Rooms-Sized rugs: Can be cut to fit any room. Any length of carpet can be purchased in standard widths. They cover a room within about 3-9 inches of its border. For example, to cover the floor of a room of 11' x 16', a standard finished 9' x 12' rug would be small; a 12' x 15' would be too wide. A wise size would be 10' x 15' rug. The rug would then have a 6" border or floor area seen around the edges. Because rugs usually stretch on the floor. They offer the same decorative advantages as wall-to-wall carpet and no installation and easy to move.
Area Spot-rugs: Cover only a small area of the floor. They may be of a solid color, and usually they are bold pattern. They are useful to change the proportions of a room, to define areas within a room or to give a room a splash of color, warmth and design. There are two kinds of area rugs
Accent rugsand scatter: Resemble area rugs but are usually more dramatic in pattern, shape, texture and color. They are often used for decorative effects. Oriental hooked and braided rugs are usually included as accent rugs even though some of them are of room sizes. These are small and vivid, and can be used to have contrast and emphasis. Some of them are the prettiest, inexpensive and exquisite.
Scatter rugs: are smaller rugs that add spots of color and texture to make a bare floor look interesting. They are often used to protect areas that are subject to heavy wear or soiling. They are inexpensive and can easily be washed. Accent and scatter rugs are ideal to bringing a color and texture to a situation to relive the dullness of the flooring such as concrete flooring.
