Hi Paul, thanks for your response. Yeah, sorry, no justification was being used.

Nice idea to measure by 100. It's interesting how different that comes out from using 12 spaces (which gives me an average of 0.83 inches per space).

For my particular project, I was working on a hanging indent of "two spaces" to comply with some style guidelines. I think the reviewers actually want me to insert manual line breaks in runover lines of text in the table of contents and manually hit the space bar twice, but I'm trying to develop a template for myself for future work so that's why I was looking for a measurement.

Your measurement seems more accurate, but I have a feeling that they might be eyeballing the hanging indent based on the letters on the line above it (which is not going to give a consistent comparison of course, but I get the impression that that's what they're doing). I'm curious to see how the next document review comes back but this was really helpful discussion. Thanks again for your response.
