I am not quite sure how this works, but how does one use the article
format AND the a4 format at the same time? i.e., How can I load
both?

How about something like:

\documentstyle [a4,12pt]{article}

Works for me in*on our Sun's, but hey, TeX is Tex right?

\documentstyle[a4]{article}
So easy!

Why do you need a German size in Australia?

Because in Australia A4 paper is the standard size for photocopiers, laser
printers etc... We are more like Europe than the US, i.e. our TV's are PAL,
not NTSC, we use metres, kilometres etc.., not miles and inches, ...

Strewth! Talk about a "Sydney or the Bush" attitude! A4 is *not* a German
size. It is an international metric paper size recommended by the
International Standards Organisation. (And used by most sensible countries as
their standard paper size :-) ^^^^^^^^

Seriously though, A4 paper is derived from A0 paper. There are several A paper
sizes, all derived from the basic A0 size, as follows:

A0 - 1189 mm x 841 mm
A1 - is half A0
A2 - is half A1, and so on down to A7 size.

The diagram below represents an A0 sheet. (It's not to scale, but you'll get
the idea.)

| | | A5 |
| | | |
| | A4 |------|
| | | |A7|
| | | A6|--|
| | | |A7|
------------------------------

The standard also allows for larger sizes, but here the number precedes the
letter: 2A is twice A0.

German size indeed. Hurrumph! :-) :-)

"Strewth", "Sydney or the Bush", and other Australian idiom explained on
request.

Cheers,

A0 - 1189 mm x 841 mm

And in case somebody doesn't know, this makes one square meter.

Then there are parallel series of B and C sizes used for envelopes.
An A4 paper fits into a B4 envelope, etc.

That is almost correct. For those who wonder what 1189x841 has to
do with metric sizes I have the following information:

A0 describes the dimensions of a rectangle with a size of
1 square meter and with two sides the square root of 2 times
as long as the other two sides.

This has the nice property that if you divide such a rectangle
in two rectangles of the same size and if you make that division
by dividing the longest side into two, that length of the resulting
sides of the smaller rectangles have the same length with respect
to each other. (one against the square root of two) etc. etc. etc.

B0 - 1414 mm x 1000 mm

Does anybody know the details about the C size?

Summary:
A0 - 1189 mm x 841 mm
B0 - 1414 mm x 1000 mm

Requested:
C0 - 1297 mm x 917 mm

Question:
A0 is one square meter.
In B0 1.414 is SQRT(2).
But where is C0 derived from?

$1.297 \times 0.917 \approx 1.893 \approx 2^{.25}$! Possible
explanation: The Cn sizes were chosen so the new dimensions
would be interleaved within the Bn sizes, maintaining uniform
spacing on a logarithmic scale. My understanding of these systems
is that the aspect ratio of a piece of paper is maintained as
the paper is sequentially folded in half. Eventually a sufficient
number of folds will result in a piece of paper which will fit
an envelope with the same aspect ratio. Perhaps the Cn series
works out better in practice than the Bn series.

B0 is 1414 mm x 1000 mm (the same square root of 2 to 1 ratio).

C0 is 917 mm x 1297 mm which falls between B0 and A0. C sizes are used
solely
for envelopes.
