ReSize widget network

Hi there,

I have 4 widgets on my website www.yvymag.com and we just changed our
layout.. I want to know if its possible to have the widgets with 135
px width to put on besides the other... and if is not possible how can
i edit to make them larger but without delet and install a new one...
Just update the ones that are already online...

I try to find but I didnt find it..

Thank you Marcello
