Someone told me that decorators have a general rule for the size area rug you need for a room. It is something about a certain number of feet of exposed floor around the perimeter of a room. Does anyone know about this? Thanks.
it depends on what else is in the room but i would go with a 6x8 if it is going to be a dinning room.
There's no perfect answer. You have to decide if you want to have furniture on the carpet, completely off the carpet or partially on the carpet. Then decide the size. After that you can either look for a pre made rug or have one made.
There really isn't such a rule. An area rug is used to anchor the furniture arrangement in a room and as a sound barrier for hard surface flooring. I would look at how the furniture is arranged a choose a size that optically connects the furniture to the rug. More often than not, people choose a rug that is too small and out of scale with the furniture. A 6 x 8 may be optimal for the dimensions of the room if it serves the scale of the furniture and the amount of furniture in the room.
Generally (not a hard rule) leave about 1ft- 3ft if you are doing a rug for the whole room. A 6x9 rug is fine for 10x 10 room. It is easy to find for a ready made rug in retail about 6x9. I more expensive but good choice is an 8x8 square if you can find it. 5x8 would be ok but I would say don't go any smaller. Put the furniture on the rug you get, rather than pushed all against the wall.
