You can learn how to adjust bobbin tension on Janome sewing machine in just two steps. As you’ll find out in this tutorial, the bobbin tension adjustment in Janome is not different from other machines. You will also know how to fix common bobbin issues to keep your unit working smoothly.
But what if you need to service your Janome? We have written a quick tutorial on how to take apart a Janome sewing machine that you can check out. Read that to help you with maintaining your device.
How To Adjust Bobbin Tension On Janome Sewing Machine Correctly
Step 1. Find the screw near the bobbin
- Read and study the Janome manual of the specific model you have
- Find the bobbin and remove it from the compartment
- Use a screwdriver on the screw located at the bobbin side
Step 2. Loosen or tighten the screw as needed
- Turn the bobbin screw tightly or loosely to adjust the bobbin tension on the Janome sewing machine
- Make small movements with the screwdriver for each adjustment
- Turn the screw to the right to increase the bobbin tension or turn it to the left to decrease the bobbin tension
- Return the bobbin to its case and practice stitches to check the newly set bobbin tension
What should be the bobbin tension on the Janome sewing machine?
By checking the bobbin case, you can determine that you set the bobbin tension on the Janome sewing machine correctly. Notice the bobbin case when the thread unwinds because it should only drop one to two inches. Therefore, if the bobbin case slips off, you need to tighten the tension but loosen the tension if the case won’t move.
How Do You Adjust Bobbin Tension?
You don’t need to modify the bobbin tension in most cases because the manufacturer already set it for you. Adjusting the needle thread tension is enough, and some computerized units even have electric tension control.
For front-loading bobbin sewing machines:
- Find the screw on the bobbin case and turn it to increase or decrease the bobbin tension
- For machines with two screws, be careful not to turn the screw that holds the tension plate
- The screw shouldn’t be tightened or loosened in big movements; a quarter turn is enough
- Use a marker to remember the factory set bobbin tension because this tension is enough for most projects
- Test the new bobbin tension setting on a scrap fabric each time
For drop-in bobbin sewing machines:
- Remove the bobbin case and find the screw that you can tighten or loosen
- Do not move the screw that secures the tension plate
When to adjust bobbin tension
- When using very thick or very fine threads and adjusting the needle thread tension is not enough to make neat stitches
- When using uncommon thread weights and types
- When shirring with elastic thread
- When stippling or making free motion
- When using twin needles
- When the bobbin thread keeps breaking
How to check the bobbin tension
- Bobbin tension gauge on longarm and mid-arm sewing machines
- Bobbin tension meter on any front-loading bobbin sewing machine
How Do I Fix The Bobbin Tension On My Sewing Machine?
Test if the bobbin tension is right
Hold the bobbin by the thread, and when it doesn’t move, the tension is too tight. On the contrary, the tension is too loose if the case drops quickly. So you want the case only to drop a little, and the thread still has some resistance.
Adjust the bobbin tension
Tighten or loosen the screw on the bobbin slightly according to the necessary adjustment. Note the original bobbin tension setting so you can return the bobbin tension to it after the current project.
Why Is My Thread Looping Underneath The Fabric?
Do you notice your thread looping on the back of the fabric? This indicates that your top thread tension is too loose compared to the bobbin thread tension. Therefore, the bobbin thread pulls the top thread underneath the material. To solve this issue, loosen both thread tensions because tightening only the top thread can cause breakage.
Why Does My Bottom Thread Keep Jamming?
- The bobbin tension is too tight
- The bobbin case needs realignment or replacement
- The bobbin is not threaded properly
- The bobbin is wrong for the machine
- There is not enough thread tail on the bobbin
- The bobbin case is filled with debris
- Using the wrong needle on the sewing machine
- The sewing machine needs lubrication
How To Avoid Bobbin Issues
Adjusting the bobbin tension is unnecessary in most cases, but common bobbin issues can be easily avoided by remembering the following:
- Make sure that the bobbin is threaded properly
- The bobbin should always be inserted in its case correctly
- Keep the sewing machine clean and oiled
- Use the correct needle and thread for the project
- Set the machine properly
And that’s it! We just discussed how to adjust bobbin tension on Janome sewing machine, and found out it’s simply turning the screw to loosen or tighten it. However, consider changing the bobbin tension after only you tried adjusting the needle thread tension.

When using a twin needle the bobbin tension (I assume) is too tight as it creates a tunnel effect in the right side of fabric. How can I correct this?
