How to Adjust Thread Tension on a Sewing Machine

The interactions of your needle and the shuttle hook on your sewing machine are very precise. Small changes in the tension of your thread can mean large problems. Problems with the thread tension can be caused by many things. Here is how to adjust the thread tension on a sewing machine.

Difficulty: Moderate

Instructions

Things You'll Need:

• Paper or toothpick for cleaning

1. Look to see whether the thread loops appear on the fabric back side. If this is the case, the tension on your sewing machine is too loose.

2. Check to see if your fabric is puckering on the front side when you sew. If this happens, then your tension is too tight.

3. Adjust your needle thread tension with your machine threaded and your presser foot pedal down.

4. Turn your thread tension dial as needed. If you increase the number on your tension thread dial, you will be increasing the tension on your sewing machine. If you are lowering the number on your tension thread dial, you will be decreasing the tension on your machine.

5. Clean your thread tension with a small piece of paper or a toothpick. Slide the toothpick or paper between the discs to remove any tangles of thread.

Tips & Warnings

• If you are having problems with your bobbin thread, the tension on your bobbin thread assembly may be improperly set. If this happens adjust the tension on your bobbin thread tension with a screwdriver.
• Always wear thimbles or gloves when working on adjusting your thread tension on your sewing machine.
