Basket Size
The total number of distinct items or units purchased in a single retail transaction.
Full Definition
Basket size is a key retail KPI measuring how many items or units a customer purchases per shopping trip. It is used to evaluate the effectiveness of cross-selling initiatives, promotional events, and store layout changes. Depending on context, basket size may refer to unit count or to transaction value (basket value); editors must ensure the report consistently distinguishes between these two meanings. Basket size is two words when used as a noun phrase and hyphenated as a compound modifier.
Usage
Usage note: Two words as a noun; hyphenated ('basket-size metric') as a compound modifier. Distinguish clearly from 'basket value' (monetary amount) in every document.
