When I go to get supplies for a job, I always see people standing in the paint roller cover aisle having no idea what they need. I get it, when I first started painting I thought they were all about the same. I figured I could get one that was medium priced and it would do all I needed. I was wrong.
There are dozens of options. Different nap lengths. Different fabrics. Different price points. And every package claims to be the best choice.
The good news is that choosing the right roller cover is actually much simpler than it looks.
In almost every situation, it comes down to answering one question:
What surface are you painting?
The texture of the surface determines the nap thickness you need, and once you understand that, choosing the right roller becomes easy.
Below I’ll walk through the most common surfaces homeowners paint and the exact roller covers I recommend for each.

Interior Walls (Most Homes)
Nap: 3/8 inch
Material: Microfiber
My Personal Choice: Purdy 9-in x 3/8-in Nap Microfiber Roller Cover
This is the workhorse roller for interior painting and the one I use most often.
A 3/8″ nap holds enough paint for solid coverage while still leaving a smooth finish on drywall.
This roller works great for:
- Living rooms
- Bedrooms
- Hallways
- Offices
- Most painted drywall
If you’re only buying one roller cover for a project, this is usually the one to grab. I bring a 3 pack to every job to ensure we are ready for two coats and a possible primer coat.
Ceilings
Nap: 3/8″ or 1/2″
Ceilings benefit from slightly thicker nap because it holds more paint and prevents dry rolling.
Dry rolling is one of the biggest causes of visible lap marks on ceilings.
A thicker nap helps maintain a wet edge and keeps the finish looking even.
Pro tip: Always use an extension pole when painting ceilings. It allows more even pressure and smoother roller passes. If you’re painting an entire room, you may also want to read my guide on what order to paint a room.
Lightly Textured Walls
Nap: 1/2 inch
Many homes have light wall texture like orange peel drywall.
A 3/8″ roller can still work, but a 1/2″ nap often performs better because it reaches into the texture more easily.
This type of roller works well for:
- Orange peel drywall
- Light plaster texture
- Slightly uneven walls
Heavy Texture (Stucco, Brick, Masonry)
Nap: 3/4 inch or thicker
Heavy textures require longer nap so paint can reach into deeper surfaces.
Short nap rollers will skip over the texture and leave unpainted pockets.
This type of roller works best for:
- Stucco
- Brick
- Concrete block
- Exterior masonry
Cabinets, Doors, and Furniture
Material: Foam rollers
Foam rollers create extremely smooth finishes on very flat surfaces.
They are commonly used for:
- Cabinet doors
- Metal doors
- Furniture
- Smooth trim
Foam rollers hold very little paint, which is why they are not used for painting full walls.
Why Roller Quality Matters
Roller covers may look similar in the store, but cheap ones cause three common problems:
- Lint stuck in the paint
- Uneven roller texture
- Streaky paint coverage
Better rollers hold more paint and release it more evenly.
That means:
- Fewer reloads
- Faster painting
- Smoother finishes
A good roller cover usually costs between $5 and $10, which is a tiny cost compared to the paint and time involved in the project.
How to Prep a Roller Cover Before Painting
Before using a brand new roller cover:
- Rinse it lightly with water
- Spin or shake out excess water
- Roll it across a dry paint tray
This removes loose fibers that could end up stuck in your paint.
Another trick painters use is wrapping painter’s tape around the roller and pulling it off to remove debris.
If you rinse with water, make sure the roller is almost dry before loading paint.
How to Avoid Roller Marks
Roller marks (also called lap marks) usually happen because of:
- Using the wrong nap thickness
- Letting paint dry between passes
- Pressing too hard
- Using cheap roller covers
The best approach is to maintain a wet edge and roll with light, even pressure.

FAQ
What nap roller should I use for interior walls?
Most drywall walls paint best with a 3/8 inch nap roller cover.
Are expensive roller covers worth it?
Yes. Higher-quality roller covers hold more paint, release it more evenly, and produce smoother finishes. Even a high quality roller costs as much as a latte at your favorite coffee shop, so there is no reason to skimp here. When you are looking at a roller in a store, you will often see, ” Good, Better, Best”. Always get best, its worth the extra few bucks. Look at the recommended DIY Painting Products list here.
Should you reuse roller covers?
You can reuse them if cleaned thoroughly, but many painters prefer using a fresh roller for the final coat.
Why does my roller leave fuzz on the wall?
This usually happens when using cheap roller covers or failing to prep a new roller before painting.
Do different paints require different rollers?
Sometimes. Thick primers or masonry paints may benefit from slightly longer nap rollers. If you still have questions, be sure to check out my Guide To Your First Home Paint Project.
