8 Simple Step-by-step Guidelines on How to Install Hinges on a Door Frame:

Step 1: Measure and Mark the Hinge Locations

The first crucial step is to accurately determine where the hinges will go on the door frame, also known as the jamb. A standard practice is to place the top hinge 7 inches from the top of the door jamb and the bottom hinge 11 inches from the floor. If you are installing a third hinge for added support, it should be centered between the top and bottom hinges. Use your tape measure to find these spots and make precise marks with a pencil. A carpenter’s square will help ensure your marks are perfectly level and straight.

Once you have your primary marks, hold the hinge in place against the jamb. The barrel of the hinge should point in the direction the door will swing open. Carefully trace the outline of the hinge onto the door frame with your sharp pencil. This outline will serve as the guide for creating the mortise, the recessed area where the hinge will sit flush with the frame. Double-check your measurements and outlines before proceeding to the next step, as accuracy here prevents issues later on.

Step 2: Score the Outline of the Hinge

With the hinge outline clearly marked on the door frame, it’s time to create a clean boundary for your mortise. Take your utility knife and carefully score along the pencil lines you traced. Press firmly enough to cut into the top layer of wood, making several shallow passes rather than one deep one. This technique prevents the wood from splintering or chipping when you begin to chisel it out, ensuring a neat and professional finish for your hinge placement.

The purpose of scoring is to define the edges of the mortise precisely. This step is especially important on finished or painted wood, as it helps maintain a crisp edge. Go over each line two or three times to create a distinct groove. This simple action significantly improves the quality of your work by giving the chisel a clear path to follow, which ultimately helps the hinge plate sit perfectly flush within the frame.

Step 3: Chisel Out the Mortise

Now you will create the recess, or mortise, for the hinge plate. Place the flat side of your sharp wood chisel on the scored line at a slight angle. Gently tap the end of the chisel with a hammer or mallet to begin removing wood from inside the traced outline. Work in small increments, moving across the grain of the wood. The goal is to remove thin layers of wood at a time to avoid going too deep. The depth of the mortise should match the thickness of the hinge plate exactly.

To check your progress, periodically place the hinge plate into the mortise to see if it sits flush with the surface of the door frame. If it’s too shallow, the door won’t close properly. If it’s too deep, it will create an uneven gap. Continue to carefully shave away small amounts of wood until the hinge fits perfectly. Patience is key here; rushing can lead to removing too much wood, which is much harder to fix than simply chiseling a little more.

Step 4: Mark and Drill Pilot Holes

Once the mortise is correctly chiseled out and the hinge sits perfectly flush, it’s time to prepare for the screws. Place the hinge back into the mortise and hold it firmly in place. Use your pencil or an awl to mark the center of each screw hole on the door frame. These marks are essential for ensuring the screws go in straight and secure the hinge properly without splitting the wood. Accuracy is important, so make sure the hinge doesn’t shift while you are marking the holes.

Next, select a drill bit that is slightly smaller in diameter than the hinge screws you will be using. This prevents the wood from splitting when you drive the screws in. Carefully drill pilot holes at each of the marked spots. Be sure to drill straight and only as deep as the screw’s length. These pilot holes will make it much easier to install the screws and will guide them into the correct position, resulting in a stronger and more stable installation.

Step 5: Attach the Hinges to the Door Frame

With the pilot holes drilled, you can now securely attach the hinge plates to the door frame. Position the hinge leaf back into its mortise, aligning the holes in the hinge with the pilot holes you just drilled. Insert the provided screws into each hole. It’s best to start each screw by hand for a few turns to ensure they are properly threaded before using a drill or screwdriver. This prevents cross-threading, which can damage both the screw and the wood.

Using your drill set to a low torque setting or a Phillips head screwdriver, drive the screws in until they are snug and the hinge plate is held firmly against the frame. Avoid over-tightening the screws, as this can strip the wood and weaken the connection. The screw heads should sit flush with the surface of the hinge plate. Once all screws are in place for each hinge, give them a final check to ensure they are secure.

Step 6: Prepare the Door for Hinge Installation

After installing the hinges on the frame, the next step is to prepare the door itself. This involves creating corresponding mortises on the edge of the door. To do this correctly, you will need an assistant to help you hold the door in the frame, or you can use shims or wedges to prop it up to the correct height. Place the door into the opening, ensuring the gap at the top is even, typically about 1/8 of an inch.

Once the door is positioned correctly, the hinge plates on the frame will rest against the edge of the door. Use your pencil to trace the outline of each hinge onto the door’s edge. These marks show exactly where you need to create the mortises on the door. After marking, you can remove the door from the frame and lay it on a stable surface to begin the process of scoring and chiseling out these new mortises, just as you did on the frame.

Step 7: Chisel the Mortises on the Door

With the hinge locations marked on the edge of the door, you can now repeat the chiseling process. Start by carefully scoring the pencil outlines with your utility knife to prevent the wood from splintering. This step is just as important on the door as it was on the frame for achieving a clean, professional finish. Take your time to ensure the scored lines are straight and follow your traced marks accurately.

Next, use your sharp chisel and mallet to carefully remove the wood inside the scored area. Work slowly, taking off thin layers at a time until the mortise is the correct depth. The goal is for the hinge plate to sit perfectly flush with the edge of the door. Use the hinge itself as a guide, frequently checking the depth as you work. A perfectly cut mortise ensures the door will align correctly with the frame and close smoothly.

Step 8: Hang the Door

The final step is to hang the door. First, attach the remaining hinge leaves to the mortises on the door, drilling pilot holes and securing them with screws just as you did on the frame. With all hinge parts attached, you are ready to connect them. Carefully lift the door and align the hinge knuckles on the door with those on the frame. Have a helper assist you with this part, as doors can be heavy and awkward to handle alone.

Slide the hinge pins into the knuckles to connect the two halves of each hinge. You may need to gently tap the top of the pins with a hammer to set them fully in place. Once all pins are inserted, test the door by slowly opening and closing it several times. It should swing freely without sticking or rubbing against the frame. Check the gaps around the door to ensure they are even. If everything looks good, your installation is complete. Following these steps on how to install hinges on a door frame will ensure a secure and functional door for your home.

Safety Tips

Always wear safety glasses to protect your eyes from wood chips and dust, especially when chiseling and drilling. Ensure your wood chisel is sharp; a dull chisel is more likely to slip and cause injury than a sharp one. Use a drill with a clutch setting to avoid over-tightening screws and stripping the wood, which could compromise the hinge’s stability. When lifting and positioning the door, get help from another person to prevent back strain or dropping the door. Keep your fingers clear of the hinge area when closing the door for the first time.

How Much Will It Cost?

The cost of installing door hinges yourself is quite low. A set of standard interior door hinges typically costs between $5 and $20. If you already own the necessary tools like a drill, chisel, and tape measure, your only expense will be the hinges and screws. If you need to hire a professional, the cost will be higher.

A handyman might charge between $75 and $150 for the labor to hang a single door, which includes installing the hinges. The final price can vary depending on your location, the complexity of the job, and the professional’s hourly rate.

Frequently Asked Questions

Q1: What Are The Standard Hinge Positions On A Door?

A1: For most interior doors, the standard placement is to position the top hinge 7 inches down from the top of the door frame and the bottom hinge 11 inches up from the floor. If a third hinge is used for extra support, it is typically centered between the top and bottom hinges. These measurements ensure the door has proper balance and support.

Q2: How Deep Should The Hinge Mortise Be?

A2: The mortise should be chiseled to a depth that is exactly equal to the thickness of the hinge plate (the flat part that gets screwed in). When the hinge is placed in the mortise, it should sit perfectly flush with the surface of the wood. This ensures that there is a proper and even gap between the door and the frame when the door is closed.
