What version and code did you use? I used this:


import java.io.IOException;
import java.net.URL;
import org.apache.pdfbox.cos.COSName;
import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.pdmodel.PDPage;
import org.apache.pdfbox.pdmodel.font.PDFont;

public class Buir
{
     public static void main(String[] args) throws IOException
     {
         PDDocument doc = PDDocument.load(new 
URL("http://www.buir.de/ABCD.pdf").openStream());
         PDPage page = doc.getPage(0);
         PDFont font = 
page.getResources().getFont(COSName.getPDFName("F1"));
         float w = font.getStringWidth("%");
         System.out.println("w: " + w);
         doc.close();
     }
}

output:


w: 833.0
