The perception of the room as a whole depends on their appearance.

Window decoration

The size of tulle and curtains directly depends on:

  1. type of curtain (Roman or drapes);
  2. length of the cornice;
  3. parameters and features of the window opening;
  4. the designer's general idea.

To avoid annoying mistakes when purchasing curtain fabric, you need to correctly calculate the size of the curtains.

If one of these factors is not taken into account, it will be difficult to correctly calculate the sides and area of ​​the product. Accordingly, the aesthetic part of the enterprise is at risk.

If the tulle is too short, it will not be able to perform its intended function – to diffuse sunlight and complement the room’s design. This is especially true for the living room, because the flaw is striking and spoils the overall impression and mood.

The choice of curtain rod depends on the design of the room, the size of the surface to be decorated, the style of the curtains, the weight and texture of the fabric, and the method of its attachment, to the wall or ceiling.

If the curtains in the bedroom are not long enough, they will not be able to fully darken the space. And excessively large dimensions look untidy, and it is also unsafe. They are inconvenient to handle in everyday life, and they quickly get dirty.

How to choose a curtain rod according to the window size

Curtain width, cornice width - usually different numbers, because exactly the same fabric sizes are selected for roller blinds, while the rest assume an allowance for drapery. But before deciding on curtains, you need to know how to calculate the cornice length.

how to measure curtain rod
If the standard size of the cornice does not match the length of your opening measurement, you can always cut it.

They are selected for curtains in the following way.

  1. To the horizontal value of the window opening you need to add 15 cm on each side. This means that in total you will need to add 30-40 centimeters.
  2. But there are exceptions that need to be taken into account: the material's ability to drape, and how harmoniously the window size fits into the decor. It is necessary to increase it to 50-60 cm if it is too small and it is important to visually enlarge it. And if the curtains are not prone to folds, are heavy, then you need to think about how to conveniently move them to the side, allowing light to better penetrate the room.
  3. If you have a large window, you can choose a shorter length for the increase than usual, but it is recommended not to make it shorter than ten cm at each end.

Wall cornices 3 m long must have at least 3 support points: 2 on the sides, one in the middle.

A mistaken opinion of beginners is to select the length of the cornice close to the window opening, in which case there will be a gap. And the curtains then do not fulfill their intended purpose: limiting the amount of sunlight inside the room and interior design. After all, this will not have external attractiveness, and there will also be gaps, which they usually try to get rid of.

Standard parameters were derived from the ergonomics of typical rooms in which windows and walls are practically the same size.

Choosing the length of the curtain rod for roller blinds

The type of roller or Roman blinds usually involves hanging the fabric directly next to the glass. It should close completely without gaps, but also remain functional. That is, how to choose the right curtain rod and calculate its length.

Calculating the dimensions of a curtain rod for a roller blind is easy, just measure the width of the window.
  1. The size of the cornice is thought out so that the curtain can completely cover the window.
  2. But it is important to take into account that this does not interfere with opening and does not damage the slopes.
  3. Usually the ideal dimensions correspond to the formula length plus 10-15 cm.

Roller blind holders can be purchased ready-made or ordered from a workshop.

Please note: if Roman blinds are attached to a window opening, then this is done according to the rules for curtains.

How to calculate the width of a curtain by the cornice

How to choose the size of the curtain for the window is a question that arises after choosing the cornice itself. The basic values ​​of the centimeters of the canvas are the minimum width and length without additional nuances. Based on these figures, each housewife calculates whether it is necessary to add additional segments, in what quantity.

Calculation of curtains by the width of the cornice
A properly installed curtain rod should extend from each side of the window opening by 20-25 centimeters.

Often, the length of the curtain rod is a relative value, because much depends on the design, which does not always fit the full use of the fastening pipe in the standard position. In the bedroom, the curtain fastening is often made from wall to wall, in other rooms the additional distance is less. Therefore, the best option is to focus on the curtain model, the number of layers, the type of fastening.

This installation allows you to freely move the curtains to provide sufficient lighting for the room.

What is the best way to take basic measurements?

  1. The height is measured using a centimeter or tape measure from the hanging point to the bottom point (usually 3 cm from the floor).
  2. The width is measured with the same devices, only the reference points are the first and last fastenings (they are often hooked on the very corners of the product).

If desired, a window that is too narrow can be visually expanded.

We are refining the width parameters to perfection

The width of the curtain is not only the distance from the first to the last hook, but also the consideration of the drapery that the owner wants to make. The splendor and volume of the folds also depends on the area and furnishings of the room. If the window is in a spacious room, and there is no furniture close to it, then a large amount of drape will look impressive.

Less noticeable folds fit better into modest footage.

The most accurate measurements are obtained by using a metal tape measure rather than a traditional measuring tape.

This means that the following must be taken into account.

  1. A rather large bedroom or living room often has small windows, so a lot of drapery is inappropriate there. The same applies to the doorway.
  2. If the window design is characterized by two layers, then the upper panel should be 15 cm longer to create a more effective result.
  3. If the room is not very spacious, but not too modest, then you can use standards that are calculated from the length of the cornice. Its length (if two or three sashes) is usually multiplied by a factor of one and a half. And long curtain fastenings from two to four meters are multiplied by the values ​​​​two and three, respectively.
  4. If the dimensions of the window and the room are not proportional, not standardized, then you can start from the type of material. The values ​​of curtain lengths are usually multiplied by one whole and seven tenths, and veils, printed organza - by two. If the latter fabric is without a pattern, then you can safely multiply it by three.

The use of ceiling cornices allows you to beautifully decorate windows, as well as separate part of the room with a curtain.

Important: the lambrequin is not counted in the same way as the curtains, their length is equal to the length of the fastening pipe.

Example of calculating a curtain if the length of the cornice is 3 or 4 meters

When curtains are 4 meters wide or even more, the designer bears considerable responsibility. After all, large windows become the central part of the interior, it is important to design them correctly, taking into account the rules and wishes of the owner. Therefore, for such cases, the path of self-sewing is usually chosen.

Everyone decides for themselves what length a wall or ceiling curtain holder should be.

To do this, you first need to measure a 3 or 4 meter curtain rod to understand what the exact base figure will be, which will then need to be multiplied by the drape coefficient (DC).

Correctly selected dimensions of the cornice will not only create a cozy atmosphere, but also facilitate various manipulations with curtains.

Instructions:

  1. We determine how many parts will need to be sewn.
  2. Then cut them out taking into account the pattern and seam allowances.
  3. In some cases, when the fabric has a large proportion of natural composition, it is necessary to allow a centimeter or two for the fabric to shrink after washing and ironing.

By choosing the right size of the cornice and installing it at a certain height, you can visually expand or narrow the room, increase or decrease (again visually) the height of the ceiling.

Advice. Often after sewing long original curtains (especially with a pattern that was selected) there are fabric remnants. It is good to make garters or pillowcases for decorative pillows from them. This will add harmony to the interior and will look stylish.

Calculating the width of a curtain with a long cornice

Curtains with a side ratio of one to three or more are usually more suitable for heavy drapery. Therefore, it makes sense to use its coefficient - KD. For example, for this we will take a curtain fabric, the cornice is three meters, with it KD = two and a half. So, we multiply these numbers and get a curtain width of seven and a half meters.

curtains on a wide cornice
If you want the cornice to be invisible, choose an aluminum profile cornice or a plastic rail (cornice).

But the fabric cut in width will have to be made longer by at least two or three centimeters for processed seams and shrinkage. And if the edges are with bias binding or other decorative elements, then such additions are not necessary. The same applies to artificial materials that do not shrink.

Cornices are most often installed in one, two or three rows.

Examples of correct calculation and design of windows

If the owner has a standard double-wing window, usually one meter and forty centimeters wide, then the cornice is selected for it + 15 cm on each side. This means that the sum of the length of the window opening and the indent will be equal to 1.70 m. Considering that such windows are most often in the kitchen, the fabric will not be heavy, there is no point in draping it heavily, so the coefficient can be equal to two or slightly less.

Calculation of curtains for the kitchen
By installing a cornice right under the ceiling, you can visually increase the height of the room.

As a result, we multiply the length of the cornice by a factor of two, we get 3.40 m of the curtain itself. And for cutting, we need to add centimeters for processing and shrinkage. It turns out that we need to cut three and a half meters of width for the curtain.

If the ceilings are high enough, the cornice can be installed slightly above the window.

Conclusion

The width of the curtains and cornice is an important component when calculating the sewing and installation of the product, because it should look presentable and allow the interior to look complete. If the window is large, it automatically becomes the center of attention, so it is important to make it perfect, so designers are often invited to implement the enterprise. They know how to take into account the nuances of the material, furnishings and dimensions of the room, as well as accurately calculate the drapery coefficients of the material.
