Dynamically resizing font to fit space while using Graphics.DrawString

Question

Does anyone have a tip whereas you could dynamically resize a font to fit a specific area? For example, I have an 800x110 rectangle and I want to fill it with the max size f

Here is my solution that support wrapping.

public static Font GetAdjustedFont(Graphics graphic, string str, Font originalFont, Size containerSize)
    {
        // We utilize MeasureString which we get via a control instance           
        for (int adjustedSize = (int)originalFont.Size; adjustedSize >= 1; adjustedSize--)
        {
            var testFont = new Font(originalFont.Name, adjustedSize, originalFont.Style, GraphicsUnit.Pixel);

            // Test the string with the new size
            var adjustedSizeNew = graphic.MeasureString(str, testFont, containerSize.Width);

            if (containerSize.Height > Convert.ToInt32(adjustedSizeNew.Height))
            {
                // Good font, return it
                return testFont;
            }
        }

        return new Font(originalFont.Name, 1, originalFont.Style, GraphicsUnit.Pixel);
    }

How to use:

var font = GetAdjustedFont(drawing, text, originalfont, wrapSize);
drawing.DrawString(text, font, textBrush, new Rectangle(0, 0, wrapSize.Width, wrapSize.Height));
