The characteristic SIZ averages height and weights into one number. To see over something, to squeeze through a small opening, or even to judge whose head might be sticking up out of grass, use Size. Size helps determine hit points and the damage bonus. One might decrease SIZ to indicate loss of limbs, through lowering DEX is more often the solution. Presumably if investigators lose all SIZ, they disappear – goodness knows to where.
Mythos Comparative Sizes
This table equates approximate weight with game SIZ. In Call of Cthulhu, SIZ pertains not only to weight but to volume and height as well. This table should not be relied on absolutely: it will not useful for creatures lighter than air, gaseous, able to change mass, or made of plasma or ectoplasm. From SIZ 330 on, SIZ is exactly 1/10th the creature’s weight in short tons. Thus, a dhole of SIZ 8000 weights 80,000 short tons.
