Okay, setting the resolution to 45 corrects the sizes:
pygame.freetype.init(resolution=45)
Python 2.7.3
pygame 1.9.2a0
pygame.freetype 2.4.10
radon.bdf 12
radon.bdf 13
radon-wide.bdf 12
radon-wide.bdf 13
c64.bdf 8
c64d.bdf 16
I don't know why this is the case. Explicit bitmap font support is not
built into the freetype module, so is untested. It is something I
intended, but have not got around too. Sorry.

Hi,
I don't know what exactly you are looking for. The BDF fonts are
bitmap fonts, so do not scale. Each font supports only a few specifc
sizes.
Freetype works in point size, which is not pixel size. Point size is
supposed to represent the size as viewed. By default it assumes there
are 72 points to an inch. So a point size of 10 should give around 7
characters per inch. However, the pitch value of 72 points per inch is
a builtin constant; it is not calculated from the actual screen
resolution. So actual font size will vary with the monitor used.
The freetype version of pygame.font.init() is just
pygame.freetype.init(). It takes a 'resolution' keyword argument that
sets the default pitch used in rendering. I suppose setting the pitch
to the screen resolution, in pixels per inch, makes the point size
equal pixel size. The pygame.freetype.Font type allows pitch to be set
individually for each Font instance. It is this pitch twiddling which
allows pygame.freetype.Font to mimic how pygame.font.Font handles the
default Pygame font, which is scaled differently from other fonts.

Lenard,
Sorry, updating to pygame-1.9.2a0-12de2da43ecb.win32-py3.3.msi didn't
help.
By passing a different (wrong) size, I was able to get freetype to
render some fonts but not others. I made a webpage with the only
documentation that I have found, some demo code that can render from
some BDF fonts, and a screenshot:
http://www.marshallworkshop.com/pygame/freetype-bug/
I suspect that there's a mistake in the documentation for
instantiating the pygame.freetype.Font class. If I follow the
documentation and pass it the font name, style and size, I get an
error. If I just pass only the font name and a certain (wrong) size,
it sometimes renders.

Hi Jason,
This sounds like issue #144, unable to render text.
<https://bitbucket.org/pygame/pygame/issue/144/unable-to-render-text>
The issue #144 fix is included in an updated 32bit Windows installer
added to the downloads page
<https://bitbucket.org/pygame/pygame/issue/144/unable-to-render-text>
earlier this week: pygame-1.9.2a0-12de2da43ecb.win32-py3.3.msi
<https://bitbucket.org/pygame/pygame/downloads/pygame-1.9.2a0-12de2da43ecb.win32-py3.3.msi>.
I have taken to adding a changeset identifier to the file name so
tracking installer versions will be easer.
