A beer stein typically holds one liter, which is equivalent to approximately 33.8 fluid ounces. In comparison to pints, this means a stein contains a bit more than two US pints (32 fluid ounces total) and just under two UK, or "Imperial," pints (40 fluid ounces total). So, while a stein is close in volume to two pints of beer, whether it surpasses, matches, or falls short depends on the regional definition of a pint being used.
