Make a Crochet Sphere in Any Size

Sharing is caring!

As the name implies, a crochet sphere is a ball created with the Amigurumi technique. In this article, I’ll show you the secret to making a perfectly symmetrical crochet ball with single crochet stitches in continuous rounds. 

Once you figure out the simple formula to crochet a sphere, you can crochet balls that can be incorporated into many patterns for 3D projects. You can use them to make bodies for crochet animals, toy balls for kids and pets, beads for jewelry (using thread), stress balls, and even ornaments in general.

 Additionally, due to their simple shape, they can be fun projects for beginners trying to learn Amigurumi. Keep scrolling for the full instructions, but let’s start with some helpful information to set you up for success.

Creating a Symmetrical Crochet Sphere 

You will create a symmetrical sphere in three sections: one to increase, one of plain rounds, and a third to decrease. A perfectly shaped ball will have the same circumference when measured from any direction across the center.

If you want to explore a sphere’s general geometric details and anatomy in more depth, Cuemath has an article here. But I am trying to show you here that the ratio approach is different with a crocheted sphere.

Did you know? The stitch multiples and the number of rounds used must be in a particular ratio to create a constant circumference at all angles. 

Crochet Sphere

How does it work?

Section #1 includes a magic circle and continuous rounds of single crochet stitches with increases. The spiral stitching technique and the increases will determine the ratio to make the ball as large as you like.

Section #2 is made of plain rounds of crochet stitches (no increases or decreases). This is where the secret to the “perfect crochet sphere shape” lies. If you add too few or too many rounds, your sphere will look asymmetrical, too short, or too tall. More on this below.

Finally, section #3 has the same ratio of rounds and stitches as section 1. But here, you will decrease to close the sphere.

How Many Rounds to Crochet

The instructions in this article include the numbers for three different stitch multiples. However, finding out how many rounds are needed for a crochet sphere is easy. You will crochet the increasing rounds and take some measurements as you go. (I’ve tried it, and I can tell you… it works!).

Adjusting the Ratio:

If you’re like me, geometry was one of my least favorite subjects at school. But you don’t have to remember those days, I promise! Here is a simplified way to find out how many rounds you need:

  1. First, you crochet section #1 of the sphere, starting with 6, 7, or 8 stitches in a magic ring. Use as many increasing rounds as needed for the circumference you’re looking for.
  2. Next, count the increased rounds and add at least half of that number in plain rounds for section #2. So, let’s say you made six increasing rounds for the first section, and then you’ll need to add 3 or 4 plain rounds.
  3. Then, with a flexible measuring tape, measure the circumference of that half sphere’s open part (see photo #1). Imagine you got 8” (20 cm). You now divide that number by 2 = 4” (10 cm).
  4. Now, measure the half circumference of the half-made sphere at the opposite angle across the center (see photo #2). That number must be the result you got in the previous step: 4” (10 cm), or at least close enough. Add more rounds if that number is much smaller or frog if it comes up much larger.
  5. Lastly, count how many rounds you had for the first half of the sphere and use that number to make the other half (see photo #3). For example, if you had 10 rounds (6 increasing and 4 plain rounds). Then, you will need 4 more plain and 6 decreasing rounds for the second half.

Crochet Sphere Pattern

The Basic Steps

  • Create a pattern that consists of even multiples of stitches in increasing, plain, and decreasing rounds
  • To start, create a magic circle and work single crochet stitches in continuous rounds with increases for the first section of the sphere. 
  • The second section should consist of plain rounds of crochet stitches with no increases or decreases. 
  • Measure the circumference of the half sphere across the starting center. Then, use that number to adjust the number of plain rounds needed for the second section (more on the “adjust the ratio” above). 
  • For the third section, use the same ratio of rounds and stitches as the first section, but decrease to close the sphere
  • Stuff the sphere when it is about ¾ of the way done, adding more fiber as needed. Finish off and weave in all left ends. 

Overall Notes 

This pattern uses US Crochet Terminology.

Level of difficulty: Easy.

Finished Size: the finished sphere circumference will be approximately 8.5” (21 cm) for the small size, 9” (23 cm) for the medium, and 10.5” (26 cm) for the large.

Helpful tips:

  • Use a stitch marker to mark each round’s first or last stitch, moving it up as you go. This is the best way to keep track of your stitch count and rounds.
  • Stuff the sphere when it is about ¾ of the way done, adding more fiber as you go. But be careful not to overstuff it.
  • I’ll give instructions for multiples of 6, 7, or 8 stitches for this crochet sphere. The ratio concept to make it symmetrical will be the same for all multiples. See the details of the “Adjust the Ratio” section above.
  • I do not recommend starting the ball with less than 6 stitches in the magic circle; otherwise, it will be too pointy. And no more than 8 stitches; it will be too flat and require too many plain rounds to fix the ratio. 
  • As an alternative to the magic circle, you can start the sphere with two chains and crochet round 1 in the 2nd chain from the hook.

Crochet Sphere

Step 1: Make section #1 

Tip: To make your sphere larger, continue increasing rounds with the chosen multiples (6, 7, or 8 sts), one increase in each multiple. 

Small Crochet Sphere: 

Rnd1: sc 6 in a magic circle

Rnd2: (inc) x 6 [12]

Rnd3: (inc, sc in next st) x 6 [18]

Rnd4: (inc, sc in next 2 sts) x 6 [24]

Rnd5: (inc, sc in next 3 sts) x 6 [30]

Rnd6: (inc, sc in next 4 sts) x 6 [36]

Go to step 2.

Medium Sphere:

Rnd1: sc 7 in a magic circle

Rnd2: (inc) x7 [14]

Rnd3: (inc, sc in next st) x 7 [21]

Rnd4: (inc, sc in next 2 sts) x 7 [28]

Rnd5: (inc, sc in next 3 sts) x 7 [35]

Rnd6: (inc, sc in next 4 sts) x 7 [42]

Go to step 2.

Large Crochet Sphere

Rnd1: sc 8 in a magic circle

Tips added to the two previous instructions apply to this option as well.

Rnd2: (inc) x 8 [16]

Rnd3: (inc, sc in next st) x 8 [24]

Rnd4: (inc, sc in next 2 sts) x 8 [32]

Rnd5: (inc, sc in next 3 sts) x 8 [40]

Rnd6: (inc, sc in next 4 sts) x 8 [48]

Go to step 2.

If you want your crochet sphere larger, keep increasing in multiples of 6, 7, or 8 here. See the section “Adjust the Ratio” above for the details.  

Step 2: Make the Middle section

This is the section where you add plain rounds to create the middle section of your crochet sphere. If you add extra increasing rounds in the previous steps, you will need to add extra plain rounds here as well.

Small Sphere:

  • Rnd7-14: sc around [36]
  • Go to step 3.

Medium Sphere:

  • Rnd7-15: sc around [42]
  • Go to step 3.

Large Sphere:

  • Rnd7-17: sc around [48]
  • Go to step 3.

Step #3: Make Section 3

Tip: Add stuffing fiber when you have 2 or 3 rounds left to finish. To avoid bumps and make your sphere smooth, add as much fiber as possible at once and cut a slit in the center of the fiber if you need extra stuffing. 

Small Crochet Sphere:

Rnd15: (dec, sc in next 4 sts) x 6 [30]

Rnd16: (dec, sc in next 3 sts) x 6 [24]

Rnd17: (dec, sc in next 2 sts) x 6 [18]

Rnd18: (dec, sc in next st) x 6 [12]

Rnd19: (dec) x 6 [6]

Cut the yarn, leaving a long tail.

Medium Crochet Sphere:

Rnd16: (dec, sc in next 4 sts) x 7 [35]

Rnd17: (dec, sc in next 3 sts) x 7 [28]

Rnd18: (dec, sc in next 2 sts) x 7 [21]

Tip: This is a perfect time to add stuffing fiber. 

Rnd19: (dec, sc in next st) x 7 [14]

Rnd20: (dec) x 7 [7]

Cut the yarn, leaving a long tail.

Large Crochet Sphere:

Rnd18: (dec, sc in next 4 sts) x 8 [40]

Rnd19: (dec, sc in next 3 sts) x 8 [32]

Rnd20: (dec, sc in next 2 sts) x 8 [24]

Add stuffing fiber.

Rnd21: (dec, sc in next st) x 8 [16]

Rnd22: (dec) x 8 [8]

Cut the yarn, leaving a long tail.

Step 4: Finish Off

Pull the cut tail through the last st so it doesn’t unravel. Then, thread a tapestry needle with that tail and whip st in the flo of each st individually, then pull it tight to cinch. FO. Weave in the ends.

In Conclusion

As you can tell by the photos of all three crochet spheres in this article, either 6, 7, or 8-stitch multiples will create a symmetrical ball. But if you’re still wondering which one to choose, consider the sphere size you want. 

6 stitches in the initial round will make it smaller, and 8 stitches will make it larger without adding too many increasing rounds. Regardless of your chosen option, the result will be a perfectly shaped crochet ball.
