Column.Width Property

Gets or sets the column width.

Namespace: DevExpress.Spreadsheet

Assembly: DevExpress.Spreadsheet.v24.1.Core.dll

NuGet Package: DevExpress.Spreadsheet.Core


double Width { get; set; }

Property Value

Type Description

The column width in measurement units defined by the Workbook.Unit property.


Type Description

Occurs if the column width exceeds 255 characters.


This example demonstrates how to control the column width in a worksheet.

Set the Width for Individual Columns

To specify the column width in characters of the default font specified by the built-in Normal style, use the Column.WidthInCharacters or CellRange.ColumnWidthInCharacters property.

To specify the column width in pixels, use the column’s Column.WidthInPixels property.

To set the column width in other measurement units, set the Workbook.Unit property to the required DocumentUnit enumeration member and specify the Column.Width or CellRange.ColumnWidth property.


If the column width is set to 0, the column is hidden. You can also use the Column.Visible property to hide a column or display the hidden column again.

AutoFit Column Width

To automatically change the column width to fit the contents, use the columns’s Column.AutoFit method. To quickly autofit several columns in a worksheet, call the ColumnCollection.AutoFit method.

Match the Width of Two Columns

To match one column width to another, you can use the Column.Width property or the CellRange.CopyFrom method of the column object.

Set the Default Column Width

To set the default width for worksheet columns, use the Worksheet.DefaultColumnWidthInCharacters, Worksheet.DefaultColumnWidthInPixels or Worksheet.DefaultColumnWidth property. These properties do not affect columns with an explicitly specified width.

Set the Width for All Columns in a Worksheet

To change the width of all columns in a worksheet, use the CellRange.ColumnWidthInCharacters or CellRange.ColumnWidth property of the Row object corresponding to any row in a worksheet. This sets the width of all columns to the same value, overriding all previously applied column width settings.

View Example

// Set the "B" column width to 30 characters of the default font that is specified by the Normal style.
worksheet.Columns["B"].WidthInCharacters = 30;

// Set the "C" column width to 15 millimeters.
workbook.Unit = DevExpress.Office.DocumentUnit.Millimeter;
worksheet.Columns["C"].Width = 15;

// Set the width of the column that contains the "E15" cell to 100 points.
workbook.Unit = DevExpress.Office.DocumentUnit.Point;
worksheet.Cells["E15"].ColumnWidth = 100;

// Set the width of all columns that contain the "F4:H7" cell range (the "F", "G" and "H" columns) to 70 points.
worksheet.Range["F4:H7"].ColumnWidth = 70;

// Set the "J" column width to the "B" column width value.
worksheet.Columns["J"].Width = worksheet.Columns["B"].Width;

// Copy the "C" column width value and assign it to the "K" column width.
worksheet.Columns["K"].CopyFrom(worksheet.Columns["C"], PasteSpecial.ColumnWidths);

// Set the default column width to 40 pixels.
worksheet.DefaultColumnWidthInPixels = 40;
