Step 1 · Step 1: Count Your Treads & Gather Your Tools

Let's start with a quick count of your stair treads. A helpful tip: the number of vertical risers is always one more than the number of horizontal treads you walk on. Once you have your count, gather these essential tools. Using a rigid tape measure (not a flexible sewing one) provides the stability you need for accurate results. A carpenter's square helps confirm true right angles, and a level ensures your measurements aren't skewed. Finally, have some masking tape and a pencil ready to record your findings.
