Well, of course you've just opened Pandora's box with that! <g>

From Microsoft's perspective, there would be six lines to the inch. This was irrespective of type size, acknowledging the familiar limitations of the office computer's predecessor, the typewriter. Many machine models could advance the page by single (line) space, double (line) space, or triple (line) space. Some machines could do one-and-a-half (line) spaces. It was all in the gearing in the carriage return.

The average office worker would be confused by typographic terminology. Their audience was migrating from typewriters to computers, so using familiar references, rather than leading, made sense for a word processing program.

But typography, of course, could always do variable spacing. And "one-and-a-half" line spacing would mean leading at 1.5x the font size. OK, that is if the original lines of type were sert solid. But if the lines had already been leaded a bit, then, what do you base the 1.5 line spacing on?

And points of line space on a typewriter, as well as on the computer, do not exactly match traditional typographic point size.

So, yes, I guess we should first agree on the meaning of a line! Or one could make a valid argument for any of several different interpretations of 1.5 line spacing! <g>
