    How to Change Screen Buffer Size of Console Window in Windows


    A console (or "terminal) is an application that provides I/O to character-mode applications.

    For example: command prompt, PowerShell, or Linux

    The screen buffer size of a console window is expressed in terms of a coordinate grid based on character cells.
    • The width is the number of character cells in each row. The larger the width size, the more text will show in the same row before wrapping.
    • The height is the number of rows. The larger the height size, the further you can scroll before output data (text) is overwritten.

    This tutorial will show you how to change the screen buffer size of a console window (ex: command prompt, PowerShell, Linux) for your account in Windows 7, Windows 8, and Windows 10.

    The screen buffer size you set for a console window will only be applied to the specific console window shortcut that opened it.

    For example, command prompt opened via Win+X menu VS Run (Win+R) dialog. Each location would have its own settings.

    OPTION ONE

    To Change Screen Buffer Size of Console Window in Properties


    1 Open a command prompt, elevated command prompt, PowerShell, elevated PowerShell, or Linux console window you want using the shortcut or location you want to apply a custom screen buffer size to.

    You could also just directly right click on the console window shortcut or file, click/tap on Properties, and go to step 3 below.


    2 Right click or press and hold on the title bar of the console window, and click/tap on Properties. (see screenshot below)

    3 Click/tap on the Layout tab, make any width and height adjustments you want for Screen Buffer Size, and click/tap on OK to apply. (see screenshot below)

    The width size you set under Screen Buffer Size will also be applied to the width size under Window Size.

    OPTION TWO

    To Change Screen Buffer Size of Console Window using "Mode" Command


    The screen buffer size you set using this option will only be temporary, and only used while the console window is open unless you use Option One above to set it as default.


    1 While you have a command prompt, elevated command prompt, PowerShell, or elevated PowerShell console window open, do step 2 (current size) or step 3 (change size) below for what you would like to do.


    2 To See Current Screen Buffer Size of Console Window

    A) Copy and paste the mode con command into the console window, and press Enter. (see screenshot below)

    Lines = height size

    Columns = width size

    3 To Change Current Screen Buffer Size of Console Window

    A) Type the command below into the console window, and press Enter. (see screenshots below)

    mode con:cols=<Width Size> lines=<Height Size>

    Substitute <Width Size> in the command above with the value (ex: "90") you want for the screen buffer width size. The width size you set for Screen Buffer Size will also be applied to the width size for Window Size.

    Substitute <Height Size> in the command above with the value (ex: "20") you want for the screen buffer height size.

    For example: mode con:cols=90 lines=20

    Shawn, just a note, for Option 2.

    The command:
    mode con:cols=<Width Size> lines=<Height Size>
    or
    mode <Width Size>, <Height Size>

    has a slight problem, which you have already noted “the width size you set under Screen Buffer Size will also be applied to the width size under Window Size”.

    So if somebody just wants to change the Screen Buffer Size (Height size) without altering the size of the window the only solution I found was to run from the command prompt, the following PS commands, as PowerShell can alter just the buffer size, without changing the window size:

    Code:
    %SystemRoot%\system32\WindowsPowerShell\v1.0\PowerShell.exe -ExecutionPolicy ByPass -NonInteractive -Command "& {$NewBufferSize=$Host.UI.RawUI.BufferSize;$NewBufferSize.Height=3000;$Host.UI.RawUI.BufferSize=$NewBufferSize;}"
    OR
    Run the bat file Change_Buffer_Size.bat

    This will open a PS session, change the Screen Buffer Size of the current Command Prompt window, and will close, without the user noticing anything.

    Thanks very much! it is exactly what I was looking for!!
    Once the size is customized, does somebody know the registry key corresponding to this settings ?? I would like to backit up for future easy restore.
    PS: I need to the Telnet windows. Why? I use to reboot my router through Telnet, and like a small minimalist windows, so I resized the windows to the angle of my screen when launched, some now I would like to my a backup of my settings....
