How a crochet sphere works
Almost every amigurumi ball follows the same recipe. You start with 6 stitches in a magic ring and add 6 stitches every round, which makes a flat circle that cups into a dome. Once the widest round is big enough, you work a few rounds without increasing to build the sides, then decrease 6 stitches every round to close it.
The widest round sets the size. With 5 stitches per inch, a 36-stitch round makes a ball about 2.3 inches across, because the circumference is π × diameter.
Abbreviations
- sc: single crochet
- inc: 2 sc in the same stitch
- dec: single crochet 2 together (invisible decrease recommended)
- (36): stitch count at the end of the round
Frequently asked questions
How do I make my amigurumi ball rounder?
Keep the "stagger" option on so increases don't stack up and form corners, and use the invisible decrease. Stuffing firmly and evenly also makes a big difference.
How do I measure gauge for amigurumi?
Crochet a small flat piece in single crochet with your yarn and hook, then count how many stitches and how many rows fit in one inch or centimetre.
Can I use this for an oval or egg shape?
Yes: generate a sphere, then add extra even rounds in the middle to make it longer.
