A Guide to Circular Knitting Needles

Posted by on Sep 4, 2013 in Knitting | Comments


The circular-knitting needle section of your local yarn or craft store can be a bit overwhelming. Even though I’ve been knitting for many years, I still space out a little when I walk into the needle aisle and see all the choices.

If you’re new to knitting, you probably ask yourself, why all the different lengths and why in the world would I need a 36″ needle?

Often, your pattern will tell you what type of needle you need, but what if you’re designing something yourself? Don’t let the name “circular” fool you. Even though they’re called circular needles, you won’t just need them when you’re knitting in the round.

Use this guide next time you shop for circular needles and breathe a little easier when you’re faced with all the options.

36″ circular needles

Good for: heavy or large projects that will be knitted flat.

Have you ever tried to knit a heavy project, like a shawl, on straight needles? The wrist pain is unbelievable. I made this mistake early on in my knitting career and ended up having to hunch over my knitting so that the table held most of the weight. You can bet I never made that mistake again!

You may also need to use a circular needle if each row has a large number of stitches. Straight needles have a limited amount of space on them, so casting on 300 stitches is probably going to be impossible, even if you’re using a long straight needle.

Using a long circular needle, like the 36″ one, will put all the weight of the project onto the cord, allowing you to speed along as you knit. The majority of the weight can rest in your lap or on the table while you knit.

The Watercolor Ponies Poncho, seen above, is one example of a project that’s great for 36″ circular needles because each row has a lot of stitches. Any garment that’s loose-fitting, like ponchos and shawls, will call for a longer circular needle.

29″ circular needles

Good for: medium-sized projects knitted flat, like the Iris Pi Shawl seen above.

Like the 36″ circular needle, the 29″ needle can be used for projects that are knitted flat. The difference is that the 29″ can be used for a project that’s just a bit smaller in size.

16″ circular needles

Good for: small projects knit in a tube.

If you’ve ever followed a pattern for a hat, you’ve probably used a 16″ circular needle. These needles are perfect when the project is just a bit too large to fit on double-pointed needles. The Purl Turban Headband, seen above, is a great example of when a 16″ circular needle will come in handy.

Unlike the 36″ and 29″ needles, the 16″ needle is used more often for knitting in the round. Hat patterns will often ask knitters to use a 16″ to work the brim, then switch to double-pointed needles as the hat gets smaller at the crown.

    Nobody knits with straights anymore. My local yarn shop doesn’t even sell them.

    I hate straight needles, They kill my hands, but I found a great use for my old straight needles. Gave them to my dog show friends who use them to part coats on Lhasa Apsos, Tibetan Terriers, and Skye Terriers to name a few.

  3. Ruth Haydon says:

    I must be nobody, because I knit with straight needles quite often. They are great for small items like scarfs. I use circular needles when I have a large number of stitches or am knitting in the round. I use double pointed for hats and socks.

    1. Natalie says:

      I guess I am a “nobody” as well. I also love my straight needles for making small projects like cup cozies, scarves, and etc. I use circular and DPN’s as well but I think all of them have a purpose.

      1. Miss Cara says:

        People have been knitting with straight needles for a longer time than circular. I use straights all the time as my first preference if possible and I use straight double pointed needles to do circular knitting. For example, a slipper that uses several short rows cannot handle a circular needle because the turns are too sharp and it bends the cord to almost snap. Also, circulars can waste time since they seem to loosen and I’ve lost stitches this way….and, some yarns snag too, making obvious marks! I think straight needles have it’s place, but hardly are they on the level of parting animal hair for their only utility.

  4. colleen says:

    I would not be able to knit if it weren’t for circulars My hands could never take it.

  5. Diane Addams says:

    Contrary to popular belief, there are people who still use straight needles and they still make and sell them….true they aren’t as popular as in times gone buy, but they are very useful for small projects with a small amount of stitches. As a matter of fact, I currently have 47 stitches on a set of straight needles…I ‘m making square for a baby blanket!

  6. Lynn says:

    I’ve thrown out my old straight needles — can’t imagine ever using them again. Well — maybe when I teach someone how to knit….

    It would be helpful to have reviews of the various brands of circs — especially the ones with replaceable tips.

    1. Scarlett007 says:

      You no doubt know this, still, please check out Knit Picks.com! They sell all kind of needles, singly & in sets. I think (maybe) that I’ve seen what you are wishing for over there! They can, at least, get you started. GOOD LUCK*!*

  7. Joan Archer says:

    I’m finding I prefer to use circulars now for knitting even when the piece is flat. I mainly use Interchangeable needles so depending on the number I can pick different size cords.
    I do still use straights on the odd occasion in fact the project I’m knitting at present has a separate front lace border that’s stitched on after and I’m knitting that on 8” straights there’s 21 stitches for it.

  8. Tamara says:

    I’m wondering about the sizes that I usually see in the stores: 40″, 32″ and 24″. Do you have different size needles in your stores than we do here in VT??

  9. herdewerknotty says:

    Using a cross between irish cottage and continental style knitting, I find long straights to be much faster then circular needles which is especially nice when working on big projects because you finish them sooner, but I do agree the weight can be tremendous.

  10. Sharon says:

    I want to make a knitted cap for my grandaughter, the instructions say to use 5 dpns. Could I use circular needles to knit this as long as I use a row start stop marker. I’m new to knitting and just wondering. It seems to be much easier.

  11. I saw someone using circular needles that were for a very small item 3 inches round. Need smaller tips and lengths for hats so I don’t have to use double points for binding off, Where can I get them.
