Yarn yardage calculator
How much yarn a blanket needs is one of those questions with a famously long answer — gauge, stitch density, and yarn weight all move the number. This blanket yarn calculator gives you a grounded starting point: enter the finished length and width, pick your yarn weight from the standard 0-to-7 categories, and set your yards per skein and waste allowance. The math is calibrated so a 50×60 throw in worsted weight lands near the 1,800 yards most yarn guides cite, then scales across the other weights. The skein count rounds up so one dye lot covers the whole project. Treat the result as a planning estimate and let a swatch refine it.

How it works
- 01
The estimate starts from your project's area in square inches.
- 02
Each yarn weight carries a yards-per-square-inch factor, calibrated so a 50×60 throw in worsted weight lands near the 1,800 yards most guides cite.
- 03
Your waste allowance is added for swatching, fringe, and weaving in ends, then divided by yards per skein and rounded up to whole skeins.
