Purchase and evaluation criteria for blackout curtains

In the following we would like to show you which factors you can use to compare and evaluate blackout curtains. This will make it easier for you to decide whether a particular blackout curtain is right for you or not.

In summary, these are:

In the following we explain to you what exactly these individual criteria mean.


To find out what dimensions the blackout curtain should have, you have to correctly measure and calculate your window. You can calculate the width of the curtain as follows:

Curtain width = width of the window * gathering (1.5 - 3 times)

You should also add 10-20 cm on each side so that there is no gap between the wall and the curtain. This is how you achieve the maximum darkening effect.

It is best to measure the curtain length to the right, left and in the middle of the curtain, as this can lead to different results. Then select the smallest value as the length.


There are a few things to consider when choosing the right material for your blackout curtain. The following tips can help you choose the right material:

  • Make sure that the material is made up of three layers. The middle layer of blackout curtains is black and absorbs the light. You can choose any color on the outside.
  • A firm fabric is important for the opacity of the curtain. Even materials with just one layer are so opaque.
  • The curtain should also be flame retardant for safety reasons.
  • An extra coating of the curtain can help to repel heat and thus keep the room pleasantly warm or cold, depending on the season.

Blackout effect

You can choose between different darkening effects in stores. Some curtains darken the room 100%, others e.g. only 90%.

If you want to use the curtain overnight, a 90 or 95% darkening is a good idea, because this way some light comes into the room in the morning and you wake up easier.

For a particularly strong darkening effect, the curtain should consist of three layers. The outer layers are in a color of your choice, the inner, invisible layer is black and absorbs the light.


Many manufacturers point out that the color of the curtain affects the darkening effect. Depending on the material, lighter fabrics darken the room much less than darker fabrics. When choosing the color, follow the manufacturer's instructions.

Light curtain colors are generally suitable for small rooms. This makes the room look bigger and friendlier. In large rooms, on the other hand, darker colors can add a nice accent. You should therefore use dark colors, especially in large bedrooms where a strong darkening effect is desired.


Blackout curtains can be attached to a curtain rod in different ways. With the help of hooks or rings, they can be hung on the curtain rod, for example. There may be additional costs because the hooks or rings are not always included in the package when you buy.

Mounting typeDetails
Blackout curtains with hooksAttachment to the curtain rod using additional hooks or rings
Blackout curtains with eyelets The eyelets or loops are sewn directly onto the curtain

In the case of blackout curtains with eyelets, these are sewn directly into the curtain fabric. So you don't need any extra accessories, you can hang up the curtain directly. There are also models that have loops attached to the top of the curtain instead of metal eyelets. If you already know before you buy that you will be sliding the curtain back and forth a lot, you should make sure that the loops slide smoothly on the curtain rod.

Buying Guide: Questions to Consider Before Buying a Blackout Curtain

What is a blackout curtain?

A blackout curtain is a short or floor-length curtain that shields the living room or bedroom from the incidence of light. While conventional curtains are often sewn from thin, light material, the blackout curtain is made from a particularly opaque and opaque fabric.

In addition to its functionality as a blackout curtain, it can also be used as a beautiful design element. Blackout curtains no longer have to be dark and heavy as they used to be, but can now also be purchased from lighter fabrics and in different patterns.

Who are blackout curtains for?

One function of the blackout curtain is already in the word: It protects against incidence of light. But the blackout curtain can offer you even more:
  • Blackout
  • privacy
  • Soundproofing
  • heat protection

This makes the blackout curtain ideal for people who work at night. Especially if there are no built-in shutters, the blackout curtain can still be used to sleep undisturbed during the day.

It is also suitable for the children's room: so the little ones fall asleep quickly even at lunchtime. For the children's room, there are also blackout curtains with a particularly beautiful design, such as detailed cut-out patterns.

Did you know that there are also special blackout curtains for on the go? If you don't want to miss out on your deep sleep in holiday accommodation either, you can take a travel blackout curtain with you. This can be folded up small and easily attached to the windows on site.

In winter, the blackout curtain ensures that the heating air stays in the room and does not escape through leaky windows. But even in summer, the blackout curtain helps you to keep a comfortable room temperature. If the curtains are drawn in the morning, they protect against direct sunlight.

What types of blackout curtains are there?

Basically, one can differentiate between two types of blackout curtains:
  • Blackout curtain for normal windows
  • Blackout curtain with suction cups

Depending on which type of window the blackout curtain is to be attached to, either a normal blackout curtain or a model with suction cups is suitable. In the following we give you an overview of the exact advantages and disadvantages of the two types of curtains.

Blackout curtains for normal windows

When we talk about normal windows in the following, we mean anything that is not a sloping or skylight window. Whether your window is floor-length, vertical or horizontal, first of all plays a role. It should only be installed in a straight wall without a slope.

Blackout curtains for normal windows look like normal, long curtains, but are made of an opaque material.

There are a wide variety of regular blackout curtains available both online and in stores. Regardless of the color of your walls or the pattern of your bed linen, you will find a visually matching blackout curtain.

You can also choose between different mounting options for blackout curtains for normal windows: They can be attached to the curtain rod using eyelets, loops or hooks.

Such normal blackout curtains are not suitable for sloping windows. In this case, they would not be in direct contact with the window and there would be gaps, which would allow light to enter the room. In addition, the normal blackout curtains have to be laboriously cleaned.

  • Large selection
  • Various mounting options
  • Can be designed individually
  • Cannot be used for sloping windows
  • Time-consuming cleaning
  • Cannot be taken on the move

Depending on the model, you can either put them in the washing machine or take them to the dry cleaner. Since the curtains are large and heavy, they cannot be taken with you on the go.

Blackout curtains with suction cups

Blackout curtains with suction cups are attached directly to the window frame without drilling. When attaching, make sure the suction cups and window are clean. Since they can also be used when traveling, many manufacturers use a smudge-proof fabric that can be cleaned quickly.

You can use blackout curtains with suction cups to do the following:

  • Normal windows
  • Skylights / sloping windows
  • On the way / traveling

This makes them the real all-round talent under blackout curtains. Buying a blackout curtain with suction cups is particularly worthwhile for families with children. You can not only use it for a nap at home, but also take it with you to relatives or to a vacation home.

  • Attachment without drilling
  • Quick cleaning
  • Versatile use
  • Less design options
  • No complete blackout
  • Not decorative

Unlike regular blackout curtains, there is less choice of blackout curtains with suction cups. They often come in a single color, in dark tones and are therefore less decorative. In addition, you can only achieve complete blackout with a model that is exactly the right one for your window.

Since manufacturer specifications are not always accurate, you may have to try out a few curtains until you find the perfect dimensions for your window.

What do blackout curtains cost?

It costs different amounts depending on the type of blackout curtain. Blackout curtains for normal windows are available from € 25. Special models with suction cups that can be used for skylights or on the go are available from € 30.
Type of blackout curtainprice
Blackout curtains for normal windows from 25 €
Blackout curtains with suction cupsfrom 30 €

Keep in mind that you will usually need two pieces per window, especially with normal blackout curtains. In addition, depending on the type of fastening, there are also costs for curtain rods, eyelets and hooks.

Where can I buy blackout curtains?

Blackout curtains are available for sale at many furniture stores. Carefully research beforehand which material is best for you so that it will be easier for you to search.

In some furniture stores, custom-made products are also possible. For this you simply select a type of curtain and your desired material and enter the dimensions of the window.

Blackout curtains are also available online. Here you will find a large selection of sizes, colors and patterns. Make sure to measure your windows carefully beforehand. Popular online shops for blackout curtains include:

  • amazon.de
  • bonprix.de
  • otto.de
  • baur.de
  • ebay.de

What alternative is there to blackout curtains?

Instead of a blackout curtain, you can also put a blackout blind on your window. Both blackout curtains and roller blinds are particularly suitable for bedrooms and living rooms.

In the bathroom, on the other hand, privacy films can also be attached for the window.

These only slightly darken the room, but ensure privacy, as the room can no longer be seen from the outside.

Blackout blind

A blackout blind has a better climate balance than a blackout curtain because it protects the room better from direct sunlight. Since most blackout blinds are made of water-repellent material, they can also be easily wiped off with a cloth. They are also barely visible during the day, as they disappear in the box at the top of the window.

  • Better carbon footprint
  • Easy cleaning
  • Barely visible during the day
  • Difficult to customize
  • Less blackout effect
  • No soundproofing

However, blackout blinds are difficult to adjust individually. You need to know the exact dimensions of your window to rule out a bad buy. If the roller blind does not fit into the frame, you cannot adjust it like a curtain with a needle and thread.

In addition, roller blinds darken less than curtains, as the blackout blind and window frame are often not flush. In addition, a roller blind does not offer any soundproofing.

How are blackout curtains washed?

In general, you should follow the manufacturer's instructions for washing. Most blackout curtains can be washed in the washing machine like normal curtains. Individual cases must be brought to dry cleaning. Professional cleaning makes sense even with heavy soiling.

Wash blackout curtains in the washing machine

  1. Remove all curtain fasteners before washing. Curtains that have sewn-in metal eyelets can be tucked into a laundry bag to prevent them from damaging the washing machine.
  2. The curtains are then washed at 30 - 40 degrees with mild detergent. They should only be spun briefly after the wash cycle. It is therefore best to turn off the spin function beforehand.
  3. After the short spin, the curtains are air-dried. Due to the special material and possible coatings, they must not be put in the dryer.
  4. Ironing is not possible with all blackout curtains. Pay attention to the care instructions regarding the setting of the iron.

What accessories do I need for blackout curtains?

Depending on which type of blackout curtain you have chosen, you will need different accessories. In addition, the sellers differ in what they deliver directly. Therefore, find out before you buy which accessories are not included with your blackout curtain and take these extra costs into account.

Accessories for normal blackout curtains

  • Curtain rod
  • Hooks and rings (if no eyelets or loops are sewn in)
  • possibly tiebacks to tie together during the day

Accessories for blackout curtains with suction cups

  • Suction cups (if not included)
  • Disinfectant wipes for cleaning the window before attaching the curtain
  • Scissors for cutting

Can I sew blackout curtains myself?

Of course, you can also easily sew blackout curtains yourself. If your blackout curtain is to be made of a certain material, going to the fabric store and sewing it yourself is a good idea.

In contrast to light curtains, you choose a heavy, dense fabric for the blackout curtain. This makes sewing easier because the fabric does not wrinkle and slip less.
