hobby.knitting-yarn-calculator Calculator
Calculates total yarn needed in metres and number of skeins for a knitting or crochet project from pattern gauge, finished dimensions, and skein length. Buying all yarn from the same dye lot is critical — this tells you exactly how many skeins to buy before they sell out.
Inputs
Pattern Yards
Reference formula or conversion factor shown for context.
Skein Yards
Linear measurement. Ensure consistent units: 1 m = 1,000 mm = 3.281 ft.
Gauge Spi
Reference formula or conversion factor shown for context.
Tension Factor
A multiplier applied in the calculation.
Results
skeins needed
Sample size or count used in the calculation.
total yards required
The combined total across all inputs and components.
yards per skein
Sample size or count used in the calculation.
tension adjustment
The tensile force or stress — the pulling force that stretches the material. Must stay below the material's tensile strength.
always buy extra
