The height of the em square.

Em square is a typography term that refers to the rectangle occupied by the font's widest letter, traditionally the letter M.

The following code example is designed for use with Windows Forms, and it requires PaintEventArgse, which is a parameter of the Paint event handler. The code performs the following actions:

  • Creates a FontFamily.

  • Gets the em square height for that font family.

  • Draws the value of the em height to the screen as text.

public void GetEmHeight_Example(PaintEventArgs e)
    // Create a FontFamily object.
    FontFamily emFontFamily = new FontFamily("arial");

    // Get the em height of the font family in design units.
    int emHeight = emFontFamily.GetEmHeight(FontStyle.Regular);

    // Draw the result as a string to the screen.
        "emFontFamily.GetEmHeight() returns " + emHeight.ToString() + ".",
        new Font(emFontFamily, 16),
        new PointF(0, 0));
