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.
Entrances. Most people think area rugs are too large for an entrance but they are available in the smaller sizes. So whether you have a grand entrance or a smaller entrance you should consider making a decor statement where people enter. You could place a beautiful oval braided rug at your entrance or a bold rectangular rug. Make it blend or stand out. Your choice. An area rug at your entrance also has some function use as well. The worst thing for your carpets is oil dirt and sand. Even a clean pair of shoes will track particles onto the carpet. Using an area rug will help reduce what gets tracked because it will act as a catcher. If you have a tiled or linoleum entrance it will also keep it looking cleaner as the rug can pick up the dirt or mud off of shoes and it's easily cleaner up with a vacuum.
Rug composition. Rugs are made of many different materials. Many of them today thanks to the development of synthetic fibers are inexpensive to own. Cheap area rugs can be used in spaces where there is much more traffic and where the rug may need to be replaced occasionally. Cheap area rugs do not need to look cheap. The man made materials often have more variety than more expensive Persian rugs. Persian rugs are known for their beauty and durability but may be beyond the budget of many homeowners. Discount rugs are often made of synthetic fiber which repels water better than Persian rugs so may be more appropriate as kitchen rugs or bathroom rugs.
