shaped Staircase

For a U-shaped staircase, you’ll need to measure each section of the stairs separately. Follow the steps outlined in steps 1-6 for each section of the stairs and add the measurements together to get the total measurements.

Step 11: Measure a Spiral Staircase

Measuring a spiral staircase can be more complicated than measuring other types of staircases. To measure a spiral staircase, you’ll need to measure the total height and width of the staircase, as well as the width of each individual step.

FAQs

Q: Can I measure stairs without a measuring tape?

A: No, a measuring tape is essential for measuring stairs accurately.

Q: How do I measure stairs if they’re not straight?

A: For stairs that are not straight, such as L-shaped or U-shaped stairs, you’ll need to measure each section of the stairs separately and add the measurements together.

Q: Can I estimate the measurements of stairs?

A: While it’s possible to estimate the measurements of stairs, it’s not recommended. Estimating can lead to inaccurate measurements, which can result in problems during installation.

Conclusion

Measuring stairs correctly is essential for ensuring that your new stairs are the right size and fit perfectly in your space. By following the steps outlined in this guide, you can measure your stairs accurately and with confidence. Remember to take your time and double-check your measurements to avoid costly mistakes.
