Measure Size Of Rendered Text In WPF

Problem: Get the size that arbitrary text will take to adjust width, height of a control or control wrapping.

Solution:

FormattedText formattedText = new FormattedText(text,
  Thread.CurrentThread.CurrentCulture,
  FlowDirection.LeftToRight,
  new Typeface(fontFamilyName),
  fontSize,
  Brushes.Black);
return formattedText.Width;
