King blanket yarn requirements
A king mattress is 76 × 80 inches; a king blanket with a drop is around 108 × 100 inches (274 × 254 cm). At 10,800 square inches it is more than three and a half throws.
Expect about 8,100 yards of worsted in stockinette, 10,250 yards in double crochet and around 12,900 yards in single crochet. Super bulky yarn needs roughly 4,000–5,100 yards — still 20 or more large blanket-yarn balls — and jumbo chenille for arm or hand knitting around 2,000 yards.
Because a king blanket is so heavy, many makers build it from squares, hexagons or panels and join them at the end. The calculator's estimate covers the fabric; add about 5% for joining with slip stitch or mattress stitch, and more if you crochet a join-as-you-go border on every motif.

- Add a safety margin. Keep 10% extra, or more for tight tension, borders and fringe.
- Check with a swatch. For the most accurate number, weigh a blocked swatch in the From a swatch tab and scale it to your project.
