The number of pints in a keg of beer leans on both the size of the keg and the type of pint being used, as pint measurements vary between countries. In the USA, a pint is defined as 16 ounces (473 milliliters), while in the United Kingdom, a pint is larger at 20 ounces (568 milliliters). Because of this difference, the number of pints in a keg can vary depending on where you are and how you’re measuring.

The most common keg in the United States is the half-barrel keg, which holds 15.5 gallons or approximately 58.67 liters of beer. When using the american pint measurement, this equates to roughly 124 pints (15.5 gallons × 8 pints per gallon). If you were to use UK pints, you would get fewer servings—about 103 UK pints from the same keg.

Furthermore, there are also other keg sizes. A quarter-barrel keg (7.75 gallons) holds about 62 U.S. pints, and a sixth-barrel keg (5.16 gallons) holds around 41 U.S. pints. A Cornelius keg, commonly used for homebrewing, holds 5 gallons, which gives approximately 40 U.S. pints.

In Europe and the United Kingdom, keg sizes are typically given in liters. A standard 50-liter keg will yield around 88 UK pints or roughly 106 U.S. pints, depending on how it's poured. Smaller 30-liter and 20-liter kegs will give proportionally fewer pints.

Keep in mind that in real-life situations, you may waste a few pints due to foam, spillage, or over-pouring. Nonetheless, kegs remain a convenient and cost-effective way to serve beers, particularly at events, bars, and gatherings where large quantities are needed.
