Roller blinds are a multifunctional part of the decor. Unlike classic curtains, roller curtains take up much less space, require minimal maintenance, and most importantly, have no less light transmittance. But when purchasing this fashionable novelty, you should know for sure which size is right for you. Many people are faced with the problem: how to take the correct measurement? In this article we will try to figure out what's what with you.

How to take the correct measurement

First of all, it is worth noting that the size of the future roller blind depends on the dimensions of your window, as well as the shape of the structures on the double-glazed window. It is important to remember that the purpose of your measurements is to determine the future width parameters of your roller blinds, since roller blinds are most often about 2 meters long (which should be enough for most modern models window structures).

Measuring the window

  • First, we measure the glass in width and height (along the sash). Knowing this parameter will allow you to determine what the minimum width and length of the future roller blind should be (for example, in the photo below).

It is necessary to measure the length and width of the window

    Secondly, you need to measure the depth of the bead (this detail is shown in the photo below). Knowledge of the data obtained will allow us to determine which roller blind system will suit us best. So, if the depth of the glazing bead is more than 1.5 cm, it means that the “Uni” type roller blind system is suitable for you. And if the bead depth is up to 1.5 cm (inclusive), then the “Profil” (profile) or “MINI” (mini) system is better suited.

Not only plastic, but also standard wooden windows are suitable for the above described manipulations.

Important advice: keep in mind that according to production parameters, the width of the curtain is considered to be its overall width, that is, the cornice or, figuratively speaking, a “tube” that contains a rolled curtain roll, and this element is always wider than the fabric itself.

Choosing a roller blind system

MINI system

MINI roller blinds are a classic model with a small shaft. Due to the compactness of the shaft, such curtains can be mounted directly on top of the sash. The fastenings are installed without any mechanical intervention, which preserves the integrity of the frame, and therefore its aesthetic appearance in the future. Even if the roll in such a curtain turns out to be longer than the height of the glass, the extra centimeters can simply be cut off.

A special metal strip and magnetic holders in such models ensure that the rolled fabric is fixed on the sashes so that there is no sagging. The magnets are attached to the frame using double-sided tape. The doors themselves can open in any plane.

The advantages of the MINI system are affordable price and compactness, which creates considerable demand for such curtains. True, this model will not provide a high level of light resistance. There may be gaps on the sides of the glass through which sunlight will pass through.

The correct measurement for curtains of the MINI system is as follows:

  • Measure the glass for width, then for height up to the sash. Write the obtained data in millimeters. Add 30 mm (3 cm) to the obtained width values, and 120 mm (12 cm) to the height data.
  • Also determine for yourself where you would like the curtain control mechanisms to be located (we recommend sticking to standard standards - that is, rely on the control chain near the hinges)
  • Select one type of fastening (screws, hanging bracket, adhesive tape)

Installation of curtains of the “MINI” system is carried out only on the doors.

UNI system

Quite a popular system, because it fits very organically into almost any interior, convenient and practical to use. Well suited for rooms where there are already curtains or tulles.

The roll is in a special plastic box and is controlled using a chain. This system takes into account the possibility of fixing the roll at any level. A chain holder is also provided.

The structure itself is attached to both sides of the window sashes, where metal guides are installed along the glazing beads, along which the roll stretches when lowered and raised. Installation on a window opening is also possible.

The system in turn is divided into types UNI-1 and UNI-2

    UNI-1. It can be used regardless of the window structure, and also has an attractive appearance. This advantage gives it impressive popularity. If you wish, you can choose the color of the box in the same tone as the frame, which will provide a combination that is pleasing to the eye. A typical example of the UNI-1 system is a 200x175 roller blind shown in the photo below:

The measurement algorithm for this system is as follows:

  • The height is measured along the edges of the bead + 20 mm is added to the value (as a reserve due to the size of the cornice)
  • The width is also along the edges of the bead (nothing is added to the resulting value)

It is worth noting that due to the simplified design of UNI-1, friction of the lower part of the curtain (slat) on the glass is often observed, which leads to unwanted bevels, which means cracks are formed. A similar phenomenon is observed where the bead depth is about or more than 20 mm (2 cm).

  • UNI-2. A more universal subtype, aimed at eliminating the problems of friction against glass and bevel of the plank by allowing it to be mounted on any surface, regardless of the “relief”. Suitable for windows with any glazing bead depth, especially for those where it is more than 20 mm. Thanks to the U-shaped vertical guides, the curtain is always in a clear position and does not rub or become beveled.

The measurement algorithm for UNI-2 is as follows:

    Measure the width according to the external dimensions of the roller blind guides (you need to know at the front which model and what sizes you want to buy)

  • The height is also determined by the external dimensions + the box height of 70 mm (7 cm) is taken into account. Experts recommend purchasing a product with a height reserve of + 10-20 mm (1-2 cm), since in case of an error with the dimensions, the plugs are removed from the guides and cut to height.

Profile system

This system is suitable for windows with slightly thickened frames, rounded or shallow glazing beads (up to 1.5 cm in depth). The design feature is that it is mounted at a distance from the glass. The guides are U-shaped, which ensures good fixation of the fabric as it moves. The curtain is controlled using a special chain, and the fabric can be fixed at any level.

Correct measurements for this system:

  • We measure the latitude at horizontal angles from sash to sash.
  • The height is measured taking into account the size of both the glass and the entire sash that opens.

Installation of the “profile” system is possible on a window opening, on a sash, and would even be appropriate on a door.

Alternatives

If none of the types of roller blinds discussed above satisfy your aesthetic tastes, but at the same time you are not deprived of the desire to acquire blinds on a woven basis, then know that there is a way out. Its name is Roman blinds.

Even if you are not picky in your choice, and you also like the roller version, it is still important to note that for balconies, for example, roller blinds will not work well, given the traditionally large width of balcony glass and their number, but Roman blinds will come in handy here. True, the recommendations described below are suitable plastic windows.

Considering the volume of such a curtain, it can be installed both on the sash and on the opening, and even on three- or four-leaf windows. The main thing here, again, is to take correct measurements:

  • Roman blind for the doorway. “Latitude A” is measured by the width of the fabric. Here you should know that the fabric itself is already finished product by 20+ mm (take this difference into account). “Height B” is measured in accordance with the length of the finished product (without additional calculations)

We take into account both width and height

    On the sash. The width is measured along the outer edge of the bead (again, we take into account the 20+ mm additional width of the product in relation to the fabric, and we also take into account the location of the window handle). Height is measured according to the height of the finished product.

  • For triple-glazed windows and more, Roman blinds are usually made to order, although some manufacturers already have ready-made models. Here the following are taken into account: the number of folds of the Roman curtain in height; as well as the results of measuring the lower and upper edges of the curtains at one level to the sashes of each window (so that the fastenings of the Roman blind rods are symmetrical)

On large double-glazed windows, the problem of curtain symmetry is very relevant

If some aspects of determining the dimensions and installing roller blinds are not clear to you, we recommend watching video tutorials and video instructions on the Internet by simply typing into the search: “how to measure a roller blind.”

Curtains classic cut always relevant. But they do not always suit the interior of the room or are not to everyone’s taste. In such a situation, the only correct solution is roller blinds. This type of curtain is a piece of fabric that is attached to the top of the window on a shaft. Basically, it spins from top to bottom. The main lifting mechanisms in such products are mechanical and automatic. An automatic lift is more convenient than a mechanical one, but, unfortunately, it is much more expensive.

Before you buy roller blinds, you need to correctly measure the dimensions of the window.

Roller blinds come in two main types:

  • closed;
  • open.

The mechanism of open roller blinds is much simpler, since it does not have a shaft on top that protects the fabric. They cost an order of magnitude cheaper, but they also get dirty more often. Closed curtains have a protective roller and most often they are equipped with an automatic lifting mechanism. The cost of roller blinds depends on the quality of their components. Besides, this type Products may vary in color and type. It is very difficult to make roller blinds yourself and therefore it is better to order them, taking into account the size of your window.

They can be multi-colored or plain. The materials from which they are made are very different. In a separate group there are curtains called “Day-Night”. They consist of two strips of fabric. When closed they look like a single unit.

Selection criteria

When it comes to replacing old windows with new ones in a house, the question involuntarily arises about decorative components, more precisely, about curtains or blinds. With the advent of plastic windows, it has become fashionable to use roller blinds in the interior. They are much more practical and modern. You need to choose roller blinds for your room based on a number of criteria:

  • is your side sunny?
  • what density of fabric is required;
  • type of fastening - on the sash, window frame, on the wall, in the slope or ceiling;
  • open or closed system;
  • choice of fabric color.

All these points must be taken into account when choosing roller blinds.

Fabric selection

Fabrics for roller blinds can be divided into four groups according to material density:

  • First group- These are light translucent fabrics. They do not provide significant darkening, but play more of a decorative function. These fabrics should be used when it is necessary to achieve a slight darkening effect and use the product only as an element of window decoration. Translucent fabrics are produced mainly with patterns.

  • Second group– dense fabrics that provide significant darkness in the room. They can be either patterned or plain. They should be used in moderate sun. They have both a decorative and sun protection function.

  • Third group- These are very dense fabrics. Products are best used in very strong sun, for example, if you have a south-facing window or a large window. In addition to their sun protection function, they are also used as decorative element window decoration. These fabrics come in patterned and plain colors.

  • Fourth group– blackout fabrics, or complete blackout. They come with a pattern and plain ones. When a roller blind made of this fabric is lowered, even in the middle of the day when the sun is shining, your room will be completely dark.

Types of fastening

We've decided on the fabrics. Now you need to figure out how the roller blind should be attached. If you already have regular curtains or tulle hanging, then the best option for attaching the roller blind is to the sash or to the window frame. If there are several sashes - two, three or more, as, for example, on a balcony, it is better to install the curtain on each sashe separately. It will be more convenient.

If you don’t have regular curtains or tulle at all, or you plan to remove them, then the option of mounting a roller blind on the wall (like a regular cornice) or mounting it to the ceiling will suit you.

Although the first option of mounting on the sash or window frame can also be considered. For example, in the kitchen, instead of regular tulle, because it constantly gets dirty, you can use a closed system of roller blinds. The shaft with the fabric is covered with an aluminum box matching the color of the window, and aluminum guides also matching the color of the window are placed along the edges. They serve to secure the fabric.

Due to the fact that a product with a closed system is attached directly to the window, it is completely removed from the main sources of pollution, such as the stove and sink. That is why the product will last a long time even without additional cleaning.

Measurement Rules

To select and buy suitable roller blinds, you need to measure the window correctly. To do this, you need to find out the following parameters:

  • Width. For correct measurements, indicate the width from the joint of the bead to the frame on one side, and the joint of the bead to the frame on the other side - this will be the width of the fabric. In roller blinds with an open type mechanism, the overall width of the roller blind will be 38 mm larger than the width of the fabric due to the upper side mounting fasteners. The roller blind measured in this way completely covers the double-glazed window and the window bead, which ensures maximum overlap of the opening.
  • Height. To correctly measure a fabric roller shutter, indicate the size from the joint of the bead to the frame at the bottom to the joint of the bead to the frame at the top. The size of the roller shutter mechanism is added to the height of the fabric and is about 70mm (36mm roller shutter +34mm bottom space).

It is worth paying attention to the depth of the roller blind mechanism, which is approximately 36 mm. It is necessary to take into account the distance from the edge of the roller shutter mechanism to the slope. The opening angle of the window depends on this distance.

To correctly measure the width of roller blinds with flat guides, it is necessary to measure the following parameters:

  1. The width of the opening at the junction of the glazing bead to the double-glazed window (width of the fabric).
  2. Width along the edge of the bead (width of the box).
  3. Bead depth. It must be at least 10 mm, since the fabric should not touch the glass unit.
  4. Bead width. It must be greater than 10 mm, since the minimum width of double-sided tape for guides is 9 mm.
  5. Height. To correctly measure the roller shutter fabric, indicate the size from the joint of the bead to the frame from below to the joint of the bead to the frame from above.

It is worth paying attention to the depth of the roller shutter box, which should be 36 mm and a height of 70 mm. It is necessary to take into account the distance from the edge of the roller shutter mechanism in the slope, since the opening angle of the window depends on this distance.

To measure closed roller blinds with U-shaped guides, you first need to find out the width. For correct measurements, indicate the width from the junction of the bead to the frame on one side, and to the junction of the bead and frame on the other side - this will be the width of the roller shutter along the edge of the guides. The overall width of the roller shutter will be 20 mm wider than the guides.

To correctly measure the height of a fabric roller shutter, indicate the size from the joint of the glazing bead and frame at the bottom to the junction of the glazing bead and frame at the top. The distance from the slope on top of the window frame to the junction of the glazing bead and the frame (for fixed windows) must be at least 35 mm.

Designers prefer to use roller blinds in modern home interiors. They are especially suitable for residential premises where active people with a modern outlook on life live. Their advantage is that you can choose any pattern, design and high-quality fabric for production.

To learn how to install a roller blind on a plastic window, see the following video.

Such products, as a rule, have a compact shape, their length does not fall below the window sill, while the panel fits tightly to the glass, occupying a minimum of free space, which allows the window sill to be used for functional purposes.

However, there are also roller blinds large sizes, designed for panoramic windows. They are fixed under the ceiling and unfolded to the entire height of the wall, to the floor.

The main emphasis in such curtains is on their functionality - it is in rolled products that the most modern fabrics are used - blackout, dimout and “day-night”.

Blackout textiles, thanks to the presence of two reflective pads, ensure complete darkness of the room, while dimout fabric, on the contrary, transmits sunlight, but filters ultraviolet rays that spread heat, which guarantees a pleasant coolness in the room even during the hot summer.

Day-night curtains combine the advantages of the two above fabrics; such panels consist of alternating strips of dimout and blackout materials, the position of which can be adjusted, thereby setting the desired level of lighting in the room.

Design features of roller blinds

The roll product system of any type has a standard design consisting of:

  • The upper shaft, when rotated, the curtain unfolds. The shaft can be open or closed. In closed structures it is hidden inside a box fixed to the window frame. The cases are distinguished by a variety of shapes - they can be rectangular, oval and triangular, and are made of materials - plastic, aluminum, wood.
  • Vertical guides installed on the side edges of the window. They are necessary for uniform deployment of the curtain and for holding the fabric when the sash is opened for vertical ventilation. Guides can be heavy - from plastic strips, and light - from ordinary fishing line.;
  • Canvas with a weight strip sewn into the lower part.

Let's consider how to measure a window for roller blinds for each mounting method.

Installation over the opening

First of all, you need to measure the window for roller blinds according to parameter F - the distance between the upper contour of the opening and the ceiling. You can install a curtain in this way only if the size of this area exceeds 70 millimeters, otherwise you simply will not have space to install the box.

Sash mounting

Roller curtains of the Mini class are installed on the shutter - these are the simplest products without side guide strips.

  1. We determine the width of the glass - the width of the canvas should exceed it by 6 centimeters so that the fabric, due to the margin of 3 cm on each side, completely covers the window;
  2. Mini curtains come with standard mounting corners with a width of 2 cm; add an additional 4 cm to the width of the curtain and you will get the required overall width of the product;

Determine the length of the control chain - it is usually 2/3 of the total height of the canvas

For those who live in Odessa, we measure roller blinds free of charge, provided that you place an order with us. If we arrived, measured it, and you said “we’ll think about it,” then such a measurement trip will cost 100 UAH (in Odessa). If you are still determined to order from us, then these 100 UAH will go into the cost of the order, and the measurement in this case will become free for you. Here on the website, the price is indicated for one roller blind made of this fabric, in the Mini 19 open system on a fishing line, which is attached to the window sash, or its blind part with minimum design dimensions, i.e. width 50 cm. This does not mean that a roller blind cannot be made smaller than 50 cm, you can make it at least 25 cm in width, but its cost will be calculated as 50 cm. The price changes every 5 cm in width. To find out the cost of curtains for your windows, you need to place an order on our website, indicating the fabric from which you want to make roller blinds for yourself, leave your contact phone number, and a manager will contact you and calculate the curtains according to your sizes. Call us at the numbers listed in the contacts section and calculate the curtains according to your sizes, or write a letter to us indicating your sizes.

Now about how to measure.

Let's start with the simplest system - this open system Mini 19 with fixation on a fishing line or magnet, you can do cable fixation (at an additional cost) and the M 25 system (they are similar). This system is suitable for almost all types of window profiles, and generally does not depend on the shape of the glazing bead (rectangular, shaped, rounded).

What sizes are needed? The most important size here is width. The width is measured as follows: the width of the double-glazed window + the width of the bead, i.e. we need the joint of the bead with the frame, where the bead enters the frame (from this joint on the left side to this joint with right side).

In height, we measure the entire sash or blind part from top to bottom as shown in the figure below. These will be the dimensions of the roller blinds according to the fabric!

BUT!!! You should know that in a roller blind Mini 19 the fabric size is smaller in width than the overall size of the curtain by 33 mm. See picture.

It follows from this that on the window sash or blind part there should be a distance where the roller blind brackets can be screwed on without any problems. As a rule, such problems do not arise on a sash window, because There is always a place there, but sometimes problems arise in the remote part of it.

Let's consider the options.

Let's look at the right side of the window, that is, the blind right side. What we see: There is a loop on the left side and a slope on the right side. Our task is to place the roll between the loop and the slope. On the hinge side, as a rule, there is 8-10 mm left before the joint of the glazing bead with the frame, distance A. Sometimes it is less, but very rarely. After we have measured the size of the fabric for the roller blind at the joints of the glazing bead with the frame, it is still tedious to measure the size from the top loop to the beginning of the slope. If, for example, we have a size of 50 cm at the joints of the glazing beads, then in order for the dimensions of the roll to fit, we need another + 3.3 cm, that is, if we have a distance from the top loop to the slope of more than 53.3 cm, then the roll will fit without problems . If it is less than 53.3 cm, then we reduce the size of the roller blind, and we need to look at whether the fabric will overlap the glass. But this happens rarely, mostly everything is fine.

The next system is M32, designed for large windows, mounted on the opening or in the opening.

If you want to install a roller blind on a window opening, then you need the following dimensions:

opening width (from slope to slope) + at least 10 cm (to cover the opening with fabric 5 cm on each side),

opening height (from the slope to the window sill, or to the floor) +5 cm

If you want to install a roller blind in a window opening, then you need the following dimensions:

width - from slope to slope, in the place where the roller blind will be installed, height from slope to window sill or floor.

The width will be the overall size of the roll, i.e. size at the edges of the bracket, the fabric size in this case will be 35 mm

If you want to take measurements and install M 32 on large windows, then follow the instructions for Mini 19, only here is the overall size of the curtain smaller size fabrics at 35 mm.

Closed system of roller blinds (cassette system) Uni-glazing bead.

This system is not suitable for all types of glazing bead!!!

Suitable for rectangular beads (angle 90 degrees), or the bead has a slight bevel, and the depth of the bead must be at least 12 mm.

What does the glazing bead look like:

If your glazing bead has exactly this shape, then the Uni-beading system is suitable for you. If there are deviations from what is shown in the photo, for example, the bevel angle is large, or you have a 2-chamber (3 glass) double-glazed window, do not take risks, install a Uni-sash.

The dimensions needed for the correct manufacture of roller blinds are the same as in Mini 19.

The width from the junction of the bead with the frame, to the junction of the bead with the frame, the height is the same.

Closed system of roller blinds (cassette system) Uni-fold.

The system is designed for installation on the window sash and its blind part where there is a non-standard glazing bead.

What is a non-standard glazing bead? This is a rounded, figured glazing bead with a large bevel.

How to make an accurate measurement? If we have a rounded glazing bead, and we need to glue a guide, then we need to look for a flat surface, and it usually begins immediately after the rounded or shaped bead enters the frame.

We measure this distance, essentially it turns out from the joint of the bead with the frame, to the joint of the bead with the frame + 3 cm (1.5 cm on each side), this is the so-called overall dimension along the guides, which is also our width. Please note that the overall width of the cassette is 18 mm larger than the overall size along the guides.

In the picture X this is our width for calculations.

Another important point! on the handle side of the sash, as a rule, there is not this 15 mm flat surface, there is approximately 8-10 mm there; it will be enough to glue the guide, that is, on one side we add 8 mm (or 10 mm) and on the other side 15 mm .

Now with height. What makes this system unique is that the height can be made the same on both the blind part and the sash.

Let's look at an example.

In this figure, we measure the height on the blind part of the window from the junction of the glazing bead with the frame to the junction of the glazing with the frame - this will be the overall height of our curtain. We make the same height on the sash. Then, during installation, we use a level to transfer the line of the upper junction of the glazing bead with the frame to the sash, in the figure it is indicated by a dotted line, this will be our upper attachment point for the roller blind.

Ready to buy roller blinds, but can't decide on the size? Take 1 minute to read the instructions from the online store “Curtains for the Home”, and the size of the roller blind you need will not be a problem.

It is not necessary to contact a specialist - why waste time and money? Determining the size is easy - for this you will need a tape measure, a pen and a sheet of paper.

For convenience, you can download special form-memo to record the calculations that have been prepared for you.

So let's get started:

  1. We measure the width of the glass in the frame.

2. Add 2-4 cm so that the curtain reliably blocks the flow of daylight.

Please note that if there is a handle on the sash, then we make an indent at a distance from the handle on both sides so that the curtain fabric does not interfere with the opening of the window.

3. There is no need to measure the length of the window sash glass, because The roller blind fabric has a standard length of 160-170 cm and can be adjusted by you as desired.

However, if you choose a ready-made roller blind for the balcony door, then it has standard size 68*215 cm. The width of such a roller blind can be easily changed using a hacksaw and scissors. And the height can be adjusted according to your wishes.

4. Select the size of roller blind you need in the catalog or on the product packaging.

We hope that you did a great job with the measurements and are ready to purchase roller blinds. More more information about curtains and textiles on our channel.
