Keg Sizes Detailed:

While the comparison chart above gives you a quick way to compare different sizes of kegs against others, below we have gone into more detail on each type of keg.

Mini Keg

Mini Keg:

Designed for mini kegerators, this size keg only holds 5 liters of beer, or 169.07 ounces to be exact.

This is the perfect sized keg for one-time use and/or portable purposes. This may include watching the game with a couple of friends, weekend camping trip or a small dinner party with family.

  • Nicknames:  Bubba Keg
  • Common Uses:  One-time Use, Portable Applications
  • Dimensions:  9⅞” x 6¾”

Cornelius Keg

Cornelius Keg:

Commonly used by homebrewers as an alternative to bottling their beer, Cornelius kegs were originally developed by the soft drink industry.

While Pepsi and Coca-Cola both have uses for them, they have grown in popularity by those that brew their own beer or soda from home. They are easy to fill up and clean.

There are two types of connectors that are available for the Cornelius keg, including ball-lock and pin-lock. Both have different connectors that you would need to become familiar with.

  • Nicknames:  Corny Keg, Homebrew Keg, Soda Keg
  • Common Uses:  Home Brewing
  • Dimensions:  23″ x 9″

Cornelius Keg

Sixth Barrel Keg:

Commonly used for personal use in dual or triple-tap kegerators, the sixth barrel is roughly the same size as the Corny Keg, just slightly larger. This smaller sized keg functions just like their larger counterparts with the only difference being that it holds less beer than other types of kegs.

This size keg is also a great choice for restaurants and/or bars that have little space, but want to have a large variety of beer available for customers.

  • Nicknames:  Sixtel, Torpedo, Log
  • Common Uses:  Dual-Tap Kegerators, Home Brewing, Individual Use
  • Dimensions:  23⅜” x 9¼”

Quarter Barrel Keg:

Quarter Keg

Short and stubby in size, the Quarter barrel keg is the same width (16⅛”) as a full barrel, yet approximately 10″ shorter in terms of height.

Commonly called a “Pony Keg” or a “Stubby Keg,” this popular keg size will hold the equivalent of sixty-two pints or eighty-two bottles off beer.

  • Nicknames:  Pony Keg, Stubby Quarter
  • Common Uses:  Small Parties
  • Dimensions:  16⅛” x 13⅞”

Slim Quarter Keg

Slim Quarter Keg:

The Slim Quarter holds the exact same amount of beer as the aforementioned Quarter barrel, however, the over shape and size resembles the sixth barrel keg. This variation in size makes it a popular choice for anyone with a dual-tap kegerator.

With a tall and skinny build, the Slim Quarter is the same height as the Sixth barrel, but has a slightly larger width. This extra width allows it to hold an extra two gallons, which equals an extra 27.5 bottles of beer.

  • Nicknames:  Tall Quarter, The Slim
  • Common Uses:  Dual-Tap Kegerators; Small Parties
  • Dimensions:  11⅛” x 23⅜”

Half Barrel Keg

Half Barrel Keg:

When you think of your average beer keg, the Half barrel size is probably what comes into your mind. Undoubtedly, you’ve probably seen this size keg at a party or large event.

This full size keg is the largest that is available to you, and what is commonly used in bars and restaurants across the world. Most home kegerators will fit this size keg, however, the smaller versions are typically more popular amongst beer drinkers.

  • Nicknames:  Full Size Keg, Barrel of Beer, Full Keg
  • Common Uses:  Home Bar, Large Events, Business, Frat Parties
  • Dimensions:  16⅛” x 23⅜”

    Jeff, I just purchased quick connect so I can switch readily between cornies and conventional halves and quarters. Unfortunatlely my tall 1/4 of Yeungling is too tall for the kegerator with the quick connect. Are their shorter quick connects that may solve my problem? other suggestions? thanks!

    • Mike says

      Sorry for the late response. If you have not already found a solution to your issue, we will be carrying a 90 degree elbow that you can connect to the top of the commercial coupler that should give you the necessary clearance to attach the quick connect at a 90 degree angle. Please check back on our site in the couplers section soon.

    Thanks for this list of different sized kegs. Very handy. I always thought that there was only one size. The full barrell.

  3. Paul says

    I recent bought a 6 ft.³ single tap kegerator and need to know what size keg is the best size to use. Any suggestions?

    • John Straight says

      Some are and some are not. Heineken and New Castle have a self- contained pressure source, which makes them not reusable without some major modification. Many European imports use external pressure sources or no pressure to push beer. These kegs can be reused. This type can be purchased from a number of on-line brewing suppliers.

    With the holiday fast approaching we want the exhilaration of drinking ice cold nectar from a keg for maximus festivas 😉 We are having a few guests and have reserved a sixth barrell but the looming thought when having a keg is that when friends and neighbors “get wind” there is always a chance that a few stragglers will pop in making this size keg seem inadequate.

    We have a small fridge that could convert into a kegerator but we dont have the necessary equipment which leads to my question, if we decided to go with a quarter or half barrell is it possible to use a disposable smaller sized co2 like the approx. 30 ounce size they use for paintball guns that they sell at Wa*%#rt for $20 so we may be able to preserve the unused beer for more than 24 hours and would a disposable tank be compatible with the pump style taps that the package stores offer?

    I spoke with the distributor and several package stores and the prices I was quoted for co2 tanks and conversion kits from recommended local retailers were such that I would find better value in purchasing a brand new kegerator which is why I would be thrilled if this other idea could work. One of the reviews that I read for the 30 ounce tank the customer mentioned that he was going to use it for a beer keg. I also read that a traditional lager normally needs 10-12 psi of co2 pressure and a 5 pound (90 ounce) co2 tank will usually last for 2-4 half barrells depending on temperature conditions. The alternative is to dump the unused beer if we end up just packing it on ice because it will turn sour on Sunday without the co2. Package stores/distributors should offer the co2 option even if you just stick it in a regular refrigerator during or after your party/event.

    Any input would be appreciated. Thank you

    My Kegerator is double tap but can hold 3 1/6 kegs (one for reserve). I’m struggling because I’ve always kept bud light on tap plus one better beer. For the life of me I can’t find bud light in a 1/6, only bud. Is it an urban legend? Lastly, have you ever seen somebody pull off stacking two 1/4 kegs in a kegerator, running the beer line through the handle??
