Yarn Weight Measuring Tool

When yarn labels are missing—or when you’re working with handspun, hand-dyed, or leftover yarn—a wraps per inch gauge helps you identify the yarn’s weight and thickness with confidence.

This compact tool lets you identify yarn weight in two simple ways. Wrap your yarn neatly around the inch-wide notch end to end and count the wraps to determine wraps per inch (WPI). Or, lay the yarn into the etched grooves to see which standard yarn weight it corresponds to—from lace through fingering, sport, DK, worsted, aran, bulky, and super bulky.

Finished with a small, unclaspable ball chain, it’s easy to clip onto a project bag for quick access—perfect for yarn shopping, stash sorting, and planning on the go.

Whether you’re sorting your stash or matching yarn to a pattern, this tool helps you identify yarn weight and choose a needle size that will give you the correct gauge—even when the label is gone.

Lightweight and easy to tuck into a project bag, it’s a practical addition to any knitter’s, crocheter’s, weaver’s, or spinner’s toolkit.
