Embroidery Thread Weights & What Do They Mean?
Thread Weights And What Do They Mean?
Thread weight describes the thickness of embroidery thread and bobbin thread. The larger the number, the thinner the thread. The smaller the number, the thicker the thread.
1. Designs: Designs generally require a specific thread weight due to how the design is digitized. If the thread is too thick for the stitch area, there will be overlapping threads which could cause a bird’s nest under the throat plate. If the thread is too thin for the stitch area, the coverage will not be adequate.
2. Needle Size: Thread weight determines the size of the needle used in your machine. (The thicker the thread, the larger the needle hole needs to be.)a. Needle selector chart >

3. Coverage VS Detail: Heavy weight threads cover a larger area with fewer stitches. Lighter weight threads are used for detail work within designs and/or for small lettering.
4. Fiber Type: Take into consideration the type of fiber of your thread (Polyester, Rayon, Acrylic, Cotton, etc). Heavier weight threads tend to have more strength while thinner weight threads have less.
