Width

• The width of a single-wide trailer varies, but is commonly 12 to 14 feet wide. These dimensions do not include sections that can be extended when the trailer is not in use.
  
  

Length

• The single-wide trailer can extend from 40 to 70 feet in length, although trailers of roughly 60 feet are common.
  
  

Square Footage

• A single-wide trailer ranges in area from 480 square feet to 980 square feet--again, without including any extensions or pop-out sections.
  
  

Single Wide Uses

• In municipalities where it is legal to do so, a single-wide trailer can be used as a residence, an office space or a storage space. Single-wide trailers can be treated by zoning officials as buildings due to their size.
  
  

Combining Single Wide Trailers

• Two single-wide trailers that are attached create a double-wide trailer, which is generally 24 to 28 feet wide. These are considered more static structures and zoned similarly to homes.
