Overview
This project builds a solid interior wooden door approximately 80 ร 200 cm.
The guide focuses on building a strong door frame, fitting panels and installing hinges accurately.
Difficulty: Hard
Estimated Time: 12โ20 hours
Materials
- Hardwood or suitable door timber
- Door panels
- Wood glue
- Hinges
- Door handle and latch
- Screws
- Sandpaper
- Wood finish
Tools
- Measuring tape
- Carpenter’s square
- Saw
- Chisels
- Drill
- Clamps
- Router
- Sander
- Level
Recommended Dimensions
- Door width: 80 cm
- Door height: 200 cm
- Door thickness: approximately 35โ45 mm
- Panel thickness: approximately 15โ20 mm
- Typical clearance depends on the actual frame
- Frame corners: 90ยฐ
Tips
- Measure the existing door opening before building the door.
- Do not assume the opening is perfectly square.
- Build the door slightly according to the required finished clearance.
- Use strong hinges appropriate for the door weight.
- Test-fit the door before applying the finish.
Steps
Step 1 โ Measure the Door Opening
Measure the opening at the top, middle and bottom.
Measure the height on both sides.
Record the smallest measurements.
Tip: Old door openings are often not perfectly square. Building to the largest measurement without accounting for the smallest one can result in a door that does not fit.
Step 2 โ Plan the Door
Create a drawing showing the stiles, rails and panels.
Use the target size of approximately 80 ร 200 cm only if it matches the actual opening.
Tip: Leave the required clearance around the door rather than trying to make the door exactly the same size as the opening.
Step 3 โ Prepare the Frame Pieces
Cut the vertical stiles and horizontal rails.
Keep every cut square.
Mark the inside and outside faces.
Tip: Label every component before cutting joinery. This prevents accidentally reversing a piece.
Step 4 โ Cut the Joinery
Use suitable mortise-and-tenon or similar strong furniture joints.
Cut the mortises carefully.
Test each tenon individually.
Tip: A furniture joint should fit firmly by hand without requiring excessive force.
Step 5 โ Prepare the Panels
Cut the door panels to fit their openings.
If using solid wood, allow room for natural movement.
Do not glue solid panels rigidly into a frame on all sides.
Tip: Leave the appropriate expansion space based on the actual wood and construction method.
Step 6 โ Dry Assemble the Door
Assemble the complete door without glue.
Check:
- Overall dimensions
- Diagonals
- Panel fit
- Square corners
Tip: This is the last easy opportunity to correct the design before glue makes the structure permanent.
Step 7 โ Glue the Door
Apply glue to the structural joints.
Assemble the frame.
Clamp it.
Measure the diagonals again.
Allow the glue to cure.
Tip: Use clamps gradually from multiple directions rather than applying extreme pressure from one side.
Step 8 โ Fit the Hinges
Mark hinge positions.
For a heavy door, use appropriately rated hinges and distribute them according to the hardware manufacturer’s recommendations.
Recess the hinges carefully if required.
Tip: Test the hinge depth using scrap wood first.
Step 9 โ Sand and Finish
Sand progressively from 120 to 220 grit.
Move the door into a clean, dry and well-ventilated room for finishing.
Apply thin coats.
Tip: Finish all accessible surfaces consistently to reduce uneven moisture absorption.
Step 10 โ Final Installation
Install the door temporarily.
Check the swing.
Check the gaps.
Install the latch and handle.
Adjust the hinges if necessary.
Tip: Never force the door closed during the first test. Find the exact point of interference and correct it.
