A specific class of domestic sewing machine is identifiable by the short distance between the needle clamp screw and the base of the machine. This measurement dictates compatibility with presser feet and other attachments designed for this configuration. Machines of this type are commonly used for a variety of home sewing projects, from garment construction to quilting.
The standardized short shank distance allows for interchangeability of a wide range of readily available accessories. This design contributes to the versatility and ease of use of these machines, making them a popular choice for both beginners and experienced sewists. Historically, this configuration became a dominant standard, contributing to the growth and accessibility of home sewing throughout the 20th century.
