If you have a small room and are looking for ways to make it feel larger, there are several different ways to do it.
Scale Furniture: The size of your furniture should be appropriate for the size of the room. For instance, a large overstuffed couch may crowd a small room. On the other hand, a smaller piece might feel like it's floating in a large room.
Paint Ceiling Lighter: Painting the ceiling white, or a lighter shade of the color on the walls, gives a feeling of airiness to the room.
Framed mirror: A large framed mirror hanging in the space can add a feeling of depth to the room.
Identify a focal point: Call attention to a focal point in the room, such as a fireplace. Or, if you have a beautiful window, frame it so that the outdoors become the focal point. This helps create the illusion of more space.
