# [NTG-context] matching font sizes with fallback fonts

```Dear list,

I’m trying to match the fallback font size with the lowercase size of
the main font, as shown in this sample:

\usemodule[simplefonts][size=90pt]
\setmainfontfallback[GFS Neohellenic]
[range={greekandcoptic,greekextended}, force=yes, rscale=auto]
\setmainfont[TeX Gyre Pagella]
\starttext
aα γg AΑ ΒB
\stoptext

But rscale=auto doesn’t seem to work (if this is the right option).

What am I doing wrong here?
