You could use the tape measure tool in my AnnotateWindow
program for this purpose:

AnnotateWindow, image, XRange=[0,5], YRange=[0,4]

The ranges specify the actual extent of your image data
(shown here at 4 mm by 5 mm). You can find out about the
program here:

(The angle measuring tool might also be of interest to you.)

Cheers,

David
