jQuery working out wrong height, due to @font-face
The Google font api looks like it works as long as you load fonts from google, typekit or ascender. But if you are using something else (e.g. another font downloaded from fontsquirrel) you might want to try something like this to figure out the font being rendered.

The perfect solution was, as Adam pointed out, using $(window).load
instead of $(document).ready
$(window).load(function(){
$(".column").equalHeights();
});
