KEGCALC

DIAL IN YOUR DRAFT

Find your balance.

Choose your beer targets. We’ll work out the pressure and line length.

Your setup

Choose from the beer styles page →

Use the brewer’s targets when available.

Use your location’s elevation, not faucet rise. Adds about 0.5 PSI per 1,000 ft (305 m) to calculated pressure. Zero means sea level.

For a typical home kegerator, use 3/16″ ID beverage-grade vinyl. Larger bores need a system designed for them and different lengths. These presets are for beer line, not CO₂ supply hose. Match hose dimensions, fittings and clamps.

The 24-inch (61 cm) default represents a typical home tower kegerator setup. Measure upward from the middle of your keg to the faucet and adjust for your setup.

Advanced pressure settings

Faucet pressure is the pressure reserved at the faucet inlet in this estimate, not another regulator setting. KegCalc subtracts it and vertical lift loss from serving pressure, then divides by approximate tubing resistance. Start with 2 PSI (0.14 bar / 14 kPa), adjustable from 1–4 PSI (or the bar equivalent), KegCalc’s practical starting assumption based on the creator’s experience—not an industry standard or a measured pressure. Lower values calculate longer lines; higher values calculate shorter lines. This model does not predict flow rate. Line resistance is approximate; actual tubing and flow vary.

Safety

Check your equipment limits

30 PSI is KegCalc’s calculation limit, not your equipment’s safety limit. Check the manufacturer’s working-pressure limit for every part exposed to pressure. The lowest applicable limit wins—even below 30 PSI. Unknown rating? Don’t pressurize until the manufacturer or a qualified draft-system technician confirms it.

Pressure safety & limits

A starting point, then a test pour.

This calculator models equilibrium carbonation with CO₂ and approximate line resistance. It is intended for a home kegerator, not nitrogen blends or long-draw systems. Start with extra tubing and test with cold, properly carbonated beer and the faucet fully open. Aim for roughly 2 US fl oz per second (about 1 US gal/min), or 16 fl oz in about 8 seconds; highly carbonated beers may need a slower pour. If flow is too slow, shorten the line in small steps and retest. If flow is too fast, do not trim: more restriction is needed. Keep regulator pressure matched to temperature and carbonation.
