How Do Factories Grade Leggings Inseam Length Across Sizes?

Leggings inseam grading follows the brand's body-length strategy rather than a universal increment.

Grading and approval require controlled records, not just a larger or smaller copy of one sample. Keep size-specific measurements, fit comments, and revision history together so the factory can reproduce the approved proportions across the full intended range. Check proportions across standard, petite, and tall ranges.
