How to adjust terminal/console frame width

Question

Hi folks,
Archlinux 86-64 2007-08-2
I have 20" wide LCD screen.  How to adjust the window frame size of terminal/console allowing typing to its end rather than after typing a few words the cursor jumps to the beginning overtyping the same line?  TIA

Did you modify your PS1?
Hi,
Yes, PS1 is what I need.  Previously I searched on wrong terms.
After commenting out "PS1='[\u@\h \W]\$ ' " I added follows;
BLUE=`tput setf 1`
GREEN=`tput setf 2`
CYAN=`tput setf 3`
RED=`tput setf 4`
MAGENTA=`tput setf 5`
YELLOW=`tput setf 6`
WHITE=`tput setf 7`
PS1='\[$GREEN\]\u@\h \[$BLUE\]\w/\[$GREEN\] \$\[$WHITE\] '
That is what I need to display on terminal/console. 
However I still can't manage to have "black" fore-ground (black characters on typing).  I played around on following variation without result.
BLUE=`tput setf 1`
GREEN=`tput setf 2`
CYAN=`tput setf 3`
RED=`tput setf 4`
MAGENTA=`tput setf 5`
YELLOW=`tput setf 6`
WHITE=`tput setf 7`
BLACK=`tput setf 8`
PS1='\[$GREEN\]\u@\h \[$BLUE\]\w/\[$GREEN\] \$\[$BLACK\] '
BLACK=`tput setf 1`
GREEN=`tput setf 2`
CYAN=`tput setf 3`
RED=`tput setf 4`
MAGENTA=`tput setf 5`
YELLOW=`tput setf 6`
WHITE=`tput setf 7`
PS1='\[$GREEN\]\u@\h \[$BLUE\]\w/\[$GREEN\] \$\[$BLACK\] '
Advice would be appreciated.  TIA
Besides how to change the colour on "nano"?  The characters are difficult to read on typing.  I need black characters on white background
