Assortment planning determines which products a retailer will carry and how deeply to buy them, while a size curve allocates that depth across sizes for a store or cluster.

The range must satisfy brand and category intent while respecting demand, space, budget, minimum order quantities and option count. Localisation then adjusts the choice for different store or channel profiles.
A style-level buy can still fail if its units are in the wrong sizes. Connecting the curve to forecast demand and later sales makes broken-size risk visible before allocation.
A size curve is the proportion of an option’s units assigned to each size for a defined store, cluster, channel or demand profile.
A starting curve can be inferred from comparable products and the target store profile, then updated when real sales arrive.
