Quest window "L" text size only
 

Ok, I know how to increase the scale, but this would increase size of everything with the window included, but I want to keep the window the same size while only increasing the size of the text that is to the left hand size. I found the option to increase the size of the object text that is to the right, however I want to increase the text to the left size, thanks.

Sorry dont understand what u want to do. Make screen and mark place u want to increase font size.
