the.com/size

means A measurement of how big something is, especially one used to sort clothes, portions, or objects into standard categories that promise consistency and rarely deliver it.

from From Old French 'sise,' a shortening of 'assise' — meaning a sitting, session, or setting of a rule — the same root behind 'assize,' the sessions where courts fixed official standards and regulations. 'Size' originally meant an officially fixed amount or standard, like the regulated measure of bread or ale. So the word has always been about imposed order, some authority declaring 'this is the standard' — which makes it almost poetic that sizing has never actually standardized anything.
