There are many different types of doors, but they all have one thing in common—they all require a door jamb. While “door frame” and “door jamb” are often used interchangeably, they are two separate things.
A door jamb is an essential component of any door frame that serves as a support structure and facilitates the proper functioning of a door. As you're shopping for doors or looking to install one yourself, it's important to know the different terms and what they mean.
Door jamb versus door frame
A door jamb is an individual section of a door frame. Two side jambs make up the vertical components of the door frame and the head jamb is the top horizontal component. Together, the jambs (along with mullion) comprise the door frame.
A prehung door comes with the door and hinges already installed in a frame. The frame includes the door jambs, or legs (the vertical elements), as well as the header that forms the top of the frame and connects the jambs.
2. The jamb itself does not necessarily stop the swing of the door. On interior doors*, this is accomplished by another molding applied to the jamb called ``stop'' or ``doorstop'' (see diagram). Therefore, the word ``jamb'' does not necessarily denote a member that has the function of stopping the door swing.

The key difference between a door jamb and a door casing lies in their purposes. The jamb is structural, ensuring the door operates correctly, while the casing is decorative, enhancing the appearance of the door and the surrounding area. Together, they form a complete door frame, balancing function and style.
A pre-hung door is a door set consisting of everything that you need to install it into your opening. A slab door is simply just the door. A slab door is included in pre-hung doors. The difference being that the slab door in a pre-hung set will come with the frame and hinges already attached.
The standard size of a door jamb is 4 9/16 inches wide by 6 9/16 inches tall.
Cons: They may be more expensive than slab doors due to the additional materials and labour involved in manufacturing and shipping pre-assembled doors. It may not be suitable for all door openings, especially if the rough opening is not a standard size. It may require adjustments to fit properly.
If only one leg of the door jamb is damaged, usually the side where the lock and doorknob engage, known as the strike side, you can actually just replace the damaged side. This is a little trickier than it seems at first, but it's certainly not an impossible task.
A jamb (from French jambe 'leg'), in architecture, is the side-post or lining of a doorway or other aperture.
The Same Color
If you want to play it safe and rest easy knowing that everything will look fantastic, then matching your door and trim colors is the way to go. Trim is traditionally white or off-white, so matching your doors to the same shade will always be on-trend. You don't have to paint your trim white.
Yes, it is possible to install a door without a door frame, and this is commonly done using a slab door. Unlike pre-hung doors that come with a pre-attached frame and hinges, a slab door is a standalone unit without these components.
In simple terms, a door jamb is a frame that surrounds a door opening in a wall. It's typically made up of three pieces: two vertical pieces called the "legs" or "side jambs," and a horizontal piece called the "head jamb." Together, these pieces form a rectangular frame around a door.
Simply put, the door jamb is a specific part of the frame. It's there to take the weight of the door, as well as help keep the rest of the frame square and stable. Your hinges are affixed to the jamb on one side of the door, while the bolt passes through the jamb on the other side.
The door jamb is vital to the running of the door. This is where the hinges are placed to hang the door, as well as the striker plate on the opposite door jamb which helps you to open, close and lock your door. The door frame is all the elements combined.
Sill / Threshold
· The bottom or piece of a door. Usually made from aluminum or wood.
A slab door is a door without the frame or hinges. Door slabs can be purchased with a pre-cut hole for the doorknob, but the hardware—including doorknob, hinges, and strike plate—need to be purchased separately.
While it may seem daunting, hanging a new door in an existing frame is a project many homeowners can tackle with the right tools and guidance.
There are two types of interior doors, a prehung door and a slab door. Slab doors, also known as blank doors, include just the door and not any part of the frame. You'll have to attach the hinges to the door and that requires very precise work.
a peephole or a very small window in a door. Also called: judas window, judas hole.
A door trim that is flush to jamb can lead to unintentional gaps forming over time as the wood dries or the house settles. Installing the door trim slightly away from the jamb edges will help hide the discrepancies.
Margins (sometimes also called “rebates”) are the spaces between the door and the door frame. These are often important if you're looking at issues with your hinge jamb. Again, these spaces can be broken down into specific types: the hinge margin, strike margin, top (header) margin, and bottom (sweep) margin.
