When you need to know for sure, this is the tool to grab!
This classic black plastic gauge measures all your knitting needles, from the tiniest US 000 (1.5 mm) up to US 15 (10 mm). It also has a handy 2″ measuring guide to help you figure out your stitch and row gauge.
Heads up: This gauge doesn’t include a slide-out blade—the slot on the back is just part of the design.
