Rug placement most probably is one of the factors that you might want to consider first in selecting a rug. It is important to know where the rug is going to be placed. As you consider the placement of the rug the other factors will follow: such as color materials and size.
Renter Choices. If you are renting you certainly don't want to spend your money on carpets. Whether your carpets are worn or they just don't fit your decor you can give your apartment a facelift for a minimal amount of money. Then when you move you can roll up your area carpet and take it with you to your new home. There's no point in begging the landlord to change the carpets because unless they are totally shot chances are you won't get your wish. And even if you were willing to change them yourself your landlord might not approve but you'll get no arguments about putting down an area rug. In fact you don't even need permission. You can use one or more area rugs throughout your apartment to add your own personal touch and finish your home decor.
Hallway Rugs. Depending on the size of the hallways in your home you will likely need a long narrow area rug - or runner - for this space. In order to achieve a balanced look and find the right size rug for your hallway keep in mind that the rug you select should be two to four inches narrower than the width of your hallway and 18 to 24 inches shorter than your hallway's total length.
