I thought two spaces was the standard. But then I was unsure so I started typing some nonsense in a word document to test it out and I only hit one space. But I'm confused because I thought for sure I did two. I don't think I notice a difference though when I look at it. Interesting.
I'm in a pretty dire situation at work right now. I just received a document that has two spaces after each period.
Two spaces is fine even though the standard now is one space. Two spaces are still used sometimes in certain technical documents because it can be more pleasing to the eye if there are a lot of bs $50 words. If you're trying to convert (rather than just being annoyed), you can "replace all" and just type "period space space" replace with "period space". Should make it look better. Only thing it won't change are sentences that end in question marks or exclamation points.
When did it become preferred to only use one space after periods? I don't like it. Is this a sign that I'm old? I'm concerned that it is because bogart just indicated that he graduated in '07 as though that was a long time ago, and I graduated ten years before that (incidentally, the girl at the bank told me the other day that I don't look a day over 25; that doesn't have anything to do with this; I just wanted to mention it). Luckily, we use two spaces at the end of our sentences here, so I have not been forced to get used to something new and offensive to my eyes.
I graduated in '99 and we used single spaces back then. maybe it's a regional thing?
