Determination of the required sizes of roller blinds

Roller blinds are an easy and inexpensive way to protect windows from daylight. Today many different types of roller shutters have been invented. They can be matched to any window and fit into different interior styles. But how to correctly determine the required size of roller blinds? Detailed instructions are given in our article.

Description and types of roller blinds

Roller blinds are a rigid fabric attached to a shaft. With the help of a special mechanism, the canvas rises up and rolls up. This design looks laconic and elegant on the windows. It does not require complex installation and is easy to maintain. We will understand the features of roller blinds, their sizes, what types of such products are.

Standard

Designed for double-leaf, standard windows of small dimensions. They can be mounted in or above a window opening. The height that roller blinds usually have is 2 meters. The maximum width can reach 1.7-1.8m.

The average shaft diameter is 25-30 mm. Fasteners and fittings are most often decorated in black, white, bronze, silver or have a transparent structure.

Suite

The shaft diameter is larger here than in the standard version. It can vary between 35-70 mm. Due to this feature, roller blinds can be large. Their maximum width is up to 3.5 m, and the width is up to 4.5 m. The design also allows you to attach even heavy-weight blackout fabric canvases. This type of curtain is suitable for windows in spacious rooms: offices, business centers, factories.

Mini cassette

They are mounted on window sashes. The shaft is very thin, its diameter is no more than 15 mm. When screwed onto the shaft, the canvas is hidden under a semicircular aluminum box. Very comfortable design. After all, it does not interfere with opening windows for ventilation.

The window sill space also remains uncovered. This makes it possible to use the window sill as a shelf for small items or a flowerpot. A good option for small rooms, where the issue of saving space is especially relevant.

Open curtains "Mini"

Like the previous type of curtains, it is mounted on separate window sashes. But there is a difference - the lack of guides. Thanks to this, the cost of curtains "Mini" is less than that of mini-cassette curtains. They are mounted either on plastic brackets or by drilling frames. The first option is only possible if the flaps open. It is impossible to install brackets on blind windows. We'll have to drill the frames.

According to the degree of light transmission, there are such types of roller blinds:

• Transparent. They let in daylight well. They must be complemented with curtains and tulle. The main role is decorative.
• Dimaut. Partially let in daylight. They can also trap heat. They are used in offices, as well as small conservatories, greenhouses.
• Blackout. They prevent the passage of daylight into the room. The fabric is multi-layered, opaque, creates complete protection from outside light. Suitable for bedroom, nursery, conference rooms, home theaters.
• "Day Night". The canvas consists of dense and translucent horizontal stripes.The light saturation of the room can be adjusted by shifting the transparent stripes in relation to the opaque ones.

Standard size of roller blinds

• Medium-sized fabric roller shutters are the most popular. The width of the curtains for such curtains is 600 mm, and the height is 1300-1700 mm. Blinds of standard sizes can be of different types:
• Classic. The canvas is monochromatic, performed in any shades.
• Black-out. The curtain completely shades the room.
• With drawing. Patterns, flowers, abstraction - these and other motives adorn the canvas. If desired, you can make photo printing on the canvas.
• Day Night. Adjustable shading by offsetting light and dark stripes.

In addition, the following parameters are considered the standard sizes of roller blinds for plastic windows: width 300-900 mm, length 1000-3000 mm. For windows that are too large or small, it is necessary to make custom-made roller blinds.

How to choose curtains for the size of the window

To choose the right roller shutters, you must first measure the window. To do this, you need a tape measure with centimeters, a pen and a notebook. Measurements depend on how the curtain will be attached: to / in the window opening or directly to the sash.

Width

If you plan to install a curtain on a window opening, then the width is determined simply: using a tape measure, you need to measure the distance from one edge of the window to the other. Then add 5 cm to the resulting value on the sides. This will be the required width of the curtain.

When the canvas is attached to only one sash, and not over the entire opening, the width is determined differently:

1. The width of the sash glass is measured.
2. 3 cm is added to the resulting figure.

If the frames are wide, then you can add 4 cm. Thus, the curtain will be 3 or 4 cm wider than the glass. It is important to take into account the accessories: handles and hinges. They should not interfere with the free hanging of the canvas. The curtain should not go beyond the fittings and prevent the free opening and closing of the window.

Height

The height is determined depending on the attachment point. If the window is located in the same plane with the wall, then the height of the window opening is measured and 8-10 cm is added.

But, as a rule, the length of the window sash does not need to be measured. The curtain fabric has a standard length of 160-170 cm. It can be adjusted at will.

How to take measurements

You need to measure 2 parameters: width and height. Since the height of curtains is usually standard, special attention should still be paid to the width. Measurements are taken with the window closed. To do this, you need an ordinary tape measure with a millimeter precision. Depending on the type of installation, measurements are made in different ways:

• On the opening. The desired allowance is added to the width of the window opening on both sides.
• Inside the opening. For this type of installation, the height and width of the window opening are measured with an accuracy of mm. But it is necessary to take into account the unevenness of the window opening.
• For each transom separately. Measure the width of the glass to the frame. Then add 2-3 cm on each side. If there is a handle on the sash, then add the distance to the handle to the width of the glass. Then we make an allowance of 2 cm on the other side of the curtain.

The height is measured from the top to the bottom of the sash. In this case, it is necessary to take into account the presence of glazing beads. If it is figured, rounded or beveled, then 2-5 mm is added to the measured height to overlap the glazing bead.

How to avoid mistakes

Simple rules will help you avoid measurement errors.By observing them, you can choose the perfect curtains for each window.

1. Take measurements in 2-3 places. Often the width and height of the windows differ at different points. Therefore, it is necessary to take measurements at several points, check the results and choose the most suitable value.
2. Take into account the dimensions of the roller shutters. Roller shutters are of open and closed type. The first option is cheaper, it can be adjusted in width if it was not possible to measure the width correctly. But there is a significant disadvantage - the curtains get dirty quickly. For products of a closed type, the canvas is hidden in a box and does not get dirty so quickly, although the price is higher.

   Due to the plugs and fasteners, the roller shutter width is 0.3-0.5 mm larger than the curtain width. If you do not take into account these dimensions, then the canvas will have to be cut after installation. It is also necessary to clarify the depth of the mechanism. This parameter will determine whether the sash will open normally or not.

3. Pay attention to the position of the handles for opening the sash. When open, the roll should not go beyond the handle. Otherwise, the canvas will interfere with opening and closing the window. If the curtain clings to anything during use, the structure may break. The overhanging bottom will get dirty and deform, touching the window sill.

Advantages and disadvantages

When choosing suitable roller blinds to protect windows from light, it is important to be aware of their strengths and weaknesses. The pluses include:

• Budgetary price. The cost of such devices is not too high. The cheapest option is the Mini roll system. It is small in size and does not have a cassette. Allows you to close each sash separately.
• Saving space. In small apartments curtains, tulle can "eat" most of the space. When assembled, the roller shutters are practically invisible, and when opened, they only cover the opening itself or even a separate transom.
• The choice of the degree of shading. The canvas can be made from different fabrics. They provide varying degrees of shading, from full light transmission to 100% opacity. This is very convenient for different types of premises.
• Protection of the canvas from dust and dirt. The fabric of roller shutters is usually impregnated with a dust-repellent, non-flammable or moisture-resistant compound. This makes them immune to fire, damage and pollution.
• Application in any premises. Rolled curtains are used in different types of premises: residential and non-residential. Suitable for any room in an apartment, private house or office.
• Easy maintenance. All you need is to wipe the roller shutters 2-3 times a week. To do this, you need a dry cloth or a slightly damp cleaning sponge.

The disadvantages of roller blinds include vulnerability to moisture and low temperatures. The linen cannot be washed, only dry cleaned. Among the disadvantages is the simple design, which often has to be complemented with tulle or curtains.
