What size rug pad do I need?

The simple rule

Cut the pad about 1 inch shorter than the rug on every side. That makes the pad about 2 inches shorter than the rug in each direction.

For an 8 by 10 foot rug, that means a pad of about 7 feet 10 inches by 9 feet 10 inches.

Why smaller is better

A pad that reaches the edge shows at the sides and lifts the border, which can catch a foot. Leaving an inch lets the rug’s edges taper down to the floor.

Measure the rug, not the label

Handmade rugs are rarely the exact size on the label. Measure the length and width of the rug itself, without the fringe, before you order or cut a pad.

Runners and round rugs

The same 1 inch rule works for runners. For a round rug, cut a circle about 2 inches smaller across than the rug.

Trimming a pad at home

Lay the rug face down, place the pad on top and mark a line about 1 inch in from the rug’s edge. Cut with sharp scissors or a utility knife. Many shops will also cut a pad to size for you.
