Last Updated : 11 Jul, 2025
Console.SetBufferSize(Int32, Int32) Method is used to set the height and width of the screen buffer area to the specified values.
Syntax: public static void SetBufferSize(int width, int height); Parameters: width: It sets the width of the buffer area measured in the form of columns. height: It sets the height of the buffer area measured in the form of rows. Return value: The new size of the buffer screen.
Exceptions:
  • ArgumentOutOfRangeException: If the height or width is less than or equal to zero Or height or width is greater than or equal to MaxValue. Also, if the width is less than WindowLeft + WindowWidth or height is less than WindowTop + WindowHeight then we will get the same exception.
  • IOException: If an I/O error occurred.
