Make the pattern your own! Swap yarns, use what you have, or see if a cheaper option works. Yarn Math compares yarn thickness and estimates how much you’ll need.
Want to use a different yarn for your pattern? Make the project your own, use yarn from your stash, or compare a cheaper alternative. Yarn Math helps you check the thickness match and estimate how much you’ll need.
• Compare length and weight per skein.
• Find which number of strands gives the closest thickness match.
• Estimate how much yarn your project needs and how many skeins to buy.
• Account for yarn you already have.
• Compare two yarns held together with one yarn, in either direction.
• Convert to meters per 50 g or yards per 1.8 oz.
• Save calculations on your device. Add yarn names and prices to track costs and potential savings.
• Choose your language and measurement units in Settings.
Results are estimates based on the information you enter. Knit a gauge swatch before starting your project. A subscription is required to use the calculators.
