This a very limited metric. You need to compare apples to apples. TTF
fonts shipped with WINOS2 are low quality. The high quality TTF fonts,
such as th so called MS web fonts, are comparable in size to the
PostScript fonts.

>The PostScript files, being larger, must contain more rendering info.

Without knowing the encoding method, there is no basis for this statement.
What if the TTF font encoding is LZW compressed internally?

Both are Bezier. See:

http://cgm.cs.mcgill.ca/~luc/ttvst1.html

TrueType's are simplier. Google for:

truetype bezier

if more links.

IIRC, I'm pretty sure PostScript came before TrueType.

http://www.visiongraphics-inc.com/tools/fonttech.html

seems to support this recollection.
