To fit a door that is too big, you will need to trim the slab using a circular saw, hand saw, or block plane. Always ensure there is a 2-to-3 mm gap around the perimeter of the door so it can swing freely, and be careful not to remove too much material from hollow-core doors.
If the difference between the door and the frame is less than one inch in width, then you can fix it by adjusting just one side of the frame. If the difference is more than one inch, then you will need to furr out both sides. If the issue is height, not width, then you will need to adjust the top jamb.

To stop a door from opening all the way—especially if it's hitting a wall or furniture—installing a hinge-pin door stop is usually the quickest and most effective DIY method.
A door stop is hardware that controls how far a door can open. By setting a fixed angle—commonly 90° or 120°—it prevents the door from swinging freely and causing damage. Unlike quick fixes, a door stop hinge is intentional, durable, and designed to keep both the door and surrounding surfaces safe under daily use.
The best tool for shaving a door depends on how much wood needs to be removed. For major trimming, a circular saw or power planer works best. For minor shaving and sticking issues, a specialized tool like the RYOBI Wood Door Trimmer or a simple hand tool like a block plane is ideal.

How Do You Shorten a Door Without Removing It? There are two main ways to shorten a door: trimming the bottom or making small changes to the sides. Trimming from the Bottom: If the door just touches the floor, you can often fix this by gently sanding the bottom edge without removing it from the hinges.
Planing: For Major Swelling
If sanding doesn't quite do the trick, you might need to bring out the big guns—a planer. A hand planer allows you to shave off larger amounts of wood, particularly useful if your door has swelled significantly.
Shaving a door to fit involves removing it from its hinges, marking the exact excess, cutting it with a circular saw or hand plane, and sealing the exposed wood. Always apply painter's tape along the cut line to prevent wood veneer from splintering.

Trimming Your Internal Door Down To Size
The sides of the door usually shouldn't need a whole lot of wood removing, and it's a reasonably simple job – as long as you've got a steady hand! Use a hand plane (or a power plane) to shave off equal amounts from each side, using the pencil lines you marked earlier.
