Open terminal on start in a specific place and size [duplicate]

The command is:

gnome-terminal --geometry=widthxheight+Xposition+Yposition

Add it under System -> Preferences ->Startup applications.

--geometry GEOMETRY

Specifies the startup geometry for this terminal. The geometry specifies the desired width and height in terminal characters. For example: --geometry=80x40 will create an eighty-column by forty-line terminal. You can also specify the location of the terminal Window on the screen; for example, --geometry=80x40+100+200 will create a Window whose top left corner is 100 pixels to the right and 200 pixels down from the top left corner of the screen, while --geometry=80x40+100-200 will give a Window whose bottom left corner is 100 pixels to the right and 200 pixels up from the bottom left corner of the screen.

Source

Example: gnome-terminal --geometry=80x40+100+200

To make it so it always keep that setting:

sudo gedit /usr/share/vte/termcap/xterm 

Locate something simliar to:

:co#80:it#8:li#24:\

co is column number and li is row number.

Not sure how to change the location in that file though, sorry.
