How to Choose Door Hinges

1. Identify the Door Type and Weight

The first step is understanding what kind of door you have and how heavy it is.

Interior lightweight doors (hollow-core): usually need 2 hinges.

Solid wood interior doors: typically need 3 hinges.

Exterior or heavy doors (solid wood, metal, fire-rated): require 3–4 heavy-duty hinges.

Fire doors: must use fire-rated hinges tested to relevant standards.

2. Choose the Right Hinge Type

Different applications call for different hinge designs:

Butt hinges: the most common type, mortised into the door and frame. Ideal for standard interior and exterior doors.

Ball-bearing hinges: contain bearings that reduce friction, making doors open more smoothly and quietly. Best for heavy or frequently used doors.

Concealed hinges: hidden from view, popular for clean, modern aesthetics.

Pivot hinges: rotate on a central pin, often used for glass or designer doors.

3. Check the Size and Screw Holes

Hinges come in standard sizes (e.g., 3", 4", 4.5", 5"). The hinge size should match the existing mortise if you are replacing hinges. Screw holes must align with the door and frame; otherwise, you may need to fill and re-drill, which weakens the wood.
