How to Adjust Tension on Singer Sewing Machine

When it comes to sewing machines, the Singer sewing machine is a popular choice for sewers of all skill levels. They are one of the oldest and most well-known brands on the market. Singer also has a reputation for producing durable machines that can stand up to years of use, which makes them an excellent choice.

Knowing how to adjust the tension on your Singer sewing machine can be a real lifesaver. For instance, if you are working with very heavy fabric and find that it is bunching up in places while you are sewing, then you should try loosening the tension.

Likewise, if your seams are puckering or not lying flat against one another when pressed, then your tension may need tightening.

Guide on Adjusting the Tension on Singer Sewing Machine

1. Find the tension regulating dial, The tension regulating dial is usually located on one of the legs of the machine. You will want to turn this knob in either direction based on your needs, tighter for if seams are not lying flat against one another and looser for when you are working with heavier fabrics that may be bunching up around the needle.

2. Loosen the tension by turning the adjusting knob to the left. This will allow the bobbin hook to move as it winds thread from the bobbin so that it can curl under and catch more of it as you sew.

This adjustment will also make your stitches wider for a more relaxed look.

3. Try stitching a test seam with a scrap of fabric to see how it looks before sewing a larger piece of fabric or project, then adjust accordingly.

3. Tighten the tension by turning the knob to the right until you feel resistance on your hand, which will make your stitches tighter and less likely to fray or come undone after many washes.

4. Try stitching another test seam to see how this adjustment looks, then adjust accordingly.

5. Test your tension until it’s perfect. Continue sewing test patches until you’ve achieved equal stitches on both sides and the tension is correct.

Once you’re satisfied with the tension, finish setting up your machine, and begin working on your project!

Common Questions About Adjusting Tension on Singer

What should the tension be set at on a Singer sewing machine?

The tension on a Singer sewing machine should be set somewhere between 2 and 3.

How do I fix the upper tension on my sewing machine?

To fix the upper tension on your sewing machine, please follow these steps:

1) Thread Needle – Make sure you have threaded the needle correctly. On many machines, there is a threading diagram right on the machine that shows how to thread the needle.

2) Check Thread Tension – If you think your thread is too loose or tight, go ahead and put it somewhere in between 2-3.

  • Slowly turn the knob (which could be labeled “TENSION” or located under the plate of your machine) and watch how the thread moves.
  • When the tension is correct, you should see a “V” shape between the top and bottom thread. This means that your tension was adjusted correctly.

3) Check Upper Thread Tension – To check your upper thread tension, throw some scrap fabric under the presser foot. If the thread is too loose, you will see your top thread (the bobbin thread) on top of your fabric. If the thread is too tight, you will not be able to pull it through the machine or out from underneath your presser foot.
