    It depends on what you mean here. I’m assuming you mean you want to do it without receiving a HeadlessException.

    The best way is with a BufferedImage. AFAIK, this won’t throw a HeadlessException:

    Font font = ... ;
BufferedImage img = new BufferedImage(1, 1, BufferedImage.TYPE_INT_ARGB);
FontMetrics fm = img.getGraphics().getFontMetrics(font);
int width = fm.stringWidth("Your string");

    Other than using something like this, I don’t think you can. You need a graphics context in order to create a FontMetrics and give you font size information.
