Paint roller covers come in a variety of nap sizes, each designed for specific surfaces and paint types. The nap size, or thickness of the fibres, determines how much paint the roller can hold and how textured the finish will be. For smooth surfaces, a shorter nap is ideal, whereas a longer nap is better for rough surfaces. The right nap size ensures even paint distribution and a smooth finish. Different nap materials, such as microfiber, nylon/polyester, and natural fibres, are also suited for specific paint types and surfaces.

What You'll Learn
Nap size depends on the surface being painted
The nap size of a paint roller is the length of its fibres. The right nap size helps apply paint evenly, ensuring optimal coverage and a smooth finish.
For smooth surfaces, such as new drywall, doors, metal, or sanded wood, use a roller with a short nap. A 3/16" to 1/4" nap is ideal for these surfaces. These rollers are designed to hold a small amount of paint, which helps achieve an ultra-smooth finish. They work well with glossy or semi-gloss paints.
For interior walls and ceilings, a 3/8" to 1/2" nap is suitable. This size is versatile and works well with flat, satin, and low-sheen paints on lightly textured surfaces like walls, ceilings, and panelling.
For rough surfaces like textured walls, stucco, concrete, brick, or concrete blocks, use a longer nap of 3/4" to 1 1/4". These naps hold more paint and can get into deeper textures, providing better coverage on rougher surfaces.
The length of the roller also matters, depending on the area to be painted. A smaller roller is better for tight spots, while a larger roller is more suitable for wide-open spaces like walls or ceilings.

Nap size depends on the paint being used
For semi-gloss or high-gloss latex paint, a foam roller cover with a short nap is recommended for smooth surfaces. If you are using water-based paint, nylon/polyester rollers are a good choice as they resist matting and produce a smooth surface. For oil- or alkyd-based paint, natural fiber rollers made from lamb's wool or mohair are suitable for any surface.
The thicker the nap, the more paint a roller can hold. This is ideal for rough surfaces that absorb a lot of paint. A thicker nap is also better for textured surfaces as the long fibers can reach into the cracks and crevices, providing better coverage. For example, a 3/4" to 1 1/2" nap is recommended for very rough surfaces like brick and concrete blocks to ensure effective paint coverage.
It is important to consider the desired finish when choosing a nap size. A shorter nap will provide a smoother finish on smooth surfaces, while a longer nap may leave a textured look. Additionally, the material of the nap is important to consider, as different materials hold varying amounts of paint. For example, knit fabrics like polyester and lambswool hold more paint and cover larger areas faster, but may leave a stipple effect.

Nap size affects the speed of the job
The nap size of a paint roller cover can significantly impact the speed at which a painting job can be completed. The nap size refers to the length of the fibres on the roller cover, which affects paint pickup and release capabilities.
Shorter naps, typically ranging from 3/16" to 1/4", are ideal for smooth surfaces like drywall, plaster, metal, or cabinets. These naps hold less paint, resulting in a smoother finish. While shorter naps may require more time to complete a project due to their reduced paint capacity, they are often preferred for achieving an ultra-smooth appearance on delicate surfaces.
On the other hand, longer naps ranging from 3/4" to 1 1/2" are designed for rough and textured surfaces like brick, concrete, stucco, or heavily textured exteriors. The longer fibres can reach into the cracks and crevices of these surfaces, providing excellent paint pickup and release. Longer naps can cover a larger area with paint in a shorter amount of time, making them a faster option for rough surfaces.
It is worth noting that while longer naps can speed up the painting process on rough surfaces, they may leave a slightly more textured finish on smooth surfaces. Therefore, it is crucial to consider the desired outcome and select the appropriate nap size accordingly.
Additionally, the material of the roller cover also plays a role in the speed of the job. Knit fabrics like polyester and lambswood hold more paint and can cover larger areas faster, while microfiber can hold up to three times more paint than a standard roller cover.
The size of the roller also impacts speed. Larger rollers can cover more surface area with each roll, making them faster for wide-open spaces like walls or ceilings. Conversely, smaller rollers are more suitable for tight spots and narrow areas.

Nap size impacts the finish
The nap size of a paint roller cover is the length of its fibres. Different nap sizes are suitable for different surfaces and paint types.
For smooth surfaces, such as new drywall, doors, metal, or sanded wood, a shorter nap size is ideal. A 3/16" to 1/4" nap will help you achieve an ultra-smooth finish. These rollers are designed to hold a small amount of paint. They work well with glossy or semi-gloss paints, giving you a flawless look.
If you're working on lightly textured surfaces like interior walls, ceilings, or panelling, a slightly larger nap size of 3/8" to 1/2" is recommended. These naps are versatile and suitable for flat, satin, and low-sheen paints.
For rough surfaces like textured walls, stucco, concrete, or brick, longer naps ranging from 3/4" to 1 1/2" are recommended. These naps can hold more paint and are better at getting into deeper textures.
While longer naps can speed up your painting process by holding more paint, they may leave a slightly more textured finish on smooth surfaces. Therefore, it's important to select the appropriate nap height that aligns with your desired finish.
Additionally, consider the fabric of the roller cover. Knit fabrics like polyester and lambswood hold more paint and cover larger areas faster, but they may leave some stipple. Microfibre covers hold a lot of paint and provide a smooth finish, but there is a risk of drips. Natural fibres, such as lamb's wool or mohair, work on any surface and are suitable for oil- or alkyd-based paint.

Nap size and material are both important considerations
The material of the roller cover also matters. Knit fabrics, like polyester and lambswool, hold more paint and cover larger areas faster but may leave some stippling. Microfiber roller covers hold a lot of paint and provide a smooth finish, working with all paints and sheens. Nylon/polyester roller covers are suitable for water-based paint and produce a smooth surface. Natural fibre roller covers, made from lamb's wool or mohair, work on any surface and are suitable for oil- or alkyd-based paint.
When choosing a paint roller cover, it is important to consider the surface you are painting, the type of paint you are using, and the desired finish. For example, if you are painting a smooth surface, a shorter nap is better to achieve a smooth finish. If you are painting a rough surface, a longer nap is needed to reach into the cracks and crevices of the surface. Additionally, some roller covers may be better suited for certain types of paint.
The size of the roller is also a factor to consider. Smaller rollers are better for tight spots and edges, while larger rollers are more suitable for wide-open spaces, like walls or ceilings. The length of the roller will also determine how much surface area you can paint.
