Many paged/printing tests from Microsoft have/use and reuse the expression

"standard letter sized sheet of paper"

but such expression does not equate to explicit dimensions and such
expression may vary depending on the continent. If "standard letter
sized sheet of paper" means US Letter (216mm width by 279mm height which
is 8˝ inches width by 11 inches height), then I think some tests where
measurement or overflow situation are being tested should indicate so. I
think this should even be clearly mentioned in the common or uncommon
assumptions paragraphs: what is exactly a standard letter sized sheet of

I believe - and I could be wrong here - that standard letter sized sheet
of paper is

US Letter: 216mm width by 279mm height which is 8˝ inches width by 11
inches height in North America

A4: 210mm by 297mm height in European Union countries.

Today the [A4] standard has been adopted by all countries in the world
except the United States and Canada.

Another issue is page margins for printing: reliable and trustworthy
testing would require also to know such values or to propose such
values. I printed position-fixed-005 with several browsers - with
default margins - and the difference of margins is rather very big,
unexplicably big. I have checked the page setup settings.

With Chrome 21.0.1180.89 with default settings, once printed, the right
margin of position-fixed-005 is at least 15% of the whole paper sheet
and I have default margins set.
