Guide to 13 Types of Hinges
Understanding the various types of hinges can be helpful when choosing the right hinge for your interior and exterior doors, cabinets, or drawers.
What Is a Hinge?
A hinge is a movable joint that connects two objects, allowing one to swing while the other remains fixed. This mechanism enables the swinging motion of doors, cabinets, and even some windows in your home. Interior and exterior doors, as well as kitchen cabinets, rely on different types of hinges to function smoothly.
Each type of door or opening has a specific hinge suited to its purpose. Cabinet doors use cabinet hinges, while standard doors require door hinges. Within these categories, there are further variations based on style, functionality, and budget. Even briefcases use a specialized hinge to open and close.
When the hinge leaves are attached to both the door frame and the door, and a pin is inserted through the barrel, the door should open and close with ease. Typically, multiple hinges are needed for both interior and exterior doors, though you generally won’t need them along the entire length of the door unless dealing with very heavy or specialized doors.
Occasionally, the moving parts of the hinge, known as knuckles, may become tight or squeaky and require lubrication to maintain smooth operation.
4 Parts of a Hinge
To understand how a hinge functions, it's essential to know its key components. Here are the parts of the most common types of hinges:
Hinge Leaf: These are the flat plates attached to the door frame and the edge of the door, with one hinge leaf secured to each surface.
Knuckle: The knuckle is the cylindrical section of the hinge where the pin passes through.
Barrel: A series of connected knuckles forms the barrel of the hinge.
Pin: The pin is the long piece that slides through the barrel, holding the hinge leaves together.
13 Types of Hinges
There are many different types of hinges, each designed for specific purposes. Here are some common types of hinges and their typical uses:
Barrel Hinge: Not to be confused with the barrel component of a hinge, barrel hinges are compact and resemble butt hinges. They are ideal for small cabinets or storage chests.
Butt Hinge: One of the most common and heavy-duty hinge types, consisting of two leaves joined by knuckles. One leaf is attached to the door, the other to the frame. Subtypes include lift-joint hinges, rising butt hinges, and ball bearing hinges, often made of stainless steel.
Butterfly Hinge: A decorative hinge available in light- and heavy-duty versions, used where hinges are visible, such as on furniture or cabinets.
