It depends on the species of wood the joists are made from but it should be in the low 11 to mid 12 foot range. Note that the span is the distance between the inside edges of the end supports, so a 12' joist on 2x4 walls will actually span only 11'5" (12 - 3.5 -3.5)
Arm span is approximately equal to a person's height. So the predicted height of a person with an arm span of 66in is also 66in.
