I'm an author. In my document, when I enter the title and my name it should be centered but it's not. I can see that it's slightly off. Why?
I'm talking about at the top of the document


Title of Book
by
My Name
It's off by several letters of being centered.
I use the default page setup, hit "center" for the alignment, then type in the info, but it's off.
Any ideas? Thanks!

You should use the Title and Subtitle styles for these and modify them to be centered rather than direct formatting.

No one can tell you why centering seems to be off without looking at a sample document. Please attach one without any proprietary information.

Thanks, Charles, that worked.

Then I tried to duplicate the uncentered one, but now it centers. So maybe doing that "fixed" it, lol.
