Curved Stair Measurement
About This Project
Winding or curved staircases add architectural beauty to a home, but measuring them for stair treads can feel intimidating. Don't worry—we're here to help! Getting precise measurements is the crucial first step to ensuring your custom-made treads fit perfectly, providing the safety and style your family deserves. This guide makes it easy to measure each unique step, so you can confidently order treads that elevate your staircase with a flawless, professional finish.
Steps
Gather Your Tools & Count Your Steps
5 minutesLet's start your project by getting organized. First, count the total number of stair treads you'll be covering. A fun fact: you'll always have one more riser (the vertical part) than you have treads (the part you step on). Next, gather your tools for success: a rigid tape measure for true, accurate readings, a carpenter's square to check your angles, a level to ensure everything is straight, some masking tape for marking, and a trusty pencil.

10 minutesLet's measure the depth, or 'run,' of each step. Place your tape measure firmly against the vertical riser at the back. Extend it straight across the surface to the very tip of the front edge, which is called the 'nosing.' Keeping the tape measure flat and level is key to an accurate measurement. Important Safety Note: Always measure the bare wood. Measuring on top of old carpet, padding, or leftover adhesive will throw off your dimensions and prevent a secure, safe fit for your new treads.

10 minutesWith depth recorded, it's time for width. Run your tape measure along the front edge of the tread, parallel to the riser. If your stairs are between two walls, measure wall-to-wall. If one or both sides are open, measure the full width of the wooden step. For that classic, professionally-finished look that allows your beautiful wood to frame the tread, we recommend leaving about a 1-inch border on each side. This means your custom tread width would be 2 inches less than the total stair width, a design choice that brings warmth and elegance to your home.

15 minutesThis is where it all comes together for a perfect fit! Carefully write down the width and depth for each step in a notebook. Use your masking tape to label each stair with a number that corresponds to your notes—this is vital since each step on a curved staircase can be different. For the ultimate peace of mind when ordering your custom-made treads, we strongly recommend taking a clear photo of each step next to its measurements. Before you're done, double-check everything.
