If you have smaller rooms in your house, you can make them look big by the use of different color schemes and designs that will create the illusion of bigger rooms.
You could begin with this task by bearing the following tips in mind.
All About Arrangement
Make your room appear bigger using color. The first guideline is to use light colors. Light colors reflect light and hence make the room look bigger, while dark colors absorb light, making the room look and feel smaller.
If the colors in your rooms are already dark, try to move the darker colors to a background role while maximizing your neutral white or ivory. For example, paint the walls with a lighter shade, and use dark colors in a border or trim.
Paint your wall and moldings with a lighter color. This will give a 3-D effect. Lighter objects appear closer while darker or shadowed objects appear further away. When you paint your moldings with a lighter color, the walls appear further back, thus making your room appear bigger.
For your fabrics, go for prints that have lighter backgrounds.
In the bedroom, use darker colors for the valance, tiebacks, table scarves, pillows, and bed covers. Use lighter colors for draperies, table covers, and sheets.
Furniture Arrangement
With proper arrangement of furniture you can make your room appear larger. Set some of your larger furniture pieces diagonally. This helps because the longest straight line in any given room is its diagonal. When you place your furniture at an angle, it leads the eye along the longer distance. As a bonus, you often get some additional storage space too!
Angle your bed so that it is coming out of a corner. Usually the corners opposite to the door is the best. This also gives you more available wall space for dressers and bedside tables. If you have a corner in which your furniture looks lost in, place it at an angle. This will help soften the edges of your room.
Instead of choosing a smaller sofa, chair, coffee table, and end tables that crowd your living room, cut back. Use only furniture that is absolutely essential.
Instead of covering the walls with all your pictures, choose a few of the larger pieces and arrange them in a manner that they complement your furniture. The result will pull the attention toward the large furnishings, and away from the actual small size of the room.
