Most sewing machines have tension dials that run from 0 to 9. So for normal projects and standard stitches, your sewing machine’s tension should be 3, 4, or 5. 4.5 is usually ideal, but some machines may not have that option.

What is the perfect tension on sewing machine?
The dial settings run from 0 to 9, so 4.5 is generally the ‘default’ position for normal straight-stitch sewing. This should be suitable for most fabrics.
How do you know thread tension is correct?
A correct thread tension looks smooth and flat on both sides of the seam. The needle and bobbin threads interlock midway between the surfaces of the material.
How do I know if my sewing machine tension is too high?
If the tension is too tight, the fabric can pucker and the bobbin thread may be visible on the top side of the fabric. If the tension is too loose, you may see visible loops on the top side of the fabric and the spool thread might be visible on the underside.
What number is tighter tension on sewing machine?
You’ve probably noticed the tension regulator on your sewing machine. It’s usually a dial with the numbers 3, 4, and 5 highlighted or circled. This regulator tightens, or loosens, the tension discs that the thread passes down through before it goes up and through the looper.
What tension should thick fabric be?
For thick upholstery fabric, use upholstery weight thread with a size 16/100 or 18/110 sharp needle. If you’re sewing denim or canvas, try heavy duty thread with a denim needle size 90/14.
What tension should I use for cotton?
Cotton requires a moderate tension setting, usually between three and four. Always start adjusting your tension settings with your upper tension.
What are the settings for a straight stitch on a sewing machine?
Set the machine for straight stitch, with a stitch length of 3 to 3.5mm. Use a SINGER Topstitching Needle, size 90/14 for medium weight fabrics, or a SINGER Topstitching needle, size 100/16 for heavier fabrics.
Why is my fabric bunching up when I sew?
Cause. Tension pucker is caused while sewing with too much tension, thereby causing a stretch in the thread. After sewing, the thread relaxes. As it attempts to recover its original length, it gathers up the seam, causing the pucker, which cannot be immediately seen; and may be noticeable at a later stage.
How tight should bobbin tension?
Swiftly pull up on the thread. The thread should unwind just slightly and the bobbin case should drop an inch or two. If the thread unwinds without resistance and the case slips to the floor, your bobbin tension is too loose. If the bobbin case doesn’t budge, your bobbin tension is too tight.
Why does the thread bunch up underneath?
Your Thread Tension Is Too Tight
Sewing machine manufacturers suggest that you don’t mess with your bobbin thread tension too much, but you should adjust your upper thread tension if you keep getting bunched up thread underneath your fabric. If your tension is too tight, it can pull your thread and break it.
Why is the stitching loose underneath?
Cause: The tension of the upper thread is too weak or the tension of the lower thread is too tight. Solution: Tighten the tension of the upper thread, or loosen the tension of the lower thread, until the tensions of both threads are correctly balanced. Cause: The machine is not threaded correctly.
Why does my thread keep pulling out of the needle?
Your Sewing Machine Thread Tension Could Be Off
One of the most common issues leading to a needle that keeps unthreading is a sewing machine with the wrong thread tension in place. Thread tension at the top that’s either too high or too low can result in this issue.
Why is my sewing machine making loops underneath?
A: Looping on the underside, or back of the fabric, means the top tension is too loose compared to the bobbin tension, so the bobbin thread is pulling too much top thread underneath. By tightening the top tension, the loops will stop, but the added tension may cause breakage, especially with sensitive threads.
What tension should I use for zig zag stitch?
What tension should I use for the zigzag stitch? The thread tension plays a significant role in stitching properly. Normally a sewing machine has a setting options dial from 0 to 9. The default 4.5 is considered as an ideal setting for zigzag stitch on almost all types of fabrics.
What is the normal stitch length?
2.5 mm
Here are some common terms and what they mean for you stitch length settings: Standard stitch length: Refers to a 2.5 mm stitch length. Commonly used for regular seams when assembling two pieces of fabric.
How do I stop Zig Zag puckering?
Solution: Rethread the machine. If that doesn’t work, adjust the tension. Explanation: When the thread loops on the backside of the fabric, that’s an indication the upper thread is not threaded correctly. The thread is not receiving the tension it needs.
