I did not find a table in the new Runequest rulebook that indicates how big a character is of a certain size. I found that disappointing. I made my own size and weight tables for a game system I was developing, but this departs from traditional runequest in the following ways:

* Standard human sizes run from 3-18.

* Small characters have a negative size.

* A size difference of 30 equates to one size category in D20.

I used a simple formula for translating Size to Weight:

Weight in pounds = 80*2^(Size/10).

If you prefer Metric, then you can use:

Mass in kg = 36*2^(Size/10)

Height was determined from the cube root of weight and the average height of 70 inches. So a change of 10 in Size equals a doubling of weight, and a change of 30 equals a doubling of height.

Height in inches = (Weight in pounds/160)^0.3*70.

(Height in cm could be calculated similarly.)

I think the MRQ mechanics still will work. The main difference is that the size ratings of nonhuman creatures would have to be modified accordingly.

Size and weight values from my spreadsheet:

Code:

```
SIZE WEIGHT MASS HEIGHT
3 98 lb 44 kg 61 inches/154 cm
6 121 lb 55 kg 64 inches/162 cm
9 149 lb 67 kg 69 inches/175 cm
12 184 lb 83 kg 73 inches/185 cm
15 226 lb 102 kg 78 inches/198 cm
18 279 lb 126 kg 83 inches/210 cm
```

Which explains how come I want to provide a -4 adjustment for females' Size.
