I just want to place a tilde over $\mathcal{W}$, and $\tilde\mathcal{W}$ is too small while $\widetilde{\mathcal{W}}$ is too big.
Is there a simple way to produce an in-between?

It's a bit hacky, but does
\usepackage{amsmath}
$\overset{\sim}{\mathcal{W}}$
(which gives
) do what you're after?
Edit:
An alternative with adjustable height is
\newcommand\Wtilde{\stackrel{\sim}{\smash{\mathcal{W}}\rule{0pt}{1.1ex}}}
where you can change 1.1ex to whatever you like.
Note, however, that in this implementation the tilde height is entirely independent of the size of the original W, so you may need to define several versions if you want to do this to lots of different letters.

That's much better. Can one lower the tilde with
\raiseboxor the like? Commented Aug 4, 2011 at 10:29 -
1Following @HendrikVogt at tex.stackexchange.com/q/12579/6984 :
\newcommand\simcal[1]{\stackrel{\sim}{\smash{\mathcal{#1}}\rule{0pt}{1.1ex}}}lets you write$\simcal{W}$or whatever, and you can adjust the1.1exto suit your spacing preferences.– AntCommented Aug 4, 2011 at 11:08 -
PS - a meta-comment: anyone know how I can get the @ syntax to work with Hendrik's username above? Ta.– AntCommented Aug 4, 2011 at 11:09

On second thoughts,
\newcommand\Wtilde{\stackrel{\sim}{\smash{\mathcal{W}}\rule{0pt}{1.1ex}}}is better. In this implementation the spacing is entirely independent of the size of the original letter, so making the letter an argument is not a brilliant idea.– AntCommented Aug 4, 2011 at 11:15 -
This is much better (the comments version), could you add it to the answer? It is also much simpler than the (otherwise excellent) suggestion of Leo Liu. Commented Aug 17, 2011 at 14:42
Follow Ant's solution:
\documentclass{article}
\usepackage{accents}
\begin{document}
$\tilde W \widetilde W$
$\accentset{\sim}{W} \accentset{\textstyle\sim}{W}$
\end{document}
That's not very good. For more complicated solution, see How can I manually choose the size of a wide accent? (math mode)

1Could you elaborate on what's "not very good" about this solution? It actually looks quite nice to me.– Eike P.Commented May 5, 2020 at 15:16
