Concealed / European Hinges
European hinges, sometimes called concealed hinges or flush hinges, are mounted on the inside of the door, which means you don’t actually see them from the outside of the door. Primarily used for cabinet doors, this type of hinge provides a clean and modern look.

Continuous / Piano Hinges
Piano hinges, sometimes called continuous hinges, run the full length of the door, distributing the full weight of the door along the whole hinge. This is the type of hinge used for piano lids, hence the name. However, it’s also not uncommon to find these used on smaller household items, such as a jewelry box or storage chest.

For doors, specifically, continuous piano hinges are the top choice for blast doors, commonly used on home safes, bank vaults and bomb shelters. In recent years, this type of hinge has become a popular choice for barn doors and other rustic decor.

Flush Hinges
Flush hinges are another common choice for cabinets or other lightweight interior doors. They’re partially hidden on the outside, but not entirely concealed like European hinges. They don’t require a cutout to be installed like mortise hinges; they can be attached to the surface of the door with screws.
