When typing your manuscript, do you put one space between sentences or two?
My own habit is to put two spaces between sentences because it's what I was taught. I'm even doing it as I type this blog, even though I know the second space will be ignored by the HTML code.
Looking for an answer in the various books I have doesn't help as none of them cover the subject, not even the ones on punctuation (curse you Lynne Truss).
A search of the internet throws up various opinions, the most comprehensive of which can be found on Wikipedia in an article on sentence spacing. The upshot of this article is that single spacing is the current convention, but that double spacing is still used widely, even being taught in schools.
An interesting point to note is that in typesetting and printing a single space has ALWAYS been in use and that double spacing was introduced for typewriters.
Other sites suggest, nay insist, that one space is correct such as 'Grammar Girl'. The Chicago Manual of Style also states that one space should be used.
If you've already tapped the spacebar twice in your 250,000 word novel, do not worry for help is at hand with a simple tip using the find/replace function in your word processing software.
Which is correct? I'm leaning towards single, but habit forces me to use double. What is your opinion?
