If you mean: “I need the amount each pattern point moves from one size to the next”
Grade rule
Also heard as grading increment · size increment · pattern grade
A coordinated set of horizontal and vertical increments used to create other sizes from a base-size pattern while preserving intended proportions.
- Why it matters
- One uniform percentage rarely preserves fit. Different body areas and pattern points need different movements across a size range.
- Say or ask
- “Which base size, size chart, POM increments, and grade rule control this nested pattern?”
- Boundary
- Grading extends an approved base pattern; it does not repair an incorrect base fit or prove every size works on bodies.
