Overview

Dimensions pulled from PDF::Writer, rubyforge.org/projects/ruby-pdf

All of these dimensions are in PDF Points, see Prawn::Measurements for conversion utilities.

Additionally, if the size you are after is not listed below, you can always specify your size by passing an array of width and height to Prawn::Document.new like:

Prawn::Document.new(:page_size => [1000, 20000])

The sizes below can be used by passing the appropriate string to :size:

Prawn::Document.new(:page_size => '2A0')
