Terms of Service
Effective July 20, 2026. By using hookandgauge.com, you agree to the terms below.
Description of service
Hook and Gauge provides free, browser-based calculators for crochet gauge conversion, yarn and hook selection, yardage estimation, and project sizing. The tools are provided as-is, without any account, sign-up, or payment required.
Estimates, not guarantees
Every result these calculators produce is a proportional estimate based on standard industry gauge tables and the numbers you enter. Crochet tension varies by person, by yarn, and even by mood on a given day, and no calculator can account for that variation without an actual gauge swatch. We make no guarantee that a finished project will match a calculator's output, and recommend always crocheting and measuring a swatch before committing yarn and time to a full project. These tools are meant to save you arithmetic, not to replace your own measurements and judgment.
No professional advice
