What interior doors can be trimmed in height. How to cut the leaf of the interior door correctly
If you had to trim the door after installing the hinges, it means that you misdimensioned the box relative to the leaf, or made a mistake with the hinges. In the latter case, it will be more correct to correct the error. Before fixing the doors on the hinges make sure that the dimensions of the leaf are shorter than the width of the frame by about 10 mm and narrower by 4-5 mm, and the lines of the leaf and thumbtacks are parallel. At the same time you can make sure that the vertical frame pillar from the side of the hinges is perfectly flat, it is very important.
Sometimes the question arises. how to shorten the door after an unintended installation of laminate or parquet. The network is full of descriptions of how dashing installers handle this operation with a trimmer circular saw. We recommend that you do not follow this advice under any circumstances. If you can allow such an operation on a door made of fiberboard, the veneer of precious wood will most likely be spoiled. The difficulty is that even the smallest teeth of the saw will tear particles of veneer, forming chips and crevices, it is impossible to fix such a defect.
Nevertheless, it is possible to accurately trim the height of doors. In Runet it is advised to do with a powerful hand electric milling machine and a guide ruler. The method is real, but you will swallow a lot of dust, and the figured overlay decor does not always allow you to securely fasten the ruler. It is easier to do this operation with an electric planer, professional door assembly can’t do without this tool. In particular, a competent carpenter, using an electric planer, forms on the vertical part of the leaf, facing the hinges, an angle slightly different from 90° and open towards the doorstop. As a result, the hinges are also slightly ajar when closed, which removes all tension between the box and the leaf.
Before trimming, you should remove the leaf from the hinges and tape both sides of the bottom of the door with painter’s tape. This is also done in the case of the operation with a router. the tape will prevent chipping and protect the lacquer from scratches that may occur when in contact with the platform of the tool.
Before you trim the doors with the electric planer, use a pencil to draw a trimmer line on your masking tape to help you find your bearings. Do not bring the planer to the opposite end, so as not to chip it, remove layer after layer from both sides of the blade. Try to install the doors on the hinges, not yet reaching the pencil mark. by cutting off too much, you will have to put up with too much of the lower gap.
The best solution is to entrust the work to a craftsman representing a well-established company. Attention to your problem combined with professional skills will guarantee successful results.

Tips from the pros
Solid or fiberboard panels can be trimmed from below, as long as they do not have mouldings or imitations. If the decor is symmetrical, it is better to cut from both sides, dividing the size of the cut part by 2. These measurements are to be taken from each edge without disturbing the symmetry of the upper and lower panels. This is also the case if the standard width of the door leaf needs to be reduced.
Do not shorten hollow-core frames by too much. The product consists of wooden blocks of limited thickness. When carrying out the work, at least 1-1.5 cm of the frame timber must be left inside the leaf.

If during the opening scratches the floor, the problem is solved by hard sanding, attached to a thin wooden plank. It is placed under the leaf, open and close several times. The problem is eliminated by friction, and the door begins to walk freely when using.
With a small sag, you should not immediately start trimming, it is better to use a grinder, planer or hard sandpaper first.
The situation is more complicated if the height of the floor surface has changed, or simply the door leaf is larger than necessary. The problem is solvable, and it can be done quickly if you use a few tips.
Preparation of tools
- Clamps, which will ensure a quality fixation of the guide bars and the surface;
- for precise trimming you need a ruler, angle, centimeter;
- planer can be manual or electric;
- A sharp knife will come in handy when processing veneer material;
- wood chisel;
- Edgebanding for fiberboard products;
The list of tools depends on the material. When making a cut can crack the edge of the surface, then the help comes with masking tape.

Preparing the door leaf for work

Before you yourself begin to trim the door from below or above, you need to carefully measure the leaf, the doorway, take into account the location of the hinges. If the problem is caused by changing the height of the floor, changes are best made from below.
From the bottom
- Measures should be taken from the opening and from the side of the hinges and where the door pretends to be. Transfer the measurements to the working canvas, starting from the top, moving downwards. The received points should be connected by a straight line with a long ruler, the angle piece in this case will help to control corners.
- Then a guide rail is fastened to the door according to the markings. If you will use an electric tool for trimming, you need a metal ruler, but a wooden ruler will do if you use a hacksaw. Using clamps, the rail is pressed against the door leaf just above the marked line. Then cut off the desired part according to the markings.
You can trim the leaf from the top if it has a symmetrical or hollow pattern, and you want to remove more than 1 cm of the leaf. Then trim the leaf on both sides, measuring the same distance at the top and bottom. The procedure is not much different from trimming from below, except for the marking.
When using a circular saw, choose a fine-toothed disc: it will damage the door less, and the edges will be even. This tool is best suited for working with solid wood.
In order to correctly measure the leaf, it is necessary to know how much to cut. If you want to get rid of 5 cm of the leaf, measure 2.5 cm from the top of the leaf and the same amount from the bottom. Connect the control points with a line, then repeat on both sides. After all the work is done and the edges of the leaf are treated, the door is hung on the hinges and all the necessary fittings are attached.

- Wear safety glasses when working with power tools.

Removing part of the door leaf: planer, router, saw
Trimming a veneered interior door is carried out using a planer, router or circular saw. With this tool you can accurately perform the work. The only disadvantage is getting possible irregularities on the surface. If you use a circular saw, then you need to have certain skills. The interior door should be cut with a circular saw with tungsten carbide teeth. If you make a clean cut, then you need a disk with more teeth. To perform the work with a hand router, it is necessary to perform all actions with the utmost care. This tool leaves fewer chips.
If there are difficulties that do not allow the door to open freely. this is the reason to undercut it. This happens in a number of cases:
- After laying the flooring;
- After using a self-leveling coating;
- In the case of deformation (when the wood has sagged or swollen).
The above factors are the most common indications for this procedure.
Instructions for self-leveling
Before the work, the canvas is removed from its hinges and prepared by removing handles and other fittings from it. Cut the door on the workbench, but if you don’t have a workbench, a large, stable table will do.
If the solid wood leaf needs to fit the opening due to sagging or elevation of the floor, it is best to trim the door from below. Take 2 measures of height: at the hinge part and at the butt. To transfer the marks to the blade, deferring new dimensions from the upper edge. Make a straight line for the trimmer through 2 points. It is advisable to use a long ruler and a square to control the right angles between the edges.
Attach the guide rail to the marked line. When using a power tool, it is best to use a metal strip or ruler. If you cut the door with a hand held wood hacksaw, a guide made of straight slats will work. Press the template to the cloth by means of clamps above the marks.
To preserve the layer of varnish and veneer on a polished door, finish it with an angle grinder. The tool’s blade will leave a kerf with even edges that cannot be made with a saw. Guide the angle grinder along the guide bar. Before machining, stick a scotch tape along the marking line, and transfer the straight line to its surface.
If there is no angle grinder, the lacquer coating on the part to be removed is removed with an emery cloth, and the veneer is cut through with a sharp knife on both planes of the blade and on its edge parts. The door can then be sawn off along the guide rail.
Remove the clamps and trim the file edges with sandpaper. The veneered door should be glued with edgebanding, matching its shade to the veneer. If the solid surface is painted, varnish or paint the cut edges. Hang the door leaf on the frame, remove the warping and attach the stripped fittings.
The same sequence of work is performed when replacing the leaf: the standard dimensions of the new product can be changed in height and width. When carrying out the work, take into account what the product is assembled of.
It is possible to cut solid or laminated fiberboard panels from the bottom, if they are not panelled or have an imitation of such. If the decor is symmetrical, it is better to trim on both sides, dividing the cut length by 2. These measures are taken from each edge without disturbing the symmetry of the top and bottom veneers. The same is done if you want to reduce the standard width of the door leaf.
Frame hollow-core doors must not be shortened too much. The product consists of wooden planks of limited thickness. Leave not less than 1-1,5 cm of framing timber inside the leaf. You can shorten the door as indicated for a construction with wainscoting. at the top and bottom.
When trying to install a standard door in a small opening, the frame mouldings are shortened according to the measurements and fixed in the opening. It is necessary to adjust the size of the leaf according to the technology described above.
Solid wood blanks sometimes swell due to excessive moisture and do not fit well into the frame. You can eliminate such a problem with a planer or a grinder (a hand router). Remove the panel, put it on the workbench and trim its edge with a cutting tool, removing a few millimeters of wood shavings from the desired side. Hinge the door and try it out. If the problem persists, repeat the work.
To get an even cut of the massif when using a circular saw, you need a disk with lots of small teeth. But even with this condition it will not be possible to cut a veneer product qualitatively. For fiberboard cloth, it is better to prefer an electric jigsaw, and the work should be done with the observance of the rules protecting the veneer layer (gluing tape, cutting through the veneer).
If there is a possibility to use a manual milling machine, you should choose it for work. The tool will perform an even and clear cut, and the cutting trimmer line will not have to be treated additionally, neither on a solid product, nor on a wood-fiber board or frame model.
For proper gluing of the edge tape, use PVA glue and an iron. The glue layer should be applied to the saw cut of the leaf, let it dry. Put the tape on the edge of the door and iron through the paper with a hot iron. After cooling down, cut off the excess tape with a sharp knife, and lightly rub the edges with sandpaper.
If you decide to install a gas boiler, all requirements must be met for this in the room. In particular, the gas service will not connect the gas if the room where the boiler is located does not have the necessary minimum clearance between the door and the floor, which provides for natural air circulation.
How to trim an interior door
With horizontal cutting, given also the uncomfortable position of the hands when sawing, the hacksaw will begin to walk on the blade and the cut will not turn out even. So it is best to remove the door, but before you do it, you need to see what gap already exists, as well as whether it is even.
It happens that the door is set flat, and the floor is not quite horizontal, which creates a wedge-shaped gap, and it does not look very beautiful. So if the gap is uneven, you can solve this problem at the same time. Next, take a tape measure and mark on each side the required distance from the floor.
Almost anything can be trimmed. The only exception is the door with glass inserts, they can also be cut, but it is an order of magnitude more difficult. If you have a regular door, there are no problems.
Hinges, by means of which the door is held in the box, also vary. If the doors are old, it will be enough to open the door at 90 degrees and use a crowbar to pry it open. If the hinges are fastened with self-drilling screws, it is necessary to unscrew them with an electric screwdriver, but before this put wedges under the door, otherwise the box can be damaged.
How to do the job?
Shorten it by height
In older homes, you usually see a narrow height aisle. Modern doors in such houses do not look good at all. The change in size greatly affects the appearance of the apartment.
The height of the opening is reduced in three ways:
- With the help of a wooden bar.
Choose a timber with a cross-section of 3 cm less than the width of the door opening. Self-tapping screws or nails must be twice as long as the bar itself. It is measured so that it fits exactly into the width of the opening without any gaps.
Everything must be done correctly, because the result depends on the measurements.
The profile is measured so that it can be cut to the right length and fastened tightly with screws.
Count the number of bricks, make a mark with a pen the required height.
Narrow it in width
You can narrow the door opening by starting by marking out the sections. This is done with an aluminum rule:
- It is put on the floor and with a pencil or marker draw the lines of necessary cuts.
- Along the perimeter of the lines we put guides on the floor, the upper slope.
- Fix our construction.
- Insert the mullion profiles.
The walls should be well primed before each stage of installation. Priming is carried out abundantly, several times. This measure will ensure a good contact of the application material with the surface.
You can cut the necessary size of drywall sheets. Most often, builders use a special glue. If you don’t have it handy, ordinary plasterboard will help.
It is possible to reduce the front door, if you have all the necessary tools at hand. You need to take the appropriate measurements, calculate all the parameters.
