Proper Bobbin Use

There are many different sizes, styles, and types of sewing machine bobbins, and knowing which one to use can be difficult. ZJ Humbach shows several of the different types available on the market today, explaining the difference between them and which machines they are used with.

Bobbin Sizes, Types, and Styles

To help you better understand different bobbin sizes, ZJ begins by showing some of the most common sizes and styles of bobbins available and explains some of their main differences. Some of these differences are easily recognizable. For example, some sewing machine bobbins are metal while others are plastic. Other recognizable differences between some of the bobbins are the size, with some being much larger than others. ZJ explains that larger sewing machine bobbin sizes are typically for long arm quilting machines or even some embroidery machines.

While some bobbins are easy to tell apart in terms of size, some may only differ slightly by how wide or tall they are. When bobbin size is not easily discernible, you will need to know which letter or number the bobbin is labeled. Some of the more common bobbins are “L,” “M,” and “J.” If you are unsure what size and type of bobbin you need for your machine, it is best to always consult your machine manual. Using the wrong size of sewing machine bobbin in your machine can not only cause issues like skipped stitches and poor stitch quality, but it can also damage your machine.

Also, even though you might be using the correct size and style of bobbin, some machines prefer metal bobbins while others prefer plastic. It is always best to use the type of bobbin that came with your machine or the one that is listed in your manual. Once you learn about the different sizes, types and styles of sewing machine bobbins, learn about proper bobbin storage and transfer.
