Scarf Yarn Calculator

Plan your scarf from yarn to finished length. Pick a style to load typical dimensions and a suggested yarn weight, or set your own — then see yardage, skeins, and how long it will actually be. Working from a stash? Use the one-skein planner below to find out what you can make.

Estimate for a 60 × 8 in worsted-weight scarf. Skein counts assume a typical worsted skein (200 yds) — check your yarn’s label, as yards per skein vary by brand.

One-skein planner: what can I make?

Have yarn already and want to know what fits? Enter how many yards you have and how wide you want it — this estimates the scarf length you can reach. One worsted skein is often about 200 yds.

Frequently asked questions

How much yarn do I need for a scarf?

A classic worsted-weight scarf (about 60 × 8 in) usually needs 300–500 yards. Skinny scarves use less; wide wraps use considerably more.

Can I make a scarf with one skein?

Often yes. One worsted skein (about 200 yards) can make a skinny scarf or a generous cowl — roughly 40 in long at 6 in wide. Use the one-skein planner above to check your exact yarn.

How much yarn for an infinity scarf?

An infinity scarf is a closed loop, so it uses a bit more than a flat scarf of the same width — commonly 250–450 yards in worsted weight.

What is the best yarn for a scarf?

Wool is warm and structured; alpaca and mohair are soft and drapey; cotton is light and cool; acrylic is budget-friendly and easy to wash. Pick by the drape and warmth you want.

Knit or crochet — which uses more yarn?

Crochet generally uses about 25–35% more yarn than knitting for a comparable scarf. Select crochet above to add roughly 30%.
