Seam allowance

Under the seam allowance is to be understood, the width of the distance between the actual seam and the cutting edge during the cutting of textiles. This addition varies depending on the type of fabric and the Nähvorgaben. When working for a sewing pattern for dresses are, for example, for spheres sleeves, armholes and neckline edges 1 cm to admit for all other seams 2 to 3 inches. Moreover, even the addition of a 5-7 cm to be considered for all seams.

In the men's tailoring seam allowances are generally 7.5 mm wide. At Sacco side seams and the side part on one side seam allowances are wider at the rear center seam, allowed to omit the parts possibly later (expand) to be able to. The same applies for the west side seam, the seat seam on trousers and for the crotch seam to the back of the trousers.

In pieces with lining is cut off before the last turn of the excess seam allowance to keep the edges as flat as possible. This particularly applies to articles, the inside should look just as flawless as the outside, such as bags, but also jackets, Sacco or blazer, because the inside is often visible when worn also.
