CSS - size

The size CSS at-rule descriptor, used with the @page at-rule, defines the size and orientation of the box which is used to represent a page. Most of the time, this size corresponds to the target size of the printed page if applicable.

Example

@page {
  size: 4in 6in landscape;
}

Syntax  

/* Keyword values for scalable size */
size: auto;
size: portrait;
size: landscape;

/* <length> values */
/* 1 value: height = width */
size: 6in;

/* 2 values: width then height */
size: 4in 6in; 

/* Keyword values for absolute size */
size: A4;
size: B5;
size: JIS-B4;
size: letter;

/* Mixing size and orientation */
size: A4 portrait;

Description  

The size CSS at-rule descriptor, used with the @page at-rule, defines the size and orientation of the box which is used to represent a page. Most of the time, this size corresponds to the target size of the printed page if applicable.

Size might either be defined with a "scalable" keyword (in this case the page will fill the available dimensions) or with absolute dimensions.
