How to tell what size rug pad you need

There’s nothing better to an interior design enthusiast than finding the right piece to tie the whole look together. When you find the right high-quality area rug for your space, you just know.

Maybe it’s a low profile flat weave for your entryway, hallway or other high-traffic areas. It could be a plush shag rug to rest your feet on and protect your hardwood floors in your living room.

Once it finally arrives and is placed in the perfect spot, you’ll want to ensure that you take steps to extend the life of your new area rug. Bunching and shifting not only create a tripping hazard but will cause excessive wear and tear that will have your rug looking old before its time.

The best way to keep both small rugs and large rugs firmly in place and looking like new is to invest in the right type of rug pad.

However, not just any rug pad will do. You’ll need to select the right size rug pad for the job.

Let’s take a look at how to size a rug pad for your area rug, steps you can take to resize a rug pad yourself, and which ones are the best for your home.

How do you size a rug pad for an area rug?

Whether you have laminate or hardwood floors, choosing the right area rug pad to place beneath your favorite rug offers many benefits.

  • Non-Skid Grip: Rug pads with a rubber backing easily grip your floors and lock your area rug in place. Bonus: if you choose a natural rubber rug pad, they won’t react with your floors and cause staining.
  • Comfortable Cushioning: Thicker pads, especially ones made with felt or memory foam, offer luxurious cushioning underfoot and make any hard surface beneath your area rug instantly more comfortable.
  • Floor Protection: The proper rug pad will protect any type of flooring, including vinyl, carpeting, laminate, and hardwood floors. Choose eco-friendly materials to ensure the rug pad doesn’t deteriorate over time and cause a chemical reaction that will ruin your floors.
  • Extends The Life Of Your Rug: Most area rugs, especially wool rugs, need a rug pad to help hold down the edges of the rug. By keeping your area rug in place, rug pads prevent excessive wear and tear that cause the rug backings to be compromised, leading to a worn and unsightly carpet.
  • Sound Muffling: Whether you are a homeowner working from home or an apartment dweller trying to avoid irking your downstairs neighbors, the cushioning in a rug pad will help dampen the sounds of your music, conversations, and footsteps.
  • Insulation: A solid rug pad will help block drafts and increase the efficiency of your home’s heating and cooling.

No matter what rug size you are working with, you’ll need to follow some basic steps to ensure the rug pad you choose is the correct measurements.

A common misconception is that you should install a rug pad that has measurements identical to your area rug. If the dimensions of the two products match, the rug pad will be less effective and will peek out from the edges of your rug, ruining the aesthetic.

To choose the correct rug pad size, you’ll need to follow these steps.

  1. Use a measuring tape to measure the length and width of the rug Note: Do not include the decorative ends, like tassels. Only the rug itself.
  2. Subtract two inches from both the length and width of the rug (Subtract three inches for thicker rugs).
  3. Use these measurements to select your rug pad size.

For example, if you are selecting a rug pad for an area rug that measures 6 feet by 9 feet, you will need a 5' 10" x 8' 10" rug pad. Rug pads that measure 5 x 7 will work well with an area rug that measures 5' 2" x 7' 2".

For thicker pads underneath large rugs measuring 10 x 13 or more, you will want a slightly larger overhang, so subtract 2.5-3 inches from your rug’s measurements when choosing the rug pad size.

Sometimes you will need to resize a rug pad yourself to get the best fit. Let’s take a look at how you can resize your rug pad for a perfect fit beneath any area rug.

The cutting utensil you use will depend on the material and thickness of your rug pad.

Thin rug pads: Sharp Scissors Or Shears.

Thick rug pads: A Box Cutter Or Utility Knife

Memory foam rug pads: Foam Cutters

What rug pad works best for a runner rug?

Because runners are typically placed in high-traffic areas of your home, like hallways, entryways, and mudrooms, you need a rug pad that offers solid grip to prevent slips and skids.

Opt for a natural rubber rug pad that is easy to clean, mold and mildew resistant, and most importantly, will anchor your runner firmly in place.

Can cheap rug pads ruin my expensive floors?

Yes! Cheap rug pads will ruin your expensive floors because they are made from synthetic materials, like PVC. These materials break down and flake. This not only makes a mess but can cause the rug pad to react with your floors, causing expensive damage.

Not only that, cheap rug pads are often sprayed with adhesives, which cause the pad to stick to both your area rug and floors. This will leave residue behind that is difficult to remove and may cause a chemical reaction with some flooring finishes.

Always invest in a high-quality rug pad made from all-natural, eco-friendly materials, like jute, natural rubber, and felt.
