How to Fit Internal Doors

If you haven’t fitted internal doors before, the first step is to measure the width of the opening. This is usually done by measuring the width between the inner sides of the door frame. You can also measure the height of the upper trim on the door and mark where the hinges should go.

Measure the width between the inner sides of the door frame

First, you need to measure the width of the oak interior doors frame. Measure from the left-hand corner, middle of the internal, and top-right corner. To make sure you get the correct measurements, make sure you lock the door before you begin. This prevents other people from opening it, which is essential if you replace the door on an exterior wall.

After determining the width, measure the depth of the door jamb. This is the width between the inner sides of the door frame and the wall stud. This measurement is usually twice the width of the door jamb.

Mark the hinge positions on the door

If you’re planning to make a set of internal doors, the first step is to mark the position of the hinges. You should mark them very lightly on the face edge of the frame. When you do this, the door will be supported on the inside edge with plenty of clearance on the top. This will prevent the door from jamming on the frame. You must also mark the hinge positions on the door in line with the recess in the frame.

Once you have marked the hinge positions on the internal doors, you can proceed to drill the holes. When installing a new hinge, you must ensure that the screws are positioned evenly on both sides. To ensure that you’ve marked the hinge positions correctly, you can use a particular drill bit available at most hardware stores and home centers.

Test-fit the hinges

Before installing hinges on your internal doors, ensure you have the correct measurement. If the doors are heavy, you should choose the correct hinges for them. The hinge fixing plate helps to ensure the proper alignment. The correct alignment of the hinge is essential to get the doors to hang correctly.

Before installing hinges, you must first test-fit them. This is usually done by making a small hole in the door’s surface, then setting the hinge in that hole. After ensuring the door is the right size, you can cut the mortise. Ensure the cut is even straight; otherwise, the hinge may come loose.

The width of the door and the number of openings are also factors that should be considered when buying hinges for internal doors. For example, a standard interior door will have two hinges, while a large entry of 90 inches or more needs three hinges.

Measure the height of the upper trim

You should take a few basic measurements before fitting an internal door. You can take the height of the frame of the door by measuring from the top left corner. You can use a stepping ladder or a chair to determine the exact height. Ask someone else to help you with the measuring if you have a limited reach.

When measuring the height of the door, you should not measure the existing entry. The correct measurement should be taken on the frame of the door itself. If the door is hinged on the left or right, you need to measure the width at the top, middle, and bottom.

Trim the door to suit the frame

To fit your door correctly, you must first measure the width and length of the opening. Generally, the door should fit between 1/8 and 3/8 inches from top to bottom. If the gap is more significant, use spacers such as folded matchbooks, cardboard, or shims. Once you have found the right size and width, you can mark where you need to cut the mortise locations.

To trim the door to fit the frame, you can use a circular or table saw. Set the blade to 90 degrees to minimize damage to the hinges and the frame. Also, use a straightedge clamped to the door to ensure a straight edge. Afterward, use tape to prevent the blade from tearing out.
