Calculate yarn requirements, gauge, and project measurements for your crochet projects
Accurate gauge measurement is the foundation of successful crochet projects. This calculator helps you determine exactly how many stitches and rows you'll need based on your gauge swatch, ensuring your finished project matches your desired dimensions.
Whether you're making a cozy blanket, a delicate shawl, or a cute amigurumi, knowing your yarn requirements upfront prevents mid-project trips to the store and helps you budget accurately for your crafting supplies.
| Yarn Weight | Typical Gauge | Hook Size | Best For |
|---|---|---|---|
| Lace (0) | 32-42 sts / 4" | Steel 6-8 | Doilies, thread work |
| Fingering (1) | 21-32 sts / 4" | B-E (2.25-3.5mm) | Socks, shawls |
| Sport (2) | 16-20 sts / 4" | E-G (3.5-4.5mm) | Baby items, light garments |
| DK (3) | 12-17 sts / 4" | G-I (4.5-5.5mm) | Sweaters, accessories |
| Worsted (4) | 11-14 sts / 4" | I-K (5.5-6.5mm) | Blankets, afghans |
| Bulky (5) | 8-11 sts / 4" | K-M (6.5-9mm) | Quick projects, rugs |
| Super Bulky (6) | 5-9 sts / 4" | M-P (9-15mm) | Chunky blankets, scarves |
Always crochet a 6×6 inch swatch using your project yarn and hook. Measure the center 4 inches to count stitches and rows. Wash and block your swatch the same way you'll care for the finished project, as some yarns change gauge after washing.
Purchase 10-15% more yarn than calculated to account for gauge variations, mistakes, and dye lot differences. It's better to have extra yarn than to run short and be unable to match the dye lot later.
Crochet speed varies by skill level and stitch complexity. Beginners typically work at 800-1000 stitches per hour, while experienced crocheters can achieve 1500-2000 stitches per hour. Complex patterns with frequent color changes or texture stitches take longer.
Different stitches use different amounts of yarn. Single crochet uses the least, while double and treble crochet use progressively more. Textured stitches like bobbles or popcorns can use 20-30% more yarn than basic stitches.
