How Short A Door Inside Should Be Trimmed?

Trimming interior doors can be a simple process that involves using a pencil and straightedge to mark the area for trimming. Subtract 0.25 inches (6.4 mm) from both the length and height of the door frame to ensure enough space around the door. To trim the width, remove equal amounts of door from both sides. If the door drags on the floor or is installed under carpeting, it may be necessary to trim off the bottoms.

To trim a wood door, take the measurements of the door and decide how much you wish to cut down by. Remember to only remove enough to free up the movement of your interior. If you are trimming an existing door, identify differences in the gaps around the door or look for areas on or around the door that show. When trimming a hollow core door, take off less than an inch off each side to avoid cutting into the void beyond the frame.

A clean, efficient way to measure, mark, cut, and fill a hollow-core door is to follow a step-by-step guide. Measure the door frame and draw a line of reference before securing the door to the frame. Order doors to a smaller height and trim less to maintain proportionality. It is generally recommended to remove no more than 1 inch from the bottom of a hollow core door to ensure it maintains its shape.

How much trim do I need for an interior door?

Vertical trim elements like door and window casings should be smaller and less hefty than baseboards. A good rule of thumb is to keep them at about 50% of the height of the baseboard. This rule is also applicable to crown sizing, but there are many variables like profile and picture rail. To make a crown sizing easier, purchase foot-long pieces of different sizes and profiles and construct mock-ups in the room. This is a good process for selecting all trim elements, as most trim is readily available and inexpensive. The Rule of Thirds is a popular method for selecting trim elements.

Can you cut 2 inches off a door?

The trim of a door depends on the material used, with solid wood doors being easier to trim due to their uniformity throughout. Some doors may only have a solid core for an inch around the sides before becoming hollow. It is generally recommended not to trim more than two inches off any door to avoid damaging it. Hollow-core doors have a strong outer frame at the top, bottom, and sides, making them suitable for trimming.

However, it is crucial not to cut too much away, as this could damage the structural integrity and require replacing the outer frame. It is recommended to consult the manufacturer or product finishing instructions to avoid significant damage or the need for a new door.
