Pad is typically sold by the square yard in 6 ft rolls, so a room gets many seams and that is fine. Adds 5%. Pad runs up to the tack strip, not over it.

Pad is laid in narrow strips across the room. Figure yards, rolls and strips for your floor.

How it works

Room area plus your extra percentage, ÷ 9 for square yards. Rolls divide by square yards per roll.

Before you order

  • Lay pad strips across the carpet seams, so seams don't stack on top of each other.
  • Check the pad specs your carpet warranty requires.
  • Staple or tape pad seams per the manufacturer.

Common questions

What thickness pad should I get?

Check your carpet warranty, since many specify thickness and density. Thicker is not always better.

Does pad go under the tack strip?

Trim it to the inside edge of the strip so the carpet can grip the tack.
