How to size a sphere
The stitch count at the equator sets the ball’s size. Work out what you need from your gauge: diameter × stitches-per-inch × 3.14. A 3-inch ball at 5 sts/inch wants about 47 — round to 48. Bigger number, bigger ball; the generator rebuilds the whole pattern instantly, so it costs nothing to compare a 36 and a 42 before you commit.
Both modes start with 6 sc in a magic ring and end with 6 stitches to close. What changes is the path between:
- Classic — the amigurumi standard: add 6 each increase round (6, 12, 18 …), run straight rounds through the middle, mirror the decreases. Predictable, easy to memorize, and what most published patterns assume.
- Smooth — round counts follow a sine curve, so growth is fastest at the poles and gentle near the equator. On balls above ~40 stitches this visibly reduces the “hexagon” look. The transitions land on odd numbers; that’s normal — the even-spacing math handles them.
Reading the pattern table
Every increase round in the table is already evenly spaced — the same math as our increase calculator. Rounds written like *Sc 4, inc* repeat 6 times mean: single crochet 4, two sc in the next stitch, and repeat that block around. Where a round says Sc in each st around, just work even.
Two habits make any sphere pattern look better: stagger the start of each increase round by a couple of stitches so increases don’t stack into a ridge, and stuff the ball firmly a few rounds before closing — under-stuffed spheres wrinkle at the poles.
FAQ
How many stitches should my sphere have at the widest round?
Diameter × stitch gauge × 3.14. Example: 3-inch ball, 5 sts per inch → about 47; enter 48.
Classic vs. smooth — which should I pick?
Small balls (under ~40 sts): classic, matches every published amigurumi pattern. Larger display pieces: smooth reads rounder.
Why do my spheres show a ridge of increases?
Increases stacked at the same position each round. Offset each round’s starting point by a couple of stitches — staggered increases fix it.
When do I stuff the ball?
When the opening is coin-sized — two or three rounds before the end — then close through the front loops with a yarn needle.
