 double   Double  A string representation of a Double value. This is interpreted as a device-independent unit (1/96th inch) measurement. Strings need not explicitly include decimal points. For example, a value of 1 is acceptable. The same Double range restrictions that are mentioned in the Property Value section apply here.  qualifiedDouble  A double value as previously described that is followed by one of these unit declaration strings: px, in, cm, pt.  px (default) is device-independent units (1/96th inch per unit)  in is inches; 1in==96px  cm is centimeters; 1cm==(96/2.54) px  pt is points; 1pt==(96/72) px  Note   In many cases a double may be set to Auto but a Control.FontSize does not render if set to Auto.

The following example shows how to set the font size property of a control.

        Click="ChangeFontSize">
  FontSize
</Button>

void ChangeFontSize(object sender, RoutedEventArgs e)
{
    fsize = btn3.FontSize;
    if (fsize == 16.0)
    {
        btn3.FontSize = 10.0;
        btn3.Content = "FontSize";
    }
    else
    {
        btn3.FontSize = 16.0;
        btn3.Content = "Control font size changes from 10 to 16.";
    }
