When a minifigure stands with its arms extended in front of it, the distance from centre to centre of its claw hands will be exactly two modules. Even so, the unique dimensional world in which minifigures exist became apparent. Half sections and half modules, or even quarter variants, are the domain of minifigures, necessitated by their need, first and foremost, to mirror human child proportions as much as possible. Raise a minifigure’s hands all the way up, the centre-to-centre dimensions of its hands equals seven and a half sections. Fully lowered, twelve- and three-quarter sections. No other element in the LEGO System is so irregular with its connection points and measurements

Because a minfigure's arms attach at an angle the distance between the hands varies based on the angle. The one regular measurement is that minifigure hands are two-modules apart when extended in front.
