Most sewing problems that get blamed on the machine start at the needle. Skipped stitches on a T-shirt, thread shredding halfway through a seam, a needle snapping on denim. The fix is usually a two dollar packet, not a service visit.
This page has two ways to get your answer. Use the needle selector just below if you want your answer in ten seconds: pick your fabric, pick its weight, pick the job, and tell it which brand you buy. If you would rather read the whole picture, the charts below cover the types of sewing machine needles, the sewing machine needle sizes in both sizing systems, and the one brand trap that catches a lot of people out.

Which sewing machine needle do I need?
Pick your fabric, its weight, and what you are sewing. You get the needle type, the size in both sizing systems, and the right name for your needle brand.
The fabric and weight you picked above are used here too, so keep them set to what is under your presser foot.

One honest note before the charts. Needle type names are not standardised across brands. A type name on a Schmetz pack and the same type name on an Organ pack can describe two different points. The selector handles that for you, and the brand section further down explains it properly.
How to use the needle selector
- Pick your brand. Schmetz or Organ. This changes some answers, because the two brands do not always use a name for the same point.
- Pick your fabric. Woven, knit, denim and heavy fabric, delicate fabric, leather or vinyl, quilting, or machine embroidery.
- Pick the weight. Light, medium or heavy. Needle size follows fabric weight, so this step sets your size.
- Pick the job, or switch to Fix a problem. The job list includes low stretch and high stretch knits, topstitching, and twin needle hems. The problem mode covers skipped stitches, needles that keep breaking, puckering, and thread that keeps shredding, and it gives you the needle fix first, in the order you should try things.
Every result gives you the type, the EU size and the US size, why that needle fits, and when to change it.
Sewing machine needle chart
Use this as the standing reference. Sizes are the working range for each type, and the size you land on inside that range depends on fabric weight and on your thread.
| Needle type | Sizes (EU / US) | Best for | Notes |
|---|---|---|---|
| Universal | 70/10 to 100/16 | General woven fabric: cotton, linen, blends | The default needle. Size 80/12 is the standard start for a medium weight woven. |
| Ballpoint / Jersey | 75/11 to 90/14 | Stable knits, cotton jersey | Rounded point slips between knit loops instead of cutting them. Ballpoint and Jersey are two labels for the same job. |
| Stretch | 75/11 to 90/14 | Knits with lycra or spandex, T-shirts, activewear | The answer once a knit has real stretch fibre in it. |
| Super Stretch | 75/11 to 90/14 | Swimwear, very elastic fabric | For the highest stretch fabrics, past what a standard stretch needle handles well. |
| Microtex / Sharp | 60/8 to 90/14 | Silk, satin, cotton poplin, tightly woven fabric | Slim, very sharp point. Dulls faster than most types, so change it more often. |
| Jeans / Denim | 90/14 to 110/18 | Denim, canvas, duck cloth, layered heavy fabric | Stronger shaft for dense fabric. See the brand section: this name means different points on Schmetz and Organ. |
| Leather | 90/14 to 110/18 | Real leather, faux leather, vinyl | Wedge shaped cutting point. Never use it on woven or knit fabric, it slices the yarns. |
| Quilting | 75/11 to 90/14 | Piecing, quilting through the quilt sandwich | Built for accurate work through several layers. |
| Embroidery | 75/11 to 90/14 | Machine embroidery | Larger eye, which gives embroidery thread room to move. |
| Topstitch | 80/12 to 100/16 | Topstitching, thick threads | The type to reach for when the thread itself is heavy. |
| Twin | 70/10 to 90/14 | Hems on wovens and knits | Two parallel rows on top, a zigzag formed with the bobbin thread underneath. Match the size to the fabric weight. |
Schmetz vs Organ: the same name can be a different needle
This is the part of needle buying that nobody warns beginners about, and it is the reason the selector asks for your brand first.
Jeans needles. On a Schmetz pack, a Jeans needle is a ballpoint style point with a reinforced shaft. On an Organ pack, a Jeans needle is a sharp point, close to a Microtex, also with a reinforced shaft. Both are strong needles for denim, but they are not the same point wearing two labels. If a guide tells you to buy a jeans needle and your results are off, the brand on your pack is one of the first things worth checking.
Silk. The advice splits the other way. Schmetz points you to a sharp needle for silk, its Microtex. Organ sells a dedicated Silk needle with a ballpoint point. Neither brand is being careless. They have simply built different answers to the same fabric, and they have labelled them differently too.
The practical rule is simple. Decide your type using the fabric, then buy that type in your own brand, and read the point description on the pack rather than trusting the name alone. Where the two brands genuinely disagree, the selector tells you which way your brand goes.
A second naming quirk worth knowing: ballpoint and jersey are the same idea under two labels. Which word you see on the pack depends on the brand and on the market the pack was made for, which is why a US sewer and a UK sewer can describe the identical needle with different words.
Needle size conversion: EU and US sizes
Every home sewing machine needle carries two size numbers. The bigger number is the European metric size. The smaller one is the US size, sometimes called the Singer size. They are the same needle. A pack printed 80/12 is one needle, not two.
| EU (metric) size | US / Singer size | Typical use |
|---|---|---|
| 60 | 8 | Finest work, silk and very light fabric |
| 65 | 9 | Very light fabric |
| 70 | 10 | Light woven fabric, light quilts |
| 75 | 11 | Light knits, quilting, embroidery |
| 80 | 12 | Medium woven fabric, the everyday default |
| 90 | 14 | Heavier woven fabric, denim starting point, thick knits |
| 100 | 16 | Heavy fabric, denim, topstitching |
| 110 | 18 | Heaviest denim, canvas, leather |
Size goes up as fabric gets heavier, and it also has to suit your thread. A thick thread in a small needle will shred, no matter how good the needle is. When a seam misbehaves and the type looks right, moving one size up or down is a fair test.
When to change your needle
Needles are consumables. They are not a part of the machine, they are a supply, and they wear out quietly. A worn needle rarely looks worn. It just starts costing you stitches.
- Change at the start of a new project. It is the cheapest habit in sewing and it removes a whole category of mystery problems.
- Change after about 8 hours of sewing. That is the working rule used by manufacturers and sewing teachers alike.
- Change immediately if it bends, burrs, or hits a pin. A damaged needle will damage fabric and can break its own replacement if the cause is still there.
- Change sooner with Microtex. Sharp points dull faster, and on silk a dull sharp needle snags instead of sewing.
- Reach for a fresh needle first when stitches go wrong. Skipped stitches, sudden tension trouble and a change in the sound of the machine are all reasons to swap the needle before touching any dial.
FAQs
What gauge is a sewing machine needle?
Gauge is the needle size, meaning how thick the needle blade is. On a home sewing machine needle it is written as two numbers, the European metric size and the US size, so 80/12 is one needle at one gauge. Higher numbers mean a thicker, stronger needle for heavier fabric. Lower numbers mean a finer needle for light and delicate fabric.
What size needle do I need for a medium cotton fabric?
Start with a Universal 80/12. It is the standard medium woven combination, and it is what most machines are set up around. Go to 70/10 for a light cotton and 90/14 if the fabric is heavy or you are sewing through several layers.
What needle do I use for jersey and T-shirts?
It depends on the stretch in the fabric, which is the bit most guides skip. For a stable cotton jersey with little or no lycra, use a Ballpoint / Jersey needle. If the T-shirt fabric has lycra or spandex in it, use a Stretch needle instead, 75/11 for most T-shirt weight fabric. For swimwear and very elastic fabric, use Super Stretch.
Can I use a ballpoint needle on woven fabric?
You can, and the machine will sew, but it is not the best tool for the job. A ballpoint point is rounded so it can slip between knit loops. On a woven fabric it has to push between tightly packed yarns, which can mean less accurate stitches and more puckering on fine fabric. A Universal, or a Microtex on a tightly woven fabric, will give you a cleaner result.
Why does my machine keep skipping stitches on knits?
Nine times out of ten it is the needle. A universal needle, or a worn ballpoint, will skip on a knit, and it gets worse when the fabric has elastane in it. Fit a fresh Stretch needle first. If the knit is a stable jersey with no stretch fibre at all, a fresh Ballpoint / Jersey is the other half of the answer. Only start looking at threading and tension once a fresh, correct needle is in the machine.
Are Schmetz and Organ needles interchangeable?
They fit the same home machines, because home machines use the same needle system. What is not interchangeable is the advice. Type names and point shapes differ between the brands, a Jeans needle being the clearest example, so a recommendation written for one brand does not always translate word for word to the other. Buy the type your fabric needs, in the brand you use, and read the point description on the pack.
How do I read the Schmetz colour band?
Schmetz prints a colour band on the needle so the type can still be identified once the needle is out of its pack and sitting in a pincushion with five others. Match the band to the legend printed on your Schmetz pack to confirm the type, then read the size from the numbers on the pack. The band tells you the type, the numbers tell you the size. It is a Schmetz system, so on an Organ pack go by the printed type name and sizes instead.
Can I sew leather with a normal needle?
Not well, and not for long. Leather and vinyl have no woven yarns for a normal point to pass between, so the needle has to cut its way through. A Leather needle has a wedge shaped cutting point made for exactly that. Never run it the other way either: a leather needle on woven or knit fabric cuts the yarns and leaves little slices along your seam line.
Starter packs worth having
If you are building a needle drawer from nothing, a variety pack beats five separate packs. You get the types above in the sizes you will actually reach for, and you can replace a needle mid project instead of sewing on with a dull one.
Schmetz variety pack. A mixed Schmetz pack is the sensible starter if your machine came with Schmetz or you want the colour band system. Check the pack contents before you buy, because the mix changes between packs. See Schmetz needle variety packs on Amazon
Organ variety pack. The Organ equivalent, and the better pick if you already buy Organ. Same advice as above: read the contents list, and remember that Organ type names do not always match Schmetz ones. See Organ needle variety packs on Amazon
Schmetz stretch pack. Worth its own pack if you sew T-shirts, leggings or activewear regularly, because stretch needles are the ones that run out first. Buy it in 75/11 if you are only buying one size. See Schmetz stretch needle packs on Amazon
