make the smaller on 'Z' and relate to the larger as twice this size, three times this size, etc. (what ever applies)

wrench one (the smallest) = 'Z' half the size of the other
wrench two ( twice size) = "2Z' twice the size of the other
------------------------------------------------------------------------------
wrench two : ' Z/1 ' twice the size of the other
wrench one ' Z/2 ' Half the size of the other
------------------------------------------------------------------------------
