Internal Door

Hanging a door by yourself can be a daunting task, but with the right tools and a clear understanding of the process, it’s entirely feasible to do it on your own. This guide will walk you through the essential steps of hanging a door, as well as answer some frequently asked questions to help you handle this project with confidence.

Step-by-Step Guide to Hanging a Door

1. Choose the Right Door and Tools

  • Door: Ensure the door you select is the correct size and style for your frame.
  • Tools: You will need a tape measure, pencil, level, screwdriver, drill, chisel, hammer, and possibly a plane.

2. Measure and Mark the Door

  • Measure the existing door frame and the new door to make sure the door fits well. If necessary, mark where you might need to trim the door.

3. Prepare the Door

  • If your door needs trimming, use a plane to shave off excess wood carefully. Ensure the door is the correct size, with about 2mm gap at the top and sides.

4. Mark Hinge Positions

  • Place the door in the frame and use a pencil to mark the hinge positions. Make sure the door opens and closes freely without binding on the frame.

5. Cut Hinge Recesses

  • Use a chisel to cut out the hinge recesses on the door. These should be shallow enough for the hinge to sit flush with the wood.

6. Attach the Hinges

  • Screw the hinges onto the door first, then align them with the frame. Use your pencil marks as a guide.

7. Hang the Door

  • With the help of another person, lift the door and place the hinges against the frame. Screw the hinges into the frame, ensuring the door is level.

8. Test the Swing of the Door

  • Check that the door swings open and closes smoothly. Make adjustments to the hinges if necessary.

9. Install the Door Handle and Lock

10. Final Checks

  • Ensure all screws are tight and the door operates as it should. You might need to add a door stopper to prevent the door from hitting the wall.

Frequently Asked Questions (FAQs)

Q1: How do I know if I need to plane the door? A: If the door doesn’t fit into the frame with a slight gap around the edges (typically about 2mm), it needs to be planed down.

Q2: What should I do if the hinges are old and worn out? A: Replace old hinges with new ones of the same size. This will ensure better support and functionality for your new door.

Q3: Can I reuse the existing hinge cuts on a new door? A: Yes, if the new door is the same size as the old one. However, ensure that the hinge cuts are clean and deep enough for the new hinges.

Q4: How can I ensure the door is hung straight? A: Use a level to check that the door is perfectly vertical (plumb) when you attach it. Adjust as necessary before tightening all screws.

Q5: What type of screws should I use? A: Use screws that are long enough to go through the door and into the frame securely, typically at least 1 inch long.


Hanging a door might seem complex, but following these steps will make the process smoother and ensure professional results. Whether you’re replacing an old door or installing a new one, taking the time to do it correctly will pay off in the functionality and appearance of your door. Remember, patience and precision are your best tools in this project.
