I have always felt that the 10 pt font looks nicer than 12 pt, either in PDF or printed. The 12 pt looks taller (in other words the 10pt looks fatter).
My questions are:
- Is the 12 pt font a scaled version of the 10 pt one?
- If not, then how can we create a new 12 pt font by scaling the 10 pt one (in both LaTeX and XeLaTex)? It seems that by doing so we'll obtain a thicker version of the 12pt font.
