Winder Step Measurement
About This Project
Winder steps, the wedge-shaped treads that navigate turns in a staircase, can seem tricky to measure for a DIY stair remodel. But getting it right is the key to a perfect, custom-made fit that provides both safety and style. This simple guide will walk you through an accurate process to measure your winder steps for custom treads from Oak Valley Designs. We'll show you how to find the average width and proper depth, while also reviewing important safety codes to give your family peace of mind.
Steps
First, Pinpoint Your Winder Steps
15 minutesLook for the steps that create the turn or curve in your staircase—these are your winder steps. They'll have one side that's narrower than the other, unlike your standard rectangular treads. Getting accurate measurements for each one is the first step toward a beautiful and secure staircase that you can be proud of. This is where safety meets style.

10 minutesGrab your tape measure. For every single winder step, you'll take two key width measurements: one along the short, inner edge and one along the long, outer edge. Write these down for each step—they are the foundation for creating a tread that fits flawlessly and elevates your staircase.

5 minutesNow for some simple math that makes all the difference. For each winder step, add the narrow edge measurement to the wide edge measurement, then divide that sum by 2. This result is the 'average width,' the number we'll use to create a beautifully proportioned, custom-made tread. It's also a good idea to note the smallest width you measured on each step; this serves as a helpful reference.

15 minutesSafety is paramount, especially for families with children or pets. First, measure the depth of the step from the front edge (the nose) to the back at its deepest part. Now, let's verify two critical safety standards. The narrowest part of your step must be at least 6 inches wide. Next, find the 'walk line'—an imaginary path where people naturally step, about 12 inches out from the narrow edge. The depth here must be at least 10 inches to provide a secure foothold. Finally, the difference in depth at this walk line between your largest and smallest winder treads should not be more than ⅜ inch. These checks ensure your stairs aren't just beautiful, but built for everyday life.

10 minutesYou've done the hard part! Now, gather all your notes: the average width, smallest width, and depth for each unique winder step. Snap a few clear photos of your staircase turn from different angles. Providing us with this complete set of information allows us to craft your treads with precision, ensuring they are custom-made to fit perfectly. You're just one step away from a safer, more stylish staircase that brings warmth and elegance to your home.
