Upsize → It is formed from "up" (meaning to a higher position or level) and "size" (from Old French *size*, meaning dimension or magnitude). The word "upsize" means to increase in size or to make something larger.
Think of moving something to a 'higher position' ('up') in terms of its 'dimension' ('size') — that's why upsize means to make something larger.
