Needle Size Calculator

How It Works

Needle size is shown as European/American (e.g., 80/12). Lower numbers are finer needles for lighter fabrics. The needle type matters as much as size: universal needles work for most wovens, ballpoint needles push between knit fibers instead of piercing them, and sharp/microtex needles give clean stitches on tightly woven fabrics. A dull or wrong needle causes skipped stitches, fabric damage, and thread breakage.
