It's more like resizing the character window or the inventory window or dialogue windows, IT'S NOT IN THE DAMN HUD LAYOUT! Get that "it has to be in the hud layout to change the size" nonsense out of your head. When the element in question pops up, make sure it is selected, then press R3 until it is the size you want, hell, if you want, press L1+R3 and then push and hold L2 with the courser over the big ass X in the upper right corner, you can now move the window where ever your little heart desires.
THE MORE YOU KNOW!
