How fat is this dwarf?

According to the wiki's page on weapons and size, dwarves must meet a certain minimum body size before they are capable of wielding many weapon types. This has thrown an entirely new, unexpected level of complexity into forming a militia, as the only references to a dwarf's size I can find are limited to vague adjectives such as "large", "thin", or "massive".

How can I precisely determine the size of my dwarves so I can draft the most effective servicedwarves? I'm not averse to using external methods such as DFHack.

Solution 1:

Size is something that is not currently viewable in the vanilla game, nor is it precisely understood how the various size strings, (e.g., "rippling with untold amounts of lard" vs. "gigantic build, but very skinny") stack up.

External and 3rd party applications can potentially read this data, and in some cases, change it. Runesmith was one such utility, but it is far from being up to date, and I don't know of any more recently updated utilities that allow what you're looking for.
