Answer 1

With the help of Javascript you can calculate the width and height of browser and pass this info to server using AJAX .

Else not possible by ruby code .

EDITED :

If you are working on rails app than you can do it like :

To get the browser dimension use the link :

And if you using jQuery then use below function to get the height and width of window .

$(window).width();
$(window).height();

And use Ajax feature to pass this dimension to your action .
