Knitting in the Round: Fixed Circular vs. Double-Pointed Needles

If you’re new to knitting, the vast selection of knitting needles probably gives you a headache. Straight needles are easy enough to understand, but things get complicated when you start knitting in the round with fixed circulars, double-pointed needles, or both!

No need to cry when you shop the knitting needle section. Here are a few ways to know when you should use fixed circular needles and when you should use double-pointed needles.

When to use double-pointed needles

Stefanie Japel’s Trendy Headband from her Knit Lab: In the Round class is a great (and pretty!) example of a project that uses double-pointed needles. Double-pointed needles are perfect for smaller knitted projects, like fingerless gloves, that won’t fit on circular needles. The smallest fixed circular needle available is 16″ in circumference. Taking into consideration that you want your needle circumference to be slightly smaller than your project’s finished circumference, anything you knit that’s less than about 16″ in circumference will need to be knitted on double-pointed needles.

When to use fixed circular needles

You know one thing that’s so awesome about circular needles? You don’t have to knit in the round to use them! Don’t tell straight needles I told you this, but you could use fixed circular needles for the majority of your knitting projects if you wanted to. In fact, I prefer circular needles for heavier garments, like shawls, because they make it much easier on your wrists when holding the weight of the project.

But of course, circular needles are also fantastic for in-the-round projects. Some knitters prefer circular needles to double-pointed needles because they’re a little easier to hang onto. Plus, your work doesn’t slide off a circular needle quite as easily as it might a double-pointed needle. (I’m a fan of circulars. Can you tell?) To read more about what circular needle lengths are best for which projects (yes, even projects that are knit flat!), check out our guide to circular knitting needles.

Transitioning between circulars and DPNs

Sometimes a project requires you to have both circular and double-pointed needles. This is because as the circumference of the project changes, you’ll need a smaller needle. If it’s a larger project, like a poncho, the pattern might just ask you to change from a 36″ circular to a 24″ circular as the poncho decreases in circumference. For something like Stefanie Japel’s Sawtooth Hat above, you’d begin knitting the bottom with a 16″ circular needle, then change to double-pointed needles when you start decreasing the crown. That’s because the hat is becoming so small that fitting all those stitches on a circular needle would be impossible!

Hello. Good article. I find it easier to knit on DPs because I have nerve damage in my left fingers and find circulars difficult. I want to knit a slouchy hat. The pattern starts with circulars and then switches to DPs. Is it possible to do the entire hat with DPs? I knit socks often, so I am used to DPS. Thank you for your advice. Hope all is well.

I am looking to do the same. I have inherited so many needles and don’t want to buy more. If I have the right size in dpn I’d rather try that for MY slouchy hat. I hope it goes well with you 🙂


Maybe because I’m English I much much prefer straight needles. Hate DPN and circular. Drives me CRAZY how many US patterns call for circular needles when straight will do!!!!


If a pattern is written for straight needles, do I need to change it if I use circular needles? Or if the pattern just specifies the size of the needles to use, and it has a large cast on as for a baby blanket, 100 or so stitches, is it safe to assume it is written for circular needles?

In other words, when does a pattern need to be changed or altered? Magic loop? Circular? Straight?


I am wondering if you started v a hat with a US9 circular, and it says to change to dps when needed. Do the dps need to be the same size or could I use a US6?
