A single bedroom must have a minimum floor space of 7.0 square metres, or 75.35 square feet, and a minimum width of 2.15 metres, or 7 feet 1 inch. A double bedroom (or twin) must be 11 square metres (118.41 square feet) in size and 2.55 metres in breadth (or 8 feet 5 inches). The actual area of a room is determined by its dimensions. For example, if a room has a length of 7 meters and a height of 4.5 meters, then it is approximately 50 square meters (5,152 square feet) in area. The math is easy to do in your head, but if you're like most people, you probably need help with numbers this big! A convenient way to measure your room is with millimeters. If the measurements of your room are listed as 300 mm x 200 mm, for example, then it is 3 meters long and 2.5 meters wide. Most rooms are larger than they appear, so that doesn't matter too much. But if you want to maximize the use of your space, consider these tips: * Use furniture that can be pushed against walls to create more walking room. This will make it easier for guests to enter and leave your home without knocking things over. * Install doorways with wider openings to allow more light into dark bedrooms. * Put large pieces of art on the wall opposite the bed; this will help make the room look bigger.
