The main difference between a single-wide and double-wide manufactured home is space. A single-wide home is typically 14 – 18 feet wide and 52 – 80 feet long. In comparison, a double-wide home is 28 – 36 feet wide and 52 – 80 feet long. You’ll typically pay about 25% less per square foot for a single-wide home than you would for a double-wide.
