Oracle Windows - changing the font in SQL*Plus

Oracle Database Tips by Donald Burleson

Robert Leistner has a great tip on changing the display font for SQL*plus in Windows.  By changing registry settings you can change the display font in SQL*Plus:

"How to change the font which is in use within SQL*Plus into "Courier New", Characterset "EASTEUROPE"? The trick is, you must change the registry:

For SQL*Plus (DOS)

  1. go into HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Console\TrueTypeFont
    and add a new entry. There exist already one entry "0" - "Lucida Console".

  2. You must create a new entry, for instance "00" - "Courier New". Use for the value name only zeroes, e.G. "00", "000" ...

  3. After that, open the "Command Prompt" Properties. Now you can select "Courier New" additionally. No shutdown (in XP) is necessary, you must not close and open the command promp-window!  . . .

For SQL*Plus (Windows)

go into HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE - current home and change or create new registry-entries for:

  • "SQLPLUS_FONT" = "Courier New"


  • additionally you can change the size using:
    "SQLPLUS_FONT_SIZE" = "16" "
