A pony keg is a quarter barrel: one quarter of a 31 gallon US beer barrel,
or 7.75 US gallons. Confusingly, "pony keg" is also a regional term in Ohio
and Kentucky for a drive-through beer store — this guide is about the container.
Quick answer
1 pony keg (quarter barrel) = 7.75 US gallons = 29.34 litres = 992 US fl oz,
which pours about 62 pints (16 oz) or 82 bottles (12 oz).

Two shapes, one volume
- Squat quarter (the classic pony): 13.9 in tall × 16.1 in wide. Short and
fat — it fits under a bar top but not in a narrow kegerator.
- Slim quarter (tall quarter): 23.3 in tall × 11.1 in wide. Same 7.75
gallons in a half-barrel-height body, so it fits most kegerators.
Both hold exactly the same beer. Ask the distributor which shape you are getting
before you plan the space.
When a pony keg is the right call
A quarter barrel is the honest choice for 25–35 guests over an evening: about 82
twelve-ounce servings. Below that a sixtel wastes less; above 50 guests a half
barrel is cheaper per pint and only one keg to chill.
Key takeaways
- 7.75 gallons — exactly half a half barrel.
- Squat and slim quarters hold identical volume in different shapes.
- 87 lb full: heavy, but a one-person lift for most people.
