| 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. | This is a length-unit translation reference. It does not identify the measured feature; select, approve, or change a seam allowance; establish a universal fraction; interpret an unstated cutting or stitching line; or replace the exact pattern version, controlled specification, material and seam evidence, sample, production method, equipment, tolerance, or release authority. | A named organization on a dated partner list does not establish the exact legal entity or facility in scope, current status after the list date, product qualification, approved chemical article, process coverage, testing, delivery, performance, commercial fit, or permission for a particular claim or label. Use the separate current product, textile, chemical, criteria, and claim route that matches the decision. |

| 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. | NIST states that 10 millimetres equal 1 centimetre and that one inch is exactly 25.4 millimetres. The tool uses those relationships, displays rounded equivalents, exposes the size difference to the nearest 1/16 inch when converting to inches, and preserves valid value, source-unit, and target-unit state in the URL. | bluesign's current downloads page links general and brand-specific System Partner lists dated July 1, 2026. The general list separates brands and retailers, chemical suppliers, and manufacturers. The same official page routes product verification, the Textiles Guide, the Chemical Finder, criteria, and bluepass label and claim guidance as distinct checks. |
