Step 3 · Determine Depth and Ensure Safety with Code Verification

For each winder step, measure the depth from the very front edge to the back edge at its deepest point, ensuring your future tread will offer full coverage. After establishing the depth, it's absolutely essential to verify critical code dimensions for stairSafety and walkability. Confirm that the narrowest point of the winder tread measures a minimum of 6 inches. Next, visualize an imaginary 'walk line' situated 12 inches in from the narrow edge of the tread; measure the depth of the tread along this specific line, ensuring it is at least 10 inches. To maintain consistency and safety, also check that the largest tread depth at the walk line doesn't exceed the smallest tread depth at the walk line by more than ⅜ inch. Lastly, for overall peace of mind, verify that the riser height (the vertical space between steps) does not exceed 7¾ inches. These checks are vital for families with children or pets and ensure your stairs are built for everyday life.
