What is the outside door called?

The outside door is generally called the exterior door, and when it serves as the main entry facing the street, it is commonly known as the front door. Names can vary by region and context.

Terminology and common usage

Understanding the terms people use helps distinguish between the door itself and its position relative to the home.

Common terms used to describe doors that lead from outside into a building:

• Exterior door — the door fitted to the outside boundary of a building, designed to resist weather and provide security.


• Front door — the exterior door at the building's main entrance, typically facing the street and used by visitors.


• Back door — the exterior door at the rear, often used as a secondary entry or for service access.


• Primary entrance — a broader term for the building's main entry point, which may be a single door or a set of doors.


• Entry door — a common catalog term for the door that serves as the entry into a building.


• External door — term used in UK and some Commonwealth countries, equivalent to exterior door.

In everyday conversation, people usually say "front door" for the main entrance and "back door" for secondary entrances, while "exterior" or "external" door is the more technical term.

Types and features of exterior doors

Exterior doors come in several materials and designs to balance security, energy efficiency, and aesthetics. Here are the main categories:

• Solid wood doors — classic appearance with natural insulation; typically heavier and may require maintenance.


• Wood-composite doors — engineered to resist warping and weather while mimicking wood.


• Fiberglass doors — durable, energy-efficient, and low maintenance, available in various finishes.


• Steel doors — strong security with good insulation; often used for high-security entryways.


• Aluminum doors — lightweight and modern in look; common for contemporary designs or patio entries.


• Glass-inset doors — provide natural light; usually reinforced for security and paired with sidelights or transoms.

Choosing the right exterior door depends on climate, security needs, energy efficiency, and architectural style. Contractors and homeowners weigh durability, maintenance, and hardware quality when selecting a door.
