A good carpet pad sits between your carpet and the subfloor, reducing friction that would otherwise wear out fibers prematurely. It also absorbs impact and noise, keeps floorboards from scuffing, and makes each step feel softer. If you’re laying new carpet, spending a little extra on quality padding is one of the easiest ways to boost comfort and stretch the life of your investment.

The amount of carpet padding you need depends on the size of the room you're carpeting. Measure the length and width of the room, and then multiply those figures to determine the square footage. Then, use the square footage to determine how much carpet pad you need to cover the room. It’s a good idea to budget for 10% more overage than your calculations in case of mishaps during the installation.

The lifespan of carpet padding depends on the material used and the level of foot traffic it endures. Flat rubber padding can last for up to 20 years, whereas prime foam often needs to be replaced within five years. Worn padding affects your carpet’s comfort and support, so regular inspections help determine when it’s time for an upgrade.

Replace your carpet padding as soon as you notice it losing its supportive function. When the carpet begins to exhibit lumps, visible dips, or a crinkly sound underfoot, the pad no longer provides the firmness your flooring requires. These signs indicate that the cushioning capacity is compromised, which can affect both safety and comfort. Upgrading the padding at this stage helps maintain the carpet’s performance, preserves its appearance, and extends its overall lifespan.

Thicker carpet padding is not inherently better than thinner options. The optimal padding quality is determined by the type of carpet and the level of foot traffic in the area. In high-traffic spaces, a thinner yet denser pad delivers the stability and support your floor requires, while in low-traffic areas, a slightly thicker pad may enhance comfort. Select padding that suits the requirements of each space, ensuring both enhanced durability and a consistently pleasing underfoot feel.
