Informal Letters Format – When Letters do not follow any particular format while writing is called Informal Letters Format. So can it be considered that letters have either a Formal or Informal structure? Yes and No. Yes, because most of the letters are written with one or the other style in mind. No, because some letters can be written with partial observance of formal or informal styles. For example, an Address Change Letter is basically a Formal letter, however when it is written to a friend it becomes an informal letter as the motive of the letter doesn’t require a style to be followed before it is written. Differentiating features can be that informal letters are personal in nature and length of the letter varies as per the information.
