247 Pro Tips:

It is best to measure for your recess using three measurements for the width and the drop, using the smallest of each as the final size.
When measuring to fit inside the recess, be aware of anything that may get in the way. If you have tiling or picture rails around the bottom of your recess, which is 20mm or less difference to the width across the top, we advise that you provide the measurement across the top for a nice, snug fit!
If your recess depth is 60mm or less or the window opens inwards, you'll be best off with an exact fitting. To do this please follow the 'Exact' measuring method in our measuring guide.
For the best results when measuring for an exact fitting, allow your blind to overlap the edges of the recess by at least 35mm on each side. We'll then make a blind for your exact measurements and ship it with the brackets, which will add another 3mm to the size you give us.

Additional Information:

The fabric width is 35-40mm narrower than the overall width of the blind to allow for any control component on the side of the tube (or 'cassette'). We always manufacture the full blind width and not fabric width. If you are fitting one of these blinds outside of the recess, you may want to consider measuring wider to allow for some fabric overlap.
We try to make the measuring and ordering process as simple as possible - so for a recess fitting, we only require the full size of your recess space and we will make small adjustments to enable the blind to fit within that space. We make a 3mm deduction to the width of Roller blinds. If you wish to make your own allowances and do not require us to make them, please select exact fitting and not recess during the order process.
If you are fitting a roller blind inside of a recess and wish to mount the brackets to the sides of the recess (opposed to the lintel or window frame), please make sure that you measure across the top of the recess and select 'exact' instead of 'recess' to allow for this particular type of mounting (otherwise 'top' or 'face' fixing is an alternative option).
To ensure accurate measuring for bay windows, please consult our Bay Window measuring guide or for more help with measuring for blinds, or getting a perfect fit, take a look at our simple step-by-step demonstration videos in our video section.
If you are still unsure about your measurements, then don't worry, just put your mind at ease and consider adding our 'MeaSUREguard' protection to your order. For just an additional 10% charge, we promise to replace or alter your blinds if you find that you have made a mistake with your measuring. Available on all made to measure blinds at the checkout.

Frequently asked questions about this product

Will this blind type be suitable for my room?

Yes! A blackout roller blind is a great, versatile choice for any room in your home. Blackout fabric is known for improving your sleep hygiene, thanks to its light-blocking feature, and is good choice for rooms with screens like bedrooms or living rooms.

The images and sample show blackout - Is this my only option?

Our William Morris At Home Waltham Roller Blinds feature classic plain designs printed exclusively on blackout fabric, enhancing colour richness while providing effective light-blocking to protect your interiors from sun damage. By using only blackout material, we ensure the colours appear bold and true, just as shown in our product images—giving you a clear, accurate preview before you buy.

Will this blind blackout my room?

Short answer is yes, however please be aware that because of how roller blinds are made, you might notice a small gap at the sides where light can seep through – this is completely normal and common across the industry. However, the blackout fabric itself is fully light-blocking, meaning no light passes through the material, making it ideal for bedrooms and anyone wanting a great night’s sleep.

Will the colour differ on each fabric?

Due to the nature of the printing process, there are minute differences between how the colour will print on each base cloth. Generally speaking, blackout fabrics absorb the colour and don't have the natural light-filtering properties compared to the standard light filtering material. Due to this, the colour can appear more 'saturated' compared to the light-filtering option.

How do I clean my roller blind?

Luckily, roller blinds are one of the easiest styles to clean! For blackout fabrics, we would recommend a slightly damp cloth to gently wipe or remove the mark.

How is the bottom of the blind finished off?

The bottom of this roller blind will be a double-wrapped bottom bar. This means the fabric hides the weighted bar on the front and back, with the fabric wrapping around both sides. This will create a more cohesive appearance.

What are Twist&Fit Roller Blinds?

The standout feature of Twist&Fit roller blinds is their no-drill, easy installation process. They can be fitted in under 30 seconds without the need for tools, drills, or screws, ensuring your walls remain untouched. We provide the same great fabrics, quality and durability as our well-loved roller blind ranges.

Will my window be suitable for Twist&Fit?

Twist&Fit roller blinds are suitable for windows with a recess depth of at least 52mm. As Twist&Fit blinds are designed to fit snug within the recess, they are not available for exact fitting. It is not possible to fit more than one Twist&Fit blind within a singular recess.

Do I need screws for Twist&Fit rollers?

The great thing about Twist&Fit roller blinds is the ease of fitting and special tension system which provides an easy, screw-free installation. Available for recessed windows only, your new blind can be fitting in 30 seconds or less — it’s that easy!
