Sewing machine needle sizes are printed as two numbers, like 80/12: the first is the metric size and the second is the US size. Lower numbers are finer needles for lighter fabrics; higher numbers are thicker needles for heavier fabrics. For most beginners, a Universal 80/12 handles medium woven cotton, a 70/10 suits lightweight fabrics, and a 90/14 or 100/16 suits heavier ones. For knits, denim, leather and specialty threads, the needle type matters as much as the size.
The charts below follow the needle makers' own references: SCHMETZ's home needle guide, SINGER's needle guide and Organ's household range. When your machine manual says something different, follow the manual.

How to Read a Needle Package
Every home machine needle package shows three things:
- The needle system, usually 130/705 H. SCHMETZ explains that home machines need a flat-shank needle with a scarf. It lists 130/705 H as equivalent to 15x1 H and to SINGER Style 2020. Organ sells the same system as HAx1. If your machine is a regular home sewing machine, this is almost certainly your system.
- The needle type, often as a letter after the H. SCHMETZ uses H-J for Jeans, H-M for Microtex, H-Q for Quilting, H-S for Stretch and H-E for Embroidery.
- The size, shown as metric/US, such as 90/14.
What the size numbers mean
The metric number is the blade diameter. SCHMETZ puts it simply: "size 75 is .75mm." The US number is an older scale that rises along with it. SINGER notes that most packaging shows both systems.
Sewing Machine Needle Sizes Chart
Here are the standard sizes in SCHMETZ's Universal range, with typical fabric weights. The fabric examples come from SCHMETZ's needle and fabric recommendations.
| Metric / US | Weight | Example fabrics (SCHMETZ recommendations) |
|---|---|---|
| 60/8 | Very fine | Batiste, chiffon, organza, voile |
| 65/9 | Very fine | Fine lingerie and silk jersey (Stretch needle) |
| 70/10 | Light | Cambric, light cottons, georgette, taffeta |
| 75/11 | Light to medium | Knits and lingerie (Stretch); piecing (Quilting) |
| 80/12 | Medium | Quilting cotton, poplin, chambray |
| 90/14 | Medium to heavy | Chambray, corduroy, flannel, terry cloth |
| 100/16 | Heavy | Corduroy, felt, wool blends, denim |
| 110/18 | Very heavy | Heavy denim, canvas, flannel |
| 120/19 | Extra heavy | Thick leather (Leather needle) |
SCHMETZ's guidance on choosing: pick the size according to thread thickness and the type according to the fabric. Thicker thread needs a larger needle, so the thread fits in the needle's groove and eye without shredding.

Twin needle numbers
Twin needles carry two numbers, such as 4.0/90. The first is the distance between the needles in millimeters (SCHMETZ calls this NE). The second is the needle size. Check your machine's maximum stitch width before using wide twins: the distance must fit your needle plate opening.

SINGER and Organ Equivalents
SINGER needle styles
SINGER labels its home needles by style number rather than letter. From SINGER's needle guide:
| SINGER style | Type | Use for |
|---|---|---|
| 2020 | Universal | Woven fabrics |
| 2045 | Ball Point | Knit fabrics |
| 2026 | Denim/Jeans | Denim, jeans, canvas |
| 2032 | Leather | Leather and vinyl |
| 2025 | Twin | Decorative stitching, parallel rows |
| 2040 | Hemstitch/Wing | Heirloom sewing on linen and cotton |
| 2000 | Regular Point | Woven fabrics on embroidery machines |
| 2001 | Chromium Ball Point | Knit fabrics on embroidery machines |
SINGER's sizing guidance matches SCHMETZ's: smaller needles for lightweight fabrics and delicate threads, larger sizes for heavier materials.
Organ needles
Organ sells its household needles in the same HAx1 system. Its range includes Universal, Jersey, Super Stretch, Jeans, Leather, Microtex, Quilting, Embroidery, Metal, Top Stitch, Titanium, Twin and Twin-Stretch needles. The type names line up with the SCHMETZ chart above, so use the same fabric guidance and check the size on the pack.
Serger needles are different
Many sergers use a different system. SCHMETZ lists ELx705, BLx1 and DCx1 for domestic sergers and special machines, and SINGER uses styles 2054 and 2022 for some of its sergers. Always check your serger's manual. Our best sergers for beginners lists the needle system for each pick where the maker publishes it.
How to Change a Sewing Machine Needle
- Turn off the machine, and raise the needle to its highest position with the handwheel.
- Lower the presser foot. Lay a scrap of paper over the needle plate opening so a dropped needle can't fall into the machine (a SINGER tip).
- Loosen the needle clamp screw and pull the old needle down and out.
- Insert the new needle with the flat side of the shank facing the back (on most home machines), and push it up as far as it goes.
- Tighten the clamp screw firmly.
When to Change Your Needle
SCHMETZ's rule of thumb is to change the needle after every 8 hours of sewing or after each project. SINGER says every 8 to 10 hours. Change it immediately if you see any of the signs SCHMETZ lists:
- Broken or shredded threads
- Skipped or uneven stitches
- Puckered or damaged fabric
- A popping sound as the needle goes through the fabric
Common Mistakes
- Using one needle for everything. A Universal 80/12 is a great default, but knits want Jersey or Stretch, and denim wants Jeans.
- Sewing knits with a sharp needle. It can pierce the knit loops and cause runs or skipped stitches.
- Using a Leather needle on fabric. Its cutting point slices woven and knit fibers. SCHMETZ warns against it.
- Forcing thick seams with a small needle. It deflects and can break. Size up and slow down.
- Ignoring thread size. Topstitching thread needs a Topstitch needle or a larger size.
- Waiting until the needle breaks. Most "machine problems" beginners report, like skipped stitches and snags, are worn needles.
- Using the wrong system. Industrial and serger needles don't fit home machines, and vice versa.

FAQ
What do the two numbers on a sewing machine needle mean?
They're the same size in two systems. The first is the metric size (60 to 120), which SCHMETZ explains is the blade diameter in hundredths of a millimeter, so a size 75 needle is 0.75 mm. The second is the US size (8 to 19). An 80/12 needle is metric 80, US 12. Lower numbers are finer needles.
What size needle should I use for cotton?
For woven cotton, SCHMETZ recommends a Universal needle in 70/10 to 90/14. An 80/12 suits most medium quilting and apparel cotton. Use 70/10 for lighter cottons, and 90/14 for heavier cottons.
What needle should I use for denim?
Use a Jeans (denim) needle. SCHMETZ recommends its Jeans needle in 70/10 to 110/18 for denim, with 90/14 to 110/18 for canvas. For most jeans hems, a 90/14 or 100/16 is a good starting point; go larger for very thick seams. SINGER's equivalent is its Style 2026 Denim/Jeans needle.
What is the difference between a universal and a ball point needle?
A Universal needle has a slightly rounded point that works on wovens and many knits. A ball point (Jersey) needle has a medium ball point that slips between knit fibers instead of piercing them, which prevents runs and skipped stitches on knits. For very stretchy fabrics with elastane, a Stretch needle is better still.
How often should I change my sewing machine needle?
SCHMETZ's rule of thumb is to change the needle after every 8 hours of sewing or after each project, and SINGER says every 8 to 10 hours. Change it right away if you hit a pin, hear a popping sound, or see skipped stitches, shredded thread or snags.
Do all sewing machines use the same needles?
Almost all home sewing machines use the flat-shank 130/705 H system, which SCHMETZ lists as equivalent to 15x1 H and SINGER Style 2020; it's also sold as HAx1. Sergers and some specialty machines use other systems, such as ELx705, so check your manual.
Matching Needles to Your Machine
Your needle can only do so much. For regular denim, canvas or bag-making, a machine with a sturdier frame helps; see our heavy-duty sewing machine picks. If embroidery is your goal, our embroidery sewing machine guide covers combo machines.
