Nozzle Size Calculator

Calculate Your Nozzle Size

Enter your pressure washer's PSI and GPM to find the correct nozzle size.







Helpful Tips

  • Round up to the nearest 0.5 nozzle size to avoid overloading your pump.
  • Nozzle sizes are standardized in 0.5 increments (e.g., 2.0, 2.5, 3.0).
  • Too small a nozzle = too much pressure = risk of damage.
  • Too large a nozzle = lower pressure, but safer for your equipment.
  • Match the nozzle angle to your task:
    • 0° (Red): Max pressure, for tough stains on concrete.
    • 15° (Yellow): Heavy-duty cleaning.
    • 25° (Green): General-purpose cleaning.
    • 40° (White): Gentle cleaning (cars, windows).
    • 65° (Black): Soap application, low pressure.
