Our distinctive louver size options can reveal a California or Plantation look. California shutters are known for its smaller louver size of 2 1/2”, and a more traditional look. When shutters are fully opened with 2 1/2” louvers, more privacy is attained. Plantation shutters are primarily made with 3 1/2” louvers and provide a contemporary, modern appeal. When shutters are fully opened with 3 1/2” louvers they provide more than 50% greater visibility than 2 1/2” louvers.
