How do I increase for amigurumi?

Start with a magic ring of 6 stitches. Round 2: increase in every stitch (12 sts). Round 3: *1 dc, inc* repeat (18 sts). Round 4: *2 dc, inc* repeat (24 sts). Continue adding 6 stitches per round with one more stitch between increases each time.

What size hook for amigurumi?

Use a hook 1-2 sizes smaller than recommended for your yarn weight. This creates a tight fabric that prevents stuffing from showing through. For DK yarn, use a 3.0-3.5mm hook instead of the usual 4mm.

How much yarn do I need for amigurumi?

Small amigurumi (5-10cm) use 20-50m. Medium (10-20cm) use 50-150m. Large (20-30cm) use 150-300m. The tight gauge and 3D construction mean amigurumi use more yarn per unit volume than flat crochet.

How do I make a perfect sphere in crochet?

Increase evenly for the first half (6 stitches per round, spaced evenly). Work several even rounds in the middle to fill out the shape. Then decrease in reverse order. Stuff firmly before closing. The number of even rounds determines how spherical vs oval the shape is.

What is the difference between amigurumi and regular crochet?

Amigurumi uses tighter gauge (smaller hook) to prevent stuffing showing, works in continuous spiral rounds rather than joined rounds, and uses safety eyes or embroidered features. The dc (UK) / sc (US) stitch is standard because it creates the densest fabric.

How We Calculate This

This calculator uses your gauge and target diameter to work out the full amigurumi round schedule.

The formula

Circumference = Diameter x Pi

Max stitches = Circumference (cm) x Stitches per cm

Increase rounds = (Max stitches - Starting ring) / 6

The calculator then generates the full schedule of increase, even, and decrease rounds for your chosen shape.
