Knitting & crochet calculator

Stash-Buster Project Matcher

Enter your yarn weight and available yardage, meters, or grams to instantly see every viable knitting and crochet project that fits comfortably within your stash budget with built-in safety margins.

Every crafter has odd orphan skeins, single skein impulse purchases, and leftover partial balls languishing in their yarn bins. Starting a project without verifying yardage leads to losing 'yarn chicken' right at the bind-off edge or collar.

This calculator matches your exact available yardage against a comprehensive library of real-world project archetypes—from quick weekend dishcloths, mittens, and beanies up to shawlettes, baby blankets, and garments. It automatically calculates your yardage safety buffer (aiming for at least 10% to 15% surplus) and shows which larger projects are within reach if you add just one complementary skein.

Frequently Asked Questions

How much safety buffer yardage should I always have?

We recommend keeping a 10% to 15% yardage buffer above pattern requirements. Minor variations in tension, looser cast-ons, and generous swatching will consume extra yardage that pattern ball bands do not account for.

Why does crochet need more yardage than knitting?

Crochet fabric is constructed of wrapped posts and interlocking loops rather than single interlocking open loops, consuming approximately 20% to 25% more yarn for the identical finished surface area and weight category.

How do I calculate yardage if I only have a kitchen scale and grams?

Switch the unit selector to Grams (g). The tool applies industry standard yarn density factors (e.g. ~440 yds per 100g of fingering, ~200 yds per 100g of worsted) to accurately convert your physical ball weight into usable yards.

What can I make with a single 100g skein of worsted yarn?

A standard 100g skein of worsted (~200–220 yards) comfortably makes a classic adult beanie, a pair of fingerless handwarmers, a cozy textured neck cowl, a twisted ear-warmer headband, or a baby bonnet and bootie set.
