measure stairs

Let's begin! First, get an accurate count of the individual stair treads you'll be transforming. A helpful tip: you'll always have one more riser (the vertical part) than you have treads (the flat part you step on). Once you have your count, gather your tools. You'll want a rigid tape measure for accuracy, a carpenter's square to check for true right angles, a level to ensure your measurements aren't skewed, some masking tape for labeling, and a pencil to jot everything down.

For each stair, place the end of your tape measure firmly against the riser at the back. Extend the tape straight across the flat surface until you reach the outermost edge of the tread's nosing. It's critical to keep the tape measure perfectly flat and level for an accurate reading. Be sure you are measuring the bare wood, not on top of old carpet or leftover adhesive, as this can throw off your dimensions and prevent a perfect fit. Record the depth for each step as you go.

Now, let's measure the width. Run your tape measure from one side of the tread to the other, keeping it parallel to the back riser. If your stairs are enclosed, measure from wall to wall. If one or both sides are open, measure from the finished edge of the wood. Many homeowners love the look of a 1-inch border of exposed wood on either side of the tread, which beautifully frames the staircase. If you want this style, your final tread width will be about 2 inches less than your total measured width.

This is where it all comes together. Meticulously write down the width and depth for each step, labeling them clearly (e.g., 'Step 1,' 'Step 2'). Don't be surprised if the measurements aren't all identical, especially in older homes—it's part of their character! Use masking tape to label any steps with unique dimensions. Taking a quick photo of each step is also a great idea for your records. Following the old carpenter's rule—'measure twice, cut once'—ensures you'll have all the right information to order treads that are custom-made to fit, giving you peace of mind and a flawless result.
