Should headings be centered or left-aligned?
Text and headings should be flush left
Accordingly, text and headings should not be centered, flush right, or justified. As a left-to-right language, scanning English centered and flush right text is more difficult because location of the beginning of the lines changes.
Should Titles Be Centred?
The title of a complete work is usually centred near the top of the first page; if possible, it should be printed either in large letters or in boldface, or even in both. It should not be italicized or placed in quotation marks, and it should not have a full stop at the end.
