The thickness of roller covers is called the nap or pile. A rule of thumb to follow is that the rougher the painting surface, the thicker the nap you should use. Roller covers are typically available in thicknesses of 3/16 to 1/4-inch, 3/8 to 1/2-inch, 3/4 to 1-inch and 1 1/4 to 1 1/2-inch, each designed for a different purpose.
3/16 to 1/4-inch thickness is perfect for smooth surface roller covers for painting metal doors, interior doors, trim and cabinets. They work well with semi-gloss or gloss coatings and both oil- and water-base enamels.
3/8 to 1/2-inch thickness is preferable for semi-smooth surfaces such as drywall. It can be used on painted or unpainted walls and ceilings.
3/4 to 1-inch thickness is suitable for stucco and other semi-rough surfaces.
1 1/4 to 1 1/2-inch is ideal for rough surface roller covers for painting brick and masonry, cinder blocks or chain link fences.
Roller covers are available in two types:
Natural roller covers, made with mohair or lambswool, are ideal for oil-based paint.
Synthetic roller covers, made with nylon, polyester or a combination thereof, are best for water-based paint.
For latex paint, use synthetic materials only. For oil-based or alkyd paints, use either synthetic or natural materials. As with brushes, it's always a good idea to check the manufacturer's recommendations before purchasing paint rollers.
Nap, or pile, is the length of the roller's painting surface. Lengths will vary from 1/16 inch to 1-1/2 inches. If you're painting a smooth surface, choose a short-napped roller. For a rough surface, such as masonry, use a longer nap. Rollers with textured surfaces are also available for special finishes.
Rollers come in widths from 4 to 18 inches. The metal frame for the roller cover comes in two types: birdcage and metal. The birdcage frame works better if you're using fast-drying paints, as it's easier to clean than the solid metal type. Most handles are made for attaching an extension.
Trim rollers come in varying shapes and sizes. Cone-shaped types work well for inside corners. Doughnut-style rollers are good for mouldings and other detailed work.
Consider a mini paint roller when painting woodwork, small areas or in tight spaces.
You can use textured paint rollers for aesthetic appeal. They provide a textured look to a wall and are a good choice to cover up imperfections on dry walls.

Whether you're a professional or someone who enjoys do-it-yourself (DIY) projects, getting an impressive faux finish has never been easier. Consider a faux finish roller for an added dimension to your paint job.
When Purchasing a Roller:
Look for beveled edges on the roller. These create a smooth finish.
Check to make sure the roller has no visible seams.
Give the roller a squeeze to check that it rebounds to its original shape.
Roller Tips
Moisten the roller with water or thinner before using it to prevent paint from drying on it.
Load the roller with paint from the slanted edge of the tray to prevent overloading.
Paint in the shape of the letter W. Start by moving the roller away from you. Without lifting the roller from the wall, fill in the open space.
Don't try to paint too quickly.
To clean a roller cover, roll it back and forth on newspaper. Remove paint with the proper thinner. If you're rinsing out solvent-based paint, wear rubber gloves. Let the roller dry before storing it.
Disposable rollers are available. If you don't plan on repainting soon, you may want to use these to avoid cleanup ' especially if you're using oil-based paint.
