Choosing Sewing Machine Needles: Trying to Understand Needle Type and Size

Feb 13, 2014

We all know the recommendations about sewing machine needles.

  • Change the needle at the beginning of every project or after 8 hours of sewing
  • Use a needle/needle size appropriate for your fabric and thread types
But how many of you have branched beyond the Universal?  Most of the time, when I've come across an article on needles, it goes in one ear and out the other.

Charlie Brown's mom style:  blah, blah, blah...


Until one day, you actually need this information.

And for me, that day came this past month.  I was having trouble with puckering that I'd never experienced before.  I'll admit it - I've sewn for years.... years.... and never really swayed from plowing through everything with a Universal.  Well, except for those "special" projects like hemming jeans with a denim needle.  Because I neither wear heels every day, nor need pants 6" too long. But anyhow...

Frustrated and hungry to solve the problem, I got out my Nancy Drew magnifying glass and started a little research....


Get the point.  The point of the needle varies from a rounded ball to a sharp point.  More rounded needles are used for knits.  Sharp needles are specifically designed for woven fabrics.

Universal needles fall somewhere in the middle of the ball and sharps.  They are often good enough to do the job and work with both knits and woven fabrics - why they are named universal.  Their slight rounded point makes them best for casual sewists who vary the types of fabrics they sew.

But if you are primarily a quilter, best use a needle up to the task.  For piecing with quilting cottons or other high thread count fabrics it is recommended to use sharp (also called microtex) needles.  (from Better Homes and Gardens: Complete Guide to Quilting, 2002)

Quilting needles.  These needles have a tapered shape designed to stitch through may layers and across intersecting seams. Schmetz recommends using their quilting needles for both piecing and quilting.  The finer 75 size is specified for piecing with 50 wt. threads and the 90 size is for quilting with 40 wt threads.

Needle Type should be selected based on the type of fabric (knit, voile, linen, cotton, denim, leather) you are sewing with unless you are adding special embellishments.  Check your users' manual on your sewing machine for needle type/needle size suggestions based on your machine. Schmetz has a good resource on their site to understand the details behind it all - Schmetz Needle Primer.  If you are adding special embellishments to a piece, there are also special needle types to accommodate those specialty threads (i.e. topstitching, metallic, embroidery).

Needle sizing.  Typically defined by two numbers.  The first number is the European size (in millimeters x 100) and the second is the American size.  The lower the number, the finer the needle and the smaller the eye.

Often each needle type is offered in several sizes.
Selecting your needle size should be done in conjunction with the type of thread you plan to use.

For example:

Aurifil recommends using 50 wt thread and mictrotex 80/12 needles.
Gutermann (PDF doc) recommends using Sew-All thread and Universal 70-90 needles.


Are you confused yet?  I think it can be boiled down to this:

1.  Select Needle Type based on your fabric and kind of sewing to be done
2.  Select Needle Size based on your thread

You want to select a needle based on your fabric type with the smallest diameter - to produce the smallest hole - that still accommodates your thread thickness.

I am by no means an expert on this - I simply wanted to share my findings as related to quilting in doing my own research.

Here are some other good reads I found on Sewing Machine Needles -
           Sew Mama Sew - Sewing Machine Needles and How to Choose Them
           Sew 4 Home - How to Choose the Right Machine Needle for the Job
           Craftsy - How to Choose Sewing Machine Needles
           Schmetz Needle Primer

What kind of needles do you use for piecing?  For quilting?

Come back on Monday.  I'll be sharing a new tutorial for keeping track of all these slightly used needles...

  1. There is also some great information on the superior thread site. Also there is a consideration of thread size with ratio and proportion to the eye of the needle. This has to do with the scarf or slot in the needle, and how the width of thread lies and then travels along the edge of the needle with regard to drag caused by our old pal friction. Also gros-Beckett needles are wonderful.

  2. I recently started using a 70/10 needle for quilting with invisible thread, and it is practically eliminated all the breakage that I had before. For everything else I use an universal 90/14.

  3. Of course I just bought a 10 pack of Universal needles. :)

  4. for piecing and quilting i typically use 80/12 universal. but if the batting is thicker or there are a lot of seams, i might switch to 90/14 for quilting. i've used microtex as well but haven't really noticed a difference in stitch quality

  5. Universal, gee, I haven't used those in years and years. I use Schmetz Microtex Sharp size 80 for piecing, to sometimes the Schmetx Jeans/Denim needle, those are good too.

  6. What needle size or you using for the QAL with that pure elements fabric. My fabric looks like it is trying to pucker.

    1. I was using the Universal needle on the Pure Elements fabric with puckering issues. Switching to the Sharp/Microtex needle (80/12) was a HUGE improvement!

  7. *sigh* I don't like the boring technical part of sewing very much... not a direction reader! But that said, I most definitely should pay more attention to my needles and I really appreciate this information you've put together - very useful!

  8. Thank you for such a wonderfully informative breakdown on selecting needles. I have bookmarked this for a quick, go to reminder!
