How to Adjust a Door Hinge

Adjusting a door hinge is the most precise way to fix a door that sticks, has gaps, swings on its own, or doesn't latch properly. Small hinge adjustments can solve problems that seem much more complex. Here's how to do it.

Why Adjust a Door Hinge?

Hinges control the exact position of the door in the frame. By adjusting hinge depth, position, or adding shims, you can move the door up, down, in, or out to fix:

• Door sticking at the top or latch corner
• Gaps on the hinge side or latch side
• Door swinging open or closed by itself
• Latch not aligning with strike plate
• Door dragging on the floor

Understanding How Hinges Affect Door Position

• Adding a shim behind the top hinge → moves the top of the door toward the latch side (closes hinge-side gap at top, opens latch-side gap at top)
• Adding a shim behind the bottom hinge → moves the bottom of the door toward the latch side
• Deepening the top hinge mortise → moves the top of the door toward the hinge side
• Deepening the bottom hinge mortise → moves the bottom of the door toward the hinge side

Method 1: Add Hinge Shims (Move Door Away from Hinge Side)

Shims go behind the hinge leaf to push the door away from the hinge side. This is the most common adjustment.

1. Remove the hinge screws from the frame side (leave door side attached)
2. Slide a shim behind the hinge leaf
3. Trim the shim to fit within the mortise
4. Replace the screws through the shim
5. Test the door and add more shims if needed

Method 2: Deepen the Hinge Mortise (Move Door Toward Hinge Side)

If the door needs to move toward the hinge side, deepen the mortise with a chisel.

1. Remove the hinge and mark the new depth with a pencil
2. Score the outline with a utility knife
3. Chisel out thin layers until the correct depth is reached
4. Reinstall the hinge and test

Method 3: Use Longer Screws to Pull Door Tighter

Replace standard 3/4" hinge screws with 3" screws that reach the wall stud. This pulls the hinge — and the door — tighter to the frame, which can close small hinge-side gaps.

Method 4: Bend the Hinge Pin for Friction

For a door that swings on its own, remove a hinge pin and give it a very slight bend (1–2mm). The added friction holds the door at any position.

Quick Reference: Which Hinge to Adjust

• Door sticks at top latch corner → tighten or shim bottom hinge
• Door sticks at bottom latch corner → tighten or shim top hinge
• Gap on hinge side at top → deepen top hinge mortise
• Gap on latch side → add shim behind one or both hinges
• Door swings open → shim top hinge or bend hinge pin
