When the amount of overlap is half of the original image, you can also consider only half the size (15px in this case) and the last one as a double image, so you get 15px * 6 = 90px.

With Z Swords it ends up covering most of it, but we're all way too familiar with those icons, plus the last one is shown in its entirety, so luckily there's no problem.
