Choosing the correct size for your door lining can make all the difference in achieving both functionality and a professional finish. In this guide, we’ll walk you through standard internal door lining sizes, and key considerations to help you make the right choice. Whether you’re updating a single door or working on a more extensive renovation, this blog should give you all the information you need.
A door has several parts, with different names and functions, and this can sometimes be confusing if you are new to buying or measuring new doors! The door frame, the door lining, and the door itself are all slightly different but essential parts of the door opening needed for a functional door entryway.
What is a Door Lining?
A door lining is also often referred to as a door casing. The wooden framework fits around the edge of a door frame. This framework provides the base for attaching door architraves, which complete the decorative finish around the door. While "door lining" is often the more commonly used term, both refer to the same essential component that ensures a neat, functional, and aesthetically pleasing installation for your internal doors.
A door lining is the inside part of the door frame. It allows you to hang your door while providing a casing to remove the gap between the frame and the wall. The inner vertical sides or jambs are attached to the wall and create the sides of the door opening. The door lining is where you secure the door hinges and the door itself. It helps to ensure that the door is aligned correctly and operates smoothly wen fitted correctly.
Also sometimes referred to as a door jamb, the door lining prevents a door from sticking or jamming. It conceals brickwork or timber that surrounds the door itself. The lining is usually made of wood, and its job is not only to support the door but also to improve its overall appearance.
Door linings are typically about 1 13/16 inches thick. Allowing for 910mm for standard doors is recommended for door lining opening sizes.
What is the difference between a door Frame and a door lining?
The difference between a door frame and a door lining is that the door lining or casing hides the gap between the wall and the door, while the door frame is attached to the door and provides support.
A door frame holds your door securely in place. While it might not grab attention, the door frame is needed to ensure your door functions properly and fits into your space.
When choosing a door, selecting the right frame or lining to match its size and style is just as important. At Door Station, we offer various door frames in multiple sizes and designs to suit your needs.
The standard door frame size is around 6ft 8in, designed to accommodate standard interior doors. However, similar to doors, frames can vary in size, ranging from as small as 6ft 6in to as tall as 6ft 8.3in, allowing for flexibility in different spaces. Door frames are usually slightly wider than the door opening to ensure a snug and secure fit.
What Size is a Door Lining?
Internal door linings are available in many different materials and thicknesses, offering options to suit different design styles and functional needs. For a rustic, natural look, oak door linings are an excellent choice, combining elegance with durability. Additionally, fire-rated door linings are available, providing safety by helping to slow the spread of fire, making them a practical option for properties prioritising safety.
How Thick is an Internal Door Casing?
Door linings are typically around 1 13/16 inches thick, making them sturdy and reliable for most internal doors. MDF door linings can hold doors up to 2040mm tall and 976mm wide, offering flexibility for various door sizes.
Do I Need an Internal Door Frame, Door Lining, or Both?
When installing a new or replacement internal door, both the door frame and a door lining are essential for a neat finish and smooth operation.
The door frame is the supporting structure, securing the door and holding it upright. It provides the strength and stability needed for the door to function correctly.
On the other hand, the door lining is designed to cover the gap between the door and the wall, creating a clean, finished look. It also ensures the door opens and closes smoothly, preventing sticking or misalignment.
The frame and lining work together to provide functionality and a smart appearance for a professional and reliable internal door installation.
Plan Your Door Lining Opening for a Perfect Fit
When planning your door lining opening, leaving enough space for the door to fit correctly is essential—910mm is ideal for a standard door. This ensures that the door can be installed quickly and operates smoothly.
