How to Adjust Tension on Sewing Machine Singer: Expert Tips
Introduction to Sewing Machine Tension
Sewing machines are like magic. They stitch fabric together with ease. But sometimes, the stitches are not perfect. This is because of tension. Tension is important in sewing. It keeps the thread tight and neat. If the tension is off, the stitches will be messy.
In this article, we will learn about tension. We will also learn how to adjust it. This is for Singer sewing machines. Let’s make your sewing perfect!
What is Tension?
Tension is like a tug-of-war. It is the pull on the thread. There are two threads in sewing. The upper thread and the lower thread. Both need to be balanced. If they are not, problems occur. The stitches may be too loose or too tight.
When the tension is right, the stitches look good. The fabric lies flat. The sewing is strong.

Signs of Incorrect Tension
How do you know if the tension is off? Here are some signs:
- Loops on the bottom side of the fabric.
- Tight or puckered fabric.

- Uneven stitches.
If you see these, check the tension.
Adjusting Upper Thread Tension
Find The Tension Dial
First, find the tension dial. It is on the front of the machine. It has numbers on it. These numbers adjust the tension.
Set The Dial To Mid-range
Set the dial to a middle number. This is usually 4 or 5. This is a good place to start.
Test The Stitches
Use a piece of scrap fabric. Sew a few lines. Look at the stitches.
Make Small Adjustments
If the stitches are loose, turn the dial up. If they are tight, turn it down. Make small changes. Test again after each change.
Adjusting Bobbin Tension
Check The Bobbin Case
Sometimes, the bobbin tension needs adjusting. Open the bobbin case. Take out the bobbin.
Use A Screwdriver
Find the small screw on the bobbin case. Use a screwdriver to turn it. Turn it right to tighten. Turn it left to loosen.
Test The Bobbin
Put the bobbin back in. Sew on scrap fabric. Check the stitches. Adjust if needed.
Tension Tips and Tricks
