Keg Carbonation Calculator (Set-and-Forget PSI + Line Length)
Free keg carbonation calculator: enter beer temp and CO2 volumes to get regulator PSI — 2.5 vols at 38°F = 11.2 psi — plus balanced beer line length.
Keg Carbonation Calculator
Regulator Setting
11.2 PSI
Balanced 3/16″ Beer Line
≈4.7 ft
Time to Equilibrium
5–14 days
ℹ️ Set-and-forget: set this PSI at your fridge temperature and CO₂ reaches equilibrium in about a week. Line length assumes 3/16″ ID vinyl at ~2.2 PSI per foot of restriction — the reason kegerators pour better with 8-10 ft of line than the 5 ft they ship with.
