Creating a perfect circle in single crochet seems to mystify a lot of people. But it really shouldn’t. Crocheting a flat circle of any size can be done with the help of a very simple and predictable formula.—Note how I avoided using the word math. Yes, it is math, but that doesn’t mean it should scare you.—So for those of you who like having these sorts of things in writing here’s the formula for a single crochet flat circle:

You may choose to join rnds or work in a continuous spiral as it makes no difference to the formula. Make an adjustable ring (magic loop) and work Rnd 1 into it. Or Ch 2 and work Rnd 1 into the 2nd ch from hook.

Rnd 1: 6 sc in ring. —6 sts
Rnd 2: 2 sc into each st around —12 sts
Rnd 3: (Sc in next st, 2 sc in next st) around —18 sts
Rnd 4: (Sc in next 2 sts, 2 sc in next st) around —24 sts
Rnd 5: (Sc in next 3 sts, 2 sc in next st) around —30 sts
Rnd 6: (Sc in next 4 sts, 2 sc in next st) around —36 sts

Let’s analyse this formula…

With every round completed, you are adding a total of 6 additional stitches. This also happens to be the number of stitches you had in rnd 1—meaning that your increase multiple is 6 in each round.

There is also a highly predictable pattern to the stitches in each rnd. In Rnd 1 there are no increases (2 sc in next st), Rnd 2 is only increases, Rnd 3 has one before the increase, Rnd 4 has two before the increase, Rnd 5 has three before the increase, and Rnd 6 has four before the increase. As you can see, each rnd has an extra none-increase stitch added before the increase. Simple!

If words aren’t your thing, then take a look at my video tutorial showing how to crochet this perfect single crochet circle.

Hope that helps!

Comments & Questions from the Nattypat Community

Nattypat Crochet: Yes this is an alternate method which many people also like as it distributes the stitches around the circle evenly without having them always occurring at the same location. Thanks for commenting!

Nattypat Crochet: Hi Patsy! It’s a predictable pattern for increasing stitches to create the circle. With each round, you simply need to add more additional stitch before you complete the actual increase.

Nattypat Crochet: Hi Darcy! For those who work tight, sometimes it’s advisable to use a larger hook to try to compensate and have the stitches turn out looser, thereby avoiding the curling. However, if you follow the same basic increasing pattern in indicated but start with an extra number of stitches, this may work best in your case. Just start with any number of stitches in the first round to have it lay flat (this should be more than what was indicated). Let me know how that goes!

Nattypat Crochet: Sorry for the very late reply! Look’s like your post snuck away from me. You are correct, when you work with taller stitches you do need to work a little differently. In general, as the stitches get taller, the more stitches you need to have in your beginning round. You still use the same increase pattern, but you need to start with more in the beginning to allow the work to lay flat.

Nattypat Crochet: Glad it helps Mary :). May there be no more unintentional beanies in your world!

Nattypat Crochet: Hi Lindie. It may be that you are working either 1) too tightly, 2) using the a hook that is too small, or 3) both. If you are working with a tall stitch, such as a double crochet or a treble (triple) crochet, you also need to add more initial stitches to your first round to allow it to lay flat. For a double crochet circle, you should have 16 double crochet stitches in the first round.

Nattypat Crochet: Yes, I know what you mean. Most circles have an increase of 6 stitches each round. This means that the completed circle has 6 corners, making it a subtle hexagon (it’s not a full hexagon because you don’t add extra stitches to create the corner as you would in a granny hexagon for example). I’ve found that the best way to minimize the subtle hexagon is to add a final border of single crochet (sc) around the circle. Work one sc into each stitch around. To be fancy, you could also do a reverse sc (crab stitch) around. Ultimately crochet is based in math and consistent increases so the subtle hexagon will always be there.

Nattypat Crochet: That absolutely does work, good point! It’s never too late to write a good comment on a post :). Thanks!
