Outsize → It is formed from "out-" (meaning beyond or outside) and "size" (from Old French *size*, meaning measurement or dimension). The word "outsize" refers to something that is beyond the usual size or larger than normal.
Think of something that is 'beyond' ('out-') the usual 'measurement' ('size') — that's why outsize means larger than normal.
