What is a Formal Letter?

A formal letter is a written communication to or from an individual, company, institution, or organization for information, or a request for action in a predefined format with an appropriate choice of words. The language in a formal letter is expected to maintain the decorum of tone and voice.

Difference Between a Formal Letter and an Informal One

Whereas an informal letter communicates in a personal way, a formal letter informs or requests the recipient in an official manner.

There is no hard and fast format for an informal letter. The writer can choose any writing style and tone he likes. However, a formal letter is generally written in a prescribed format that renders it readable, comprehensive and impressive. For example, the font style and size are generally maintained Times New Roman, 12 but there is no such thing for an informal letter.

The language in a formal letter is limited to sound neither harsh nor flattering. It maintains a certain level of decency. On the contrary, you may choose to show your emotions in an informal letter to the extent you decide.
