| Best for | Finding the current CYC hook and needle aliases that share one known nominal metric diameter before confirming project gauge | Coordinating an independent sewing-pattern test | Documenting a bounded sample-to-area yarn calculation when the equivalent area is already known and genuinely comparable with the sample | Auditing inherited grade rules or controlling a new multi-size pattern release from approved targets through sample evidence |
| Know before using | A shared nominal diameter does not make a knitting needle and crochet hook interchangeable or predict equal gauge or fabric. The reference is not a physical measurement, manufacturer inspection, UK or Canadian conversion, steel-hook chart, tool recommendation, yarn assignment, or project approval. | The interface and plan description do not prove tester reach, completion, feedback quality, fit validity, export quality, uptime, support, or suitability for an established release process. Measurements and photos can be sensitive personal data. Run a non-critical pilot, review the current privacy and service terms, define consent and photo rights, test exports and deletion, and keep pattern approval and release responsibility with the designer. | The worksheet does not establish that a sample represents a project, derive the area of shaped pieces, account for construction or openings, prescribe reserve, supply typical project quantities, round to packages, verify label values, guarantee required quantity, check dye-lot supply, or replace a tested pattern amount. Yarn, tool, maker, strand count, stitch or texture, density, treatment, finishing, planned area, and supply decisions remain project-specific. | The record does not create a production grade, supply universal increments or breakpoints, validate a CAD file or fit population, reproduce licensed standards, or replace qualified anthropometric, pattern, technical-design, fit, quality, accessibility, safety, statistical, and user-research review. |

| What the source establishes | Rechecked July 28, 2026. The lookup reproduces the current public Craft Yarn Council metric and U.S. alias rows, aligns hooks and needles only when their nominal millimetre value matches, and leaves missing rows or aliases unfilled. | Pattern Testers currently offers application intake, tester selection, feedback, photos, approvals, issue tracking, revisions, a reusable tester directory, and release deadlines. The public pricing page shows a limited free plan and paid Pro and Business tiers. Its June 2026 privacy policy lists names, email addresses, measurements, photos, feedback, application history, and assignments among the data processed. | The worksheet performs visible proportional arithmetic on user-entered sample dimensions, sample yarn length or weight-derived length, equivalent area, and optional reserve. Craft Yarn Council pattern-writing guidance says yarn amounts and package counts should be recorded in instructions, and its consumer guidance ties project instructions to a stated yarn amount and representative gauge; those sources do not establish a universal sample-to-area method, project range, or reserve. NIST defines 1 yard as exactly 0.9144 metre for the secondary unit display. | The guide cites current ISO body-table, size-designation, and garment-measurement boundaries plus two peer-reviewed studies that tested the relationship between conventional grade rules, anthropometric evidence, and garment fit; it requires product-specific target deltas and validation instead of publishing universal increments. |
