Know before usingA generated pattern is not independent fit evidence or a production-ready graded block. The result still depends on accurate measurements, the selected design and options, ease assumptions, fabric behavior, construction, and representative test garments. An account stores saved patterns and measurement sets, so review the platform's privacy terms before retaining personal measurements.It is a translation and orientation layer, not legal advice, certification approval, a purchased standard, or proof that a supplier, sample, or lot conforms.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.A unit reference; the correct allowance depends on material, seam type, and production method.

Source and review
What the source establishesFreeSewing's official documentation says the browser editor drafts a selected design in real time from a measurement set rather than scaling or grading a standard-size pattern. Users can adjust design options and export the generated result, including as PDF; saving the pattern to an account is optional and is used to revisit it later.Each entry includes plain-language aliases, a working definition, a decision boundary, a checked source, and an internal next step; a repository audit enforces completeness and review dates.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 linked tool or guide is maintained inside Stitch Authority and was checked against its current public interface.
