size system
The system a product's size values are expressed in — US, UK, EU (or DE/FR/IT/JP), International, alpha (XS–XXL), or numeric — so that a bare value like '42' is unambiguous (EU shoe vs UK shoe vs waist measure). A flat listing-level token (cardinality one: a listing expresses its sizes in one system), not a per-size qualifier and not a SKU-grid host (A9). Universal: sizing systems span every sized kind. Optional at the pool floor; absent for kinds whose size scale is self-identifying (battery, bedding).
Size system is answered with one word chosen from the size systems list — the same word shared across every product that uses it.
It belongs to variation — one facet of a product.
