What number should the tension be on a sewing machine?
As the bobbin thread tension is factory-set and wouldn’t usually be adjusted for normal sewing. So we’ll be talking only about the top thread tension since that’s where you’d usually make the adjustments. The dial settings run from 0 to 9, so 4.5 is generally the ‘default’ position for normal straight-stitch sewing.
When should I adjust the bobbin tension?
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 is my thread looping 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.
