A size curve is a target size mix — for example XS 10%, S 20%, M 35%, L 25%, XL 10% — that a plan should respect. Rules can flag plans that deviate too far from the curve.

​
Scope

A size curve is typically scoped per brand. (Category and season scopes exist in the model and are reserved for future use.)

​
Rules

A curve is enforced by a size-curve rule from the catalog — for example a deviation-percentage threshold. The rule uses the projected deviation between the plan’s size mix and the target curve, and warns (or blocks) when it exceeds the threshold.

​
Working with size curves

1

Open size curves

Go to Intelligence layer → Size curves.
2

Define the curve

Add one row per size with a target percentage. The percentages must sum to 100%.
3

Attach a rule

Add a size-curve deviation rule to the relevant ruleset and set its threshold.
You can also import a curve rather than entering each size by hand.
