aspectRatio

Sets the width-to-height aspect ratio of the calendar.

A calendar is a block-level element that fills its entire available width. The calendar’s height, however, is determined by this ratio of width-to-height. (Hint: larger numbers make smaller heights).

The following example will initialize a calendar who's width is twice its height:

$('#calendar').fullCalendar({
  aspectRatio: 2
});

More precisely, this is the aspect ratio of the calendar's "content" area (the area with a className of "fc-view-container").

Setter

You can dynamically set a calendar's aspectRatio after initialization:

$('#calendar').fullCalendar('option', 'aspectRatio', 1.8);
