The Layout of Business Letters
Business letters belong to a formal writing style,so they definitely have their own forms.Generally speaking there are four popular forms listed as follows:
4.1 Full Block Form
In full block form,all typing lines,including those for the date,the inside name and address,the salutation,the subject heading and the complimentary close,begin at the left-hand with no indention in the letter.

4.2 Indented Form
The main feature in this style is that each line of the inside name and address should be indented 2-3 spaces,and the first line of each paragraph should be indented 3-5 spaces.This is a traditionally conservative format of layout.

4.3 Semi-block Form with Indented Paragraphs
In this form,the inside name and address is typed in block form,but the paragraphs forming the body of the letter are all indented 3 or more spaces.

4.4 Modified Block Form
This form is similar to the semi-block form with indented paragraphs with one exception,namely,the first sentence in each paragraph is not indented completely.
