Step 2 · Measure Your Straight Treads with Precision

Now, for the straight portions of your L-shaped staircase, let's get those measurements. You'll need the width and depth of each individual step. A crucial tip: Always measure the tread surface itself, from edge to edge, not from the wall to the wall. Why? Because the walls around corners often aren't perfectly square, and this ensures a snug fit. Don't forget to account for any existing trim or the rounded front edge of the step (the 'overhang'). We recommend numbering each tread with a piece of painter's tape as you go—this simple trick prevents mix-ups and makes installation a breeze.
