TextRenderer.MeasureText Method (String, Font)

.NET Framework 4.5

Provides the size, in pixels, of the specified text when drawn with the specified font.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)

public static Size MeasureText(
	string text,
	Font font
)

Parameters

text: Type: System.String
The text to measure.

font: Type: System.Drawing.Font
The Font to apply to the measured text.

Return Value

Type: System.Drawing.Size
The Size, in pixels, of text drawn on a single line with the specified font. You can manipulate how the text is drawn by using one of the DrawText overloads that takes a TextFormatFlags parameter. For example, the default behavior of the TextRenderer is to add padding to the bounding rectangle of the drawn text to accommodate overhanging glyphs. If you need to draw a line of text without these extra spaces you should use the versions of DrawText and MeasureText that take a Size and TextFormatFlags parameter. For an example, see MeasureText(IDeviceContext, String, Font, Size, TextFormatFlags).

Remarks

The MeasureText method requires that the text is drawn on a single line.

Examples

The following code example demonstrates how to use the MeasureText method. To run this example, paste the code into a Windows Form and call MeasureText1 from the form's Paint event handler, passing e as PaintEventArgs.

private void MeasureText1(PaintEventArgs e)
{
    String text1 = "Measure this text";
    Font arialBold = new Font("Arial", 12.0F);
    Size textSize = TextRenderer.MeasureText(text1, arialBold);
    TextRenderer.DrawText(e.Graphics, text1, arialBold, 
        new Rectangle(new Point(10, 10), textSize), Color.Red);  
}
