Stitch density determines how close individual rows of stitches are to each other when filling an area in embroidery. It is typically expressed in millimeters and represents the distance between stitching lines. A lower value, for example, 0.4 mm, means that the stitches are closer together, creating dense and full fabric coverage. Conversely, a higher value, for example, 0.7 mm, means larger gaps between stitches, making the embroidery lighter, sparser, and allowing the underlying fabric to show through slightly. This parameter is primarily used for so-called fill stitches and satin stitches, which serve to cover larger or smaller continuous areas. The correct adjustment of stitch density affects the final appearance, the stiffness of the embroidery, and thread consumption.
