Hello gin98,
A 3½ inch floppy disk has about 1.44 MB of space.  When this is
converted into KB, we have:
1.44 MB * 1024 KB/MB = 1474.56 KB
A typewritten page takes up about 2 KB.  So, a floppy disk will hold
approximately:
1474.56 KB * 1 page/2 KB = 737 pages.

So, to answer your question, a 3½ inch floppy disk will be able to
hold approximately 700 pages of typewritten text.

I hope that is the answer you're looking for.  If you need
clarification, please request for it before rating this answer.

Actually waaayyy more information that I needed - just the bottom line
answer and not the formula would have been sufficient - but thank you.

Dear Gin98,

Secret901's answer may answer what you asked, but not necessarily what
you need to know.

I'm not sure where James S. Huggins gets his figure of 2 kilobytes per
typewritten page.  That sounds rather more like a double-spaced page
to me, in other words you may get twice as many characters per normal
page and half as many pages per diskette as Secret901 suggests.

But there are other points to consider.  If you are going to print the
text on a (computer) printer, rather than type it on a real steam
typewriter, you may well use a different pitch and line spacing from a
genuine typewriter's.  This way, you can easily squeeze a lot more
into a printed page; this reduces the number of pages you can store
per diskette.

And you may be - in fact, you very probably are - preparing the text
using a word processor.  If you allow the word processor to store your
work on the diskette in its own document format rather than as a plain
text file, as you will probably want to, this can easily be very much
larger than the text size itself suggests.  Again, you will get fewer
pagers per diskette than you might have thought.

Another minor point is that a simple calculation of diskette capacity
assumes that all the text is in a single file.  Every file has some
wasted space, so if, say, you store ten chapters as separate files,
you will have ten lots of wasted space.  In extreme cases, this can be
significant.

Oh, and we are assuming that you have high-density diskettes, with
1.44-megabyte capacity: there still exist similar-looking
double-density 3.5-inch diskettes with half this capacity.
