Yarn Weights Explained: From Lace to Super Bulky

Yarn weight determines how soft, strong and drapey your finished object feels. Using the wrong one is the number one reason beginners give up.

The standard scale (US terms)

• Lace – veils, doilies, light shawls (0).
• Fingering – socks, baby garments (1).
• Sport – light sweaters and toys (2).
• DK – the all-rounder: garments, toys, decor (3).
• Worsted – blankets, hats (4).
• Bulky – quick blankets, cushions (5-6).

Hook size matched to weight

Loose DK? Size down. Want airy drape? Size up one hook. Always make a gauge swatch for garments: 4×4 cm or 10×10 cm, count stitches, and compare to the pattern, before starting the full project.

Weight does not equal fibre

Cotton DK behaves nothing like acrylic DK. For amigurumi, tight-stitched cotton or anti-pill acrylic shapes hold best. For blankets, acrylic and chenille feel warmest.

Shop tip: every CrochetMania pattern states yarn weight and hook size on the product page. FAQ explains the chart terms we use.
