Maintaining optimal sewing machine tension is crucial for achieving precise and beautiful seams. When tension is off, stitches may appear loose, puckered, or uneven. This blog post will provide a comprehensive guide on how to change sewing machine tension, ensuring your sewing projects turn out flawlessly.
Understanding Sewing Machine Tension
Sewing machine tension refers to the balance between the upper and lower threads. The upper thread is pulled through the needle and the lower thread from the bobbin. When tension is correctly adjusted, the threads interlock in the middle of the fabric, creating a secure and aesthetically pleasing stitch.
Signs of Incorrect Tension
Incorrect tension can manifest in various ways:
- Loose stitches: The stitches are not tight enough, leaving gaps between them.
- Puckering: The fabric puckers or gathers around the stitches.
- Breaking thread: The thread breaks frequently due to excessive tension.
- Uneven stitches: The stitches vary in length or width.
How to Change Sewing Machine Tension
1. Identify the Tension Dial
Locate the tension dial on your sewing machine. It’s usually a knob or lever with numbers or symbols indicating the tension setting.
2. Adjust the Upper Tension
- Most machines have a dial for adjusting upper tension.
- Turn the dial to a lower number to decrease tension or a higher number to increase tension.
- Start with a medium setting and adjust as needed.
3. Adjust the Bobbin Tension
- Some machines have a separate dial for bobbin tension.
- Access the bobbin case by opening the cover.
- Turn the screw or lever to adjust the tension.
- Tighten the tension slightly if the stitches are loose or loosen it if they are puckering.
4. Test the Tension
- Sew a few stitches on a scrap piece of fabric.
- Examine the stitches for any signs of incorrect tension.
- Adjust the dials as necessary until you achieve optimal tension.
Troubleshooting Common Tension Issues
Loose Stitches:
- Increase the upper tension slightly.
- Check if the needle is threaded correctly.
- Use a heavier thread or a larger needle.
Puckered Stitches:
- Decrease the bobbin tension slightly.
- Ensure the bobbin is wound evenly.
- Try a different thread or fabric.
Breaking Thread:
- Reduce the tension on both the upper and lower threads.
- Check for any burrs or nicks on the needle.
- Replace the needle with a new one.
Tips for Optimal Tension
- Use high-quality thread and needles.
- Clean and oil your sewing machine regularly.
- Experiment with different tension settings for different fabrics and threads.
- Refer to your sewing machine manual for specific instructions.

Answers to Your Questions
1. Why is my thread breaking when I sew?
- Excessive tension, a dull or damaged needle, or incorrect threading can cause thread breakage.
2. How do I adjust the bobbin tension on a machine without a bobbin tension dial?
- Use a small screwdriver or tweezers to gently loosen or tighten the screw on the bobbin case.
3. What is the ideal tension setting for all fabrics?
- There is no universal ideal tension setting. It varies depending on the fabric, thread, and needle used. Start with a medium setting and adjust as needed.
4. Can I use different thread weights in the upper and lower threads?
- Yes, but it may require adjusting the tension accordingly. Use a heavier thread in the upper thread if you want a more prominent stitch.
5. How often should I check my sewing machine tension?
- Check the tension whenever you change the thread, fabric, or needle. Regular cleaning and maintenance can also help maintain optimal tension.
