Depending on your kegerator, you may have the option to choose from a variety of keg sizes. To determine the right keg for your needs and kegerator, read on.
Nicknames: Bubba Keg
Typically designed for mini kegerators, however, mini kegs can be compatible with larger kegerators. This is the smallest kegerator size often available and this keg contains 5 liters or 169.07 ounces.
This size keg is perfect for one-time use or portable purposes, from tailgating or camping to small parties and events. The downside of a mini keg is that there are often limited options for beverages.
Common Uses: One Time-Use, Travel & Portable Applications, Small Batches, Single Tap Kegerators
Dimensions: 9⅞” x 6¾”
Capacity: 1.75 gallons / 224 ounces
Pints (16oz) per keg: approx.14 pints
Nicknames: Corny Keg, Homebrew Keg, Soda Keg
Originally designed for soft drinks, it allowed the soft drinks to have the ideal proportions of flavoring and carbonation. This keg is now commonly used by homebrewers as an alternative to bottling beer because this keg size is the typical size of a homebrew batch, 5 gallons. The friend of the homebrewer, good old Cornelius is easy for homebrewers to fill, clean, and maintain than individual bottles. The top of a Corny Keg opens up completely, making it very easy for a homebrewer to easily clean the interior of the keg without special equipment.
There are two types of connectors available for the Cornelius Keg, ball-lock for more modern kegs and pin-lock for older models.
Common Uses: Homebrewing, Small Batches, Single Tap Kegerators, Dual Tap Kegerators, Triple Tap Kegerators
Dimensions: 23″ x 9″
Capacity: 5.0 gallons / 640 ounces
Pints (16oz) per keg: approx. 40 pints
Sixth Barrel Keg
Nicknames: Sixtel, Torpedo, Log, 1/6 Barrel, 1/6 BBL
While this keg may look similar to the Corny Keg, the Sixth Barrel Keg actually holds slightly more (5.16 gallon capacity vs. 5.0 in a Corny Keg). We won’t complain about getting more to drink. Unlike a Corny Keg, which uses a ball-lock or pin-lock connection, this keg uses a traditional keg valve system that requires a coupler for dispensing.
The Sixth Barrel Keg is commonly used in dual or triple tap kegerators to provide a variety of options without the need for multiple kegerators because two or three of these kegs will fit into one standard kegerator cabinet. This is ideal for restaurants, bars, and homes with limited space. For homebrewing, the Cornelius Keg is still recommended because Sixth Barrel Kegs don’t open without special equipment and cannot be cleaned easily without special equipment.
Common Uses: Single Tap Kegerators, Dual Tap Kegerators, Triple Tap Kegerators, Commercial Use, Limited Storage Space
Dimensions: 23⅜” x 9¼”
Capacity: 5.16 gallons / 661 ounces
Pints (16oz) per keg: approx. 41 pints
Quarter Barrel Keg
Nicknames: Pony Keg, Stubby Quarter,1/4 BBL
The short and stubby sibling of the keg family, the Quarter Barrel Keg is ideal for small parties and limited storage spaces. Don’t underestimate this keg because of its size, the short and stubby shape of this keg allows you to stack kegs for storage in one kegerator cabinet or refrigeration system. Unfortunately, when stacked, only one can be tapped at a time but when you have limited space, this little guy will serve you well.
Common Uses: Small Parties, Limited Spaces, Single Tap Kegerators, Dual Tap Kegerators
Dimensions: 16⅛” x 13⅞”
Capacity: 7.75 gallons / 992 ounces
Pints (16oz) per keg: approx.62 pints
Slim Quarter Keg
Nicknames: Tall Quarter, The Slim, Slim 1/4 BBL
The slimmer sibling of the Quarter Barrel Keg, this Slim Quarter Keg holds the exact same amount but has the benefits of the Sixth Barrel Keg’s slim shape. This keg is ideal for dual and triple tap kegerators allowing you to serve a variety of beverages with one kegerator. Some single tap kegerators with large cabinets can also store multiple Slim Quarter Kegs.
Common Uses: Small Parties, Limited Spaces, Single Tap Kegerators, Dual Tap Kegerators, Triple Tap Kegerators

This keg is known as your standard and traditional full-sized keg. This king of keg parties is ideal for large parties or gatherings, commercial use, and large homebrew batches. Frequently used at restaurants and bars, this large keg can also fit into most standard-sized home kegerators. For homebrewers who brew large batches, this easy to clean Half Barrel Keg with a Ball Lock is perfect for storing large beverage batches instead of splitting your batch into 5-gallon Corny Kegs.
