Choosing the wrong nozzle size is one of the fastest ways to lose pressure, damage equipment, or just waste time on the job. It's not complicated but a lot of people guess. Guessing is what causes problems. 

The Two Numbers That Matter: PSI and GPM

Every pressure washer is built around two things:

PSI (pressure) = what breaks dirt loose

GPM (flow) = what rinses it away

Your nozzle is what balances those two.

The size of the opening (orifice) in your nozzle directly controls how much pressure and flow you get.

Smaller nozzle = more pressure, less flow

Larger nozzle = less pressure, more flow

Why Nozzle Size Matters

If your nozzle is wrong, you’ll notice it immediately:

Low pressure? → Nozzle too big

Machine struggling? → Nozzle too small

Cleaning takes longer? → Wrong setup

Using the wrong nozzle can:

Reduce efficiency

Overwork your pump

Cause premature equipment failure

How to Actually Pick the Right Nozzle

There’s a formula, but you don’t need to memorize it:

Nozzle Size = GPM × √(4000 ÷ PSI)

Instead, most contractors use a chart.

Simple Way to Do It:

Find your machine’s PSI

Find your GPM

Match them on a nozzle chart

That gives you your correct orifice size

Example:

4 GPM @ 3000 PSI → ~4.5 nozzle
