A door hinge has to carry the door, allow it to move freely and suit the frame preparation. Choosing one by finish alone can lead to a door that binds, sags or cannot be fitted to the existing mortises. Start with the door’s construction and use, then compare hinge type, dimensions, load guidance and installation requirements.
Quick answer: Butt hinges are a common choice for many hinged interior doors; ball-bearing versions are designed for smoother movement in applications specified by their maker. Concealed hinges hide when the door is closed, while spring hinges can provide self-closing action if selected and adjusted for that use. Pivot hinges support a door around pivot points rather than a conventional side leaf. Match the hinge to the door, frame, load, swing and existing preparation.
What are the main types of door hinges?
Butt hinges
A butt hinge has two leaves joined by a knuckle and pin. One leaf is fixed to the door and the other to the frame. Many are mortised into the door edge and jamb so the door can close nearly flush. Butt hinges are available in different sizes, materials, finishes and bearing designs. Check the manufacturer’s dimensions and load information rather than assuming that hinges of the same size have identical capacity.
Ball-bearing hinges
A ball-bearing butt hinge has bearings in the knuckle to support movement. It may be specified for heavier, frequently used or higher-demand doors, but suitability depends on the exact model, number of hinges, door construction and installation. Do not treat “ball bearing” as an automatic rating for every heavy door; check the product data and follow the maker’s guidance.
Concealed hinges
Concealed hinges are hidden when the door is shut. Some architectural systems allow adjustment in more than one direction, but they need compatible door and frame preparation. Simonswerk’s product selector lists concealed systems alongside other hinge types and shows that product series have their own load ranges and applications. The product family name alone does not confirm suitability; use the model’s technical sheet and installation instructions.
Spring or self-closing hinges
Spring hinges include a mechanism that returns the door toward a closed position. They may be used where self-closing action is needed, but the spring force, door weight, number of hinges and adjustment method must match the door and the intended use. A spring hinge is not automatically a substitute for a certified fire-door closer or other required component. For fire-rated or regulated doors, use the complete approved assembly and ask a qualified door professional.
Pivot hinges
Pivot hinges support the door at points near the top and bottom rather than along the side edge. They can allow a different visual or movement style, but the door and floor or head structure must be designed for the pivot system. The pivot position affects the swing path, clearance and hardware loads. Confirm structural support and floor conditions before choosing one.
How do you choose hinges for an interior door?
Begin with the door itself. Measure its height, width and thickness, identify its material and construction, and note whether it is solid, hollow-core, glass or a rated door. A heavy or wide door places different demands on the hinge and fasteners than a light bedroom door. Check the hinge manufacturer’s guidance for door dimensions, weight, number of hinges and fixing requirements.
Next, inspect the existing hinge position and preparation. Measure leaf height and width, corner shape, knuckle projection and screw-hole spacing. A replacement hinge must fit the mortise depth and frame layout, or the installer will need to alter the door or jamb. If an existing door binds, do not assume new hinges will fix it: the frame may be out of square, the door may have swollen, or screws may have loosened.
Choose the swing and function. A standard butt hinge opens in one direction according to its handing and installation. A pivot or specialty hinge may change the swing path. Make sure the door can clear adjacent walls, cabinets, toilet fixtures and other doors. Consider whether the door should remain open, close by itself or connect to a separate closer.
How many hinges does a door need?
Do not apply a universal hinge count without checking the product instructions. Hinge number and placement depend on door height, weight, construction, hinge model and local requirements. Some hinge specifications assume a certain installation, screw type or door material. If the door is unusually heavy, wide, frequently used or part of a fire-rated assembly, have the supplier or installer confirm the correct arrangement.
Follow the supplied template for spacing. Placing hinges too close to a door edge, using undersized screws or missing solid backing can cause loosening or damage. In a hollow-core door, the screw may not have the same holding support as in a solid stile. Do not substitute longer screws without checking what lies behind the frame; concealed wiring, pipes or glazing can be present.
What should you compare before buying?
- Hinge type and whether it matches the door and frame construction.
- Leaf dimensions, thickness, corner shape, pin type and screw layout.
- Manufacturer load guidance for the exact model and installation method.
- Door swing, clearance, self-closing or hold-open requirements.
- Material, finish and suitability for indoor, humid or exterior conditions.
- Any fire, accessibility, security or building-code requirements.
Finish is still important for appearance and corrosion resistance, especially in a damp room or near an exterior entrance. But the hinge body and its fixing method must work first. Compare the finish sample with the handle, lock and other visible fittings. Check whether the maker offers matching screws and replacement pins.
Our cabinet hinge guide covers concealed furniture hinges, which differ from architectural door hinges. For the lock and door preparation, see the mortise lock guide; the door closer guide explains closing mechanisms that may be used alongside hinges.
When should you call an installer?
Get professional help if a door is heavy, the frame is damaged, the hinge mortise needs to be cut, the door is glass or fire-rated, or the installation involves structural changes. Hinge screws carry load, and an unsupported door can fall during removal. Use a second person and suitable support even for a simple replacement; do not remove all hinges while the door is unsecured.
For a fire door or other regulated opening, components are tested as part of an assembly. Replacing a hinge with a visually similar but unapproved model can affect the door’s rating or operation. Follow the door label and manufacturer’s documentation and use a qualified professional who can maintain the listed assembly.
Common hinge problems and what they may indicate
A door that rubs at the top corner may have loose screws, a sagging leaf, a distorted frame or another alignment issue. A squeak can come from the hinge pin or dirt, but lubrication instructions vary by model and finish. A door that will not stay open may be affected by hinge alignment, building pressure, floor slope or a closer. Tightening screws can help a loose hinge, but repeated tightening into stripped wood will not restore a secure fixing.
If the door drops, drags or closes unpredictably, stop forcing it. Check for visible damage and keep people clear of a heavy or unstable door. A carpenter or door technician can assess the frame, leaf, hinges and related hardware together rather than replacing one part by guesswork.
Frequently asked questions
Are ball-bearing hinges better than regular butt hinges?
They are designed differently, but the better choice depends on the door, use and model specification. Compare the manufacturer’s load and application guidance.
Can I replace a door hinge without changing the mortise?
Yes, if the replacement matches the leaf size, corner shape, thickness, screw layout and mortise. Measure first; otherwise the door or frame may need adjustment.
Are concealed hinges suitable for every door?
No. Concealed systems need compatible door and frame preparation and have model-specific load limits. Check the technical data and installation instructions.
Can spring hinges replace a door closer?
Not automatically. The required closing device depends on the door’s use and any applicable safety or fire requirements. Follow the door assembly documentation.
How many hinges should an interior door have?
Use the hinge and door manufacturer’s recommendations for the exact door dimensions and weight. Do not rely on a count without checking the specification.
In summary: Select a hinge by the door’s weight, construction, frame preparation, swing and required function. Butt, ball-bearing, concealed, spring and pivot designs solve different problems. Check the model’s technical information and use a qualified installer for heavy, glass, fire-rated or structurally altered doors.
