MeasureText Method (String, Font, Size, TextFormatFlags)

TextRenderer.MeasureText Method (String, Font, Size, TextFormatFlags)

Note: This method is new in the .NET Framework version 2.0.

Provides the size, in pixels, of the specified text when drawn with the specified font and formatting instructions, using the specified size to create the initial bounding rectangle for the text.

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

public static Size MeasureText (
	string text,
	Font font,
	Size proposedSize,
	TextFormatFlags flags
public static Size MeasureText (
	String text, 
	Font font, 
	Size proposedSize, 
	TextFormatFlags flags
public static function MeasureText (
	text : String, 
	font : Font, 
	proposedSize : Size, 
	flags : TextFormatFlags
) : Size



The text to measure.


The Font to apply to the measured text.


The Size of the initial bounding rectangle.


The formatting instructions to apply to the measured text.

Return Value

The Size, in pixels, of text drawn with the specified font and format.

MeasureText uses the proposedSize and flags parameters to indicate the relationship of height to width when determining the text size. When measuring text on a single line, if the proposedSize parameter represents a Size with a height dimension greater than Int32.MaxValue, the returned Size will be adjusted to reflect the actual height of the text.

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).

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

private static void DrawALineOfText(PaintEventArgs e)
    // Declare strings to render on the form.
    string[] stringsToPaint = { "Tail", "Spin", " Toys" };

    // Declare fonts for rendering the strings.
    Font[] fonts = { new Font("Arial", 14, FontStyle.Regular), 
        new Font("Arial", 14, FontStyle.Italic), 
        new Font("Arial", 14, FontStyle.Regular) };

    Point startPoint = new Point(10, 10);

    // Set TextFormatFlags to no padding so strings are drawn together.
    TextFormatFlags flags = TextFormatFlags.NoPadding;

    // Declare a proposed size with dimensions set to the maximum integer value.
    Size proposedSize = new Size(int.MaxValue, int.MaxValue);

    // Measure each string with its font and NoPadding value and 
    // draw it to the form.
    for (int i = 0; i < stringsToPaint.Length; i++)
        Size size = TextRenderer.MeasureText(e.Graphics, stringsToPaint[i], 
            fonts[i], proposedSize, flags);
        Rectangle rect = new Rectangle(startPoint, size);
        TextRenderer.DrawText(e.Graphics, stringsToPaint[i], fonts[i],
            startPoint, Color.Black, flags);
        startPoint.X += size.Width;
