GLOSSARY OF TERMS Grade (noun)

The total increase or decrease in circumference between each size, e.g., 2" between size 12 and 14; or the incremental growth/decrease at each cardinal point on a pattern piece.

Grade (verb)

To proportionally increase or decrease the size of a pattern.

Total or overall grade

The total increase or decrease in circumference between each size. For example, 2" between size 12 and 14.

Allocated grade

The portion of the total grade to be applied to one pattern piece.

Incremental grade

The growth/decrease at each cardinal point on a pattern piece.

Nest or graded nest

A set of graded pattern pieces stacked, illustrating the difference in each size. You will also see graded nests in multi-size patterns.

Cardinal points

The places on a pattern piece where we will insert or take away room to increase/decrease its size.

Grade rule library

Also called Grade Rule Table or Chart; a list of cardinal points along with their grade increments for each pattern piece.

Base size

Also called the master pattern; the original (usually middle) pattern size that is graded up and down to create the full size range

Production pattern

A master pattern which has been graded for all of its sizes.

True up or truing

Checking the graded pattern pieces to ensure they fit accurately together at their connecting seams.

Size run

The sizes in a specific style, such as 4, 6, 8, 10, 12

Machine grading

Mechanically moving a pattern to grade. When this method is used, the pattern is clamped into the grading machine and a knob is turned to set the grading increment.

Computer grading

The base pattern is first digitized, then grade rules are applied using software to create the new sizes.

Manual/hand grading

Grading on paper using ruler and pencil.

Cut and spread grading

Manually grading by cutting the pattern apart along cardinal points, then either spreading to grade up or overlapping to grade down.

Pattern shifting

Grading the pattern by shifting it back and forth, up and down along an X and Y axis.
