Number of stitches
The number of stitches that a sewing machine can sew. The larger this number, the more extensive the capabilities of this model, the wider the choice the user has; however, it wouldn’t hurt to clarify the specific range of supported stitches separately.
The fewest options - mostly up to 25 - are provided in electromechanical machines, as well as specialized devices such as overlockers and carpet lockers (see “Type”). In computer-controlled devices, the number of lines can be in the dozens, and some also allow you to download additional options from the computer.
Max. presser foot height
Distance from the working surface to the foot in the uppermost position. Must be taken into account when working with thick fabrics.
Sewing speed
The maximum sewing speed provided by the sewing machine. In the vast majority of models, this parameter can be adjusted, so if necessary, you can sew at a lower speed.
The more stitches a machine makes per minute, the higher its productivity, the better suited it is for large volumes of work. At the same time, it is worth considering that high speed has a corresponding impact on price and energy consumption, and it is not always required. Detailed recommendations on choosing the optimal speed for certain types of work can be found in special sources.
Led lighting
Built-in lighting system that illuminates the working table of the machine, which is made on LEDs. In addition to bright illumination of the work area,
LED-backlit sewing machines also have lower energy consumption compared to classic lamps.
