Roller blinds suit most windows better, and vertical blinds win on sliding doors and wide openings where you want to walk through or angle the light. If the room needs to go properly dark, choose a roller. If people walk through the opening all day, choose a vertical.
Side by side
We make both in our own Sydney factory, so we have no reason to steer you one way or the other. This is how they compare at the window.
| Feature | Roller blind | Vertical blind |
|---|---|---|
| Best suited to | Standard windows and bedrooms | Sliding doors and wide spans |
| How it opens | Rolls up above the glass | Stacks to one side or both |
| Light control | Up or down | Vanes tilt to angle the light |
| Darkening a room | Darker, smaller edge gaps | Some light at edges and overlaps |
| Very wide openings | Usually split into two or more blinds | One track can cover a long span |
| When open | Almost disappears | Stack stays visible at the side |
Doors and walkways
Doors are where a vertical makes the most sense. The vanes stack to the side, so you can open a gap just wide enough to walk through and keep the rest of the door covered. A roller on a sliding door has to go all the way up every time someone wants to step outside.
Rollers do work on doors, and plenty of people prefer how they look there. The catch is that the bottom rail has to clear the handle and the roll has to clear the door head, and on a tall door that is a long drop to raise many times a day.
Our guide to vertical blinds for sliding doors covers the stack side, the handle and the controls in more detail.
Light and privacy during the day
With a standard roller blind the fabric decides how much light comes through, and the blind is either up or down. Double and day night rollers give you more control, but they are a different product altogether.
Vertical vanes tilt. You can angle them away from the street so people walking past cannot see in, while daylight still bounces into the room off the vanes. A roller fabric gives you one fixed balance of light and privacy, where a vertical lets you shift it through the day.
Bedrooms and blockout
For a room that needs to be dark, the roller wins. A blockout roller sits close to the glass and leaves only a thin gap at each side, and in a cassette the light at the top is closed off as well.
Blockout vertical vanes are fully opaque, but light still finds its way in around the edges, along the top of the track and where the vanes overlap. That is fine for a lounge room with a TV and less good for a shift worker trying to sleep through the afternoon.
Very wide windows
Roller blinds are limited by the fabric roll and the tube. Past about 3000mm a single roller starts to sag and the fabric would need a join, so wide windows are usually split into two or three blinds. Our guide to roller blinds for large windows goes through where those splits should go.
Vertical blinds do not hit that limit in the same way. Each vane is its own strip of fabric hanging from the track, so a wider window just means more vanes.
Very long runs are still often made as two blinds that stack to opposite ends. That is mostly so one big stack does not swallow half the view.
Wet areas, dust and wear
PVC vertical vanes are waterproof and wipe clean, which makes them a sensible pick for kitchens, bathrooms and laundries. Many roller fabrics, sunscreens in particular, also handle a wipe down, so both have options for wet rooms.
Dust settles less on vertical vanes than on horizontal slats, but fabric vanes do collect it over time and most are spot cleaned rather than washed. A roller has fewer moving parts. A vertical has carriers, a tilt mechanism and often a bottom chain, which is more to wear on a door that gets used all day for years.
How each one looks
Rolled up, a roller blind almost disappears, especially in a cassette or behind a pelmet. That clean line is a big part of why rollers are so common on standard windows.
Verticals always show their stack, and the upright lines suit tall openings and full height glass. They picked up a dated reputation from old office fit outs, but a soft fabric in a warm neutral on a living room slider looks nothing like the grey office blind most people picture.
Plenty of homes use both. A roller on each window and a vertical on the sliding door, in matching colours, looks planned rather than mixed.
If you are torn, we can bring samples of both and show you how each one would sit on the actual opening. Have a look at the vertical blinds range and our full range of window blinds, then Book a free measure and quote so we can compare the two at your window.
Common questions
Which costs more, a roller blind or a vertical blind?
It depends on the opening more than the type. A wide door might need two or three rollers or a single vertical, and the fabric, the controls and any motor move the figure more than the style of blind. We can quote both at the measure if you are undecided.
Which is better for a bedroom?
A blockout roller blind, in most cases. It sits closer to the glass with smaller gaps at the sides, and a cassette closes off the light at the top. Blockout vertical vanes are opaque but let light in at the edges and where they overlap.
Can I put a roller blind on a sliding door?
Yes. The bottom rail has to clear the handle when the blind is down, and the roll has to clear the door head when it is up. On wide doors the blind is often split in two so each half is easier to raise.
Do vertical blinds let light in when closed?
A little. Closed vanes overlap, but light gets past at the edges, along the top of the track and under the bottom. With a light filtering fabric that hardly matters, but in a bedroom you will notice it.
Can I mix roller and vertical blinds in one room?
Yes, and it is a common setup, usually rollers on the windows and a vertical on the sliding door. Keep the fabric colours the same or close, because the colour matters more than matching the blind type.
