TextRenderer.MeasureText Method (IDeviceContext, String, Font)


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

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

public static Size MeasureText(
	IDeviceContext dc,
	string text,
	Font font


Type: System.Drawing.IDeviceContext

The device context in which to measure the text.

Type: System.String

The text to measure.

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 in a single line with the specified font in the specified device context.

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

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;
