Topic: How does weapon length change when you change the size of the weapon?

[Xavar]

RMU states that the weight of the weapon changes be a factor of 4 if you change the size of the weapon.  It doesn't say anything about the length changing.  I assume that a Huge broadsword is not still 3' long, but 12' seems excessive. 

Is this something I missed or is it intended to be in the "figure out something that makes sense" category?

It matters a bit for a Huge monster determining melee range.

The general rule discussed in beta was that length doubles and weight quadruples. I think that was just a general guideline though.

More exactly, since Size goes by a factor of 4 for weight (and hence volume), the scaling factor for linear measures is the cube root of four, which is approximately 1.6. So, that 3' Medium broadsword becomes a five foot Big broadsword, a seven and a half foot Large broadsword, and, yes, a twelve-foot long Huge broadsword for a mountain giant that stands 18-20 feet tall.

Just to add to what Dan said, it's discussed in Treasure Law, including tables with stats for small, big, and large weapons.

Thank you.  I wasn't seeing that in Treasure Law.

In the beta version, it was on page 33 of the PDF (numbered page 31).
