Both are know as 1/2 inch tap washers but both measure more than 1/2 inch
(12.7mm). As close as I can measure with my ruler:
As I understand it, the " half -inch' refers to the bore of the water
pipe with which they are associated - and includes three-quarter and
one-inch as part of the series.

A typical "half-inch" tap washer in the past would measure perhaps
three-quarters of an inch dia., but in more recent times the
proliferation of fancy bathroom ware has given rise to a variety of
custom taps (faucets) with their own washers.

My own houshold taps ( I'm told ) have ceramic washers which ( I'm
told ) never wear out and ( I know ) are drip-free.
