Choosing the Right Door Hinges
Choosing the correct door hinge is essential for smooth operation, long-term durability and the safe support of the door.
The right hinge depends on several factors including the door weight, width and height, door construction, frequency of use, required opening angle, fire requirements and the number of hinges being installed.
A lightweight internal door has very different requirements from a heavy commercial fire door or substantial external timber door, so hinges should always be selected for the particular application.
Internal Door Hinges
Standard internal timber doors are commonly fitted with butt hinges or ball bearing hinges.
Ball bearing hinges incorporate bearings around the hinge knuckle to reduce friction and provide smoother movement, making them particularly useful on heavier or more frequently used doors.
The size, grade and number of hinges should be selected according to the weight and dimensions of the door.
Ball Bearing Hinges
Ball bearing hinges are widely used on residential and commercial doors where smooth operation and durability are required.
The bearings reduce friction between the moving sections of the hinge, helping the door operate smoothly even with frequent use.
They are available in different sizes, performance grades and finishes, allowing the hinge to be selected according to both technical requirements and the surrounding door furniture.
Commercial & Heavy-Duty Hinges
Commercial doors can be significantly heavier and may operate far more frequently than a typical domestic internal door.
For these applications, graded heavy-duty hinges should be selected according to the required door weight, usage and relevant performance standard.
Higher-grade hinges are commonly used on entrance doors, commercial buildings, hotels, schools, healthcare facilities and other high-traffic environments.
Always check the manufacturer's stated load capacity and installation configuration rather than selecting a hinge purely by its physical size.
Fire Door Hinges
Hinges are an important component within a fire-rated doorset.
Where hinges are intended for an FD30, FD60 or other fire-door application, the individual hinge must have suitable supporting test or certification evidence and be installed in accordance with the relevant doorset specification.
The fire performance of a door depends on the complete assembly, including the door leaf, frame, hinges, locks, closers, seals and installation.
Where required, compatible intumescent hinge protection should also be installed in accordance with the hinge and doorset evidence.
Concealed Hinges
A concealed hinge is recessed into the door and frame so that the hinge is largely hidden when the door is closed.
This creates a cleaner, more minimal appearance and makes concealed hinges particularly popular for flush doors, contemporary interiors and high-end architectural projects.
Selected concealed hinges also offer 3D adjustment, allowing the position of the door to be fine-tuned after installation.
Because concealed hinges require accurate machining, always check the required door thickness, hinge dimensions, load capacity and installation template before cutting the door or frame.
T Hinges
T hinges are commonly used on traditional plank doors, ledge-and-brace doors, gates and other traditional joinery.
When opened, their shape resembles the letter T, with the long strap extending across the face of the door.
Traditional styles include Penny End, Arrow Head and black cast T hinges, with longer versions available for substantial timber doors and gates.
They work particularly well alongside traditional thumb latches and other forged architectural ironmongery.
Parliament Hinges
A Parliament hinge is designed to project the door further away from the frame as it opens.
This can allow a door to swing clear of deep architraves, reveals, shutters or other architectural features.
Because the increased projection changes the forces acting on the hinge and fixings, Parliament hinges must be correctly sized for the door and installation.
Rising Butt Hinges
A rising butt hinge lifts the door slightly as it is opened.
They can be useful where additional floor clearance is required during the opening movement.
Rising butt hinges are generally handed, so it is important to identify whether a left- or right-handed hinge is required before ordering.
Choosing a Hinge Finish
Where hinges remain visible, their finish can be coordinated with the surrounding architectural hardware.
Traditional interiors often suit Aged Brass, Bronze, Black, Beeswax and Pewter, while Satin Brass, Chrome, Nickel and Stainless Steel can complement contemporary interiors.
For external or highly exposed locations, check both the hinge material and the manufacturer's stated suitability for the environment rather than choosing solely by appearance.
Frequently Asked Questions
What type of hinge do I need for an internal door?
A standard timber internal door will commonly use butt hinges or ball bearing hinges.
The correct size and grade depends on the weight, dimensions and frequency of use of the door.
How many hinges should a door have?
The number required depends on the door weight, height, width and hinge specification.
Many standard doors use three hinges, but heavier or unusually tall doors may require a different arrangement.
Always follow the hinge manufacturer's load and installation guidance.
What is a ball bearing hinge?
A ball bearing hinge incorporates bearings around the hinge knuckle to reduce friction.
This helps provide smooth operation and makes ball bearing hinges particularly suitable for heavier or frequently used doors.
What hinge do I need for a fire door?
Use hinges that are specifically supported for the required fire-door application and installation.
The complete doorset specification should determine the hinge type, number, fixings and any required intumescent protection.
What is a concealed hinge?
A concealed hinge is recessed into the door and frame and is largely hidden when the door is closed.
They are commonly used on flush doors and contemporary architectural interiors.
What is the difference between Grade 11 and Grade 13 hinges?
The grade forms part of the hinge's performance classification.
Higher-grade hinges may be designed for heavier or more demanding applications, but always check the individual product's certified load capacity and intended use rather than relying on the grade number alone.
What are T hinges used for?
T hinges are commonly used on traditional plank doors, ledge-and-brace doors, gates and similar timber joinery.
Their long strap spreads the fixing across the face of the door.
What are Parliament hinges used for?
Parliament hinges allow a door to project further away from the frame as it opens.
They are useful where a door needs to clear deep architraves, shutters or other obstructions.
