[Inkscape-user] Menu font size

I was wondering how I can could the menu fonts in Inkspace; it displays display significantly larger than other GTK applications. I found that by modifying the gtkrc files in \Inkscape\etc\gtk-2.0, I could get the size I wanted by replacing this line:

# gtk-font-name="tahoma 12"

with this one:

gtk-font-name="verdana 6.5"
