| Know before using | 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. | The record does not reproduce licensed code diagrams, verify a user's proposed code, authorize an ISO and ASTM crosswalk, select a construction, set stitch density or machine settings, prove supplier repeatability or performance, or replace the licensed standards and qualified construction, sewing, production, testing, safety, and quality review. | Free access does not grant commercial reproduction or sale rights; uses beyond one personal copy must be resolved with the designer or author. Knitty says it tries to avoid errors but disclaims responsibility for pattern and technique inaccuracies. Check the live page for corrections, verify gauge and measurements, and confirm permission before any commercial use. |

| What the source establishes | 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. | The guide cites the official DLA cancellation record for FED-STD-751A and the current public scopes and statuses of ISO 4915:1991, ISO 4916:1991, and ASTM D6193-16(2025). It records ISO 4915's July 2026 systematic review and keeps classification, ambiguous-code recovery, translation, complete process definition, physical verification, and performance evidence separate. | Knitty currently publishes web-only editorial issues containing original knitting and crochet patterns and articles. Its legal page states that patterns are free for one person's personal use, identifies each designer or author as the copyright holder, and explains that verified pattern corrections are posted in bright pink on the pattern page. |
