Solving an xrandr issue with size of font

I have the next line in my ~/.xsession script

xrandr --size 1600x1200

I found this line is the reason why fonts in applications become bigger than usual

I found the solution of the problem at Xfce forum here: weird font-size issue (xrandr) (Page 1) / Desktop / Xfce Forums.

To solve the problem I just added the next line after the line from the first listing.

xrandr --dpi 96
