I factored this out of the plugin execution so that it doesn't need to be defined each time the plugin is called.

return function () {
self.css('font-size', Math.max(Math.min(
self.width() / (settings.compressor * 10),
parseFloat(settings.maxFontSize)),
parseFloat(settings.minFontSize)));
};
}

$.fn.fitText = function( kompressor, options ) {

$.fn.fitText = function(compressor, options) {
// Setup options
var compressor = kompressor || 1,
settings = $.extend({
'minFontSize' : Number.NEGATIVE_INFINITY,
'maxFontSize' : Number.POSITIVE_INFINITY
}, options);

return this.each(function(){

// Store the object
var $this = $(this);

// Resizer() resizes items based on the object width divided by the compressor * 10
var resizer = function () {
$this.css('font-size', Math.max(Math.min($this.width() / (compressor*10), parseFloat(settings.maxFontSize)), parseFloat(settings.minFontSize)));
};
var settings = $.extend({'compressor' : compressor || 1}, defaults, options);

// Call once to set.
resizer();
// Call on resize. Opera debounces their resize by default.
$(window).on('resize', resizer);
});
return this
.each(function(){
// Call on resize. Opera debounces their resize by default.
$(window)
.on('resize', resizer($(this), settings))
.trigger('resize');
});

};

})( jQuery );
}(jQuery));
