Grammar Hammer: Two Spaces or Not Two Spaces?

I’m of the age that one of the classes I took in high school was typing. Putting two spaces after the period at the end of a sentence was drilled into our heads as a best practice with no rhyme or reason for why this was necessary.

Recently, a heated discussion over whether this practice is correct or incorrect surfaced on my social media feed, a subject I felt was worth discussing in this edition of Grammar Hammer.

There is some history to the “two space” practice. I’d always thought it had to do with the art of typesetting and those who manually set each letter and block. The “modern” convention of one space following the end of a sentence is traced back as far as the early 1920s.

In today’s digital world, two spaces is unnecessary, and as such I’ve discontinued the [space space] habit pounded into my brain from my younger years.

What are your convictions on this subject? Are you a die-hard two spacer? Or have you adapted to the freedom that digital media provides and go with the single space after your sentence’s punctuation?
