Choosing the right spray tip size is key to achieving the perfect spray pattern and finish. Each spray tip is labelled with a three-digit number (like 515, 313, etc.), which tells you two important things: the width of the spray fan and the size of the orifice (opening) that the paint flows through.
The first digit (e.g. the "5" in 515) indicates half the width of the spray fan when the gun is held 12 inches from the surface.
The last two digits (e.g. the "15" in 515) refer to the orifice size in thousandths of an inch.
Example: A 515 tip creates a 10-inch fan and handles medium-thickness materials-making it a great general-purpose choice for walls, ceilings, and fences.
The best tip size depends on two main factors: the type of paint you're using and the surface you're spraying.
These create narrower spray patterns for detailed work and light coats.
These allow a higher flow rate to handle dense coatings and large surfaces.
Always check the paint manufacturer's advice for compatible tip sizes based on viscosity.
Using the correct tip ensures smooth coverage, minimal overspray, and professional-looking results. Ready to get started? Browse our full range of spray tips to find the perfect match for your project.
