| 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. | AAFA provides the list for information only and says it is voluntary, may contain omissions or inaccuracies, and is not legal advice. A global most-restrictive value is not a complete market or product determination. Verify the current controlling law, jurisdiction, product and component scope, exemptions, effective dates, test method, sampling plan, brand requirements, manufacturing-input controls, and other safety rules. | It is one curator's intentionally selective, off-Ravelry-oriented database, inventories change, and paid supporters can receive rotating priority placement; verify availability, fibre claims, shipping, and terms directly. | 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. | AAFA published RSL Version 26 on January 28, 2026 in searchable spreadsheet and PDF formats. The association describes it as a regularly updated reference to laws and regulations restricting chemicals in finished apparel, footwear, accessories, and home textiles. Its methodology records final-product or component limits, jurisdiction, test method, and comments, and excludes factory-process restrictions and non-chemical product-safety rules. | The individually researched database offers free listings and sortable yarn, fibre, designer, editor, accessory, and location views; the EU page spans multiple countries and direct seller profiles. | 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. |
