Sometimes you just need some peace of mind when you come to place an order for your blinds. With DotcomBlind’s Right-Size Guarantee you can have just that. With our Right-Size Guarantee we will replace a blind with the correct size if you get the measurements wrong when you order. Please note, the Right Size Guarantee excludes Cassette Blinds.
Why do I need this Insurance?
We can’t accept returns or provide refunds for blinds that are mismeasured because all of our blinds are made to measure and so the onus is on the customer to get the measurements right for their blinds. Sometimes you might just be having an off-day, get your centimetres and inches mixed up and end up with a blind that is nigh-on useless. With our Right-Size Guarantee we will take that blind back, remake it to the correct size for you and send it back, saving you from having to buy a totally new blind! The Right Size Guarantee covers all made-to-measure blinds and curtains except our Cassette Blinds.
How does it work?
✔ Purchase Right-Size Guarantee when you place your order
✔ If one of your blinds has been measured incorrectly, get in touch with us within 14 days and we’ll tell you how to return the blind to us.
✔ Once your blind is with us, we’ll remake it or adjust the blind to your correct measurements and send it back.
✔ Please read our terms and conditions for full details as you will incur additional costs returning the blind to us.

How to Measure
Now, you can’t mess this one up. It’s what we call ‘easy’ here at DotcomBlinds. But just in case you need some help, follow this quick guide.
First thing's first, identify whether your blind is going inside or outside of a recess.
Inside the recess
A recess fit blind means you supply us with the width and drop of your recess – from top to bottom and wall to wall. We make deductions to account for the brackets to ensure your blind fits within the recess perfectly.
To measure a roller blind to fit inside the recess of your standard window, simply measure the full width and the height of the recess. Then input those measurements into the product page with your order selecting the ‘recess’ option. We’ll do the rest, leaving you the well-deserved excuse to put your feet up, you worked hard for it after all!
Don’t be tempted to deduct any measurements, we do this for you. Make sure you use a metal tape measure; a cloth one can stretch and give you more millimetres per centimetre than a pound-shop ruler. Also, take your measurements in three places and give us the smallest (if there is a smallest). You will find that some recesses shift and settle over time.
Outside the recess
A blind going outside of a recess is usually called an exact fit blind. An exact fit blind means we won’t make any deductions to the width or drop measurements. Exact fit is the bracket to bracket measurement and is commonly found installed outside of a recess. The size you give us is the size your blind is made to.
If you want your blind to hang outside the recess, measure the height and width but be sure to add some overlap to reduce light leakage. This overlap should be about 70mm at the top and bottom and 50mm each side, ensuring you suffer no dazzling strips of sunlight once your blind is happily installed. Please select the ‘exact’ size option when ordering.
Choosing the best control option for you
We provide three control options with our roller blinds, meaning you can choose the right means of operating your blind to suit your needs, location of the window and the room you choose to install it in.
A chain operated roller blind has a safe breakaway chain that is designed to come apart under excessive weight, providing a huge amount of safety. Due it the chain being made from metal, it has a substantially longer lifespan compared to the plastic alternatives. A chain operated blind boasts a smooth, quality action and an air-cooled design that make it a joy to operate.
A crank operated roller blind removes the need for cords and chains thanks to our innovative solution: a crank and handle. By turning the crank handle, the blind is raised or lowered, and on many models, the crank handle can be removed entirely. Easy to use and incredibly child safe, a crank operated roller blind is an easy-to-use way to open and close a blind.
Ensuring our products are child safe is a priority for all of us at DotcomBlinds. As a result, our blinds are child safe by design, with built-in safety mechanisms to help reduce the risk of an accident. These mechanisms specific to roller blinds are:
• All chains provided with our products are made at a maximum length of one metre
• Chain tensioners (or p-clips as they're also known) are supplied with every chain operated blind to hold the chain out of the way of children
We offer Child Safe Plus features with our roller blinds, which are an upgrade to remove the chain mechanism and replace it with a cordless means of operating the blind.
Our crank operated roller blind option replaces the chain with a detachable crank handle which hooks onto the mechanism and is turned, lowering or raising the blind as it goes. The crank handle can be unhooked and put out of reach of children and ultimately removes any chance of loops which are the biggest risk-potential when it comes to blinds.
We also offer an electric blind option which means the roller blind is controlled by remote control. Again, this removes any chains or cords and also makes operating a blind more convenient.
If you have any questions around child safety and our blinds, please do not hesitate to get in touch, we're always happy to help.
How to Install
You overcame the measurement minefield and now you must face the final challenge – installing your roller blind. Honestly, it isn’t half as bad as you think it is, and with this very easy guide, you’ll be done in no time. Grab a cuppa and have a quick read through our instructions to familiarise yourself before you get started. The tools you’ll need are: drill with 5mm drill bit, tape measure, suitable fixing plugs, screws and a screwdriver.
Before you begin match the brackets up to the blind. You’ll notice one end has a circle and the other has a cross shaped opening. The control end goes into the cross shaped bracket and the pin-end goes into the circle. Doing this will ensure you don’t fit the blind back to front. Place your first bracket in the position you wish to fit the blind to. Ensure your blind won’t get in the way of any handles or vents and adjust the positioning of the bracket to accommodate this.
Measure the distance from the window to the bracket and mark the spot you need to drill, and repeat this on the other side, ensuring the brackets are level (a spirit level can help gauge this). Drill the hole, starting with a smaller pilot hole and then going to the wider 5mm drill bit. You should use a thin wood drill bit if attaching it to the window frame and consider using the smaller screws supplied. If you are fitting the blind to the wall, use a masonry drill bit with the wall plugs supplied (make sure the drill bit and the wall plugs are the same size).
The alternative way of installing your blind is to attach these brackets to the ceiling or top of the recess with the blind hanging below, which is known as top fix. Again, drill a pilot hole first before using the wider drill bit and relevant wall plugs.
Important Note: Ensure there is enough space at the pin-end bracket (the end opposite the mechanism) to allow for free movement of the barrel. The pin-end of the blind is sprung to allow for easy removal of the blind and should not be fully compressed as this can cause the barrel to rub on the bracket and make operation stiff. This can result in the blind being hard to operate and for the chain to break.
Once the brackets are up you can add the bracket covers if you ordered them. These optional extras will simply slide onto the brackets, giving your blind a professional and clean finishing touch if outside of the recess. The bracket covers are designed to have a nice tight fit, if you ever need to remove them insert a flat screwdriver into the cutout at the bottom inside of the cover and twist, this will release the cover. Note: If you wish to use bracket covers on a blind going into the recess, be sure to account for the size of the cover before screwing in the brackets as it might be a tight fit.
Now it is time to fit the blind. First, attach the end opposite the controls (known as the pin-end), push gently against the pin-end to suppress the pin, lift the control end up and attach to the control end bracket.
Depending on the control type you selected from your blinds - the next steps will differ, but we've got you covered...
Standard Roller Blindsattach the relevant child safety devices. The cord retainer should be at the maximum distance possible from the control mechanism, keeping the chain taut (but free enough to operate the blind smoothly). Put the retaining device on the wall, mark the hole with a pencil, drill the hole, insert a wall plug and screw the device to the wall. And there you go – your blind is safely up, so all that’s left is to give it a quick test.
Crank Operated Roller Blinds
Unpack the crank handle and attach the hook on the end of the handle to the eyelet on the blind’s mechanism. The crank handle is designed to fold out to create a handle to easily rotate the shaft, thus operating the blind smoothly and easily. If the blind is top fix, the pole clip should go within the recess to keep the crank handle out of the way, or on the wall close to the edge of the blind if it is a face fix blind. This is attached easily: simply mark on the wall with a pencil where you wish to hang the crank, drill the holes and insert a wall plug into each hole and screw the device to the wall!
Changing the Roll
If you wish to change the way the blind is rolled, which is sometimes a good idea if you are trying to avoid window handles or other protruding objects, then simply unravel the blind all the way to the metal barrel and then re-roll it in the direction you want. Note: Make sure your hands are clean, you wouldn’t want to mark you nice new shiny blind! It’s also a good idea to have your hands at equal lengths to ensure that when you re-roll the blind the roll is even, this will prevent any gather at one end and exposed barrel at the other.

A fire retardant blind will only smoulder when presented with a flame and will self-extinguish once the heat source has been removed. This can be added to your fabric by selecting this add-on at the checkout
All our blinds come with child safe features as standard but some are inherently more child safe due to the deliberate removal of chains and cords.

Wider width option
We can make this roller blind to a width of 3450mm and a maximum drop of 4250mm. This is above the sizes offered by many other retailers and this is because we automatically upgrade the barrel and mechanism to a more heavy-duty type to accommodate the extra weight from the fabric – at no hidden cost to you.
There is a chance your extra wide roller blind will have a join in the fabric running horizontally near the top of the blind. For wide blackout blinds particularly, this join is welded to ensure no light can get through.
