How much yarn do I need for socks?

A standard pair of adult crew socks in fingering weight uses approximately 350-400 metres. Ankle socks use 250-300 metres and knee-high socks need 500-650 metres. Larger shoe sizes and heavier yarn weights need proportionally more.

What yarn weight is best for socks?

Fingering weight (4-ply) is the most popular for socks because it creates a comfortable, durable fabric on 2.25-2.75mm needles. Sock yarn with nylon content (typically 75% wool, 25% nylon) is most hardwearing. Sport and DK weight make thicker, cosier socks.

Should I knit cuff-down or toe-up socks?

Cuff-down is traditional and better for learning. Toe-up lets you try on as you go and use every last metre of yarn, which is ideal for playing yarn chicken or making knee-high socks. Both methods produce identical socks when finished.

What is negative ease for socks?

Socks need negative ease (typically -10% to -15%) so they stretch to fit snugly around the foot. Without negative ease, socks would be baggy and uncomfortable. The knitted fabric stretches to accommodate the foot.

How We Calculate This

This calculator estimates sock yarn based on shoe size foot dimensions, sock type (ankle/crew/knee-high), and yarn weight. It applies negative ease for a proper fit.

The formula

Finished circumference = Foot circumference x (1 + ease%)

Sock length = Foot length + Leg length + Cuff length

Yarn (g) = Circumference x Length x 2 (pair) x Density factor

Yarn (m) = Grams x Metres per gram for yarn weight
