The short version
If your window is wide, tall or a patio door, vertical blinds are usually the easier fit. If your window is a standard size and you want a flat, tidy look, roller blinds are usually a lovely choice. Plenty of windows could take either, so the rest of this page is about the details that tip the decision.
How each one works
Roller blinds are a single piece of fabric that winds around a tube at the top of the window. You pull the fabric down to cover the glass and roll it up to clear it. Depending on the range, they can be operated by a chain, a spring mechanism or a motor.
Vertical blinds are a row of hanging slats (called louvres) on a track. The slats rotate to let light in or keep it out, and the whole row draws to one side or splits to both sides. Control is usually by a wand or cord, with motorised options depending on the range.
Where vertical blinds make more sense
- Patio and French doors. You can draw the slats clear of the door without lifting anything out of the way. See our patio door guide for more on this.
- Very wide windows. A wide single roller fabric can look heavy and can be awkward to operate. A track of slats shares the width.
- Rooms where you want fine control of light. Turning the slats lets you angle daylight away from a screen or sofa without closing the room off.
- Large conservatory-style openings. Tall glazing is where vertical slats tend to cope best, though check our conservatory advice as roofs are a different matter.
Where roller blinds make more sense
- Kitchens and bathrooms. A flat fabric has fewer gaps to catch splashes and is quick to wipe, depending on the fabric. Our bathroom guide covers materials.
- Small and standard windows. A roller sits neatly in a recess and rolls up into a compact tube.
- A clean, modern look. One uninterrupted surface suits minimal rooms and bold fabrics.
- Bedrooms and nurseries. Some roller fabrics are made specifically to cut light, and you can ask about blackout options and side channels.
Things worth weighing up
Light gaps. Vertical slats overlap when closed, but there can be a thin line of light between them and at the edges. Rollers can show light round the sides unless they are cut to suit the recess or fitted with side channels.
Noise and movement. Vertical slats can swing or knock if a window is opened wide on a breezy day. A roller stays put, though a chain can tap the wall if it is not fixed.
Stack space. Verticals bunch up at one side or both when open, and that stack sits in front of part of the glass. A roller rolls up at the top, so it takes a little height instead. If you want the full view, think about which matters more to you.
Damage and repair. A single bent or cracked slat on a vertical blind can often be replaced without replacing the whole blind, which is handy in busy houses and rentals. A damaged roller fabric usually means a new blind. Ask us what applies to the range you choose.
Cords and chains. Both can have loops or cords that need to be kept out of children's reach. If young children use the room, our child safety questions are a helpful read before you decide.
A quick decision test
- Is the opening a door, or wider than it is tall? Lean vertical.
- Do you want the glass fully clear at times, with the fabric tucked out of sight? Lean roller.
- Is there a radiator, sill or handle in the way? Roller in a recess may need a closer look, and a vertical hung from the ceiling or wall may clear it better.
- Do you want to adjust the angle of light through the day? Lean vertical.
- Do you want a single plain surface to match a modern scheme? Lean roller.
If it is still a toss-up
Window depth, handles, radiators and the way a door swings can all change the answer, and they are hard to judge from a photo. We can look at the actual opening and talk you through what will work.
