Paint rollers are ideal for large, flat surfaces as they are faster and provide a smoother finish compared to paintbrushes. The most common sizes for interior jobs are 7 and 9 inches wide. The type of roller cover you should buy depends on the kind of paint you'll be using, the size of the area you're painting, and the smoothness and desired appearance of the surface. The thickness of the roller cover's fibres, also known as the nap or pile, varies from 1/16 inch to 1 and a half inches. For rough surfaces, use long naps, and for smooth surfaces, use short naps. The smaller rollers, or whizz rollers, are typically under 5 inches and are used for small surfaces and narrow areas.

Paint roller sizes: 4-18 inches wide, with 7 and 9 inches being standard
Paint rollers are a great tool for painting large, flat surfaces like walls and ceilings. They come in a variety of sizes, ranging from as small as 2 inches to as wide as 18 inches. The standard wall rollers are typically 7 to 12 inches wide, with 9-inch rollers being the most common and suitable for most home projects.
The 9-inch size is popular as it offers versatility; you can use either a 7- or 9-inch roller with it. This size is perfect for residential projects, providing good coverage and precision around edges and corners. For large wall spaces, ceilings, and expansive surfaces, a 12-inch roller can save time and energy.
For small spaces and narrow areas such as edges, corners, trim, and frames, mini rollers of less than 5 inches are ideal. These can also be used inside bookcases and cabinets. Smaller rollers of 6 to 7 inches are suitable for small furnishings or baseboard moulding.
The thickness of the roller cover, or the nap, is another important factor. The nap refers to the length of the fibres on the roller cover and affects the texture and finish of the paint job. A short nap of 1/8 to 1/4 inches is best for smooth surfaces like drywall, metal, and plaster. A medium nap of 3/8 to 1/2 inches is ideal for slightly textured surfaces like painted walls or concrete. A long nap of 3/4 to 1 inch is suitable for rough surfaces like stucco, brick, or textured drywall.

Roller covers: made of lamb's wool, mohair, Dynel, acetate, or polyurethane foam
Paint rollers are used for painting large, flat surface areas like walls and ceilings. They come in a variety of sizes and materials. The width of rollers for flat areas ranges from 4 to 18 inches, while the two most common sizes for interior jobs are 7 and 9 inches. The 9-inch size is the most popular as it provides flexibility in terms of use.
The type of roller cover is largely determined by the kind of paint you will be using. Roller covers are made of fibre or urethane foam and are labelled with the type of paint they are intended for. The length of the roller cover's nap or pile varies from 1/16 inch to 11/2 inches. For rough surfaces, long naps are used, while short naps are used for smooth surfaces.
- Lamb's wool: Sheepskin is naturally absorbent and is an excellent roller cover. It is shed-resistant and offers maximum paint pick-up and release.
- Mohair: Mohair roller covers are available in different sizes and can be used on smooth surfaces such as plaster, walls, smooth wood, and metal surfaces.
- Dynel: Dynel roller covers are made of fibres and are used to apply paint to flat surfaces.
- Acetate: Acetate roller covers are used to apply paint to flat surfaces.
- Polyurethane foam: Polyurethane foam roller covers are ideal for enamel paints, urethanes, and varnishes applied to smooth surfaces.

Nap/pile thickness: from 1/16 to 1.5 inches, with thicker naps for rougher surfaces
When it comes to painting large, flat surface areas like walls and ceilings, paint rollers are a popular choice. They are designed to help you cover more area in less time compared to paintbrushes, making them ideal for interior and exterior DIY painting projects.
Paint rollers come in a variety of sizes, with widths ranging from 4 to 18 inches. The two most common sizes for interior painting are 7 and 9 inches. The thickness of the roller cover's fibres is known as the "nap" or "pile", and it can vary from 1/16 inch to 1-1/2 inches.
For nap thicknesses ranging from 3/16" to 1/4", these short naps are ideal for very smooth surfaces like new drywall, metal doors, trim, and cabinet doors. They work well with semi-gloss or gloss coatings.
A nap thickness of 3/8" to 1/2" is suitable for smooth and semi-smooth surfaces like drywall, painted or unpainted walls, and ceilings.
For semi-rough surfaces, such as wood, stucco, or a textured ceiling, opt for a nap thickness between 3/4" and 1".
Finally, for rough surfaces like concrete block, brick, or masonry, choose a nap thickness between 1-1/4" and 1-1/2".
Remember, thicker naps are generally used for rougher surfaces as they can reach into the nooks and crannies, ensuring even coverage. They also hold more paint, which can speed up your painting process. However, they may result in a more textured finish. Shorter naps, on the other hand, are typically used for smoother finishes on flat surfaces.

Smooth finishes: use microfiber or woven fabrics to prevent lint and stippling
Paint rollers are ideal for large, flat surfaces as they help get the job done faster. They are especially useful for textured surfaces like stucco, concrete, and brick.
If you're looking for a smooth finish, microfiber rollers are the way to go. They are highly effective at absorbing liquids, especially water-based paints, and can hold twice their own volume of paint. This means less time reloading the roller and a more consistent application of paint. The smaller the lint on a microfiber roller, the more coverage it will provide. Microfiber rollers do not shed lint and do not deposit debris in the paint, ensuring a perfectly smooth finish every time.
Woven fabric rollers are also an option for achieving a smooth finish. They produce a notably tight cross-section of fibers and shed minimal fibers, resulting in a virtually lint-free application. Woven roller covers are ideal for applying a high-gloss finish and can be used with multiple paint types such as enamels, eggshell, high-gloss, semi-gloss, satin, flat, and epoxies.
The best roller for the job will depend on the type of paint and the desired finish. For smooth finishes on flat surfaces, choose a roller with a shorter nap. For rough surfaces like concrete block, brick, or masonry, a longer nap is more appropriate.
The two most common sizes for interior paint rollers are 7 inches and 9 inches wide, which are suitable for most home projects.

Mini rollers: less than 5 inches for small surfaces, corners, and hard-to-reach areas
Paint rollers are ideal for large, flat surfaces, such as walls and ceilings, and can help you get the job done faster than using a paintbrush. They are also effective on textured surfaces like stucco, concrete, and brick.
However, for small surfaces and hard-to-reach areas, such as corners, edges, trim, and inside bookcases and cabinets, a mini roller is the best option. Mini rollers are typically less than 5 inches in width and are designed to make paint easy to apply in narrow spaces.
The thickness of the roller cover, also known as the nap or pile, is an important consideration when choosing a mini roller. The nap refers to the thickness of the fibres on the roller cover. For smooth surfaces, such as metal doors, interior doors, trim, and cabinets, a thinner nap of 3/16 to 1/4-inch is recommended. These thinner naps also work well with semi-gloss or gloss coatings and both oil- and water-based enamels.
For semi-rough surfaces, such as wood, stucco, or a textured ceiling, a thicker nap of 3/4 to 1-inch is more suitable. If you're painting rough surfaces like concrete block, brick, or masonry, an even thicker nap of 1 1/4 to 1 1/2-inch is ideal.
When using a mini roller, it's important to note that you may still need a paintbrush for areas that require precision, such as cutting in corners or painting intricate details.
