When you see rugs hanging in a showroom, keep in mind that they look a lot bigger than when they are on the floor. Therefore, it can be tricky to guess the rug size you need just by looking at a room or a rug. You need to actually measure the size of the space, and know how much of the floor you want covered, as well as know which pieces of furniture you want placed on the area rug. These illustrations should help you decide:
For large bedrooms, one approach is to have an area rug that covers most of the floor space – one that can accommodate having all furniture on it.
An alternate approach for large bedrooms is to have the rug stop right before the night tables.
For small bedrooms, or if you have a smaller rug you’d like to use, try placing it under the middle of the bed so that it comes out a few feet from under the end and the sides of the bed.
