How Much Yarn Do I Need for a Crochet Blanket? (Size Chart)

Quick answer: the yardage chart

These amounts are for a worsted weight (category 4) blanket in a medium-density textured stitch, like our ridge texture throw. Your exact number depends on the four factors below — which is why good patterns list yardage per size instead of guessing.

• Baby Lovey (30×36") — roughly 150–180 m (165–200 yards)
• Lap Throw (40×50") — roughly 230–260 m (250–285 yards)
• Twin Bed (50×66") — roughly 350–400 m (385–440 yards)
• Full Bed (60×76") — roughly 480–530 m (525–580 yards)
• Queen Bed (65×89") — roughly 610–670 m (665–735 yards)
• King Bed (75×86") — roughly 680–750 m (745–820 yards)
• Giant Throw (80×99") — roughly 830–920 m (910–1005 yards)
• Deluxe King (90×96") — roughly 900–1000 m (985–1095 yards)

Factor 1: stitch density

Dense, textured stitches (alpine, bobble, waffle) eat 15–30% more yarn than open stitches (granny, filet, lace) for the same blanket size. Post stitches literally fold extra yarn into the fabric — that's where the cozy thickness comes from.

Factor 2: yarn weight and hook size

Bulky #5 yarn with an 8 mm hook covers area much faster than worsted #4 on 5.5 mm — fewer stitches per square inch means fewer total meters, though each meter is heavier. If you want a fast blanket that drinks less yardage, chunky yarn with a bobble or ridge pattern is the shortcut.

Factor 3: your personal tension

Two crocheters following the same pattern can differ by a full skein over a throw-sized blanket. This is why gauge matters: check your stitches-per-10cm against the pattern before you buy all your yarn, and buy one extra skein of the same dye lot as insurance.

Factor 4: borders and extras

A simple single-crochet border adds very little, but wide borders, fringe, and tassels can add 10% or more. If your pattern offers optional borders (like our lemon peel and bobble blankets do), the yardage for them is usually listed separately — check before you're one skein short on the last row.

The safe buying rule

Buy the top of the listed range, plus one skein, all from the same dye lot. Leftover yarn becomes amigurumi, bandanas, or stripes on the next project — running out three rows from the end becomes a story you tell for years.
