Data type Range Default value
REG_DWORD Buffer size 0x00190050


Determines the size of the screen buffer (the screen that is retained in memory). If the size of the screen displayed on the monitor is smaller than the screen buffer, you can scroll to see the entire screen. You cannot display a console screen that is larger than the screen buffer.

The value of this entry is an 8-byte hexadecimal value. The first four bytes (high word) represent the number of characters that appear on each line of the screen. The last four bytes (low word) represent the number of lines of text on the screen.

For example, the default value, 0x00190050, indicates that the screen buffer is 25 (0x19) lines high and 80 (0x50) characters wide.

Change method

To change the screen buffer size, click the system menu icon in the title bar, and then select either Defaults to change the settings for all instances of that window, or Properties to change the current window only. Click the Layout tab, and then use the Screen Buffer Size group box to set the width and height.

Activation method

Changes made in the Properties dialog box are effective immediately. Changes made in the Defaults dialog box or in the registry are effective the next time you open a console window.

The values in the registry reflect the default window settings.
