Whether you’re new to sewing or an experienced seamstress, having the right sewing machine needle is essential for smooth and successful projects. The key is matching the needle size and point style to the type of fabric you’re working with. This guide will walk you through the basics of sewing machine needles so you can determine what needles are best for your next creation.
The Importance of the Right Needle
Using the incorrect needle can lead to skipped stitches, broken threads, snagged fabric, and frustrating experiences. The consequences include wasted time unpicking stitches, potential damage to your sewing machine, and a subpar finished product. Investing the small effort to select needles suited to your fabrics will pay off every time you sit down to sew.
Needle Sizes
The first characteristic to evaluate when choosing a sewing machine needle is the size. Needle sizes range from 60 (thinnest) to 120 (thickest). Most sewing machine needles will be sized 70 to 90 for general garment sewing and quilting. Specialty projects may call for smaller or larger needles. The key things to consider are:
- Weight of fabric – Lightweight fabrics take smaller needles while heavier fabrics need larger needles with bigger shafts. This prevents friction and fabric damage while supporting smooth stitching.
- Type of thread – Match thinner threads to smaller needles and thicker threads to larger needles so the thread moves smoothly through the eye and creates even stitches.
- Type of project – More delicate work demands thinner needles to avoid leaving holes in the fabric. Sturdier projects can utilize thicker needles.
Refer to your pattern or project instructions for the recommended needle size. When in doubt, start in the middle with a size 80 needle which works for most woven fabrics. You can adjust from there if needed.
Needle Point Styles
Beyond the size, sewing machine needles come in an array of point styles. The point is the shape of the needle tip which penetrates the fabric. Selecting a point style aligned with your fabric type leads to better performance through the layers of material. Common options include:
- Sharp – As the name implies, sharp needles have a narrow point to penetrate tightly woven fabrics. They are the most universal needle for sewing with an emphasis on woven fabrics like cotton, silk, and microfibers.
- Ballpoint – Ballpoint needles have rounded points to separate rather than pierce the fibers of knit fabrics. This prevents runs or snags in elastic knits like jersey, fleece, interlock, spandex, and sweater knits.
- Stretch – Stretch needles combine a slight ballpoint with a stronger shaft for sewing sturdy stretch fabrics without skipped stitches, such as swimwear, activewear, fleece, vinyl, and synthetic suedes and leathers.
- Embroidery/Crewel – These needles have a special scarf (groove above the eye) to prevent fraying and shredding of embroidery floss. Use them for embroidery, crewel work, and sewing with delicate metallic threads.
- Leather – Leather project call for a wedge-shaped point and cutting blade to make clean holes in leather without leaving permanent marks.
- Denim/Jeans – The thick shaft and extremely sharp point of denim needles push easily through multiple layers of heavy fabrics like denim and canvas without deflecting.
If your fabric type doesn’t align with a standard specialty needle, start with sharp needles as the most versatile option. Pay attention as you sew and adjust to a different point style if you experience skipped stitches, breakage, or snags. Checking that you have the best needle for your supplies will solve the majority of sewing headaches.
Fabric and Needle Pairings
To simplify the process of selecting needles, refer to fabric-needle pairing guides. Keep the list handy by your sewing machine for quick reference before starting a project with unfamiliar or tricky materials. Some of the most common pairings include:
- Woven cotton – Sharp 70/80
- Woven silk – Sharp 60/70
- Knit jersey – Ballpoint 75/90
- Double knit – Ballpoint 75/90
- Fleece – Stretch 75/90
- Denim – Denim 90/100
- Leather/Vinyl – Leather 90/100
- Batik – Sharp 75/90
- Quilting cotton – Sharp 75/80
- Embroidery – Embroidery 75/80
Don’t be afraid to experiment with different needle sizes and points if your fabric calls for it. Sew a few testing lines before starting a major project to ensure even stitches without damage to the material.
When to Change Your Needle
As you accumulate projects, pay attention to potential signs it’s time to insert a fresh needle:
- Skipped stitches
- Broken threads
- Snags or runs in fabric
- Visible scratches or burrs on needle
- Difficulty penetrating fabric
- Looping or poor stitch formation
Ideally, needles should be changed every 6-8 hours of sewing or after finishing a large project like a quilt. Planning ahead to have replacement needles on hand saves headaches when your current needle starts to underperform.
For less than $10, you can purchase variety packs with multiple sizes and types to have every needle at the ready. Organize your needles by project type or fabric so replacing a dull needle takes no time at all, avoiding sewing frustration. Keeping fresh sewing machine needles primed for action is one of the easiest ways to set your sewing up for success.
How to Read a Needle Packet
When purchasing needles, you’ll encounter a range of numbering and sizing systems which can cause confusion in selecting the correct option. Here’s what the key markings mean:
- Size – This refers to the needle thickness using standard numbering (60 to 120 as discussed above). Match it to your thread and fabric weight.
- Point style – Abbreviations like SPI (sharp), SUK (ballpoint), LL (stretch), and DEM (denim) identify the needle point. Choose what’s recommended for your fabric type.
- Shaft length – The shaft is the portion above the eye which inserts into the needle clamp. Standard lengths include:
- Short (13mm) – For household machines
- Regular/Average (20mm) – For most sewing machines
- Long (25mm) – Specialty machines like tall commercial or embroidery models
Reading needle packets carefully ensures you purchase correctly. If unsure, bring fabric swatches to test needles in store under employee guidance.
