Time ProjectFrequently Asked Questions
How accurate are the calculations?
Our calculations are based on industry-standard formulas used by professional pattern designers. The yarn calculator includes efficiency factors to account for seaming, weaving in ends, and normal wastage. Results are typically accurate within 5-10% when you input accurate gauge measurements.
Can I use this for any knitting project?
Yes! Our calculators work for any type of knitting project - sweaters, scarves, blankets, hats, and more. The tools are designed to handle different yarn weights, stitch patterns, and project complexities. Just input your specific measurements and gauge.
What if I don't know my gauge?
The gauge calculator can help you determine your gauge from a swatch, or you can use our built-in heuristics based on yarn weight as a starting point. We always recommend knitting a gauge swatch for the most accurate results, especially for larger projects.
