Big vs. Small

The size of a room or the features within it dictates basic interior design elements. If you have a small office, for example, an antique roll top desk smack in the middle of room will make the room feel crowded. A better choice might be a more "airy" piece of furniture.
The proper use of scale applies to paint and fabrics as well. While rooms painted white appear larger, that doesn’t mean all small rooms should be white. A tiny nursery can be very intimate in forest green – but adding a wallpaper border of giant teddy bears may be a bit too much, making the room appear off-balance.
The general rule is larger rooms accommodate bigger furniture and patterns well, just as smaller rooms work better with less furniture and reduced prints.
