dvips: 'papersize' special

 
 4.1 'papersize' special
 =======================
 
 The format of the 'papersize' special is
 
      \special{papersize=WIDTH,HEIGHT}
 
 WIDTH is the horizontal size of the page, and HEIGHT is the vertical
 size.  The dimensions supported are the same as for TeX; namely, in
 (inches), cm (centimeters), mm (millimeters), pt (points), sp (scaled
 points), bp (big points, the same as the default PostScript unit), pc
 (picas), dd (didot points), and cc (ciceros).
 
    For a US letter size landscape document, the 'papersize' would be:
      \special{papersize=11in,8.5in}
 
 An alternate specification of 'landscape':
      \special{landscape}
 
 This is supported for backward compatibility, but it is hoped that
 reventually the 'papersize' comment will dominate.
 
    Of course, such a '\special' only informs Dvips of the desired paper
 size; you must also adjust '\hsize' and '\vsize' in your TeX document
 typeset to those dimensions.
 
    When using the 'papersize' special, you generally should not also
 specify '-t' on the command line (⇒Option details).  The
 exception is when using a nonstandard paper size that isn't predefined;
 in this case, use '-t unknown'.
 
    The 'papersize' special must occur somewhere on the first page of the
 document.  Some packages, notably 'hyperref', insert this special.
 
    By default, if a DVI file contains multiple 'papersize' specials, the
 last one wins; this is also the behavior of the 'dvipdfmx' driver.  If
 the '-L0' command line option or 'L0' config file command is specified,
 the first special wins--this was the behavior of Dvips prior to the 2017
 release.
