Not necessarily, you're mixing things up a bit.

A kingdom and an empire can have the same power and the same  size territory, the difference is that the empire grew absorbing other countries, taking them as vassal states through "deals" or war.

I don't know how to explain it..

A Kingdom is a country ruled by either a king or queen. It is usually ethnically homogenous with a common language, history, culture, and sense of identity. There should be consensus among the people that the monarchy has a de jure right to rule over them.

An Empire on the other hand, is a large multi-ethnic state ruled by a central authority, often through military force. It could consist of multiple kingdoms and other political entities, but they must all be subservient to the emperor. It is also usually defined by overseas/foreign territories. For example, the British empire was formed from the kingdoms of England, Scotland and Ireland, plus the numerous British colonies.
