You can play around with the area’s rug size, which can directly affect people’s perception of the room’s actual size. If you decide on a small rug, the room will look smaller, too, and vice versa. The main purpose of the rug is to build imaginary boundaries, which visually separate different areas of the room that serve various purposes. For example,the area rug in your living room would separate the lounge area. And with furniture’s legs stepping at the edge of the rug, you would set yourselves up a nice area rug.
