A rug goes a long way in making a room more aesthetically appealing. But the rug pad does the real work.
Despite being barely visible, this thin layer of material does a lot of heavy lifting. It prevents you from slipping, or furniture from damaging your floors. It blocks sound and improves insulation, and provides soft feel underneath your feet. It’s a crucial protective layer that extends the lifespan of a rug.
But what is a rug pad supposed to be made of? How do you choose the right rug pad according to your floor? How do you measure the correct rug pad size? We simplify the process and take all the guesswork out for you. Just contact us, and we’ll recommend the best rug pads for your needs.
Confused? This guide on choosing the right rug pad size should give you some clarity.
Should Rug Pad be Same Size as Rug?
Does a rug pad need to be the exact size as your rug? No.
When choosing the right rug pad size, always remember that the pad should be smaller than the rug. It should fit snugly underneath, so its edges are neatly hidden, and the rug is naturally tapering towards the floor. There are three reasons for this:
- It prevents common tripping hazards, such as a shoe clipping the edge.
- It protects your rug from curling, a common sign of premature wear.
- It keeps the rug looking beautiful without the pad showing from the sides.
So it must be shorter. But by how much? Let’s dive a bit more into the specifics of how to size a rug pad:
-
How Much Smaller Should Rug Pad Be?
The experts of Thomas Rug Cleaning stress that a rug pad should be at least one inch shorter than the rug on each side (or along the radius, in case of circular rugs).
So, for example: If you have a rug that measures 8 feet x 10 feet, you would need a rug pad that is around 7 feet and 10 inches x 9 feet and 10 inches. One inch less on each side. This subtle difference is enough to keep the pad concealed.
If the pad is properly cut to match the shape of your rug, it will help prevent major tripping hazards.
-
How Thick Should a Rug Pad Be?
When it comes to thickness, too, there is a huge variance. Rug pads can be anywhere from 1/16th of an inch thick to half an inch thick. Here’s how to pick one:
Thicker Rug Pads (¼ – ½ inch)
Thicker rug pads provide better cushioning and feel amazing underfoot. Beyond the luxurious comfort they offer, they also help prevent uneven wear and extend the life of your rug.
Thinner Rug Pads (1/16 – 1/8 inch or less)
For a low-profile, flush feel against the floor, a thinner rug pad will keep your rug in place, prevent buckling, and reduce trip hazards. It’s also ideal for areas with door clearance—no need to shave down your doors.

Measuring Rug For Rug Pad: Step-By-Step Guide
The best way to cut a rug pad to size is to place the rug on top of the padding and trim around it. Since most handmade rugs aren’t perfectly even, this method ensures the best fit. However, if that’s not an option, here are our recommended steps:
Don’t rely solely on manufacturer specifications as they may not be precise. Instead:
- Step 1: Lay your rug completely flat on the floor, smoothing out any wrinkles or curled edges that might affect your measurements.
- Step 2: Use a tape measure to note down the exact length and width of your rug in the middle. For round rugs, measure the diameter. Ignore any additional frills along the edges of your rug, such as tassels. Do not include the fringe in this measurement.
- Step 3: Calculate the rug pad size by subtracting 2 inches from the total size. For an 8’x10’ foot rug, your pad should measure approximately 7’10” x 9’10”.
Next time your rug is in for cleaning, we’ll be happy to provide a perfectly cut pad to size—saving you the hassle of trimming it yourself.
