To make sure we’re covering all the basics, we’ll start with the anatomy of sewing machine needles, the different types and sizes of needles, and when and how to use them. Disclaimer: This post might contain some affiliate links, you can find my full Disclosure Policy here.
Anatomy of a Sewing Machine Needle
Before we jump into the nitty-gritty of different types of sewing machine needle sizes, let’s take a look at the anatomy of a machine needle. A sewing machine needle has several parts:
Eye: the aperture where the thread will go through. The eye size varies depending on the needle type. Point: refers to the tip of the needle, and it varies depending on the type of needle. Scarf: this is the indentation just above the eye of the needle on the back. It enables the bobbin thread to pass near the needle eye, catching the needle thread, thus creating a stitch. Shaft: the area between the scarf and the shank. The shaft varies in thickness according to the needle type. Shank: this is the part that goes into the machine. It has a flat side that makes it easier to insert into your machine.
Choosing the Right Sewing Machine Needles
Choosing a needle is an important part of the sewing process, and there are different types and sizes of needles for different fabric types, fabric weights, and thread types. To ensure you have the right needle for your project, consider the following steps:
Fabric Type
To ensure that your project is a success, you need to make sure you’re choosing the right needle for the type of fabric you’ll be sewing. For woven fabrics, you can use universal, jeans, or sharps/microtex needles. Ballpoint or jersey needles can be used for sewing knit fabrics, while stretch needles should be used for stretch fabrics, and a special leather needle should be used for leather.
Fabric Weight
Once you decided which fabric type you’ll be sewing, another factor to consider when choosing the sewing machine needle is the fabric weight. Making the wrong selection can lead to the breaking of your needle. Fabrics come in various weights, from sheer and lightweight fabrics like chiffon, silk, and organza to thicker, heavier fabrics like denim, canvas, and upholstery fabrics.
Thread Type
When selecting the right needle for your project, consider the type of thread you are using. Choose a needle with an eye large enough to fit the thread diameter. For example, topstitching thread is much thicker than regular sewing thread, so you will need a needle with a bigger eye to accommodate the thread weight. When working with embroidery thread you will also need a special needle with a bigger eye and rounded point to guard against excess friction.
What Do the Numbers Mean on Sewing Machine Needles?
When you buy a package of needles, you will notice a bunch of numbers on it. You may have wondered what these numbers mean. Here’s an example from the Singer brand:
Sewing Machine Needle Types
When picking out a sewing machine needle for your project, it’s essential you think about the type of needle you need before checking its size. Certain fabrics require special types of needles. Here’s a list of the different types of sewing machine needles and when to use them:
Universal Needles
Universal needles are used for woven fabrics. These needles are suitable for any home sewing machine and they come in different sizes, each suitable for different fabric weights.
Ball Point (Jersey)
Ball Point or jersey needles are used for sewing knit fabrics. They have a rounded tip that prevents damage to the fabric when passing through the thread.
Stretch needles
Stretch needles are used for stretch fabrics such as lycra or spandex.
Jeans (Denim)
Jeans needles also referred to as denim needles, are suitable for sewing denim, jeans, and canvas.
Leather needles
Leather needles are designed specifically for leather and vinyl. The pointed end is sharpened to easily pierce the material and form stitches.
Topstitch needles
Topstitch needles are specially designed for sewing with thicker threads. They have a larger eye and a stronger shaft to support the thicker thread.
Embroidery needles
Embroidery needles are used for sewing with embroidery thread. They have a protective scarf to protect the thread and a bigger eye for threading.
Quilting needles
Quilting needles are designed for stitching through multiple sheets of fabric. They have a strong shaft and a sharp point.
Twin needles
Twin needles create two rows of stitches simultaneously and are used for topstitching. There are different types of twin needles – universal twin, twin stretch, and twin denim.
Sewing Machine Needle Sizes
After you’ve determined the right type of needle for your project, the next step is to select the proper size. The American system is numbered from 8 to 18, with the lower numbers being finer needles, and the higher numbers being larger needles. The European system is numbered from 60 to 110, and the same logic applies. Most brands of needles are featuring both American and European sizing numbers on the package. If you’re a beginner sewer, use the sewing machine needle sizes guide below: REMEMBER: the lighter the fabric the smaller the needle size and the heavier the fabric the larger the needle size.
How Often Should I Change My Needle?
Ideally, you’ll want to use a fresh needle every time you start a new project. The average lifespan of a sewing needle is between 6-10 hours, depending on the thickness of the fabric you’re using.
