I'm not sure if this is addressing your situation, but the simplest way
to adjust all font sizes is to use the rcParams dictionary, either
directly or via the matplotlibrc file. If the default font sizes for
various items are specified using "medium", "large", etc, instead of
with numerical values in points, then everything can be scaled by
changing the single value, font.size, which is the point size
corresponding to "medium".
