The first is the fabric with fixed height, which is usually called wide fabric. This kind of fabric is usually 2.8 meters high and infinite in width. The quantity of this fabric is the actual width multiplied by the fold. Generally speaking, more multiples are 2.5 folds, and less multiples are 1.5-2 folds. Then this kind of fabric is suitable for some relatively low high-rise spaces, and the height of the window is limited to about 2 meters. It should be noted that the fabric will have an edge-closing step, and generally the edge of 10-20 cm will be closed to make curtains.

The track is equal to its actual width. For example, if the curtain style has a linear width of 2 meters, then the track of this curtain also needs 2 meters. Under normal circumstances, the bottom lead drop refers to the lead strip that plays a role in enhancing the curtain drop at the bottom of the curtain. Most of these lead strips are used in some lighter fabrics. Like a yarn fabric with a slightly weak drape, because it is lighter, it is necessary to reduce lead at the bottom. The lead pendant at the bottom is also the actual width multiplied by the fold, and the result is equal to the number of meters required for the lead pendant. 2. Narrow-width fabric (fixed width) The second type is narrow-width fabric, usually fixed width. According to different manufacturers, the meters of narrow fabrics will be different. Some are 1 m 3, some are 1 m 4, usually 1 m 5. The amount of this fabric will be a little more complicated. It is the actual width times the fold. For example, a two-meter wide window, multiplied by twice the folding, is four. Then divide the width by four (that is, the width of the cloth of one meter four or one meter five mentioned above). Sometimes the result of this algorithm is not an integer, such as the calculated result is two points or one point. In this case, one point generally counts as two points, and two points generally counts as three points. There is no rounding method in this place. No matter what the number after the decimal point is, it is generally rounded. For example, 2.9 Harvest 3, 3.9 Harvest 4 and so on. Take the actual height as an example to illustrate. For example, if the window is 5 meters high, the length of the hem should be added, generally 20-30 cm, and a * * * is 5.3 meters.
