Kegerator Keg Size Compatibility: Which Fits?

Keg size names on listings

Kegerator listings name kegs in barrel fractions: half barrel, quarter barrel and sixth barrel. These names describe the relative footprint of the keg, not a measurement of the cabinet. A half barrel keg is larger than a quarter barrel keg, and a sixth barrel keg is smaller still. The names help you sort listings, but they do not by themselves tell you whether a keg will fit inside the cabinet.

Look for the keg size name next to the cabinet type in a title. A full size cabinet with a single tap often names a half barrel keg. A compact cabinet, such as a 15 inch wide model, often names a sixth barrel keg. The pairing of keg size and cabinet width is the first clue that a listing is aimed at a specific keg.

• Half barrel: the largest keg name on home listings, usually paired with a full size cabinet.
• Quarter barrel: a middle keg name, common on dual tap listings.
• Sixth barrel: the smallest keg name, paired with compact and undercounter cabinets.

How to verify interior dimensions

The reliable way to know which keg fits is to compare the interior dimensions stated in the listing with the keg you plan to use. A listing usually states exterior width, height and depth; interior dimensions may appear in the bullet list below the title. Look for words such as interior height, interior depth and usable width. This is the same dimension planning you would do for any cabinet.

Interior height matters most for a tall keg: the keg must fit below the top of the cabinet with room for the coupler and the lines attached. Interior depth matters for a keg that sits toward the back. Usable width matters when two kegs share one cabinet.

When a listing states only exterior dimensions, compare those with the space where you plan to place the cabinet. Then ask the seller for the interior measurements before you buy.

What a listing may not say

Many listings name a keg size but do not state every interior dimension. A title that says it fits a sixth barrel keg tells you the design intent, not the exact clearance. Some listings omit interior height; others state it only in the bullet list. Read the full bullet list before you assume a keg will fit. The keg types article explains the names you will see.

When the interior dimensions are not stated by the seller, treat the keg size name as a hint, not a promise. Ask the seller for the interior height, depth and width. A keg that fits by name may still be too tall once the coupler and the lines are attached.

How taps pair with keg size on listings

Taps and keg size usually appear together in a listing title. A single tap listing often names one keg. A dual tap listing names two kegs and needs enough interior width to hold them side by side. A triple tap or four tap listing implies a wider cabinet and a commercial layout. Reading the tap count tells you how many kegs the seller intends, which narrows the keg sizes that make sense.

Cabinet width is the practical link between taps and keg size. A narrow cabinet with two taps may hold two sixth barrel kegs, while a wide cabinet with two taps may hold two quarter barrel kegs. Compare the stated width and the keg size name before you settle on a tap count. The 24 inch kegerators guide shows how common widths pair with keg names.

A checklist before you buy

Before you commit to a listing, run through this checklist. These points apply whether you are looking at a full size, undercounter or conversion refrigerator.

• Read the bullet list for interior dimensions, not just the title.
• Compare the keg size name with the cabinet type: full size, undercounter, 15 inch, 24 inch or wide commercial.
• Check the door opening and the depth behind the coupler area when the listing states them.
• Ask the seller for any interior dimension that is not stated.
• Match the tap count to the number of kegs you plan to keep on draft.
• Confirm the cabinet width matches your space before you compare keg sizes.

Keg size on conversion refrigerator listings

A conversion refrigerator listing does not name a keg size by design. Instead, the listing describes the refrigerator that will hold the keg: the interior volume, the shelf layout and the door style. You read the conversion listing the same way you read a kegerator listing: the keg size name may appear in the title, but interior dimensions are what matter.

Some conversion listings state the intended keg in the title, for example a sixth barrel or a quarter barrel. Others leave it to you to compare the interior against your keg. When the title is silent, the bullet list is the only place to look for fit.

What to pick for your situation

Questions

Does a half barrel keg fit every kegerator?

No. A half barrel keg is the largest keg name on home listings. It fits only a cabinet whose stated interior height, width and depth match the keg. Read the interior dimensions in the listing instead of relying on the keg size name alone.

What is a sixth barrel keg?

A sixth barrel keg is the smallest keg size name on compact listings, such as 15 inch wide and undercounter models. Its footprint is smaller than a quarter or half barrel keg, which is why compact cabinets usually name it.

Why do some listings not state interior dimensions?

Sellers state what they choose to state. The title may name a keg size while the bullet list omits the interior height or depth. If the interior is not stated, ask the seller before buying.

Can two kegs fit in one cabinet?

Yes, when the listing states enough interior width and names two kegs, for example a dual tap listing. Compare the stated width with the combined footprint of the two kegs you plan to use.

Does a dual tap mean two kegs will fit?

A dual tap implies two kegs, but the listing must still state the cabinet width and any interior dimensions. A narrow dual tap cabinet may hold two smaller kegs, not two large ones.

Are the keg size names the same across makers?

Half, quarter and sixth barrel are common keg size names across makers. The names describe the relative footprint of the keg, so the cabinet you choose must match the name with its stated interior dimensions.
