Sewing Machine Needles Explained — Types, Sizes & Which to Use

The wrong needle is behind more sewing frustrations than almost anything else. Skipped stitches, shredded thread, fabric snags, broken seams — most of these trace back to using the wrong needle type, the wrong size, or a needle that's simply past its best.

This guide covers every needle type we stock, organised by machine type, so you can find the right needle for your machine and fabric quickly. Use the links below to skip ahead.


Home Sewing Machine Needles

Most home sewing machines use the 130/705H needle system (also called HAx1). This is the standard for domestic machines from Brother, Janome, Bernina, Pfaff, Husqvarna, and most other home sewing brands.

Within this system, different needle types are engineered for different fabrics. Using the right type makes a measurable difference to stitch quality.

🧵 For Woven Fabrics

Most everyday sewing falls here. If you're working with cotton, linen, denim, or anything that doesn't stretch, one of these is your needle.

👕 For Knits & Stretch Fabrics

Don't make the mistake of reaching for a universal needle here. Knits need a ball point or stretch-specific needle — the difference shows up immediately in your stitch quality.

Overlocker / Serger Needles

Overlockers are fussier about needles than home machines — the wrong needle in an overlocker doesn't just affect stitch quality, it can cause the machine to skip or jam entirely. Always check your machine manual before ordering.

Industrial Sewing Machine Needles

Industrial machines run faster, hit harder, and demand more from their needles. The needle system you need depends entirely on your machine type — there's no universal industrial needle, so always verify against your machine manual before ordering.

Lock-stitch Machines (DBx1)

DBx1 is the workhorse of the industrial world — the standard needle system for industrial lock-stitch machines, which are the most widely used type in garment manufacturing and tailoring.

Other Industrial Systems

Running a chainstitch, cover-stitch, or post-bed machine? These are the needles you need — and they're not interchangeable with DBx1.

Understanding Needle Sizes

Sewing needles use a dual numbering system — a European metric size and an American size, shown together (e.g. 80/12). Both numbers refer to the same needle; the higher the number, the thicker the needle.

Size Fabric weight Examples
60/8 – 65/9 Very fine / sheer Chiffon, organza, voile
70/10 – 75/11 Lightweight Batiste, fine cotton, silk
80/12 Medium weight Cotton, linen, poplin, jersey
90/14 Medium-heavy Denim (light), canvas, wool
100/16 Heavy Denim, upholstery, thick canvas
110/18 – 120/19 Very heavy Heavy denim, leather, multiple layers

💡 When in doubt, start with an 80/12 for medium-weight fabrics. Go up a size if the needle struggles; go down if it leaves visible holes.


Frequently Asked Questions

How often should I change my sewing needle?

As a general rule, change your needle every 8–10 hours of sewing, or at the start of every new project. A dull needle is the most common cause of skipped stitches, puckering, and thread breakage — and needles are inexpensive enough that there's no reason to push them past their best.

Can I use a universal needle for stretch or knit fabric?

You can, but you'll likely get skipped stitches. Universal needles have a slightly rounded point that works on most wovens, but stretch and knit fabrics need a dedicated stretch or jersey needle — the point geometry and scarf are specifically designed to prevent the needle from deflecting off the looper, which is what causes skipped stitches on knits.

What Schmetz needle is best for denim?

The Schmetz Jeans (H-J) needle is purpose-built for denim, canvas, and twill. Its reinforced blade and medium ball point displace fabric threads rather than piercing them, which reduces penetration force and needle breakage. Use size 90/14 for lighter denim and 100/16 or 110/18 for heavier weights.

What's the difference between Schmetz ELx705 and ELx705 SUK?

Both are overlocker/serger needles, but they're designed for different fabrics. The ELx705 is for woven fabrics, while the ELx705 SUK has a ball point specifically for knit and stretch fabrics. If you're overlocking jersey or stretch fabric and getting skipped stitches, switching to the SUK version usually solves it.

What do the numbers on Schmetz needles mean?

Schmetz needles show both European (metric) and American sizes, e.g. 80/12. The European number (80) refers to the needle blade diameter in hundredths of a millimetre; the American number (12) is a legacy sizing scale. Both refer to the same needle — the higher the number, the thicker the needle and the heavier the fabric it's suited for. See the sizing chart above for a full reference.

Are Singer 2020 and Schmetz Universal the same needle?

They're compatible — both use the 130/705H system and will fit the same machines. The Singer 2020 is Singer's branded version of the universal needle, while Schmetz Universal is the same system from a specialist needle manufacturer. Either will work in most home sewing machines.
