How We Calculate This
This calculator estimates yarn for socks based on foot circumference, foot length, and cuff length. Sock yarn consumption is well-documented and varies predictably with size.
The formula
Sock area = Foot circumference x (Foot length + Cuff length) x 2 (for a pair)
Yarn = Area x Grams per cm² x Metres per gram
