Using the wrong cushion is a common error in how do you lay carpet on stairs. You must use dense carpet padding for stairs no thicker than 3/8 inch.

Cut the Padding Narrow: The padding sits only on the flat tread surface, not wrapping over the nose.
Secure the Padding: Staple the carpet padding for stairs securely. Butt the edge up against the tackless strip without covering the pins.

Step 4: Cutting and Positioning the Carpet Pieces

Two methods exist for laying carpet on stairs: Waterfall and Cap-and-Band.

Measure and Cut: Measure width plus tucking allowance. Measure riser height plus tread depth plus 3 inches for trimming.
Direction of Pile: Ensure the pile runs down the stairs to prevent premature wear.

Step 5: Securing the Stair Tread

Now you execute the practical side of how do you lay carpet on stairs.

Start at the Bottom: Begin at the bottom riser. Staple the top edge against the underside of the first tread nosing.
The Knee Kicker: Pull carpet down over the riser and tread. Position the knee kicker near the back and strike to stretch onto the pins.
Tucking the Crease: Use the stair tool to jam the carpet firmly into the crease. This defines how do you install carpet on stairs correctly.

Step 6: Trimming the Edges and Seams

Side Trimming: Run a trimmer along the wall edge carefully.
Seaming Pieces: For wide stairs, place seams on the vertical riser rather than the tread to avoid foot impact fraying.

Step 7: Repeating the Process

Continue stapling, kicking, and tucking. Laying carpet on stairs is practically second nature, though you'll want to keep a close eye on the alignment. A misstep here could lead to an unsightly pattern shift.
