Choosing the Right Machine Needle
How needle type and size change the way fabric sews, with a table matching common fabrics to needles.
What you will learn
- Matching needle to fabric
- Reading needle sizes
- Knowing when to replace a needle
Why the needle matters
The wrong needle causes skipped stitches, snagged fabric, puckered seams and broken thread. A needle that is too thick leaves visible holes in fine fabric. One that is too thin bends or breaks in heavy fabric.
Needles have two numbers, such as 80/12. The first is the metric size (the shaft diameter in hundredths of a millimetre, so 80 is 0.8 mm). The second is the older American size. A lower number is thinner and suits finer fabric.
Common needle types
- Universal: a slightly rounded point. It is the standard needle for woven fabrics such as cotton, linen and polyester blends. It also works on some stable knits.
- Ballpoint or jersey: a rounded tip that slides between the knit loops instead of piercing them. Use it on stretch knits such as T-shirt fabric to avoid holes and runs.
- Stretch: similar to ballpoint, with a scarf shaped to prevent skipped stitches on very stretchy fabric such as elastic knit.
- Jeans or denim: a sharper point and stronger shaft for dense, thick woven fabric such as denim and canvas.
Needle and fabric table
| Fabric | Needle type | Size |
|---|---|---|
| Lightweight cotton, voile, lawn | Universal | 70/10 or 80/12 |
| Quilting cotton, poplin, shirting | Universal | 80/12 |
| Linen, medium cotton, chambray | Universal | 80/12 or 90/14 |
| T-shirt jersey, cotton knit | Ballpoint or jersey | 70/10 to 90/14 |
| Very stretchy knit, activewear | Stretch | 75/11 or 90/14 |
| Lightweight denim, twill | Jeans or denim | 90/14 |
| Heavy denim, canvas | Jeans or denim | 100/16 |
These are starting points. Test on a scrap of the real fabric with the real thread before sewing the project. If stitches skip or the fabric snags, try another size or type.
Replace needles regularly
A needle goes dull or develops a tiny burr after use. Replace it at the start of each new project, after about 8 hours of sewing, and at once if you hit a pin or hear a clicking sound. A bent needle can also damage the needle plate or the bobbin case.
Follow your machine's needle system and bobbin specifications. Needles come in different shank styles. The wrong style may not sit properly and can damage the machine. Your manual lists the correct system and how to fit it.
Tips for a neat result
- Keep a pin cushion or small box for used needles and bend nothing back into shape. Throw bent needles away.
- Write the needle type and size on a sticky note on the machine so you know what is fitted.
Common mistakes and fixes
Stitches are skipped on a knit.
A universal needle can miss loops on stretch fabric. Fit a new ballpoint or stretch needle.
Small holes appear along the seam line of a fine fabric.
The needle is too thick or dull. Fit a new, thinner needle (60/8 or 70/10).
The needle bends or breaks on denim.
A thin needle was pushed through thick layers. Use a jeans needle, sew slowly and turn the handwheel by hand over thick seams.
