measure stairs for treads

Getting an accurate count is the first step toward a successful installation. Begin by counting the number of horizontal surfaces you step on—these are your treads. A quick tip: you'll always have one more vertical riser than you have treads. Then, assemble your tools. For a professional result, you'll need a rigid tape measure, a carpenter's square, a level, some masking tape, and a pencil and paper to record your dimensions.

Now, let's measure the depth, also known as the 'run,' for each individual tread. Place the end of your tape measure firmly against the vertical riser at the back. Extend the tape straight across the flat part of the tread and over the rounded front edge, often called the 'nosing.' It is critical that your tape measure remains flat and level. For true accuracy, never measure over existing carpet, vinyl, or old adhesive, as this will prevent your new treads from sitting securely. Record the depth for each step. While standard tread depths are often 10 to 11 inches, your home is unique—always trust your own measurements.

Next, determine the width of each tread. Stretch your tape measure across the tread, keeping it parallel to the back riser. If your staircase is enclosed by walls, measure directly from wall to wall. If one side is open, simply measure the full width of the wooden tread. For a classic, bordered aesthetic, many homeowners choose a tread width that leaves about 1 inch of wood visible on each side. For example, a 36-inch wide staircase would perfectly accommodate a 34-inch wide tread. Most residential stairs are between 36 and 42 inches wide, but measuring yours will guarantee a perfect, custom-made to fit result.

Measure twice, order once! This simple rule is the key to a DIY-friendly project without the stress. As you measure, write down the width and depth for each step, labeling them clearly (e.g., 'Step 1, Step 2'). If you discover a step with unique dimensions—a common occurrence in older homes—mark it with a piece of masking tape and a number. For custom orders, taking a quick photo of each uniquely-sized step along with its written measurements is incredibly helpful. Before you finalize anything, double-check all your numbers. Even a quarter-inch difference can affect the fit, compromising the safety and style you're looking for. This attention to detail is The Oak Valley Difference.
