On the material, size, installation, hanging method of curtains, it is enough to see this article

Curtains are a skill to create a fun roman blind cord, a manifestation of the owner’s taste, and an increasingly indispensable space decoration in a society that pays more and more attention to privacy. The morning opens the bright mood of the day with the flying veil, and the night ends the disturbance of the day with the closed train. Like a heart door, it opens and closes as it pleases. In this way, how to agree will be a decision-making problem.

1, wide fabric (fixed height)


The first is the high fabric, which is commonly referred to as wide fabric. Such fabric usually its fixed height is 2.8m height, the width is infinite wide. The amount of fabric used is the actual width multiplied by the fold. In general, the more multiples are 2.5 folds, and the slightly less multiples are 1.5-2 folds.

Algorithm of roman blind cord fabric:

Then such fabrics are suitable for some relatively low height Spaces, and the window height is limited to about 2.5 meters. It should be noted that the wide fabric will have a step of assembly, and the edge of 10-20 cm is generally collected to make curtains.


The track is equal to its actual width, such as the style of the curtain its outer frame straight width is 2 meters, then the track of the curtain also needs 2 meters.


Under normal circumstances, the bottom edge of the lead refers to the bottom of the curtain to enhance the curtain of the role of a lead, such lead is mostly used in some relatively light fabrics.

Like the yarn type of slightly weaker fabric, because it is relatively thin, so the bottom edge needs to fall lead. The bottom edge is also a multiple of the actual width multiplied by the fold, resulting in the desired number of meters of lead.

2, Narrow fabric (fixed width)

The second is narrow fabric, narrow fabric is generally fixed width. According to each manufacturer, the number of meters of narrow fabric will also be different. Some are 1.3m, some are 1.4m, usually 1.5m. The amount of fabric used is a little more complicated.

It’s the actual width times the fold. Let’s say you have two meters of window width, times twice the fold, that’s four. Then divide four by the width of the door width (that is, the width of the 1.4-meter or 1.5-meter fabric mentioned above). Sometimes the result of this algorithm will not be an integer, such as the result of the calculation is two or a few points.

In this case, a few points usually counts as two, and two points usually counts as three. This place does not take the way of rounding, regardless of the number behind the decimal point is usually its value is rounded up. For example 2.9 harvest 3,3.9 harvest 4 and so on.


The actual height is explained by an example, such as the window height of 5 meters, and the length of a pull side in the case of 5 meters is also added, usually 20-30 centimeters, a total of 5.3 meters.

Then 5.3 times the value just calculated above, such as 2 or 3, the result is the final amount of fabric needed in meters. And the orbitals are equal to the actual width of the line.


The lead on the bottom edge is also multiplied by the fold multiple according to the actual width value. For example, there is a width of two meters that needs to be made of curtains, then make twice the fold of the curtain 2 times 2 can be.


Here you can not use the amount of fabric algorithm, different door width can use different algorithms to calculate.
