I click in terminal: terminal->132x43 to change terminal size but after each reboot terminal size is set to default setting and I have to change it again. How to set it permanently?

You should go to Edit->Profile Preferences, General page and check Use custom default terminal size, and then set your preferred horizontal and vertical dimensions.

Ubuntu 16.04 and later

In Ubuntu 16.04 open the terminal, select Edit->Profile Preferences -> General tab and change the values for columns and rows after where it says Initial terminal size:.

  ^16.04

In Ubuntu 17.10 and later open the terminal, select Edit->Preferences -> Default profile -> Text tab and change the values for columns and rows after where it says Initial terminal size:.

  ^{17.10 and later}

Press Ctrl + Alt + t to open a terminal. Make sure the terminal is maximized (if it isn't already) by clicking on the right-most icon at the top of the window (the square in the circle). At the top of the window you should go to Edit -> Profile Preferences, General page and check Use custom default terminal size, and then set your preferred horizontal and vertical dimensions. If you would like unlimited scrolling, go to the Scrolling tab and put a check in the Unlimited box. Hope this helps!

In older versions you can find this setting in the /usr/share/vte/termcap/xterm file.

Here's a little script to really permanently set a window size, regardless of gnome-terminal profile that you are currently using. This works on all windows belonging to gnome-terminal

To make it work, you need two things: 1) make sure you have wmctrl installed and 2) run this script as one of the Startup Applications.

Notice that line with wmctrl -i -r $WMCTRL_ID -e 0,0,0,650,650 sets size and position according to gravity,x-position,y-position,width,height format

APP_CLASS="gnome-terminal.Gnome-terminal"



while [ 1 ]; do

  WIN_ID=$(printf %x $(xdotool getactivewindow))

  WM_CLASS=$(wmctrl -lx | awk -v search=$WIN_ID '{ if($1~search) print $3 }')

  WMCTRL_ID=$( wmctrl -lx | awk -v search2=$WIN_ID '$0~search2 {print $1}' )

    if [ $WM_CLASS = $APP_CLASS ]; then

           wmctrl -i -r $WMCTRL_ID -e 0,0,0,650,650

sleep 0.25

Linux Mint 19.1 (Xfce)

1. Open Linux Mint Menu button


2. Select Settings
   


3. Select Xfce Terminal
   


4. Navigate the new Terminal preferences window to the Appearance Tab.


5. Set the Default Geometry, to your preference.


6. Close and Enjoy.

However, the user config file is located in:
~/.config/xfce4/terminal/terminalrc

and the config item you need (for Xfce) is:
MiscDefaultGeometry.

But you can edit faster from the command line with:

sed -E 's/MiscDefaultGeometry=.+$/MiscDefaultGeometry=140x40/' -i ~/.config/xfce4/terminal/terminalrc

Where we have set the size to 140x40 as an example.
