It strikes me that this approach produces what is called "default leading" (what you get with "single line spacing" in word processors, where "single" is taken literally) Generally, it is suggested by typographers to use a line spacing of 120% (at least) [1], although it certainly depends on the font design. Also, most document processors seem to use the factor 1.2 or 1.15 as default line spacing for the paragraph styles. I'd suggest to try how it looks if you use a factor of 1.15 or 1.2 either on the whole line spacing (ascent + descent + leading [2]) or only on the line height (ascent + descent) plus the leading on top of that. I know you are not a fan of prefs, but we could also consider here to add an option to modify the line spacing (defaulted to 1.2 for instance) in Prefs > Look & Feel > Screen Fonts, as the ideal value will both depend on the selected font and the users' reading habits. [1] E.g., https://practicaltypography.com/line-spacing.html [2] I suppose you have seen that there is also QFontMetrics::LineSpacing(), which equals height() plus leading(), whereas height() is ascent() + descent() + 1 (the 1 is for the base line). > Would someone have a good documentation on the subject (The TeXbook > uses > hardcoded values AFAICS) or a place where I can ask? There are many typophile fora out there, but if you ask there, be prepared to provoke a flame war. Jürgen > > JMarc >
