Compact MPV is a vehicle size class for the middle size of MPVs. The Compact MPV size class sits between the mini MPV and large MPV (minivan) size classes.

Mini MPV—an abbreviation for mini multi-purpose vehicle—is a vehicle size class for the smallest size of minivans/MPVs. The mini MPV size class sits below the compact MPV size class and the vehicles are often built on the platforms of B-segment hatchback models. By the European definition, the mini MPV commonly consists of cars with two rows of seats, while in Asia mini MPVs with three rows are common. Sliding doors are sometimes also fitted to mini MPVs. Mini MPVs are also called tall-hatchbacks or small MPVs.
