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.
