Like everyone else, I know at this time Revit does not provide much support for text notes. Without the usual software support I decided to follow up on one comment made by several people that the line height depends on the font. I used Arial 3/32" for comparison. Using the same text height I found that Arial Unicode MS provides 118% line spacing and Dubai provides 162% line spacing compared to standard Arial. Arial Unicode has the same width and, of course, looks the same. Dubai is slightly wider at 102% and looks almost the same. I started searching alphabetically in Word and stopped at about "E". The comparisons were done in Revit. Interestingly, when other software displays fonts, their actual size may vary. Dubai would be smaller than Arial at the same point size. However, with Revit it is physically the size defined for its family type, i.e., it really is 3/32" and not affected by its underlying characteristic height - a good thing.
If others find similar information for other fonts, please share. At the rate Autodesk addresses these kinds of issues, it may by a decade and thousands of dollars of subscription fees before this is remedied.
