A 110/18 needle is a household sewing machine needle with a blade 1.10 mm thick, numbered 110 in the metric system and 18 in the US system. Choose size by thread thickness and fabric weight; choose type by fabric (Schmetz). Thread pairings are starting points from thread makers; test on a scrap. The sewing machine needle size chart lays all nine household sizes out together.
| Metric / US size | 110 / 18 |
|---|---|
| Blade diameter | about 1.10 mm |
| Fabrics | Heavy canvas, Upholstery, Heavy denim, Leather |
| Thread weights | Heavy and topstitching threads |
| Notes | Schmetz Jeans, Microtex, and Leather come in 110/18. |
The table above sums the size up: a 1.10 mm blade for heavy canvas and similar fabrics, carrying heavy and topstitching threads. Thread and needle are chosen together, so this size runs best with 12 wt thread or 30 wt.

When in doubt, test
Sew a few inches on a scrap of the same fabric, folded to the same thickness. Skipped stitches usually mean the wrong type; shredded thread usually means the eye is too small.
Needles are the cheapest fix in sewing: a pack of 5 costs less than a yard of fabric and lasts 6 to 8 hours of stitching each. Buy them by fabric rather than in bulk in one size, and when the needle is right but the seam still fights you, the machine is the next variable, which is what our best sewing machines for denim roundup digs into.

Frequently asked questions
What is a 110/18 needle used for?
A 110/18 needle suits heavy canvas, upholstery, heavy denim, leather. Schmetz Jeans, Microtex, and Leather come in 110/18. Pair it with Heavy and topstitching threads thread as a starting point, and test on a scrap of your fabric before starting the project.
What do the numbers 110/18 mean on a needle?
The first number is the metric size and the second is the US size. The metric number is the blade diameter in hundredths of a millimeter (80 = 0.80 mm). So a 110 needle has a blade about 1.10 mm thick. Higher numbers are thicker needles for heavier fabric and thread.
What thread goes with a 110/18 needle?
Thread makers suggest Heavy and topstitching threads thread for a 110/18 needle. The eye must let the thread pass without shredding or looping. If thread frays, breaks or skips stitches, move up one needle size or switch to a topstitch or embroidery needle with a larger eye.
Which needle types come in size 110/18?
In Schmetz sizing, 110/18 is available in Universal, Jeans / Denim, Microtex (Sharp), Leather needles. Choose the type by fabric: ballpoint or stretch for knits, jeans for denim, microtex for fine wovens, and universal for general sewing.
Why is my sewing machine skipping stitches?
Skipped stitches almost always mean the wrong needle or a worn one. A universal point can skip on knits where a ball point would not, and a bent or dull needle skips long before it looks damaged, so change it every 6 to 8 hours of sewing. Rethread top and bobbin with the presser foot up, and check the needle is pushed all the way up and facing the right way, as the sewing machine maintenance guide sets out.
What size sewing machine needle should I use for quilting cotton?
Use an 80/12 for piecing quilting cotton with 50 wt thread, and step up to a 90/14 once you are quilting through top, batting and backing. A sharp point, microtex or quilting, keeps the seam accurate on tightly woven cotton. The 80/12 needle page in this section covers the fabrics and threads it handles: an 80/12 needle.
How often should I change a 110/18 needle?
Many sewists change needles every 6 to 8 hours of sewing, or at the start of each new project, and immediately if the needle hits a pin or starts to make a popping sound. A dull needle causes skipped stitches, snags and puckering long before it looks damaged.
