Conductor size is about current, not voltage, so I would expect 120V plugs to be bigger as they need to be rated yo 20A to be as useful as typical 240V/10A plugs.
Australia/NZ style plugs are much smaller than (and IMO superior to) the UK plugs despite both being 240V/10A
The plug contacts are basically never the limiting factor current wise. They are massive solid metal prongs, they can easily handle 20-30 Amps without getting too hot. The cable will always be limiting factor for current.

iiiinteresting. good to know my whole house is a fire hazard by UK standards!
