Easy operation, low maintenance.

One of the attractions for blockout blinds, as a popular window coverings choice, is that they are low maintenance and super easy to operate.

What's the wait? 

Once we have all the necessary details and the green light from you; your blockout blinds usually take 3–4 weeks to manufacture (the 'no frills' range is 10-15 working days). Plus 1–4 days freight depending on where you are in NZ, and whether we’re installing, or you are. Well made blockout blinds; ones that will last years to come, have not been rushed in manufacture. See the ‘key questions to ask’ section above to make sure you’re ordering lasting quality.

Literally hundreds of colours and styles.

When it comes to blockout blinds, the fabrics to choose from here are in the hundreds. All the fabrics we offer, without exception, come from reputable New Zealand based fabric suppliers with well proven track records in supplying lasting quality. Beware of rip-off, often Chinese sourced, fabrics that aren’t designed for our NZ UV conditions and just don’t last. With fabrics that range from plain to textured to designer, with thermal backing or not, blockout blinds can blend in or make a statement. Fabric choices can also be made with your budget in mind; from the cost conscious to those that want to create an in-home experience. Don’t be overwhelmed; use the fabric selector to filter by fabric name, hue, design, price, lead time or backing type or a mix of any of these criteria. And you’re always welcome to ask me for guidance toward choices based on your needs.


Measuring step by step.

By following the steps below with calm collected focus you’ll measure correctly every time. Transforming some people from that state of measuring anxiety to one of higher level tape-measure boss. Guaranteeing blockout blinds that have been measured perfectly every time. Whether you need ‘inside the reveal’ instructions or ‘outside the reveal’ instructions, these are available as pdf’s below. The most common approach, 'inside the reveal', is described next…

Measure in 3 steps

1. Width 3 times.

With your trusty tape measure in hand, measure the width of the reveal in which your blockout blind will be going. Best practice is to measure the width at three different heights and take the lowest measurement. This makes you read the tape measure 3 times and allows for any indiscrepancies in your window frames. Measure the width near the top, in the middle, and near the bottom. This takes the ‘measure twice, cut once’ to a whole new level. Be sure to hold the measuring tape level and measure from inside edge to inside edge (wood to wood) of the window reveal. To make it easier, especially on the wider windows and doors, bribe a family member to help with promises to make their favourite meal. It’s the smallest width measurement in millimetres you’ll need.

2. Measure the drop.

When it comes to measuring the drop of the blockout blind we aren’t nearly so fussy. The blockout blind is always made with extra fabric in the roll. That being said, it’s never time to get complacent – hold that measuring tape perpendicular to the sill, read the tape correctly, and transpose those crucial millimetres with accuracy. No one likes crying over mis-measured blockout blinds.

3. Supply measurements.

Hit ‘Get A Quote’ and enter your blockout blind measurements as width X drop in millimetres (mm). If you are getting us to check measure at some point or you’re DIY and want a quick price initially just enter approximate dimensions for now. Exact measurements will be required before proceeding with any orders.

Easy install.

With the following instructions you’ll have your blockout blinds installed, easily, in no time. Three easy steps ensure they are installed like the pros. For the most part blockout blinds are installed inside the window reveal, which the following instructions outline. For installing blockout blinds outside the reveal, and other more specific install variations, these are all below as downloadable PDF’s. Let’s get your blockout blinds installed…

1. Preparation.

The usual suspects for any great blockout blind installation are appropriate screws, the corresponding screwdriver or if you’re super handy, a power drill, again with the correct bit to drive those screws in. You might also need a 2mm drill bit, pencil and tape measure for next level accuracy, and a step ladder for getting up in the zone at some windows.

Now, limber up and unpack your fresh new blockout blinds.

2. Fit the brackets.

So you’ve limbered up and are feeling positive; time to place and fit the all-important blockout blind brackets. Each blind has two brackets – one male bracket for the chain control side of the blind, and one female bracket for the pin end (or non-control end). Hold the brackets in place, in your window frame, where they are to be fixed. Think about the desired depth of the blockout blind within the reveal, the fall of the blind fabric, and position the brackets so the blind will miss any handles or latches, etc.

With a pencil, mark where the two screws will go; I generally go up through the top of the bracket (2 screws per bracket is ample). You could drill a pilot hole in the middle of each mark, with a 2mm drill bit; especially if your super close to an edge where wood can split more easily sometimes. If you’re screwing into solid wood and the thread on your screws isn’t too coarse you’ll be fine without drilling pilot holes. Use the screws provided to fix the brackets securely in the window frame.

TIP 1: Perhaps just hold the first blockout blind up in the window to help gauge at what depth the blind will work best; missing obstacles and looking the business.

3. Fit the blockout blind.

Remove the blockout blind from its packaging leaving the securing band around its middle. Or take a sneak peek at TIPS 2 & 3 below as potential precautions. Slot your blockout blind into the male bracket (chain side) first, ensuring the control chain hangs freely and that the ends of the guarded part, that partly encloses the control chain, are on the top and level front to back. Hold the chain-side in position and move to the other side of the blockout blind. Retract the metal spring-loaded pin slightly by turning the grooved plastic wheel part – then guide the pin up into the groove of the female bracket until it clicks safely into position. Carefully remove the securing band from around the blockout blind and well done you’re free to lower and raise your blockout blind to your hearts content.

TIP 2: Keep your blockout blinds safely inside their wrappers, safe from any lurking chocolate biscuit fingers, until the exact moment of installation.

TIP 3: If your blockout blinds are white or light coloured you may want to keep them in their plastic packaging, and just cut the ends so the blind ends are free to be installed, and then carefully rip or cut the wrapper off completely. This way avoids even the oil on sweaty fingers and palms from ruining your day (or wear surgical gloves as an extra precaution).

When I was researching and enquiring about blockout blinds Ryan was extremely helpful and proactive. Ryan was an excellent communicator, very quick in providing a quote and responding to questions. He provided good advice and sent through several samples for me to choose from. The blockout blind quality was excellent and very easy to self install. I would recommend Ryan and Blinds Online.

What is the widest blockout blind possible?


Generally speaking the maximum blockout blind possible is 3m wide. That said, there are considerations to be aware of when selecting blockout blinds at 3m wide or even close to that – please see the FAQ entitled, 'Are there any potential concerns to be aware of with wider blockout blinds?'

Most blockout blind fabrics come from the fabric supplier at 3 metres wide. (Not all, but most. To check a particular fabric range's maximum width please check the info pop-up on the 'fabric range' name. You'll find this information on the 'fabric selector' pages). We can't use all of the 3m width as we need some 'play' to ensure we can lay and cut your blockout blind edges straight. But if you want a blockout blind to fit 'inside the reveal' 3m wide, we can do it, as the fabric needed for this width blind is actually 3m minus 32mm (we take 15mm off one side and 17mm off the other side – see the FAQ entitled, 'How wide are the light gaps on the sides of your blockout blinds?').

There is more info here than is needed by most however I have found it helps some people in some situations understand what can be done. For the most part please check maximum fabric widths and this will be the maximum 'inside fit' blockout blind we can do for you, in that fabric. That said, please take into account the main considerations I have pointed to before deciding whether a blockout blind this wide is right for you. ie: see the FAQ entitled, 'Are there any potential concerns to be aware of with wider blockout blinds?'

NB: Some companies will 'railroad' fabrics to obtain wider blockout blinds. Railroading is where the fabric is spun 90º so wider widths can be obtained. It is my recommendation and that of any reputable manufacturer that blockout blind fabrics should NOT be railroaded. You will experience performance issues.


As blockout blinds get wider there will be some deflection or slight sag in the head tube (that spans between brackets) and from which the blockout blind fabric hangs. This deflection is caused by gravity over these wider spans. The deflection can then cause slight 'vee-ing' or 'sagging' in the fabric which presents itself as a wrinkle or V shape, usually down the centre of the fabric. It's often very subtle; some people notice it, many don't. Different fabrics or colours make this more noticeable or not. Ceiling down-lights nearby really highlight any 'vee-ing', if present. Lighter coloured fabrics tend to show 'veeing' more than darker colours in my experience. This effect can be more pronounced with 'softer' fabrics. The bigger the blockout blinds are the more obvious this effect can be. 'Vee-ing' applies to all roller blind types, not just blockout blinds. Our manufacturing specifications introduce a heavier duty, reinforced head tube for blockout blinds over 2m, to minimise this effect. When I say 'wider' I start to advise clients about the possibility of 'vee-ing' around the 2.5m wide mark and it's usually more common when it's those greater widths coupled with a full drop (1.8m and greater). As you can see there is no exact science to this phenomenon; if you feel it is going to be an aesthetic issue for you I'd suggest splitting 'wider' window/door spaces into two blockout blinds where possible or practical. 'Vee-ing' is a characteristic of wider blockout blinds and is not considered a manufacturing fault or fabric flaw. It is impossible to hang pieces of fabric this large completely flat.


Here's a potential trap for new comers to the blind world. When considering 'back rolled' blockout blinds please consider what colour the back of your considered fabric will be. Most blockout blind fabrics are thermally backed and most of these have a white backing. You will see this white backing along the top of a 'back rolled' blockout blind. If the fabric front you choose is white it will all blend together, so no problem. If the fabric you choose is darker than white, you'll have a contrast and a surprise for those not expecting it. I don't dislike this contrast myself, I think it looks quite good, and as most people's architraves are white it tends to work well. You'll need to decide what works for you though. Most non-thermally backed blockout blind fabrics are the same colour both sides. Some thermally backed blockout blind fabrics have a matching tone backing. 'Back rolled' blockout blinds are most common if you are 'outside mounting' the blinds for some reason, or you are 'inside mounting' but the window reveal is very shallow and to have the fabric hang within the reveal, you need to 'back roll'. The lists below will assist you in choosing a fabric appropriate to your needs (should any of this be of concern to you).

Tall narrow blockout blinds can be very problematic and at times 'track' to the left or right. They track (which means they don't roll up exactly true or square) because there isn't enough width in the blockout blind to have the fabric really 'sit' and play nicely, always. The fabric may track to the side and jam in the control mechanism, causing damage to the fabric. When I say tall and narrow I mean in the vicinity of under 600mm wide with a full drop of around 2000-2400mm. This phenomenon isn't an exact science; it doesn't always happen, however I err on the side of caution as it has happened enough times to cause issues for everyone involved. Different fabrics, at different parts of a large suppliers roll can behave differently at different times. Plus the speed, roughness, or fluidity of the operator (you) can impact whether any size blockout blind tracks or not. Please note, these potential issues apply to all roller blind types, not just blockout blind fabrics.

So, what are the options? I encourage people to do timber venetians for tall narrow windows instead of blockout blinds. Shutters can look really smart as well in tall narrow spaces. Or we'll make them for you if you insist however you're on your own. Any blockout blinds under 600mm wide do not come with a warranty. With care they may behave. Sometimes a little guidance from you when they deviate off track can help to 'train' the fabric to roll true, ie: holding the fabric edge or bottom-rail and keeping the fabric square (by looking at the edge of the rolled up fabric at the top) as you roll the blockout blind up.


If 'inside fitting' standard blockout blinds there will be a light gap on both sides. These gaps are required as there is componentry and brackets which sit outside the outside edge of the blockout blind fabric. The gaps measure approximately 17mm on the control chain side of the blind and 15mm on the idle end (opposite side) of the blockout blind. Our gaps are some of the narrowest in the industry.


Not really however I'll expand on that so you can make the right decision for you. Generally louvre windows are there as a good way to allow air to enter and exit a room; to provide airflow. If your blockout blind (or any other roller type blind) is down, while the louvres are open, it will blow and suck into the louvres and may cause damage or stretching to the fabric over time. Your warranty won't cover damage caused by using blockout blinds in conjunction with louvre windows in this way. Another factor that often comes into play with louvre windows is that the blind covering it may well fall into the 'tall narrow' blockout blinds category, which in itself is problematic. Please see the FAQ entitled: 'Are tall narrow blockout blinds a good idea?'

Sometimes the louvres windows are a small section of a much larger window space. You could stop the blockout blind short of the louvres or have it covering the whole width. If you choose to cover the whole width then when you use the blockout blinds or not and when you use the louvre windows or not needs to be thought through carefully with all this info in mind. If louvre windows are open it's best to have blockout blinds safely up and out of the way.


Blockout blinds are made square; the fabric is cut on an expensive cutting table and blinds are all hung in a jig and tested before leaving the factory. It's next to impossible to have a bottom rail that has been put on crooked. It has always been my experience when this comment is made that the window frame isn't square. Either it's a villa where the house has moved significantly or the window frame is out of square to some degree. The top of the window isn't level, or the sides aren't vertical, or there is bowing or a high point on the window sill where the bottom rail hits first making it not sit level.

I take all potential issues seriously – please send me a photo of the blind in the window frame for me to comment on. I do recommend checking window level and squareness initially though; if we come out to site or the blinds are returned to factory, by you, and it is found that the building or the window frame is the issue, and not the blockout blind, there will be a charge to cover time and expenses.

TIP: If it's an 'outside fit' blockout blind and you've used the top of the architrave as a guide, assuming it is level; often they aren't level. This is an easy trap for beginners to fall into.


Yes, we have had images or logos printed on blockout blinds before. We can print on blockout blinds, sheer/light-filtering fabrics, and sunscreen fabrics. Pretty much all fabrics we supply can be printed on however plain fabrics do produce better results (ONEBLOCK, KEW and ICON for example). Depending on the size of the blockout blind and the size of the image going on it (and whether one or more blockout blinds need to be aligned with each other) depends on how much extra fabric may or may not be needed to do this successfully. The printing machine needs to hold the fabric at two ends, so more fabric may be needed initially to print, before the blockout blind is then sized and cut to your window size requirements. Also depending on what is to be printed we need to pick your fabric base colour accordingly.

To do an initial quote please supply: the blockout blind size (width X drop in mm's). Or if an image is going across two or more blockout blinds, then the individual blind sizes and an indication that the image is to go across multiple blinds. Be aware that if the image is going across two blinds, there is a gap between the two adjacent blockout blinds. Also a decent resolution JPEG of the image to be printed and the image size you had envisioned on the blockout blind. (before printing the printers may request a better resolution file however we will advise you if this is necessary). Please also supply an idea of the base fabric colour you had planned, for your blockout blind.


Don't panic; this is a relatively easy fix. All is not lost. If you've already installed the blockout blind; take it back down. Carefully wiggle the ‘control end’ mechanism out of the blockout blind head tube. Wiggle the ‘idle end’ component out of the blockout blind head tube as well (this is at the opposite end to the control end mechanism). Swap these over and firmly reinstate. Voilà, your left hand control blockout blind is now a right hand control blockout blind (or vice versa). NB: Before you go showing off this neat new trick, make sure you've swapped the brackets over too (if already installed), side for side, before reinstalling the blockout blind. There you go; said it was an easy fix.

Argh perhaps too easy in some cases. Here's the twist...if the blockout blind is quite large there may be a 'spring assist' mechanism attached to the 'control end' mechanism inside the head tube. You'll discover whether there is a 'spring assist' or not when you wiggle out the control end. 'Spring assist's' are either LH or RH and can't be used on the opposite side of the blockout blind. From here you have 3 options. 1: live with the control chain on the wrong side, as ordered. 2: remove the spring assist altogether (there's a small screw attaching it to the control end mechanism). While the 'spring assist' does assist the operation of larger blockout blinds, it isn't completely necessary in my experience (when saving the day on-site under these circumstances in the past). Or option 3: purchase the correct side 'spring assist' from us and reassemble your blockout blind when you've received it (approx $62+gst). You may even trial option 2 before committing to option 3, and see how you go. There is an option 4 as well actually: send the blockout blind back to us to do however this gets tricky freight and cost wise for you and with the above description I know you can successfully pull this surgical procedure off perfectly.


You're right. The vast majority of blockout blind fabrics (with thermal backing) have a white backing. If for whatever reason you don't want or like the white backing, don't panic. There are ranges that are the same colour front and back (non-thermal backed fabrics). And there are some thermal backed blockout blind fabrics that have a 'tonal match' backing. Available blockout blind fabric ranges are listed below with their backing type. You can also view fabric ranges online using our blockout blind 'fabric selector': (Just 'reset filters' and choose from the 'fabric name' dropdown).

If you're likely to proceed and get blockout blinds from us, I'm happy to send your chosen fabric ranges out so you can see the fabrics in person. So you feel confident picking the colours and backing right for you.

All our blockout blind fabrics are completely 'blockout', in that no light passes through the fabric itself. All the fabrics we provide are from reputable NZ based fabric suppliers and are fabrics proven to last in our harsher UV conditions. It is important to note that you do have light gaps down the sides of blockout blinds when mounted inside your window frames. See the FAQ entitled: 'How wide are the light gaps on the sides of your blockout blinds?' for more info on that aspect.

The more 'simple' blockout blind fabrics are Oneblock, Vibe and Focus, which are all priced the same currently and are some of the most affordable. If by 'simple' you mean the lowest cost blockout blind possible, we would use Dawn. Dawn is just as good as the above mentioned fabrics however I have these blockout blinds made in a different factory altogether for the most cost conscious buyers I deal with. Going this route you forgo Acmeda which is the best componentry in my experience (all the important bits that make up blockout blinds other than fabric: head tube, control end mechanism, control chain, idle end, etc). I say this after extensive experience repairing all brands of blockout blinds across the market. If by 'simple' you mean cheap, we don't do cheap as these cost more in the long run (again from my experience coming in after people learn the expensive way).
