Are you wondering what size sewing machine needle for denim? You’ve been sewing for a while and have a good idea of the different needle types. But do you know which is best for denim?

Needles are an essential part of any sewing project. They can make or break your final product. Whether you’re working with heavy-duty materials like denim, leather, or delicate fabrics like silk, it’s essential to use the right one.

This blog post will provide the information you need to know about selecting the right sewing machine needle size for sewing denim.

The first thing that you need to do before starting any project is read through all of the instructions on how to thread and use your sewing machine properly, including what type of stitch pattern to use, which type of fabric it should be used, and the best heavy duty sewing machine.

You can’t just pick out a needle without considering these factors because they all play an essential role in determining which one will work best.


What Size Sewing Machine Needle For A Denim

So, what size sewing machine needle for denim? A size 100/16 needles should do the trick for most thick denim fabrics. But the perfect sewing machine needle size for denim will depend on the thickness and weight of your fabric. You should look for a sewing machine needle appropriate for your fabric.

A universal 100/16 or 110/18 sewing machine needle will be suitable for most denim types. But if you’re sewing a thicker denim fabric, the best needle size for denim is a jeans/denim needle-sized 90/14, 100/16, or 110/18, which has an even larger eye and a sharper point. You want to use a sharp needle with an extra-large eye so the thread can easily pass through.

Because these needles are sharp, they will pass through the fabric more easily. Since the needle holes are more significant, your thread will handle better. A denim needle is designed for heavyweight fabrics, while a standard needle is better suited for lighter materials.

If you are unsure which needle to use, start with a universal needle and switch to a jeans needle if you find it too difficult to pass the needle through the fabric, which means fewer skipped stitches and needle breaks.

A general guideline for choosing a needle size is as follows:

  • Thin fabrics: Use a size 70/10 needle.
  • Medium fabrics: Use a size 80/12 needle.
  • Medium Heavy-weight fabrics: Use a size 90/14 needle.
  • Heavy-weight fabrics: Use a size 100/16 needles.
  • Extra-heavy fabrics: Use size 110/18 needle


Factors To Consider When Choosing A Sewing Machine Needle Size For Denim

There are some things that you should keep in mind when choosing a sewing machine needle size for denim:

  • The needle you choose should be sharp and have an extra-large eye to pass the thread through easily.
  • A universal or ballpoint needle is perfect for this type of fabric, as they’re designed specifically for woven materials.
  • Before starting any project, you should always read through all the instructions on threading correctly and using your sewing machine.
  • Consider the fabric type, stitch pattern, and other factors before selecting a needle size.
  • Your machine should be able to stitch through 5 layers of fabric at 2 mm; otherwise, you will just get puckers on the inside.
  • Depending on how heavy your denim is, you may need a thicker or longer needle. The most significant risk for breaking needles while sewing jeans comes from the thickness of the fabric and how thin the needle is.
  • If your denim is heavy, then you may need a thicker needle size, such as jeans/denim or heavy-duty.
  • When selecting a sewing machine needle, always choose the sharpest one available. A dull needle can cause your fabric to pucker and lead to skipped stitches.
  • In this case, you will also have to use a longer needle because the point of a short needle won’t be able to go through all those layers.
