Property Value

Type: System.Int32

The current width, in columns, of the buffer area.

The value in a set operation is less than or equal to zero.


The value in a set operation is greater than or equal to Int16.MaxValue.


The value in a set operation is less than WindowLeft + WindowWidth.


The user does not have permission to perform this action.


An I/O error occurred.

If a set operation decreases the value of the BufferWidth property, the rightmost columns are removed. For example, if the number of columns is reduced from 80 to 60, columns 60 through 79 of each row are removed.

This example demonstrates the BufferHeight and BufferWidth properties. The example reports the dimensions of an operating system window set to a buffer size of 300 rows and 85 columns.

// This example demonstrates the Console.BufferHeight and 
//                               Console.BufferWidth properties.
using System;

    public static void Main() 
    Console.WriteLine("The current buffer height is {0} rows.",
    Console.WriteLine("The current buffer width is {0} columns.",
This example produces the following results:

The current buffer height is 300 rows.
The current buffer width is 85 columns.
