Loose thread tension refers to a condition in which the tension on the thread being sewn by a sewing machine is not tight enough. When the tension is too loose, the top thread will appear on the right side of the fabric and may also cause the bottom thread to loop or become visible on the right side of the fabric.

In addition to affecting the appearance of the stitches, loose thread tension can also cause problems such as thread breakage, skipped stitches, and puckering of the fabric.

How do you fix loose thread tension? To prevent loose thread tension, it is important to regularly check and adjust the tension on the thread as needed, and to use the appropriate thread for the type of fabric you are sewing. Additionally, proper maintenance and cleaning of your sewing machine can help ensure that the machine is working correctly and producing the desired tension.

To fix loose thread tension on a sewing machine, you will need to adjust the tension control dial. Here are the steps to follow:

Turn off the machine

Before making any adjustments, turn off the machine to ensure that it is safe to work on.

Raise the presser foot

Raise the presser foot of the machine to release the tension on the thread.

Cut the thread

Cut the thread that is currently in the machine.

Turn the tension dial

Locate the tension dial, which is usually located on the top of the machine. Turn the dial clockwise to increase the tension or counterclockwise to decrease the tension.

Test the tension

Sew a few stitches on a scrap piece of fabric and examine the stitches. If the top thread is too loose, the bottom thread will show on the right side of the fabric. If the top thread is too tight, the bottom thread will show on the wrong side of the fabric. If the tension is correct, the threads will interlock evenly and not show on either side of the fabric.

Repeat the process

If the tension is not correct, repeat the process of adjusting the tension dial and testing the machine until you achieve the desired tension.

Maintain the tension

Regular use and handling of your sewing machine can cause the tension to become out of balance. Regularly checking and adjusting the tension as needed will help ensure that you are able to produce high-quality stitches and prevent problems such as thread breakage and skipped stitches.

Check the thread

Before making any adjustments to the tension, it’s important to make sure that the thread you are using is appropriate for your sewing project. Check the sewing thread for knots, tangles, or other defects that could affect its ability to move smoothly through the machine.

Clean the machine

Dirt and debris can accumulate in the tension assembly and cause the thread tension to be affected. Clean your sewing machine regularly to ensure that it is working correctly.

Replace worn parts

Over time, the tension spring and other parts of the tension assembly can wear out, causing the tension to be affected. If you suspect that your machine has worn out parts, it’s best to replace them to ensure that the machine is functioning correctly.

Consult the manual

If you’re still having trouble fixing loose thread tension, consult the manual for your sewing machine. Many manuals include step-by-step instructions for adjusting the tension, and they may also include troubleshooting tips that can help you resolve any issues you’re having.

Seek professional help

 If you’re unable to resolve the issue with loose thread tension, consider seeking help from a professional. A professional can diagnose any problems you’re having and repair your sewing machine if necessary.

Frequently Asked Questions (FAQ’s)

How do I tighten my thread tension?

To increase the top thread tension, turn the dial that controls the thread tension in the clockwise direction. It is conceivable that the right thread tension cannot be established if the top thread is not threaded correctly or if the bobbin is not placed correctly.


It is important to keep in mind that the process of adjusting the tension on a sewing machine can be complex, and it is recommended to seek the assistance of a professional if you are not familiar with the process. Additionally, many newer models of sewing machines have electronic tension control systems, which may require special tools or techniques to adjust. If you are unsure about how to properly adjust the tension on your machine, it is best to refer to the machine’s manual or contact a professional for assistance.
