// get hidden element actual innerHeight
$( '.hidden' ).actual( 'innerHeight' );

// get hidden element actual outerHeight
$( '.hidden' ).actual( 'outerHeight' );

// get hidden element actual outerHeight and set the `includeMargin` argument
$( '.hidden' ).actual( 'outerHeight', { includeMargin : true });

// please see demo/css3pie in action
$( '.hidden' ).actual( 'width', { clone : true });

// if you are not use block element. By default { display: 'block' }.
// for example a inline element
$( '.hidden' ).actual( 'width', { display: 'inline-block' });
