How it works
Scarves use the rectangle yarn model with an 8% waste factor. Open lace uses less yarn than the average; dense rib uses more.
Worked example
8×60" worsted knit scarf at 200 yd/skein: expect about 2–3 skeins. A 20×70" DK wrap can need 600–900 yards.
Tips
For cowls, use circumference × height as width × length. Fringe adds 10–20 yards typically.
Common mistakes
Planning only one skein of gradient yarn for a long scarf.
Dimensions people actually make
Narrow scarves of 6–7" wear neatly under coats; 8–10" is a common handmade default; shawls and wraps 18–30" wide need substantially more yarn. Infinity scarves: treat the loop circumference as length. Blocking lace open increases area without using more yarn—estimate from pre-block dimensions for yardage, then block to shape.
Limits and how to use the results
Estimates run only in your browser. Prefer a published pattern’s tested yardage when it conflicts with this planner. Density factors and assumptions are documented on the methodology page; legal terms cover planning-use limits.
