Left flush justification is the format of this paragraph. The spaces between the words are all the same, and the reader can move from one line to the next with little or no problem.
Avoid:
Full Justified Margins
This format makes straight margins on both sides of the page. It can be hard to read because the spaces between words are not all the same, creating holes in the text. Newspapers often use full justification so the sides of their columns are straight.
Centred Text:
This format is fine for titles and headings. You should not centre
paragraphs of text, because it is harder for readers
to find
the beginning of each line.
