Talk:Extra Player and Weapon Sizes (5e Variant Rule)

Player Weight Note

Refer to the following example as explanation for the rule presented:

A cube with a side of 10cm and a mass of 1000g has a density of 1g per cubic centimeter.

10cm*10cm*10cm = 1000 cubic cm

mass = 1000g

1000g/1000cm = 1g/cm

If the same cube's sides are ten times longer, 100cm, and it has the same density, what does its mass become?

m/100cm^3 = 1g/cm (m=?)

Simply by resolving the volume calculation, it becomes easy to see, in the example, what the new mass would be.

1,000,000g/1,000,000cm = 1g/cm

Therefore, if a player character with a given density (which should be considered a constant across size categories - the exact number of which is irrelevant so long as it is understood to remain the same) increases their dimensions from a single square to four of them - a 5ft tall character becoming 10ft tall - then their weight should also be doubled to maintain overall proportion and density. --Max7238 (talk) 21:27, 2 January 2020 (UTC)
