TextRenderer.MeasureText Method (String, Font, Size)

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

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

public static Size MeasureText(
	string text,
	Font font,
	Size proposedSize
)

Parameters

text
Type: System.String
The text to measure.
font
Type: System.Drawing.Font
The Font to apply to the measured text.
proposedSize
Type: System.Drawing.Size
The Size of the initial bounding rectangle.

Return Value

Type: System.Drawing.Size
The Size, in pixels, of text drawn with the specified font.

The MeasureText method uses the proposedSize parameter 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.

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;
    }

}
