Troubleshooting Guide: Why Does My Thread Keep Breaking My Sewing Machine?

Have you ever found yourself frustrated as your thread continuously breaks while sewing on your beloved machine? Don’t fret! We understand the annoyance and aim to assist you in troubleshooting this all too common sewing dilemma. In this article, we’ll explore the various reasons why your thread might keep breaking on your sewing machine and provide effective solutions to help you continue your stitching endeavors seamlessly.

Incorrect Thread Tension

One of the primary culprits behind thread breakage on a sewing machine is incorrect tension settings. Improper tension can lead to excessive strain on the thread, resulting in breakage. Let’s dive into some possible scenarios causing this issue:

1. Too Tight Thread Tension

  • Ensure that the upper thread is threaded correctly through the tension discs and other threading points specified in your machine’s manual.
  • Verify the tension dial settings. If set too high, it can cause excessive tension on the thread.
  • Test sew on a scrap fabric while making incremental adjustments to the tension dial until achieving a balanced stitch.
  • Remember, different fabrics may require different tension settings, so adjust accordingly for each project.

Highlight: “Achieving the perfect thread tension is a delicate balance that can make all the difference between sewing success and frustration.”

2. Too Loose Thread Tension

  • Inspect the thread path and confirm the upper thread is properly inserted into the thread take-up lever.
  • Ensure the bobbin is inserted correctly in the bobbin case and that the bobbin tension is appropriately adjusted.
  • Adjust the tension dial to increase the tension gradually until achieving a balanced stitch.

Poor Thread Quality or Mismatched Needle

Low-quality or old thread can be a major contributor to thread breakage. Additionally, using the wrong type or size of needle for your chosen thread can exacerbate the issue. Let’s address this concern:

1. Thread Quality

  • Opt for high-quality polyester or cotton thread from reputable brands, as they are less prone to breakage.
  • Discard old or weakened threads that may be more susceptible to snapping.
  • Pay attention to the thread weight, ensuring it is suitable for your fabric and needle combination.

2. Needle Selection

  • Use a needle appropriate for the fabric you’re sewing. Fine fabrics require fine needles, while heavier fabrics demand stronger needles.
  • Consider the needle size in relation to your thread. A needle too small for the thread can cause tension issues leading to breakage.

Incorrect Bobbin Winding or Placement

A poorly wound or incorrectly placed bobbin can wreak havoc on your sewing experience. Let’s address this issue:

1. Bobbin Winding

  • Ensure the bobbin is evenly and tightly wound.
  • Avoid overfilling the bobbin, as it can affect the tension and cause thread snags.
  • Check that the thread is wound in the correct direction specified by your sewing machine manual.

2. Bobbin Placement

  • Insert the bobbin into the bobbin case with the thread unwinding in the correct direction.
  • Confirm the bobbin case is properly seated and securely in place within your sewing machine.

Needle and Thread Mismatch

Incompatible needle and thread combinations can contribute to continuous thread breakage. Let’s explore this further:

1. Needle Type

  • Use a universal needle for general-purpose sewing. However, for specific projects or fabrics, consider specialty needles such as ballpoint or stretch needles for knits, or sharp needles for woven fabrics.
  • Choose the appropriate needle size that matches your fabric weight.

2. Thread Weight

  • Ensure the thread weight matches the capabilities of your needle. Heavy threads require stronger needles, while lightweight threads work best with finer needles.
  • Adjust the tension settings after changing the thread weight to achieve the desired stitch quality.


Embarking on sewing endeavors can be an enjoyable and fulfilling experience, but it can quickly turn frustrating when thread breakage becomes a frequent issue. By understanding the various potential causes and their solutions, you can confidently troubleshoot and overcome this obstacle. Remember to maintain proper thread tension, choose high-quality threads, match them with suitable needles, and pay careful attention to bobbin winding and placement. Armed with this knowledge, you’ll be able to bid farewell to constant thread breakage and embrace the joys of uninterrupted sewing. Happy stitching!
