Step 7 · Cut Treads

Cut the treads from your chosen lumber. The dimensions of each tread will be determined by your layout. For alternating tread stairs, the treads may have different depths on each side to accommodate the alternating stepping pattern. Ensure the cuts are square and the treads will fit snugly into the stringer notches.
