The ideal size of an area rug should be big enough to go under furniture while still remaining visible and providing space to walk on. That means the rug size will vary depending on the room size and type of room.
A living room area rug should be big enough for all of your furniture to fit on top or at least have the front legs on the rug. Aim for a length that provides six to eight inches of space on both sides of your longest couch.
If your living room is big enough for all of your furniture to fit on a large living room rug, remember to leave about 10 to 20 inches around the rug for walking. This will help to create a defined space and ensure the rug isn’t too big for the room.
You can also use a smaller living room rug centered between the couches under your coffee table, but just make sure the space between the rug and the couches isn’t more than six inches or it may look too small.
When it comes to bedroom rugs, the rug size will depend on your bed size. A large area rug that fits beneath the entire bed and nightstands is a simple solution. Or you can place the rug perpendicular to the bed so that it stops a few inches short of the nightstand, but still allows you to have a soft surface for your feet and extends past the foot of the bed.
Dining room rug size is also important. Choose one that fully fits beneath your table and chairs even when pulled out.
