16 gallon keg dimensions measure 15 1/4 inches diameter x 23 1/2 inches high. Beer servings will depend on the glass size. 16 oz = 150 beers; 14 oz = 182 beers; 12 oz = 216 beers and 10 oz = 256 beers.
The majority of US brewers make their beer in several sizes. The most common are between 5 and 6 gallons (1/6 barrel), 7 and 8 gallons (1/4) and 14 and 16 gallons (/2 barrel). However, keg specifications are not regulated. That is why kegs cannot be used as a liquid measuring standard. Standards differ from country to country. While the US measures in gallons, other countries rely on the metric system.
A 15.5 U.S. gallon barrel is equal to a full keg. It is known as a half barrel, and just a bit less than 16 gallon keg dimensions. As a rule kegs are not as big barrels. A full keg is also known as a half barrel. The 15.5 US gallon keg is the same as 1,984 fluid ounces (U.S.), 5.5 30-racks of 12 fl oz cans, 12.7 Imperial gallons, 90 bombers (a 22oz bottle) and 124 U.S. pints.
Euro Keg and Others
Sizes used here are different. The most common keg dimensions are 50 liters. In the UK the standard measurement is 11 imperial gallons. This is almost equivalent to 50 liters. However, the UK keg system is not metric based. In Germany, the DIN 6647-2 and DIN 6647-1 correspond to 20 and 30 l respectively.
More Facts about Kegs
The traditional wood keg is constructed by a cooper utilized for transporting gunpowder, nails and different types of liquids. Modern kegs are made of steel or aluminum. Its main function is to serve beer, transport and store beer. However, kegs can also be used to store other drinks (alcoholic, non-alcoholic, non-carbonated, carbonated).
16 gallon keg dimensions or not, kegs are almost always built of stainless steel. On rare cases you will find some made from aluminum. Kegs have one opening at the end. A spear / tube goes up off the opening onto the other end.
A coupling fitting is used to open the valve. The top of the spear has an opening so gas can come out. Beer and gas flow is controlled by one or two valves. To dispense the beer, the keg has to be upright so beer can be dispensed.
