Blackout blinds are an amazing way to maximise the functionality of your room. From improving your sleep in the bedroom, to creating the best environment to watch your favourite films, blackout blinds will help you find peace after a long day. In this blog, we’ll be exploring the different types of blackout blinds you can enjoy alongside our top tips for fitting and maintaining your new purchases. 


What are blackout blinds?

Blackout blinds are specialist blinds that block as much external light as possible from entering your home. While useful in any property, they are particularly useful if there is a lot of light that continues into the night, for example street lights in the city, or proximity to a busy road where headlights affect your sleep. 
While supremely functional, there are so many stylish varieties of blackout blinds available that you don’t have to compromise on aesthetics. There is a dynamic and diverse selection of blackout Roman blinds, roller blinds, vertical blinds and pleated blinds that offer the twin benefits of beauty and functionality.

How to fit blackout blinds

Once your order has been made and delivered, the process of fitting blackout blinds begins. While different styles of blackout blinds require slight different processes, they are all easy enough to complete – even more DIY novices. 

To make the process of installing your blackout blinds as easy as possible, we provide every order with easy to follow instructions, but if you want to checkout the process before you order, you can find PDFs of all our fitting instructions here.

If you’re looking for added convenience and a modern edge to your space, you can consider motorising your new blinds. Electric blinds improve the comfort of any space but they will require an additional set up process. This is extremely easy to do and instructions will be provided alongside your order. You can learn more about smart blinds in our electric blinds buyer’s guide.

How to measure for blackout blinds 

After deciding which style of blind you’d like, the next step in enjoying your new blackout blinds is to measure the window. 

Measuring a window for your new blinds may seem a daunting task, but it needn’t be! The first decision to make is whether your new blackout blinds will fit inside (recess fit), or outside of the window’s recess (exact fit). Once you’ve picked an option, you follow the easy steps below – what could be more simple? 

Recess fit – Measure the width and the drop in three different positions ensuring you provide us with the smallest measurement. We will make any necessary deductions to ensure the blind fits neatly within the recess of the window. For roller blinds we only require you to measure the top width of your recess. Please provide this when placing your order.

Exact fit –  An exact size blind is also known as ‘pin width’ or ‘finished blind width’. This is the measurement you need to make if the blind needs to hang outside the recess overlapping the window. Decide how much you wish to overlap the recess at each side, we recommend at least 7.5cm at each side as well as the top and bottom so as to minimise as much external light as possible. Measure the width and the drop in three positions ensuring you supply us with the smallest measurement. We will not make any deductions from the measurements provided.

You can learn more about measuring your windows in our Expert Guide: How To Measure For Window Blinds. Also note, if you’re not 100% confident in measuring your windows, you can take out our Surefit guarantee for greater peace of mind.

How to maintain blackout blinds

How to clean Roman blinds – Proper care and maintenance of Roman blinds is essential. Regular dusting and vacuuming alongside spot cleaning when required will keep your blinds looking fresh and stylish. Additionally, if needed, you can have your blackout Roman blinds professionally cleaned. You can learn more in our Expert Guide: How To Clean Roman Blinds

How to clean roller blinds – Roller blinds are functional, attractive and affordable. They’re also very easy to maintain. By using a vacuum cleaner on a low setting, a damp clean cloth or a silicon spray on the header if required, you can keep blackout roller blinds looking perfect effortlessly. All the information you need to keep your blinds looking pristine can be found in the Expert Guide: How To Clean Roller Blinds.

How to clean vertical blinds – Vertical blinds are a sleek, fashionable option for a home. That said, their sheer size can cause customers to worry about maintenance and cleaning. If you’re stumped about how to clean your vertical blinds, don’t be. Whether you need to do a spot clean, or a deeper clean, you can find everything you need to know in the Expert Guide: How To Clean Vertical Blinds.


Blackout blinds are a practical investment that offer significant benefits in terms of style, privacy, and enhanced sleep quality. By carefully measuring your windows, following the instructions, and our maintenance tips such as regular cleaning and prompt repairs, you can ensure your blackout blinds remain functional and aesthetically pleasing for years to come.
