What Paint Roller Do I Need? - The Ultimate Guide

What Paint Roller Do I Need? - The Ultimate Guide

When it comes to painting, a lot of attention goes to picking the perfect paint colour (I get it, it’s exciting!), but how often do we think about the tool that’s going to apply it? Yup, I’m talking about the humble paint roller. It might not seem as glamorous as choosing paint, but picking the right roller can make or break your project. A good roller will give you a smooth, even finish, while the wrong one can leave you battling streaks, roller marks, or even worse - shed lint onto your freshly painted wall! Nobody wants that.

So, let’s break down the must-knows for choosing the right roller, and I’ll even compare a few of my top picks from the shop to help you make the best choice for your project.

Roller Must-Knows

Before we get into specific recommendations, here are a few basics to help you understand what kind of roller you’ll need.

1. Nap Length (Pile)

The nap, or pile, of a roller is essentially the length of its fibres. Different nap lengths are suited to different surfaces:

  • Short Pile (5-8mm): Perfect for smooth surfaces like plastered walls or ceilings. If you want a sleek, even finish with no texture, go for a short-pile roller.
  • Medium Pile (10-12mm): Ideal for slightly textured surfaces, like lightly artexed ceilings or textured wallpaper. It holds more paint, so it’s great for coverage but doesn’t leave too much texture.
  • Long Pile (15-20mm+): For rough surfaces like brick, stucco, or textured ceilings. These rollers hold loads of paint and get into the nooks and crannies of uneven surfaces.

2. Roller Material

Not all rollers are created equal—different materials work better with different types of paint and surfaces.

  • Foam – Great for Woodwork
    Perfect for small, flat surfaces like doors or trim, foam rollers give a smooth finish with water-based gloss or satin paints.
  • Mohair – Ideal for Woodwork
    Use mohair rollers with oil-based paints for a streak-free, professional finish on woodwork like cabinets and doors.
  • Fluffy Rollers – Made for Walls
    Best for large, textured surfaces like walls and ceilings. They hold lots of paint and cover uneven areas well.
  • Microfibre – Versatile for Everything
    The all-rounder! Microfibre rollers work on walls, ceilings, and woodwork with both water-based and oil-based paints.
  • Velour – Perfect for Woodwork
    Another option for a smooth finish on wood, especially with oil-based gloss or satin.

3. Size

Rollers come in different widths, but don’t let that intimidate you. The size you choose depends on the space you’re painting:

  • 4-inch (Mini Rollers): These are great for tight spaces, trim, doors, and cabinets. You’ll have better control and fewer mistakes.
  • 9-inch Rollers: The standard size for walls and ceilings. If you’re painting a room, this is your go-to.
  • 12-18 inch Rollers: These are for covering large surfaces quickly - ideal for big walls, ceilings, or even exterior walls.
