| Know before using | 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 request does not set product-specific pass values, prove fitness or safety, validate claims, replace laboratory testing, or determine legal compliance. | PatternReview combines community reports, membership, education, advertising, and retail, so it is not a neutral or complete pattern index. Reviews are individual experiences rather than standardized fit tests. Confirm the exact pattern version, size range, measurements, fabric, format, errata, licence, seller terms, and current availability with the designer or publisher. Paid catalogue and search features do not establish an export route or continued access after membership ends. | The result is a numerical unit conversion, not a new measurement or conformance decision; it does not establish sample or lot representativeness, significant digits, drape, warmth, opacity, thickness, stretch, strength, shrinkage, durability, sewability, end use, target, or tolerance. |

| What the source establishes | 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 request uses official textile test-method scopes, labeling guidance, and trade capability questions to keep specifications, methods, samples, substitutions, and supplier evidence comparable. | PatternReview's current site exposes recent pattern, sewing-machine, and store reviews, forums, contests, classes, classifieds, a pattern shop, and a searchable review gallery. Its account FAQ says most participation requires a free activated account. Friends of PR adds advanced search, a personal pattern catalogue and wishlist, bookmarks, classifieds, a photo album, discounts, and other features through a recurring paid membership with a published email cancellation route. | The calculator uses the NIST SP 811 Appendix B.8 conversion from avoirdupois ounces per square yard to kilograms per square metre and links to a source-reviewed fabric mass record for method, sampling, conditioning, and product controls. |
