How Much Yarn Do You Need? A Project-by-Project Estimator

Why Yarn Estimation Matters

Running out of yarn halfway through a blanket, especially from a dye lot you can't rematch, is one of the most frustrating crochet experiences. Estimating ahead saves money, trips to the store, and mismatched dye lots.

Quick Reference by Project

• Dishcloth/coaster: 20-50 g
• Baby hat or mittens: 50-100 g
• Adult scarf: 150-300 g
• Amigurumi (small): 50-150 g
• Adult sweater: 600-1200 g depending on size and yarn weight
• Throw blanket: 1000-2000 g
• Full-size afghan: 1800-3000 g

Factors That Change the Math

• Stitch pattern: Dense stitches like single crochet use more yarn than open lace or filet work.
• Yarn weight: Bulky yarn covers area faster but needs more grams per meter.
• Gauge: Tighter tension means more yarn per row.
• Pattern instructions: Always check the suggested yardage in the pattern first; our estimates are for when no pattern exists.

Buy a Little Extra

Even with careful math, buy 10-15% more yarn than you think you need, especially for garments. Leftover yarn is far less annoying than a mismatched dye lot bought weeks later.
