Using TeX Gyre Pagella Math with xelatex, some objects like \frac12 just seem way too large compared to the rest of the equations. Have a look: Ugly fractions in TeX Gyre Pagella Math

In the first line, the numerator looks like it's floating away. The second line using a \scriptstyle size looks better, but the baseline is off. Finally, the exponent in the very last line also looks off. Here it seems like it's sitting way too low.

Do I have a weird impression of these things, or does this simply not look nice? Can I somehow fix it?

MWE:

\documentclass[varwidth,convert]{standalone}

\usepackage{mathtools}

\usepackage[math-style=ISO,bold-style=upright]{unicode-math}
\setmainfont[Ligatures={TeX,Common}]{TeX Gyre Pagella}
\setmathfont{TeX Gyre Pagella Math}

\begin{document}

\begin{tabular}{@{}l@{}}
This is quite ugly:\\
\multicolumn{1}{c}{
\( \displaystyle   \frac12 \int x = 0.5 \int x \)
} \\
\multicolumn{1}{c}{
\( \displaystyle {\scriptstyle \frac12} \int x = 0.5 \int x \)
} \\
\multicolumn{1}{c}{
\( \displaystyle   e^{\frac12 x+1} = e^{0.5 x+1} \)
}

\end{document}

  • May be tweaking some \fontdimens by hand which are badly set in TeX Gyre Pagella Math? Off Topic: Is there a certain reason to use XeTeX rather than LuaTeX? – Manuel Aug 12 '14 at 15:30
  • I can't see any particular misplacement. The effect is probably amplified by the smallness of the integral sign in TeX Gyre Pagella. Rather than {\scriptstyle\frac{1}{2}} you should use \tfrac{1}{2} – egreg Aug 12 '14 at 15:37
  • You cannot use {\scriptstyle...} inside \displaystyle. Use \textstyle instead this. This is natural that the math axis of \scriptstyle is differently positioned than in \display/textstyle. The space between 1 and fraction rule in displaystyle can be corrected by \fontdimen8\textfont2 in normal math setting, but this is unicode-math which could be different (I don't know). – wipet Aug 12 '14 at 16:04
