A 150-square-foot space is around ten feet broad by fifteen feet long. This may appear small to North Americans since the average living room is roughly 16 feet by 16 feet, or 256 square feet, according to Dimensions Info. However, this amounts to about one square foot of living space for each inch of floor space. In terms of area, the 150-square-foot space is about 0.5 square meters. This is a bit more than half an acre. A typical suburban back yard is about 50 feet by 100 feet, or 500 square feet, so the ratio between house and yard is slightly less than 2:1. There are 830 inches in a meter, so 1 square meter = 0.8291667 acres. 150 square feet = 14.7 square feet per person So, if you were to share this space with another person, they would need about 15 percent more room than you do. This assumes that you are not big people who take up a lot of space. The majority of us average-size humans can comfortably fit into a space about 30 percent larger than we do ourselves. If your neighbor had access to your bathroom too, they would need about 19 percent more space than you do.
