The Pattern Grading Calculator automates the mathematical process of enlarging or reducing garment patterns. By applying industry-standard ASTM rules (D5585 for Women, D6458 for Men, and D6192 for Children), it calculates precise grade rules for various anatomical landmarks. Use calculate_standard_increment to find total circumference changes, distribute_size_increments to split growth between bust, waist, and hip, or compute_pattern_grading_table to generate a complete measurement difference table for any target size.

3 tools expose this connector's capabilities to your AI agent.

distribute_size_increments

Splits a total circumference change into specific, usable increments for key body landmarks

calculate_standard_increment

Determines the total amount of circumference change required for a single size jump within a chosen standard

compute_pattern_grading_table

Generates a complete table showing how much every individual pattern point should move for a specific target size

How much total circumference change should I expect for 2 size jumps in the Women's standard?

For a 2-size jump using the Women's ASTM standard, the total cumulative change in circumference is 5.0 units.

If I have a total change of 6cm to distribute, how much goes to the waist?

Using standard distribution, the 6cm change is split into 2cm for the bust, 2cm for the waist, and 2cm for the hip.

Generate a grading table for a target size of 1 jump up from base measurements: {'bust': 90, 'waist': 70, 'hip': 95} using Men's standard.

The generated grade table shows an increase of 2.5cm for the bust, waist, and hip landmarks, with corresponding shifts for neck and armscye points.

The tool follows ASTM D5585 for Women, D6458 for Men, and D6192 for Children to ensure consistent fit across sizes.
