The easiest way I've found is:
    For the treble--use a small 150 mm steel rule with the starting end
filed to a bevel to enable the end to easily slip almost all the way up to
the termination point.
    For the lower treble--the same only in a longer length, typically 450
or 500 mm. These longer rules are usually a bit wider and more awkward to
use, hence the smaller one for the treble.
    For the agraffe section--use a tape measure. Check the tape for
accuracy, the hooks are not always placed properly. When buying a tape take
you steel rule with you. Place the tape hook over the agraffe and read to
the center of the bridge pins--subtract 2 mm for one/half the width of the
agraffe.

Always measure with the dampers removed or work under them.
