What Curtain Length to Buy: Measuring the Curtain Length



When you buy a new curtain for your home, it is necessary to measure the curtain before ordering. For this, first of all, you need to learn how long the curtain should be according to the area you will use and the type of curtain and then measure it. After you decided what curtain length to buy, you can start measuring the curtain length. Actually measuring the curtain length is not as hard as it sounds. Let’s check it together.



You can get the width of the curtain according to the size you want. If you want the height to touch the ground, you should give 3 cm less than the measurement. For the background curtain, you must first measure the height of the glass, then order 3 cm less than that number. If you want to accumulate heavily on the ground, you should measure it to the ground and add 15 cm more. If you want to use the curtain for decor, you should try not to measure it transversely. It is recommended that you take the size of the roller blind by distributing it equally on both sides of the window frame by moving a total of 40 cm. For the double-breasted curtain, you must first move it at least 25-50 cm from the right and then from the left. For the height, take the measure to the ground and order it as it is without overflowing.

How Long Should The Curtain Length Be?


I will offer you great ideas with extensive narrations about curtain length. I have explained the points you need to pay attention to in our dozens of articles on the selection of curtains specific to each place. In the following paragraphs, I will give information about how the curtain length will be. First of all, curtain selection is a matter of your own taste. You can get ideas about color and model from the image galleries that have been published on the internet. Today, classical curtains make the space completely different thanks to their deep vertical curves. It takes the first step of different decorations with its delicate and luxurious appearance. You can change the atmosphere of your home with different types of curtains. So what can come to mind when it comes to curtain length? Let’s detail this work a little more.



Curtains are a decoration item that adapts to any space and is a must for a home. We have presented examples of different types and models related to curtain length in our topic for you to examine. First of all, you should decide before answering this question, that the size of the curtain adapts to the furniture in the room. Our first advice to you is that if your room is large, there is no harm in touching the ground. However, if your room is narrow or small, touching the ground may be a problem in terms of decoration. In this title, we would like to remind you that you can find curtains of all types and models. The atmosphere of the houses furnished according to your own taste becomes better. Nowadays, when we are in the middle of 2020, different types of curtain models appear. First of all, we want to talk about standard curtain sizes. The word standard is used in the general meaning.

Curtain length is a term calculated from the ceiling and floor height. The standard height in the world is between 2.10 and 2.30. As can be understood from here, the curtain lengths valid for standard houses are between 2.10 and 2.30. But we meet with many places that go beyond these standards. In this, curtains must be purchased by measuring. So, speaking of the standard, what is the standard size of the tulle curtain? In this title, we explained the standard curtains as 2.10 – 2.30. The standard of the tulle curtain is the same as the normal curtain. So we can say that the standard tulle size is 2.10 – 2.30. But the curtains over the heater are a little different. Let us point out that the tulle curtain can be up to the front of the glass, as well as this aspect ratio may decrease. So how long should the background be? The aspect ratio of background curtains is generally in the same proportion as the normal curtain. When examining the background curtains we have prepared for you below, you will clearly understand what we mean.

How to Measure Curtain Lenght


The dimensioning shape taken in all curtain options except the Breeze curtain is dimensioning from the ceiling. Fabric or tulle curtain sizes are mounted to the ceiling with the help of curtain carrier systems such as rail with cornice circulation. Therefore, first of all, we need to explain how to dimension the curtain carrier systems.

  • Curtain Carrier Systems: Mechanized or manual systems that are used to carry and operate curtains such as tulle, fabric, folded, sunshade on the ceiling. Curtain carrier system options are as follows.
  • Cornice: Curtain carrier rails made of aluminum or PVC that allow curtains with single, double, and triple options to move to the right or left.
  • Circulation Rail: There are only singles. It is one of the aluminum curtain carrier rails with a rope control system. Thanks to the rope control, you can operate your curtain to the right or left or open in the middle.
  • Folding Curtain Mechanism: It is a curtain carrier system that enables the folding curtains to be opened and closed up and down with the help of chains, ropes, and gear.
  • Panel Curtain Mechanism: It is a curtain carrier system consisting of moving panels with an average width of 60 cm, which allows the panels to be opened to the right, left, and middle optionally thanks to the rope control. Panels do not rotate around their own axis. It should only be preferred on wide glass facades up to the floor.


As in all dimensions, the ceiling should be looked at first and it should be determined whether there is a curtain carrier system. (The material is made of materials such as plaster, styrofoam, polyurethane, and wood, and it is an application made of window width or wall to wall on the ceiling to hide curtain carrier systems or rails.) If there is a curtain carrier system, the cornice size should be taken in the same widths based on the curtain dimensions. If there are no curtain carrier systems, it must be removed by moving 20 -30 cm from the width of the window. For example, if the window width of a facade without a curtain is 250 cm, the cornice width maybe 300 cm on average. Cornice selection should be made according to the curtain types to be used. Standard cornice options are available up to four rails, including a single rail. If more curtains are to be installed, then the option can be increased by using two triple cornice rails. For example, if a background curtain, tulle curtain, and sunshade curtain will be used on a facade, a three-rail cornice is sufficient for this application.

As in all dimensions, the ceiling should be checked first and it should be determined whether there is a curtain holder. If there is a curtain holder, the circumferential rail size should be taken in the same widths based on the curtain dimensions. If there is no curtain holder, it must be removed by moving 30 -40 cm from the width of the window. For example, if the window width is 250 cm on a facade without a curtain, the width of the railed rail can be 300 cm on average. When ordering the rails with circulation, attention should be paid to which side the rope direction to control the curtain will be and whether it will open in the middle. Its standard color is white static paint over aluminum.

How to Measure the Folding Curtain and Its Mechanism


In this dimensioning, it is not very important whether there is a curtain holder on the ceiling. The reason is that since the front of the mechanism is covered with fabric, it does not exhibit an appearance that will spoil the aesthetics. Dimensions vary depending on the width of the fabric when measuring the folding curtain mechanism. Fabric widths vary according to some brands and fabric types. While standard fabric widths are 140 cm, some brands (Bondrap) are 280 cm wide. Likewise, tulle widths vary between 280 cm and 300 cm. In this case, the mechanism should be measured by paying attention to the width and type of the fabric to be used during dimensioning.



For example, when we consider that your window width is 300 cm, the mechanism dimensioning options to be taken in this window is briefly as follows. If you want to use a standard fabric and make the curtain in one piece, this option is not suitable because the width of the fabric is limited to 140 cm. Instead, 280 cm wide fabric (Bondrap) of tulle should be used. So, if you want to make a single piece of the folded curtain in a 300 cm wide window, how is it possible to use 280 cm wide fabric or tulle? Namely, 280 cm wide fabrics or tulles are used in width, patterns, or weavings on this fabric, and tulle is processed according to this logic in curtain fabrics. Therefore, 350 cm fabric or tulle ball, including the seam allowance, can be easily sewn and a folded curtain in the desired size can be sewn and adapted on this mechanism.

The other option is, in a window with a width of 300 cm, the opening sash widths vary between 80 and 90 cm according to the standards, and it probably consists of a total of three compartments of this size, one on the left, one on the right and the fixed sash in the middle. Wing widths are 90 cm 120 cm 90 cm. In this case, 100 cm mechanism size is taken for the 90 cm dimension, 119 cm mechanism size is taken for the fixed middle wing of 120 cm, and the mechanism size is also 100 cm wide for the other opening wing on the right. In this way, we have extended 10 cm from the edges and left a 0.5 cm gap in order to prevent the curtains from rubbing with each other. When measuring the height/length, the size between the ceiling and the window sill should be taken. Let’s assume that this size is 180 cm, in this case, a share must be added to pass the 10 cm sill in the paint. However, if there is no required share, you can stay on the windowsill.



In the windows up to the floor, the length measurement should be taken to the floor. If the overflow areas from the window edges are not sufficient, then the width of the mechanism should be measured by moving the window to the appropriate point. As a result, standard 140 cm wide fabrics can be easily used in dimensioning such a mechanism. It is a much better choice not to exceed 140 cm in the width of the folded curtains. Making curtains according to window sash widths increases aesthetics and functionality. As we explained above, folding curtain mechanisms are a system that opens and closes up and down with the help of chains. In this case, what should the direction of the chains be? When determining the chain directions, you should prefer the hinge direction on the opening wings, so that your chains do not get stuck and destroyed when the window is opened and closed. In fixed window panes, it is okay to choose the direction that is easiest to use.

Considering the 90 cm 120 cm 90 cm window above, the chain directions of the mechanism should be left, right, and right. The most important point to be considered in the size of the folded curtain is the collective share between the ceiling and the sash. In standard houses, the share between the opening wing and the ceiling is generally between 40 cm and 60 cm. The total share of folding curtains when they are collected upwards is min. It is 25 cm. Therefore, if the folding curtain is erected in the houses where the share between the wing and the ceiling is 25 cm below, the opening wings cannot fulfill their functions fully. The curtains stay under the opening wings and the wings cannot be opened by being attached to the curtains. This situation causes both the wings not to open and the sewn curtain to be deformed due to the snagging of the opening wings.

Folded and Panel Curtain Measuring


Let’s assume that the fabric length calculation according to the width of 140 cm is 100 cm and the length 180 cm as we explained in the above measure. The seam allowance to be added to such a measure is 40 cm from the length. (According to the rear rod folded curtain) in this case, the amount of fabric required for this curtain is 220 cm. The necessary fabrics for the bars of the folded curtain will be obtained from the edge pieces. Calculation of fabric length according to 280 cm width. Let us assume that our folded curtain dimensions are one piece and 300 cm in width and 180 cm in length as in the above dimension. In this case, when we add 50 cm to the total size for edge seam allowances, we will reach the required size for sewing the curtain. A total of 350 cm of fabric is enough for this curtain to be sewn. The seam allowance of 40 cm, on which dye should be added, will be sufficient since the fabric is used in width.



Panel widths on the panel curtain mechanism vary between 50 cm and 60 cm. It can be produced under or above these dimensions upon request. However, the most suitable and aesthetic dimensions are the sizes between 50-60 cm. The following should be considered while measuring the panel curtain and mechanism. In this dimensioning, as in the folded curtain, it is not very important whether there is a curtain or not, because the fabric is sewn to cover the panels. As we mentioned above in panel curtain size, panel widths generally vary between 50-60 cm. If space is available at the edges of the windows, it is useful to leave a gap between 50-60 cm for each side. Because the panels do not cover the windows either when they are opened from the middle or when they are gathered at the edges, and they stay in this area reserved for them. In places where there is not enough width, instead of opening in the middle, it should be gathered on the right or left, considering the ease of use. Another issue to be considered is that if there are different windows in the same room or area, care should be taken to ensure that the panels are very close to each other in different curtains at the width of the mechanism. Otherwise, the panel widths of the curtain in one window might be 50 cm due to the measurement, while the panel width of the curtain in the other window might be 70 cm. In this case, you will have curtains of different panel widths in the same space.

There is no problem in terms of functionality, but they do not look very aesthetically pleasing. The panel widths of curtains in different windows should not be less than 10 cm or more than 10 cm from each other. Another issue to be considered in panel curtains is that the windows should be glass to the floor and the window widths should be more. Panel curtains can be sewn or produced in half. However, when they are up to the ground, they look much more aesthetic than half height. In addition, they are more aesthetic on wide glass facades than narrow glass facades. In line with this information, when taking the panel curtain size, if there is enough space for the width, it should be moved 50-60 cm from the window edges and 2-3 cm from the ceiling for the height. If the width of 50-60 cm from the edges is not enough, the maximum width should be taken. For example, suppose we have a 200 cm wide window, let’s assume that our room ceiling height is 270 cm. If the panel curtain and mechanism size to be taken are to open from the middle, the width should be 300 cm and height 267 cm. If the curtain is to be gathered on the right or left, the width should be 250 cm and the height should be 267 cm. Again, the most suitable area of ​​use should be selected for the direction.



According to the fabric width of 140 cm: Assume that the panel curtain width is 300 cm and the height/length is 270 cm. In this case, since the panel widths will be 60 cm and 5 pieces, 2 pieces of fabric with panel width including seam allowance are obtained from 140 cm fabric width. For 5 panels, 3 most fabrics are needed. Since the length of our curtain is 270 cm, a fabric seam allowance is added at 30 cm and fabric of 300 cm is required. In this case, when we multiply the length and width, it is 9 meters. We reach the fabric meter. The required fabric length for this curtain is 9 meters. If the lining or curtain is to be sewn from the same fabric, the lining or the same fabric is used as much as the length of the curtain.

According to 280 cm fabric width: Assume that the panel curtain width is 300 cm and the height/length is 270 cm. In this case, since the panel widths will be 60 cm and 5 pieces, a 10 cm seam allowance is added to 60 cm panels and 350 cm of fabric is needed when multiplied by 5 panels. Since the length of our curtain is 270 cm, there is no problem since the fabric will be used in width. If the lining or curtain is to be sewn from the same fabric, the lining or the same fabric is used as much as the length of the curtain.

Measuring Curtain Length Over Cornice


The tulle size width should be the same as the cornice width. The height should be 2-3 cm shorter than the height between the ceiling and the floor. 100 cm wide 250 cm tulle, whose calculations were taken on the cornice, should be used. The use of tulle on cornices should be 1 to 2.5 or 3 on average. Optionally, it can be above or below these rates. For example, if we assume that the cornice width is 200 cm in a 200 cm wide / 260 cm high/tall window, an average of 500 cm tulle should be used. The tulle size should be 257 cm. The user should decide whether the tulle will be one or two pieces according to the ease of use. Tulles are also used in width – length, the pattern or print is processed according to this logic.

Sunshade size width should be the same as the cornice width. The height should be 2-3 cm shorter than the height between the ceiling and the floor. A 100 cm wide 150 cm sunshade, whose calculations were taken on the cornice, should be used. The use of sunshades on cornices should be 1 to 1.5 or 2 on average. Optionally, it can be above or below these rates. For example, if we assume that the cornice width is 200 cm in a window with a width of 200 cm/width of 260 cm/height, an average of 300 cm sunshade should be used. Sunshade size should be 257 cm. The user should decide whether the sunshade will be one or two pieces according to the ease of use. The sunshades are used in width length, they do not have patterns and prints, their standard colors are beige, champagne, and white.



Fabric curtains are sewn using fabric groups with many options such as silk, viscose, linen, and chenille. Their purpose of the use is to exhibit functionality and aesthetics together. Many designs can be made, either alone or with the add-on mechanism, depending on the limits of thought. Fabric widths vary between ~ 140 – 300 cm. The recommendations of fabric manufacturers are generally dry cleaning, but depending on the type of fabric, it can be cleaned with gentle washing at 30 degrees. The calculation and dimensioning of the fabric curtain over the cornice with a width of 140 cm should be multiplied by making the necessary additions to 1-meter width and 1 width fabric curtain length depending on the width of the cornice. For example; When calculating a fabric curtain for a window with a width of 230cm and a height/length of 255, the 3-width fabric will be used at 230 cm. The reason for this is that since one width of fabric will be used for each meter, one width of the fabric must be used for the remaining 30 cm. (If we make the same proportion for 30 cm, in this case, the remaining part of the fabric width will not be used anywhere, so it will remain as waste. It is better to feed it to the measure instead.)

As a result, when the 3 widths are multiplied by the fabric length, the total length required for this curtain dimension is reached. 3 width * (255 cm + 30 cm curtain seam allowance = 285 cm.) = 8.55 mt. fabric. 8,55 mt. fabric * unit price ($ 30) = $ 256 Fabric cost. In this case, if the size is the width of the cornice, that is 230cm length/height, it should be 2-3 cm shorter than the size between the floor and the ceiling, that is, the height should be 253 cm. The most important detail that should be known in 140 cm fabrics is that the seams will be visible when the curtains are closed since these widths will be sewn together to reach the required width.



The user should decide whether the fabric will be one or two pieces according to the ease of use. Depending on the width of the cornice, 1.5 meters of fabric with a width of 1 meter should be used for the calculation and dimensioning of the fabric curtain over the cornice (Bondrap) with a width of 280 cm. For example; When calculating the fabric curtain with a width of 300cm and a height/length of 255 windows; 4.5 meters of fabric will be used in 300 cm. 4.5 mt. fabric * unit price ($ 60) = $ 270 Fabric cost. If the dimension is the width of the cornice, that is, 300cm length/height, it should be 2-3 cm shorter than the size between the floor and the ceiling, that is, the height should be 253 cm.

The user should decide whether the fabric will be one or two pieces according to the ease of use. When 280 cm fabrics are compared with 140 cm wide fabrics; Since the width of 280 cm wide fabrics are used as the length, the length measurement is not taken into consideration in the calculations, as in the fabrics with 140 cm width. For fabrics with a width of 280 cm, max height/length can be 270 cm. (The fabric widths are used in length and if the fabric is patterned, as standard, the patterns are placed on the fabric according to this logic.)

Length of Background Curtains


First of all, unfortunately, there is no standard size in the world, but if you make a generalization, it is between 250-260 cm.
This size varies from house to house. The size of the background curtain can be calculated by the following 3 ways.

  • Taking Equal Measure With Your Tulle Curtain

As we know, the length of the Tulle Curtain is measured from the cornice to the bottom, and it is realized by purchasing a certain amount (depending on how high you want it to be from the ground) and purchasing to that extent. Background curtains can be taken in the same way and stand equally.



  • Taking a Longer Length Than Tulle Curtain

We can choose the length of the background curtain longer than the tulle curtain and touch on the floor. Especially in recent years, it can be ensured that the background curtain length is long and touch on the ground in order to have more fabric and to show a more draped stance. For this measure, it will be sufficient to measure from the cornice to the bottom and add 15-20 cm to the resulting measure.

  • Taking Equal Length With the Heater

Although it is very rare, it is a preferred condition. It is an option that we do not recommend. If the background curtain is a long and heavy fabric, it will show itself and look stylish. The size of this can be purchased from the cornice to the heater and declaring an incomplete size of around 2 cm.
