When I write $x_i^j$, the j is very high up, and it looks ugly. (This problem is especially apparent in the New Century Schoolbook font.)

$x_i^j$

I know that TeX is capable of automatically lowering it, since for example, $x_i^1$ looks fine. Is there a clean way to fix this?

\documentclass{article}
\usepackage{fouriernc} % use the New Century Schoolbook font
\begin{document}
Contrast $x_i^j$ to $x_i^1$.  Why is the $j$ so high up?
\end{document}

What do you mean with "very high"? What I observe with the compiled code given is the default output of TeX. But if you want to raise or lower the j then that is something else. –  azetina Apr 13 '12 at 19:18

If you use \smash{j} instead of j TeX will think it has zero height and (more importantly) zero depth and it will look more like the version with the 1. –  Roelof Spijker Apr 13 '12 at 19:24

Have a look at the tensind package. It sets the high and low indices properly aligned. –  Peter Breitfeld Apr 13 '12 at 19:30

Check below code:

\documentclass{article}
\usepackage{fouriernc} % use the New Century Schoolbook font
\begin{document}
Contrast $x_i^{\smash{j}}$ and $x_i^j$ to $x_i^i$.  Why is the $j$
so high up?
\end{document}
