Stair Tread Measurement

Using a rigid tape measure, press one end firmly against the vertical panel at the back of the step (this is called the 'riser'). Extend the tape straight across the flat part of the step and over the rounded front edge, known as the 'nosing'. For a perfect fit, it's crucial that your measurement captures the bare wood only. Be sure not to measure over old paint drips, leftover adhesive, or remnants of old carpet, as this can throw off the final fit. Write down this depth measurement for your first step.

Measure the width of your step from side to side, keeping the tape measure parallel to the back riser. If your stairs run between two walls, measure the full wall-to-wall distance. If one or both sides are open, simply measure the full width of the wood. A popular, design-conscious choice is to leave a small border of wood visible on each side of the carpet tread. For example, on a 36-inch wide stair, a 34-inch tread leaves a lovely 1-inch border on each side, framing the tread beautifully. Record this width measurement for the step.

In your notebook, create a simple list from top to bottom, recording the width and depth for each step. Don't be surprised if the numbers vary slightly—it's common, especially in older homes! If you find a step with unique dimensions, place a small piece of masking tape on its riser and number it to match your notes. This simple organization provides peace of mind. If you're ordering custom-made treads, taking a quick photo of each unique step with your notes can be incredibly helpful. Finally, take a moment to double-check all your numbers. A few extra seconds here ensures a flawless result you'll be proud of.
