Yarn Amount Estimator

This tool gives you a general estimate of how much yarn you may need for your knitting project. Yarn density can vary between yarns (handspun especially), so treat this as a helpful starting point. Enter your project type, yarn thickness, and measurements to get an approximate amount of yarn you may need in grams. Keep in mind that stitch patterns also affect yarn usage: light, open lace uses much less yarn than dense textures like cables or brioche. Longer cuffs or folded brims can also increase yarn usage.

The estimated yarn amount will appear here once you choose your project and yarn weight, enter your measurement(s) and click “Calculate.”
