- Pick a keg size: half barrel, quarter, sixth barrel or corny keg.
- Set the pour size, such as 16 oz for a pint or 12 oz for a cup.

Frequently asked questions
How many beers are in a keg?
A half barrel keg holds 1984 oz, which is 124 pints at 16 oz or about 165 twelve-ounce cups. A sixth barrel holds 661 oz, and a corny keg holds 640 oz, so each gives roughly 40 pints.
What are the common keg sizes?
A half barrel is the full-size keg at 1984 oz, a quarter barrel or pony keg is 992 oz, a sixth barrel or sixtel is 661 oz, and a corny keg used by homebrewers is 640 oz, about five gallons.
How many kegs do I need for a party?
Estimate total servings, then divide by servings per keg and round up. For 300 pints from half barrels that pour 124 each, you need three kegs. Plan a buffer if guests drink faster early on.
Why are real-world pours often a bit less than a full pint?
Foam and head space mean a 16 oz glass usually holds about 14 to 15 oz of beer, so kegs can serve more glasses than the math shows. This tool counts whole pours at the size you enter.
Does the tool count partial servings from a keg?
No. It counts only whole pours, so leftover beer that is less than one full pour is not assumed to serve anyone. Kegs needed is rounded up so there is enough for everyone.
