Use this keg carbonation calculator to turn your fridge or kegerator temperature and desired carbonation level into the correct CO₂ regulator setting. Choose a BJCP beer style or enter your own volumes of CO₂ and get an instant keg PSI recommendation.
This tool uses a standard forced-carbonation equation and typical style carbonation ranges. Always fine-tune by taste and based on your draft system behavior.
Kegging your beer raises a big question: what keg PSI do you use for a given beer style and temperature? Classic homebrew books publish a printed beer carbonation chart, but this page acts as an interactive version of that chart. Instead of squinting at a table, you enter your kegerator temperature and target carbonation level, and the calculator returns the correct beer serving pressure in PSI.
Carbonation is measured in “volumes of CO₂.” One volume means your beer contains an amount of dissolved CO₂ equal to its own volume at standard conditions. Low-carbonation cask-style ales are usually 1.5–2.0 volumes, most American ales and lagers sit around 2.2–2.6 volumes, and highly sparkling styles like German wheat beers and many Belgian ales can be 2.6–3.5 volumes or more. This keg carbonation calculator converts those volumes of CO₂ into a practical keg PSI setting.
Use these ranges as a quick reference beer carbonation chart. Exact PSI will depend on your fridge temperature, so plug the numbers into the calculator for precise results.
If you are searching for a beer carbonation chart or wondering “How much should I carbonate this beer style?”, you can use these ranges along with the calculator to set the right keg serving pressure for your system.
Printed carbonation tables are handy, but they are limited to a few temperatures and can be hard to read on a phone. This tool works as a dynamic beer carbonation chart. Enter the exact temperature of your keg, choose a beer style to prefill a recommended carbonation level, and the calculator outputs the correct beer serving pressure in PSI.
Whether you want the ideal carbonation for an Irish stout, American IPA, German pils, or a Belgian tripel, this calculator saves you from manual chart lookups and guesswork.
Many homebrewers respond to foamy pours by lowering keg PSI, which eventually leaves the beer under-carbonated. Instead, you want to keep the correct keg serving pressure to maintain your target volumes of CO₂ and adjust line length, line diameter, and restriction to control foam. Once the beer is in equilibrium, a well-balanced system usually pours most styles cleanly at 10–14 PSI at typical kegerator temperatures.
Some brewers use “burst carbonation” with higher pressure for a short time, then drop to a lower serving pressure. This calculator focuses on the equilibrium pressure: the PSI that will maintain your target carbonation if the beer stays at a steady temperature. For force carbing, you might start higher, but you will eventually bring the regulator back to the recommended keg serving pressure shown here to keep carbonation stable over time.
If you searched for “beer carbonation chart,” “keg PSI chart,” “beer serving pressure,” or “how much pressure to carbonate a keg,” this page is designed for you. Use the calculator to:
Combined with the built-in style presets, this keg carbonation calculator replaces a static beer carbonation chart and gives you a fast way to dial in perfect carbonation for every keg.
