Ideally, it would be to choose 3 font types which have approximatively the
same x-height ratio aspect of font (this is best for several reasons) and
with each font being present on each os (Windows, Mac, Linux).

Estimating the x-height of a font

Aspect values for web fonts

x-height, etc.

Most common serif fonts found/installed on Windows, Mac and Linux

Arial and Verdana are sans-serif fonts whereas Times New Roman is a serif

Times New Roman has a ratio of 0.45 while Verdana has a ratio of 0.55;
they are not ideal together.

FreeSerif (83% of the time found in Linux distribution) has a x-height
ratio aspect of 0.45. So, FreeSerif along with Times New Roman would meet
my requirements.
And then, Liberation Serif (86% of the time found in Linux distribution)
has a x-height ratio aspect of 0.46: that would be my 2nd choice for

div {font-family: FreeSerif, "Liberation Serif", "Times New Roman", serif;}
You should always start with the most difficult to find font type and then
end with the most available one


The ideal webpage on line box, inline box, line-height, vertical-align,
leading, etc... would be one that uses good diagrams, meaningful examples
and would be exempt of errors.

I have something very clear in mind ... but I very much lack available
time for this.
