You could place markers on opposite sides of the density contour surface, then measure the distance between the markers.
For marker creation/placement, see Volume Tracer (in menu under Tools… Volume Data):
For distance measurement, markers are treated the same as atoms. One way to do the measurement is to Ctrl-click on one marker to select it, then Shift-Ctrl-doubleclick on the other one to also select it and show context menu with a choice to measure the distance.
I hope this helps,
