A 200-square-foot area is about equivalent to a one-car garage. In other words, with some wiggle room, the average automobile might fit into a 200-square-foot area. Consider a 100-square-foot space smaller than a bedroom. A 100 square foot area is rather tiny. You would need to be very careful not to block the only open doorway with any part of your body or an object. The term "200 square feet" may also apply to the amount of floor space in a room. For example, a room with a width of 10 feet and a length of 20 feet has a total area of 300 square feet. The room would therefore have enough space for eight 5-foot by 8-foot sheets of paper. In terms of volume, the number 100 followed by three zeros represents a large quantity of material. So, a room that's 100 square feet is quite small compared to another room that's 100 feet by 100 feet. That second room would take up 1,000 square feet or more. It's important to remember that measurements such as "100 square feet" are approximations. Some rooms that appear small on paper can actually be quite spacious if you consider the dimensions of each sheet of paper that could possibly fit into the room. Other factors such as furniture size and placement play a role in determining how much space a room takes up. However, for estimating purposes, these numbers serve as good guidelines.
