Parts of a Door Hinge
Before we can get into the types of door hinges, you have to know the different parts. We’re going to be using certain terminology throughout the article and if you don’t know what it means, it may confuse you. We’ll even go over a few parts we don’t mention, but are good to know.
- Leaf: also known as the wing, it’s the flat part of the hinge that’s screwed into the door and frame
- Knuckle: it’s the middle part, usually cylindrical, where the leaves meet. This is the part that allows the door to move
- Pin: a long piece that slides into the knuckle which keeps the two leaves together. When the pin is pulled out, you can remove the door slab from the frame
- Sleeves: the round pieces that make up the knuckle which hold the pin in place
Exterior Door Hinges
There are many exterior door hinge types. You want these hinges to be durable and strong so you won’t have to worry about them wearing down due to excessive use or from harsh weather conditions.
Plus, your exterior door’s hinges play a major role in keeping your home safe from intruders. Just like you’d want a strong entry door, you want the hinges to be strong as well. Weaker hinges will give out when facing extreme pressure.
Below are the different types of exterior door hinges that are available. We’ll help you determine which is best for your home.
One of the most common door hinges is the butt hinge. Butt hinges are composed of two identical leaves – one that’s attached to the moving component and the other on the fixed component. They’re attached by a curled barrel, also known as the knuckle, which allows the door to open.
One of the major reasons they’re common for entry doors is because they’re designed to support a lot of weight. Many steel, wood and fiberglass doors can be heavy which can damage weaker hinges. However, butt hinges won’t buckle under the weight.
There are several different types of butt hinges available, including:
- Lift-joint butt hinges: easy to separate the door slab from the frame – simply remove the center pin.
- Rising butt hinges: made for rooms with uneven floors
- Ball bearing butt hinge: made for heavier doors
Another common hinge style is the flush hinge. They’re designed to take up as little space as possible. They do this by having one leaf nestled into the other when your door is closed.
While they can’t hold as much weight as the butt hinge due to their design, they’re still durable.
Ball Bearing Hinge
While door hinges do wear down over time, some naturally last longer than others. One of the most durable door hinge styles is the ball bearing hinge. They’re built for heavier and wider doors.
The ball bearing is placed between two knuckles to reduce friction which wears down your hinges. Entry doors see the most traffic so it only makes sense that the hinges face the most friction.
Another benefit of ball bearing hinges is that they’re permanently lubricated. This allows the door to open and close easier and smoother – also helping reduce the amount of friction.
Case hinges are very similar to butt hinges which is why they’re perfect for a front door. The only real difference is that they have a more decorative design which will help improve your home’s curb appeal.
Another benefit of case hinges is that they come in many different shapes and sizes. Exterior doors aren’t the only place you’ll find these hinges – they can even be used for suitcases or briefcases.
If you’re looking for a shorter hinge, you should consider the hospital hinge. It’s much shorter than a butt hinge and has a rounded machined knuckle.
Otherwise, they’re designed very similar to a butt hinge. They have one leaf that’s installed the door frame and the other that’s attached to the door. They meet at the rounded knuckle which allows the door to operate.
Strap hinges, also known as gate hinges, are the most unique exterior door hinge style available. They’re the shortest by far but have the longest leaf. It gives your entry door a unique look that you won’t get with any of the other exterior hinges.
The strap hinge does more than just look pretty. The long leaf gives your door much more support. This will make the door much stronger which is exactly what you want from the entryway to your home.
Olive Knuckle Hinge
Have you ever seen a hinge that’s shaped like the letter H? That’s an olive knuckle hinge which is one of the more unique door hinge types. When the door is open, you see the H shape. However, when the door is closed, you only see the knuckle.
Some taller doors need the assistance of their hinges to keep them aligned. This is where the pivot hinge comes in handy. They’re made for taller doors because they pivot when they’re opened. They look very similar to an olive knuckle hinge.
Heavy Duty Hinge
Heavy duty hinges can come in any hinge style but are stronger than their normal counterpart. This is because they’re up to 1/4″ thicker than a regular hinge and built for heavier, more used doors.
Interior Door Hinges
Your home has more doors than the ones that grant you access to your home. Inside, there are doors separating each room that will need door hinges.
There are several interior door hinge types that you should be aware of that help determine how your door can be used. We’ll go over a couple of them below.
Double Action Spring

With two cylinders meeting a square leaf, they’re vastly different than all of the other exterior door hinges.
Butterfly hinges are made for interior doors because they can’t lift the weight of heavy exterior doors. Their decorative design (looking similar to a butterfly) will give your doors a touch of pizzazz and flair that you won’t get from a typical door hinge.
With many different shapes and patterns available, you can customize your butterfly door hinge to look exactly how you want.
