How much yarn do I need for a crochet blanket?

A standard throw (120x150cm) in DK yarn uses approximately 1,500-2,000m. Crochet uses roughly 25% more yarn than knitting for the same area due to taller stitch structure. Chunky yarn blankets use fewer metres but more total weight.

What is the best yarn for crochet blankets?

Acrylic is popular for blankets due to washability and affordability. Cotton is excellent for baby blankets. Wool blends provide warmth. For machine washability, look for superwash wool or acrylic blends. Choose yarn rated for easy care.

How many chains do I need for a blanket?

Multiply your target width by your stitch gauge per cm. For DK yarn at 18 stitches per 10cm (1.8/cm), a 120cm blanket needs about 216 chains plus turning chains. Always make a gauge swatch first.

What is the best stitch for a crochet blanket?

Half treble (UK) / HDC (US) creates a dense, warm fabric. Treble (UK) / DC (US) works up faster but is more open. Granny stitch is a classic choice. Moss stitch creates beautiful texture. Choose based on desired drape and warmth.

How long does it take to crochet a blanket?

A throw-sized blanket in DK typically takes 40-80 hours depending on stitch pattern and your speed. Chunky yarn blankets are much faster (20-40 hours). Working 1-2 hours per day, expect 1-3 months for a full blanket.

How We Calculate This

This calculator estimates yarn for crochet blankets based on dimensions, gauge, and yarn weight. Crochet uses approximately 25% more yarn than knitting for the same area.

The formula

Chain count = Width (cm) x Stitch gauge per cm

Total rows = Length (cm) x Row gauge per cm

Yarn = Area x Grams per cm² x 1.25 (crochet factor) x Metres per gram
