Rug Pad Guide
What size rug pad do you need?
Start with the rug's actual dimensions, then choose a pad that sits inside the rug edge according to the pad's documented sizing guidance.
Step-by-step
Measure the rug, not the label
Listed rug sizes can be nominal. Measure the actual width and length, then write both dimensions in feet and inches.
Read the pad's sizing guidance
Do not assume one inset fits every construction. Use the fit rule on the exact pad product page and confirm that its finished dimensions sit inside the rug edge.
Compare stock and custom dimensions
Use a stock size when its documented dimensions fit your rug. If none does, compare the rectangular dimensions offered by the custom area and custom runner configurators.
Confirm both dimensions
Check width and length together before checkout. A familiar size name is not a substitute for the actual measurements shown for the selected option.
Treat unusual shapes separately
For a round rug, angled area, or notch, choose a product designed for that shape or confirm that the exact pad's instructions approve trimming before cutting it.
Follow installation guidance
Use only the installation method documented for the pad and floor. Do not add tape, adhesive, cleaner, or another layer unless both product and flooring guidance approve it.
Common mistakes to avoid
- Ordering from the rug's nominal size without measuring its actual width and length.
- Measuring the room instead of the rug — the pad's job is to sit under the rug, not to fill the floor.
- Assuming a pad can be trimmed or used with a floor finish before checking the exact product guidance.
Find the pad that fits
Compare each pad's documented material, thickness, available sizes, and floor guidance. Choose a pre-made size or configure a custom option where offered.
Choose or enter a size on the product page, then add your ZIP code for current delivery timing.
Shop rug padsFrequently asked
Should a rug pad be the same size as the rug?
The pad should generally sit inside the rug edge, but the exact inset depends on the product. Measure the rug and follow the sizing rule shown for the pad you choose.
What if my rug is an odd size?
Compare the dimensions offered by custom pad products. Trim a pad at home only when that exact product's instructions say the material may be cut and explain how to do it.
Does the sizing rule change for runners?
Measure the runner's actual width and length, then use the runner pad configurator and its fit guidance. Confirm the displayed dimensions before ordering a custom-cut pad.
What thickness should the pad be?
Choose from the thicknesses documented on the product page. Compare the combined rug-and-pad height with door swings, furniture, and the intended placement.

How thick should a rug pad be?
There is no universal best thickness. Start with the profile documented for the pad, then compare the combined rug-and-pad height with the way the room works.

How do you choose a rug pad for hardwood floors?
Compatibility depends on the exact pad backing and hardwood finish. Use the pad's Product Details and your flooring manufacturer's instructions together.
