<p>Here is a method I use for BIRT engine side (example attached).</p>
<p>*Please note that this is not 100% accurate as other factors can effect the output.</p>
<pre class="_prettyXprint _lang-js">
importPackage(Packages.java.awt);
importPackage(Packages.java.awt.image);

var str = ""+row["CUSTOMERNAME"];

var font = new Font("Sans Serif", Font.PLAIN, 10);
var img = new BufferedImage(1, 1, BufferedImage.TYPE_INT_ARGB);
var fm = img.getGraphics().getFontMetrics(font);
var width = fm.stringWidth(str);

this.text = width +"px";
</pre>
<p>If you are needing to measure text via the rendering side (HTML, PDF, etc), you will have to use other methods for calculating text length.</p>
