1. Transform your walls. Magically make your walls grow taller by using vertical or horizontal stripes using paint or wallpaper. Horizontal stripes will visually widen a small narrow room. Vertical stripes will make a low ceiling seem taller. Mirror a wall that opposes a window and double your light. Avoid tiny geometric prints; they will be too busy and chaotic in a small space.
2. Make friends with scale and proportion. Like Goldie Locks looking for the right bed, one was too big, one too small, and finally one was just right, furniture needs to be just right in a small room. A large couch in a small area can overtake the space, while a small couch will seem dwarfed. Mix large pieces along with smaller pieces for balance. Consider using a large bookcase or sideboard along a wall. Slipper chairs are great options as well as armless chairs tucked into a corner.
3. Keep your wall, ceiling and floor in the same color family.Your eye naturally follows the floor up to the wall and then to the ceiling. By keeping the three surfaces in the same color family the space will visually open up as they recede creating the illusion of more space.
4. Consider traffic patterns. So now you have the right scale furniture, but you want to move around the space easily. A fabulous trick is to float your furniture in the space. Move your couch and chairs away from the wall. This will create depth in the space. You want to see a fair amount of the floor. The more of the floor that can be seen the larger the room will appear. Next, ground your furniture with an area rug in the same color tones as the flooring.
