Here you will find some generally accepted guidelines for selecting an area rug that will fit your space well and perfectly accent your living area, but do keep in mind that personal preferences should trump any type of rules put forth by the rug industry or interior designers.
Just about any home can be improved with the use of area rugs of good design and quality. These bound carpets come in many sizes from 2 feet by 3 feet to room size or common sizes like 6 foot by 9 feet or 4 feet by 6 feet. They come round, square, rectangular, oval and in runners for steps and hallways. Wall to wall carpet in 12 and 15 foot goods can be cut and bound into area rugs or the makers can weave or tuft these small carpets as the end result. Where ever you need a little break from hard surface flooring, or to cover a worn area in carpet, consider adding an area rug.
Remember to bear in mind what part of the room the rug is going to be positioned; whether it is placed on doorways or near air vents, etc. This is because some rugs are too thick or some doors just don't have enough space allotted for an area rug; this would either cause the door to not open or allow the rug to slide and shift every time the door opens. Also there are rugs that can't withstand the heat from air vents. Make sure you pick a rug's material carefully based on the placement of the rug.
