A schooner of beer is usually 425 ml , but it can vary by region.

Standard schooner size

  • In most of Australia, a schooner is 425 ml (about 15 fluid ounces).
  • This is roughly three-quarters of an imperial pint.

Important regional differences

  • In South Australia, a “schooner” often means a smaller 285 ml glass, similar to what other states call a middy or pot.
  • In Canada, a schooner is larger than a pint and commonly around 946 ml, so the word refers to a big glass rather than a fixed size.
  • In parts of the United States, “schooner” can mean a rounded glass shape and may range roughly from 532 ml to 946 ml, not one strict volume.

Quick takeaway

  • If you’re in most of Australia: expect about 425 ml in a schooner.
  • If you’re in South Australia: a schooner may only be 285 ml.
  • Elsewhere (Canada, US), always check the menu, because “schooner” isn’t a fixed millilitre amount.
