Sewing machine tension is how tight the threads are pulled as you sew. The tighter your thread (or the higher your tension), the tighter your stitches. With proper tension, your sewing machine needle moves up and down, the bobbin thread is pulled up, and you get nice, neat, even stitches.
What number should the tension be on a 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. If you are doing a zig-zag stitch, or another stitch that has width, then you may find that the bobbin thread is pulled through to the top.
What will happen if the tension of the sewing machine is too loose?
If both tensions are too tight, the seam may pucker, or break easily when stretched (test this on the more stretchy crossgrain, with at least a 6-inch seam). If both are too loose, the seam will gap when pressed open, exposing the threads between the sections.
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.
How do I know if my bobbin tension is correct?
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 doesnt budge, your bobbin tension is too tight.
What should the bobbin tension be set at?
Proper bobbin tension is essential to good embroidery. If tension is too tight, unwanted bobbin thread may begin to show on top of your garment and you may begin to experience frequent thread breaks which wastes time and money.

Why is my sewing machine making loops underneath?

Why is my Singer sewing machine bunching thread on the bottom?
Thread looping on the underside of the fabric is always an indication that the upper thread is not correctly threaded. This happens when the upper thread is not correctly placed in the tension mechanism and has not been threaded through the take-up lever.
How do you adjust thread tension?
You should see a small screw on the flat/closed side of the bobbin case. Turning the screw a tiny bit counterclockwise will loosen the bobbin tension; turning it clockwise will tighten the tension.
