How to Choose the Right Paintbrush or Roller

How to Choose the Right Paint Brush

So you’re preparing to tackle a paint project that’s long overdue. You’ve settled on a color, gotten your paint mixed, and are picking up all the paint supplies you need: drop cloths, paint trays, rollers and frames, and paintbrushes.

At this point you realize that there are a lot of rollers and brushes out there and that their different characteristics are tough to distinguish. What type of paintbrush is best for my project? Should I use a different brush for chalk paints or interior and exterior paints? What size of brush should I use? What type of brush end should I look for and which bristle material is the best? What’s the difference in nap size and material for rollers?

These are all common and valid questions while standing in front of a display of paintbrushes. Our paintbrush guide will help you navigate and determine which paintbrush you should use and how to choose the right roller cover.

Types of Paintbrushes

Brush Shapes

Angled vs. Square-Cut

When choosing the right paintbrush, you'll often find two shapes of brushes: square or angled. Square-cut brushes have bristles (the fibers of the paint brush that apply paint) cut straight across, and best for general use and larger paint applications. Angled brushes are cut at an angle towards the tip of the brush, giving you a fine point that's perfect for detailed work like painting trim or on ceiling cut ins.

Paint brush types

Nylon/Polyester blended paintbrushes

These brushes are popular thanks to their versatility and durability. Blended nylon/poly brushes work well with all types of latex paints and, with regular care, will last for years. Nylon gives it durability and polyester gives it its shape, and both combine to give you a consistent, quality finish.

Natural-bristle paintbrushes

Natural brushes are made from animal hairs and used for oil-based paints, along with varnishes, polyurethane, or any other oil-based finishes. These soft brushes often have split or fuzzy tips, which helps apply paint or stain more smoothly.

Polyester paintbrushes

Full poly brushes are used with latex paints. They’re stiff and hold their shape well, which helps you apply paint smoothly and evenly. 

Nylon paintbrushes

Nylon brushes are typically used by professional painters for interior applications and help your paint flow smoothly off the brush. They’re typically more sensitive to heat and humidity though, and can get damaged if left in higher temperatures.

What Brush Size Should I Use?

2" brush

2" or less

Perfect for windows or other trim

3 inch brush

2-1/2" to 3-1/2"

Best for painting doors and cabinets, as well as general purpose jobs

4 inch brush

4" and up

Best for large, flat areas like walls or siding

Roller Fabric Types

Natural Roller Cover

Natural Roller Covers

Natural fabric covers are typically made with mohair or sheepskin. These types of fabric covers are to be used with oil-based paints – the water in latex paints may ruin the cover by causing them to become matted.

Blended Roller Cover

Blended Roller Covers

These versatile covers are made with a polyester/natural fiber combination. The polyester gives them excellent durability while the natural fibers apply paint smoothly. They can be used with all types of paint.

Synthetic Roller Covers

Synthetic Roller Covers

Synthetic covers are often made of nylon, dacron, or polyester. They’re ideal for most latex paints and oil-based paints.

What Does Nap Size Mean?

Rollers are often distinguished by their nap size, which is the length of the fibers that make up the roller. A smaller nap roller will have shorter, more tightly grouped fibers, while a larger nap will have longer fibers and be softer to the touch.

1/4" Nap

1/4" Nap

Good for smooth surfaces such as new walls, trim, and metal

3/8" Nap

3/8" Nap

Best for smooth or lightly textured walls


1/2" Nap

1/2" Nap

Used for most walls or slightly rough surfaces like textured plaster and some forms of concrete

3/4" Nap

3/4" - 1" Nap

Best for rougher surfaces like heavily textured walls or ceilings, as well as plaster, concrete, or stucco
