I was asked if this:
Is better than this:
Most slide decks that pass through our department have the bullets single spaced, as this is the default in the corporate template, which makes it the defacto corporate style, and most of our SME developers don’t care one way or the other. But occasionally we see that a developer has double- or triple-spaced bullets. Usually, a developer who does this cares a lot, arguing either that it increases readability or that it avoids crowded text atop an awkward chasm of white.
We try and steer developers toward the corporate style absent a good reason to deviate, so I did a quick search to see if there was anything in the typography literature to help out. I was surprised that I couldn’t find much about line spacing as it relates to bullets, line spacing, and readability. One article suggests that short bullets don’t need much text between them, but longer bulleted blocks of text probably do, which, oddly, is kind of the opposite of what I see developers doing–I think because the biggest driver of the double spacing is discontent with the large amount of white space that can result from single spacing a small number of short bullets.
Ultimately this is probably minutia, which is why no one has written anything about it or researched it, but if anyone has any pointers to the typography literature on this stuff, I’d appreciate it.
