# Dimensions Picker

Dimensions are the names, categories or characteristics of the digital marketing campaigns.

Each platform has its own dimensions, but some are common to many platforms, like **campaign names** , **ad names** , **campaign objectives** etc.

The dimensions Picker is the first of the **Reports** pickers.
