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
It is the distance from the work surface to the presser foot in the highest position. It 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 that, if necessary, you can sew at a lower speed.
The more stitches per minute the machine makes, the higher its productivity, and the better it is suitable for large volumes of work. At the same time, note that high speed has a corresponding effect on price and power 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
A built-in lighting system that illuminates the working table of the machine, which is made of LEDs. In addition to the bright illumination of the work area,
LED-light sewing machines also have lower energy consumption compared to classic lamps.
