The Complete Guide to Door Hinges in Australia (2026): Types, Sizes & How to Choose the Right Hinge

1. Introduction

Nobody walks into a beautifully finished home and compliments the hinges. And that's exactly the point — good hinges are invisible. They let a door swing silently, close cleanly, and sit perfectly in its frame for decades without ever asking for attention.

Bad hinges, on the other hand, announce themselves constantly. The squeak every morning. The door that's dropped and now scrapes the carpet. The latch that no longer lines up. The external door with rust bleeding down the stile after two coastal winters.

A standard door opens and closes tens of thousands of times over its life, and every single cycle runs through the hinges. They're among the cheapest components on the door — and among the most consequential. This guide covers everything you need to choose them well: every hinge type used in Australian homes and commercial buildings, standard sizes, how many hinges each door needs, materials, finishes, fire door requirements, and the mistakes we see most often.

2. What Is a Door Hinge?

A door hinge is a mechanical bearing that connects the door to its frame and constrains it to rotate around a single fixed axis. The classic butt hinge has three working parts:

• Two leaves — flat plates, one screwed to the door edge, one to the frame (jamb), usually mortised (recessed) flush into each.
• Knuckles — the interlocking barrel segments formed along the edge of each leaf.
• The pin — the rod running through the knuckles that everything rotates around.

Why hinge quality affects door operation. Every gram of the door hangs off the hinges, and every movement grinds through them. Quality shows up in three places: the precision of the knuckle machining (sloppy tolerances mean a door that rattles and wanders), the bearing design (plain metal-on-metal contact wears; ball bearings don't), and the thickness and fixing of the leaves (thin leaves flex, and flexing doors never sit right). A cheap hinge and a quality hinge look nearly identical on day one. They do not look identical on day three thousand.

Common causes of sagging doors. When a door drops in its frame and starts binding or missing its latch, the usual suspects are:

• Worn knuckles or pin — plain-bearing hinges grinding themselves loose over years of use.
• Loose or stripped screws — often because screws were too short, or driven into soft reveal lining instead of solid frame timber.
• Too few hinges — two hinges carrying a door that needed three, letting the door bow and lever its top hinge loose.
• Undersized hinges — a heavy solid-core door hung on lightweight hinges.
• Frame movement — timber shrinkage and building settlement, which good hinges can't prevent but adjustable hinges (see concealed hinges below) can compensate for.

Almost every sagging door traces back to one of these — and almost every one is preventable at specification time.

3. Types of Door Hinges

Butt Hinges

The standard door hinge and the baseline everything else is measured against: two rectangular leaves, interlocking knuckles, a central pin, mortised into the door and frame edges. Simple, strong, economical. For light internal doors in low-traffic locations, a quality plain butt hinge does the job. For everything else, one of the upgrades below is usually worth the small extra cost.

Ball Bearing Hinges

A butt hinge with bearing races seated between the knuckles, so the door rides on rolling bearings instead of grinding metal on metal. The result: fingertip-smooth operation, no squeaking, and almost no wear — the hinge feels the same in year twenty as day one. The standard choice for external doors, solid-core doors, high-traffic openings and any door fitted with a closer. Many builders now fit them throughout as a default. 

Parliament Hinges

Wide, often decoratively shaped leaves with a knuckle that projects well clear of the door face. That projection moves the pivot point outward so the door can swing a full 180° — clearing architraves and folding flat against the adjacent wall. The classic choice for French doors and doors opening onto verandahs and patios.

Loose Pin Hinges

A butt hinge whose pin taps up and out of the barrel, letting you lift the door off without touching a screw — invaluable for painting, trimming doors, and moving furniture. Ideal for internal doors. The critical rule: never fit them where the knuckle is accessible from the non-secure side, because a removable pin is a removable door. 

Fixed Pin Hinges

The security counterpart: the pin is permanently retained in the barrel and cannot be driven out. Essential on outward-opening external doors, where the hinge knuckles face the outside world — with loose pins fitted, an intruder can remove the pins and lift the door away, deadbolt and all. Fixed pins close that gap completely. 

Lift-Off Hinges

Made in two separable halves — a fixed pin on the frame half, a hollow barrel on the door half — so the door lifts straight off vertically with no tools at all. Perfect for doors removed regularly: access panels, service cupboards, joinery, renovation work. Note that lift-off hinges are handed (left or right), and ordering the wrong hand is the most common mistake made with them.

Concealed Hinges

Mortised entirely into the door edge and frame, completely invisible when the door is closed — just a clean shadow line. Modern concealed hinges are 3D adjustable after hanging (height, side-to-side and depth), which is how flush, shadow-line doors achieve those perfectly even margins. The hinge of choice for minimalist interiors, frameless door systems and premium contemporary entries. 

Pivot Hinges

A different philosophy entirely: the door rotates on pivot points at the floor and head, sending its weight straight down into the structure instead of hanging off the jamb. This is what makes oversized and extra-heavy statement doors possible — wide entrance panels in solid timber or steel that no butt hinge could carry. Available as offset pivots (door behaves conventionally) or centre pivots (the dramatic rotating-panel look).

Spring Hinges

A coiled torsion spring inside the barrel turns any door into a self-closing door — no overhead closer required. Tension is adjustable to suit the door's weight and exposure. Standard applications include garage-to-house doors, gates, and commercial passage doors; double-action versions swing both ways and return to centre (the café door). 

4. Door Hinge Sizes Explained

Australian butt hinges are described by two numbers: height × width (the width measured across both leaves when the hinge is open flat), in millimetres. Where each common size fits:

• 75 × 50 mm — lightweight duty: hollow-core internal doors, cupboard and joinery doors, secondary applications. Not for solid or external doors.
• 100 × 75 mm — the Australian residential standard. Suits solid-core internal doors and standard external doors, and standardising on this size across a build simplifies ordering and door prep.
• 100 × 100 mm — the same height with a wider throw. The extra leaf width pushes the knuckle further from the door face, helping doors clear thicker door leaves, deeper rebates or larger architraves (the same logic broad butt and parliament hinges take further).
• 125 × 100 mm — heavy-duty territory: tall, heavy or wide doors, commercial doors, and entrance doors beyond standard dimensions.
• 150 × 100 mm — very heavy and oversized doors, and demanding commercial applications.

Two rules sit above the size chart. First, always check the manufacturer's stated door weight capacity for the specific hinge — construction and bearing type matter as much as the leaf dimensions, and ratings generally assume three hinges fitted. Second, door thickness matters: the hinge must be wide enough that, when mortised, the door clears its frame and architraves through the full swing.

5. How Many Hinges Does a Door Need?

The old rule of "two hinges per door" belongs to an era of lighter doors. Current Australian practice:

The third hinge on a standard door does more than share weight: positioned centrally, it resists the door bowing along its length over time — one of the quiet reasons quality builds fit three as standard even on ordinary internal doors.

Placement convention: top hinge roughly 150–180 mm down from the head, bottom hinge roughly 200–250 mm up from the floor, remaining hinges spaced evenly between. Follow the doorset manufacturer's guidance where one exists — especially on fire doors, where hinge quantity and position form part of the tested assembly.

6. Ball Bearing vs Standard Hinges

The single most common hinge upgrade decision, so it's worth a proper comparison:

The honest verdict: for light internal doors in low-traffic spots, a quality standard butt is perfectly adequate. For everything else, the ball bearing premium is one of the best-value upgrades in door hardware — it's the difference between hinges you replace and hinges you forget.

7. Best Materials

The material determines how a hinge handles load, weather and time. The main options in the Australian market:

Solid Brass. A premium traditional material that doesn't rust — brass corrodes to a stable patina rather than flaking like steel. Naturally suited to coastal environments, heritage joinery and decorative applications, and it takes plated and polished finishes beautifully. Softer than steel, so respect weight ratings on heavy doors.

Stainless Steel 304. The general-purpose stainless grade: strong, durable and corrosion-resistant for the vast majority of internal and external applications. The default recommendation for external doors in most Australian locations.

Stainless Steel 316. Marine-grade stainless, with added molybdenum for superior resistance to salt corrosion. The right specification within coastal zones, around pools, and in any salt-air environment where 304 can eventually show tea staining. If the house can hear the surf, specify 316 — the same logic behind 316 stainless lever ranges for coastal homes.

Mild Steel. The economical choice, always supplied plated or coated (zinc, brass or paint finishes). Entirely adequate for internal doors in dry environments; not for external or humid locations, where any coating breach lets rust take hold.

Zinc Alloy. Cast zinc suits decorative and light-duty hinges where intricate shapes are wanted at a sharp price. Fine for light internal and cabinet applications; for structural door duty, steel, stainless or brass are the better engineering choices.

Quick selector: internal dry areas — mild steel or brass; external general — stainless 304 or brass; coastal/pool — stainless 316; heavy duty — stainless or heavy-gauge steel ball bearing patterns; decorative/heritage — solid brass.

8. Choosing the Right Finish

Hinges are jewellery you're not supposed to notice — which is precisely why a mismatched finish stands out. The contemporary Australian palette:

• Matt Black — the dominant modern choice; pairs with black levers, pulls and frames across almost every current interior style.
• Satin Brass — warm and current; the soft-gold look without polished brass formality.
• Polished Brass — traditional, formal, and right at home in heritage and classic interiors.
• Brushed Nickel / Satin Nickel — soft silver tones that hide fingerprints and suit transitional interiors.
• Graphite — deep charcoal-grey; a softer alternative to full black.
• Gunmetal — dark, slightly warm metallic; strong with timber doors.
• Chrome (polished or satin) — crisp, classic, and among the most durable plated finishes.
• Stainless Steel — the honest engineering finish; standard for external and coastal work.
• White — disappears against white-painted doors and frames, the original "invisible hinge" trick.

Matching hardware for a cohesive look. The rule is simple: the hinge finish should match the door lever or pull on the same door, and ideally the door stop, flush bolts and nearby cabinet hardware too. Brands like Tradco, Zanda and Iver produce hinges in the same finish families as their lever and pull ranges, so a whole doorset — hinge, lever, latch, stop — can be specified as one coordinated kit. Two practical notes: finishes with the same name can vary in tone between brands, so where possible keep each door's hardware within one brand's finish system; and living finishes (raw bronze, unlacquered brass) patina over time by design — pair them with each other, not with stable plated finishes that won't age alongside them.

Finish durability varies too: check the warranty on the specific product. Tradco, for example, backs Chrome Plated, Polished Nickel, Rumbled Nickel and Satin Chrome with a lifetime finish warranty, with other finishes covered under Australian Consumer Law.

9. Internal vs External Door Hinges

Internal doors live an easy life: no weather, moderate weights, high cycle counts on some doors. The specification is straightforward —

• Standard butt hinges for light, low-traffic doors, in a finish matched to the door lever.
• Ball bearing hinges for solid-core doors, main-traffic doors, and anywhere long-term smoothness matters. Loose pin versions add easy door removal for internal use.
• 100 × 75 mm, three per door, remains the safe default.

External doors face weather, weight and security all at once:

• Stainless steel (304 generally, 316 coastal) or solid brass for corrosion resistance — mild steel hinges outdoors are a rust stain waiting to happen.
• Ball bearing barrels, because entry doors are heavy and heavily used, and often carry closers.
• Security considerations: fixed pins on any door whose knuckles face outside, and security-stud patterns where the threat justifies them. The strongest deadbolt is only as good as the hinge edge of the same door.
• Salt, pool chemicals and coastal air accelerate everything — inspect external hinges as part of normal home maintenance and rinse salt exposure periodically.

10. Fire Rated Hinges

Fire doors are life-safety equipment, and the hinges are part of the system — not an accessory to it.

Fire certification. A fire door achieves its rating as a complete tested assembly: door leaf, frame, seals and hardware together. Hinges used on a fire door must be approved for that use as part of a compliant fire door assembly — the hinge is tested with the doorset, and substituting an untested hinge can void the door's compliance entirely.

Intumescent requirements (where applicable). Some fire door assemblies require intumescent protection at the hinges — material that expands under heat to seal gaps and insulate the hardware recesses. Whether it's required, and in what form, is dictated by the doorset's tested configuration.

Why not every hinge is suitable. Fire door hinges must maintain the door's position under fire conditions for the rated period. Ordinary hinges — light-gauge leaves, low-melting-point components, uncertified construction — aren't demonstrated to do that. Looks-the-same is not tested-the-same.

The practical rule: on any fire door — garage-to-dwelling doors, multi-residential entry doors, commercial fire doors — use hinges specified by the fire door manufacturer or confirmed as approved for the assembly, fitted in the quantity and positions the certification requires. If you're unsure whether a hinge is fire-door compliant, ask before you buy. This is the one hinge decision where "close enough" can carry legal and life-safety consequences.

11. Common Mistakes

The hinge problems we're asked to fix almost always trace back to one of these:

1. Wrong hinge size. A heavy solid-core door on 75 × 50 mm hinges is a sag in progress. Match size and weight rating to the actual door.
2. Using only two hinges. The third hinge shares load and stops the door bowing. Two hinges on anything but the lightest door is false economy.
3. Mixing finishes. Chrome hinges under a matt black lever is the hardware equivalent of odd socks. Specify the door as a set.
4. Choosing indoor hinges outside. Plated mild steel outdoors rusts — often within a couple of seasons near the coast. External doors get stainless or brass.
5. Not matching door weight. Weight ratings exist and generally assume three hinges fitted. Oversized and extra-wide doors also lever their hinges harder than the numbers suggest — when between sizes, size up.
6. Incorrect screw installation. Short screws, stripped heads, screws into soft reveal lining instead of solid frame timber, or skipped holes. The hinge is only ever as strong as its fixings: every hole filled, full-length screws, driven into sound timber.

Honourable mentions: painting over hinge barrels (the number one cause of stiff, squeaky hinges), mixing hinge types on one door, and ordering lift-off hinges without checking the handing.

12. Frequently Asked Questions

Are all hinges universal? No. Hinges vary by size, pin type, material, weight rating, and in some cases handing (lift-off hinges are left- or right-handed). Standard butt hinges in common sizes are broadly interchangeable in their recesses, but always match size, type and capacity to the door.

Which side should the hinge pin face? Hinge knuckles always face the direction the door opens. The security implication: on outward-opening external doors the knuckles face outside, so those doors need fixed pin or security-stud hinges — never accessible loose pins.

Can I replace just one hinge? For a damaged hinge, yes — match the size, type and finish exactly so all hinges share the load on a common axis. If one hinge has worn out from age, its partners are usually close behind; replacing the set restores the door properly.

Are stainless steel hinges better? For external and coastal applications, decisively yes — corrosion resistance is the whole game outdoors. Internally, quality plated steel or brass hinges perform equally well; stainless is a preference rather than a requirement.

What hinge size do I need? For most Australian doors: 100 × 75 mm. Go 75 × 50 mm only for lightweight internal and joinery doors, and step up to 125 × 100 mm or 150 × 100 mm for heavy, tall or oversized doors. Confirm against the hinge's stated weight capacity.

Can I paint door hinges? You can, but you shouldn't paint the barrel — paint in the knuckle is the leading cause of stiff, squeaky hinges. If a colour match matters, buy hinges in the finish you want (white, matt black and the full palette are readily available) rather than painting over the mechanism.

Why is my door dropping? Usually loose or stripped screws, worn plain-bearing hinges, too few hinges for the door's weight, or undersized hinges. Start by re-fixing with longer screws into solid timber; if the knuckles show visible wear or play, replace the hinges — ideally with ball bearing versions so it doesn't happen again.

What is a ball bearing hinge? A butt hinge with bearing races between the knuckles, so the door rides on rolling bearings instead of grinding metal on metal. Smoother, silent, and dramatically longer-wearing — the standard for heavy, external and high-traffic doors.

What are parliament hinges used for? Opening doors a full 180° so they fold flat against the adjacent wall, clearing architraves on the way. The classic application is French doors opening onto verandahs and patios.

How do I stop a squeaky hinge? Short term: a light lubricant worked into the barrel while swinging the door. If paint is in the knuckle, clean it out. If the squeak keeps returning, the bearing surfaces are worn — upgrading to ball bearing hinges fixes it permanently.
