This is based off a lot of bug issues about equipment and the natural state of how difficult it can be to determine the exact sizes of where the limit can be for a elf for example between slipping into human or dwarf sized clothes, and who made anonymous objects for the public market.
"This is a small leather glove, it is of dwarven design"
This little addage may seem over the top just for description, but regards to game logic it really helps out.
The good people of DFhack are already chipping away at the problem of 1 handed glove reactions for instance with the additional logic that the script always determines how many hands the maker has. The 8 armed 16 handed spider-people for instance make gloves in batches of 8 left hands and 8 right hands of spider-people design.
It also extends as a homage of working out a object's origins. A mysteious spear forged by the dwarves long ago before their inexplicable demise may not be particular interesting to the game-world without a bit of worldbuilding but may still be desirable for a player adventurer to arm themselves in culturally significant objects.
Other evidence also points to sizing of objects, a screenshot generously plucked from discord where a member of that community had some demons manufacture armor, being rendered technically armor, created a 1600 unit heavy shield out of the same common materials as a dwarven shield.

This large shield, personalized to its owner is most noteworthy of being of demonic design.
