They’re very similar, but not exactly the same. Here’s the distinction:

Sideboard

  • Traditionally used in dining rooms for serving food and storing tableware.
  • Often has short legs or sits closer to the floor.
  • It can include cabinets, drawers, and sometimes a hutch on top.

Credenza

  • Originated as a dining room piece too, but over time became more common in offices or living rooms.
  • Tends to have a sleeker, low-profile design with little or no legs (often sits directly on a plinth/base).
  • Known for a modern, streamlined look compared to the sometimes ornate sideboard.

In everyday use, many people use sideboard and credenza interchangeably, but design-wise, a sideboard is more traditional and dining-focused, while a credenza leans more modern and multipurpose.
