How many fabrics do you need: how to calculate the amount of fabric for curtains

Choose fabric, color and style - questionsimportant, but usually many cope with them on their own. But with the amount of fabric, a problem often arises. Especially for you, we have prepared an article on the correct calculation of the consumption of fabric. Let's imagine that our interior is already ready and all that remains is to hang the curtains. Even the cornices are already installed! Interior designer Olga Filimonova will tell you what and how to do now.

She lived in Prague for twelve years, mastered several related creative professions, such as gallery owner, graphic artist and decorator. - To calculate the classic, long curtains, we need only two measurements. The height of the future curtain from the curtain rod to the floor and the width of the curtain, when finished, is equal to the length of the curtain rod. First, let's calculate the amount of tulle. Manufacturers, as a rule, offer the width of the tulle fabric 280-300 cm, which easily fits into the standard ceiling height (no more than 3 meters). Then you just need to multiply the length of the tulle by the gathering factor. If the tulle is thin and very transparent, then I usually take the gathering factor from the calculation, which means that with a cornice length of 2 meters, the amount of tulle will be 6 meters. The effect of a gentle, airy drapery is obtained. If we take thin linen or not very transparent tulle with texture or ornament, then the drapery ratio will be much less - 1: 2.5 or even 1: 2. Curtain fabrics often have a width of 1.4, 2.8 or 3meters. In the last two cases, the amount of fabric is calculated in the same way as for tulle. Provided that the fabric is plain or the direction of the pattern goes from edge to edge. If the pattern runs along the edge or the width of the fabric is 1.4 meters, then the calculation is done differently. The fabric is picked up according to the height of the curtain, taking into account the allowances for the hem of the bottom and top, and sewn together. In this case, you need to remember about the combination of the pattern (rapport) between the canvases. The number of canvases depends on the length of the cornice and the assembly factor. If the rapport is thematic (figure, house, flower)or, for example, a large damask or monogram, then its ornament should start strictly from the top of the curtain or end at the bottom at the hem of the curtain. In this case, we need to add one more additional rapport in order to be able to shift and adjust the position of the beginning of the pattern on the finished product. To consolidate the knowledge gained, practice counting virtual curtains, taking any piece of fabric with a rapport pattern you like and count the amount of fabric for your window in the living room or bedroom.

  • If the length of the cornice is 3 meters, then we sew 4 canvases of 1.4 m.

1.4m x 4 canvases = 5.6 m

  • Let's check the assembly factor. The width of the sewn cloths (5.6 m) is divided by the length of the cornice.

5.6 m:3 m = 1.7 In fact, the gathering factor will be slightly less, since 2-3 cm from each canvas, as a rule, go to the seam seams and bend along the edge of the curtain. This factor is suitable for medium-weight fabric with an ornament. If the fabric is thinner and more plastic, then it is better to take a larger coefficient, and the calculation of the width will be as follows: 1.4 mx 5 canvases = 7 m. In this case, the coefficient = 7 m: 3 m = 2.3.

  • Now we can make a final calculation of the fabric: Determine the height of the fabric in the cut, taking into account the rapport. Let's assume that the height of the fabric from the cornice to the floor is 290 cm, taking into account the shrinkage of the fabric (3-5%), the hem of the bottom (15-20 cm) and the top of the curtains, taking into account the scallop above the curtain tape, is 290 cm + 25-30 cm = 320 cm. For example, take a large rapport - 55 cm. Cut the height of the canvas to the report - 320: 55 = 5.82, round it up and get 6 rapports. From this we see that we should take 6 rapports of a cloth of 55 cm. The total length of one canvas in the cut is 3.3 m.
  • Accordingly, the fabric consumption at an assembly factor of 1.7 will be: 4 x 3.3 m = 1 320 cm.

And with a build ratio of 2.3 it will be equal to: 5 x 3.3 m = 1,650 cm. Articles on the topic
