How to set/change LXTerminal font for standard user?

debian8 is a standard user on my OS (Debian8+LXDE). I follow below steps to change the font on LXterminal. 1. Launch LXterminal after logging in as debian8. 2. Click Edit > Preferences. 3. The default font size is 10 px, which is small. 4. I change the font size to 14 px. 5. Click OK to apply the changes. Unfortunately, when the computer is restarted, the font size for user debian8 reverts to 10px regardless of the font size chosen before restart. Why is that so? Is there a script which can be saved on /home/debian8/.bashrc to set font size for user debian8?
