What Is the Average Square Footage for Triple-Wide Trailer Homes?

The average size of a triple-wide mobile home is 1,900 to 2,500 square feet, about 50 percent bigger than a double-wide and two to three times bigger than a single-wide, reports CostEvaluation.com. The size of a particular model depends on the style, amenities and manufacturer.
