A schooner of beer is a type of beer glass that varies in size depending on the country and region. Here are some examples:

• Australia: In Australia, a schooner is a type of beer glass typically holding 425 millilitres (or 15 fluid ounces) of beer. It is used for any type of beer and is popular in many pubs and bars, particularly in New South Wales and Queensland.

• Canada: In Canada, a schooner refers to a large capacity beer glass. Although not standardized, the most common size of schooner served in Canadian bars is 33.3 Imp fl oz / 946 ml (32 US fl oz) ).

• United States: In most places in the United States, "schooner" refers to the shape of the glass (rounded with a short stem), rather than the capacity. It can range from 18 to 32 US fl oz (532 to 946 ml) ).

Its worth noting that the term "schooner" can also refer to a type of sailing ship, and that the size of a schooner glass can vary depending on the region. For example, in South Australia, a "schooner" refers to a glass with a capacity of 285 ml (10 imp fl oz) (known as a "pot" elsewhere in Australia, or a "middy" in New South Wales and Western Australia) ).
