while referencing the rules, I noticed the weights for creatures larger than huge did not have the correct weight. Unfortunately I misplaced my document with the formula for height and weight.

So, I redid the rules with a new formula and based it off of centimeters and kilograms. Tiny is my base for weight and height.

Height is increased above tiny using:

previous height+(start height*category count)

where previous height is the height of the next smaller category and start height is the height of tiny category count is equal to the space, 1 for tiny, 2 for small, etc...

Height below tiny is:

previous height-(start height/category count)


Weight over tiny is figured:
(previous weight*2) + (previous weight+5%)

under tiny:
(larger weight/2)-(larger weight*0.15)

You can use these formulas to extend the size categories over Gargantuan

i still need to update the predefined creatures and races, I am thinking I will instead make a script tool to automate builds.
