Check for places that mark capacity on their glasses. Typically you can find places that do half liters, which is ~1.06 pints (thus a hair below 17 ounces). Some places have glasses marked at 16 ounces and some at 20 ounces. Glasses with beer and brewery logos on them are almost always 16 or 17 ounces. If you get a pitcher, check the bottom for a number, such as 60 or 64 (as in ounces).
Two of the world's biggest glassware makers, Libbey and Cardinal International, say orders of smaller beer glasses have risen over the past year. Restaurateurs "want more of a perceived value," says Mike Schuster, Libbey's marketing manager for glassware in the U.S. Glasses with a thicker bottom or a thicker shaft help create the perception. "You can increase the thickness of the bottom part but still retain the overall profile," he says.
Clearest proof yet we're in an economic contraction. The U.S. needs a pint law! Ah, the benefits of monarchy...
13 & 14 ounce glasses, along with 50 or 52 ounce pitchers are a plague.
Let commercialism speak for shrinking glasses. If you find a place serving these sizes without telling you prior, let the management know you are upset and claim you will never patronize their establishment until they fix the problem. If you are bold, get up and leave before drinking claiming the product served was not what you ordered.
