Crochet Yarn Calculator

Free crochet yarn calculator: how many yards and skeins you need for any blanket or scarf, by project size, stitch (single crochet to granny), and yarn weight (sock to super bulky).

Estimates assume average tension in the chosen stitch and weight. Tight crocheters, dense borders, and colorwork ends use more — when in doubt, buy one extra skein per color while the dye lot matches.

Why Stitch Choice Changes Everything

Two blankets of identical size can differ by a full bag of yarn purely on stitch choice. Dense stitches like single crochet pack more yarn into every square inch; tall, open stitches like double and treble crochet cover the same area with far less. The factors in this calculator are derived from published per-project yardage data — a 30×36 inch baby blanket takes about 1,242 yards in single crochet but only about 870 in double crochet — and every number on this page is computed from those same factors.

Buying Yarn Like a Pro

Three habits save projects: buy all skeins of a color at once so the dye lots match; keep the receipts — most yarn shops take back unopened skeins; and if the pattern is striped, divide the total by your color count and round each color up. For choosing the colors themselves, the granny square pattern generator previews whole-blanket combinations before you commit a single skein.

Frequently Asked Questions

How much yarn do I need for a crochet blanket?

In worsted weight: a 30×36 inch baby blanket runs roughly 950–1,350 yards depending on stitch, a 48×60 throw 2,300–3,600 yards, and a queen-size blanket 8,000+ yards. Stitch matters as much as size — the calculator prices your exact combination and converts it to skeins.

Which crochet stitch uses the least yarn?

Taller, airier stitches: treble and double crochet use the least (roughly 30–40% less than single crochet for the same blanket), V-stitch and ripple sit close behind, while dense single crochet and moss stitch are the hungriest. The comparison table below shows every stitch priced for the same two blankets.

How many skeins is that?

The calculator divides the yardage by your skein size and rounds up. Type the yards from your yarn label for an exact count — otherwise it assumes a typical skein for the weight (about 200 yd for a standard worsted skein, 130 yd for bulky).

Does yarn weight change how much I need?

Dramatically. Thicker yarn covers area faster: the same throw that needs ~2,700 yards in worsted takes only ~2,000 in bulky and ~1,500 in super bulky — but ~3,000 in DK. The estimates scale with the weight you pick.

How accurate are the estimates?

They are planning numbers with a 10% margin already built in, based on published yardage data at average tension. Your hook size, personal tension, and borders shift the real total — the golden rule stands: buy one extra skein per color while the dye lot still matches.
